Cross-configuring Lsof

Introduction

============

Lsof cross-configuration is useful when the target dialect or target

dialect version for which lsof is to be configured and built differs

from the one on which the Configure operation is done.

Marty Leisner <[email protected]> suggested the method

described here for lsof cross-configuration, and he supplied

modifications to the Configure script for cross-configuring Linux

lsof.

Marty says:

"I used this to successfully compile (lsof) on the same machine

for (Linux) 2.0.30 and 2.1.42. (I normally don't bring up a

2.1.42 machine all the time). Also it (the 2.0.30 system)

doesn't have much storage and compiles on it are slow.

Set LSOF_VERS if it's not the (version of the) current system.

(Actually, you should get the version out of include/linux/version.h.)

Define LINUX_KERNEL to (the path) where the kernel sources

are (located). (No longer necessary as of lsof revision 4.53.)

This should work on most systems; they put a kernel in

/usr/src/linux, which is the default.

Now I can just do:

LINUX_KERNEL=/some/other/kernel LSOF_VERS=2142 ./Configure linux

Comments? Its very convenient when running multiple kernels.

(It would be (have been) very handy when the structures changed

between 2.0.2* and 2.0.30 , or whatever.)

I run multiple OSes at a time (not to mention multiple

architectures. It's very pleasant to cross-build either

operating systems or versions."

So, the situation is that you have lsof sources on a UNIX dialect

version, and you want to configure them to build lsof for some

other version of the same dialect, or perhaps for some other UNIX

dialect altogether.

The Cross-Configure Method

==========================

The lsof cross-configure method uses environment variables to tell

the lsof Configure script about the target dialect. The environment

variables may specify alternate locations for Configure to examine

when it determines characteristics of the target, or they may

specify the values Configure would discover when it examined the

target's characteristics.

Consult each environment variable description for the UNIX dialect

in which you're interested to see how it affects the operation of

the Configure script.

The number and values of the variables differ by dialect. Each

variable begins with an upper case version of the dialect's Configure

abbreviation -- e.g., AIX for aix or aixgcc, LINUX for linux,

UW for uw (UnixWare), etc.

Of course, the UNIX dialect's version is probably different from

that of the system on which you're doing the cross-configuration,

so you will need to specify the new version, too. For example, to

configure for FreeBSD 3.0 on a 2.1.7 system, where the standard

3.0 header files are in /3.0/usr/include and the 3.0 system sources

are in /3.0/sys, do this:

LSOF_VERS=300 LSOF_INCLUDE=/3.0/usr/include \

FREEBSD_SYS=/3.0/sys Configure -n freebsd

General Environment Variables

=============================

There are some environment variables whose names don't begin with

an upper case rendering of a dialect abbreviation. Generally they

apply to all dialects.

AFS_VICE is for AFS configuration. It need be set only if

lsof supports AFS on your dialect and you want to

specify an alternate path to the VICE files.

default: /usr/vice

LSOF_AR is the path to and arguments for the library archive

application that is used to build the lsof library,

liblsof.a. When this value is placed in the library

Makefile as the contents of the AR make string, it is

followed by the path to the library and the relative

paths of the library module

default: ar cr

LSOF_ARCH is the architecture type string for the system.

Usually this is the output of `uname -m`. Consult

the Configure script for details. The LSOF_ARCH

value may have to be quoted if it contains spaces.

default: auto-detection (e.g., from `uname -m`)

LSOF_BLDCMT may be used to introduce a builder's comment into

lsof's -v output. It defaults to the null string,

causing no builder's comment to appear in -v output.

default: none

LSOF_CC is the path to the C compiler. You may need to

specify it if your C compiler is in a non-standard

place, not found by your path. If you specify a

compiler different from the expected default, you

may have to change the compile time flags by

specifying new CFGF, CFGL, and DEBUG strings on

the make command line.

default: normally cc, but some dialects have other

defaults and some have auto-detection.

Check the dialect stanza in the lsof Configure

script to see how LSOF_CC is set by default.

LSOF_CCV is the C compiler version. You should specify it

if you have specified a compiler path in LSOF_CC.

default: the lsof Configure script knows how to find

the version number of gcc and some other

dialect-specific compilers.

Check the dialect stanza in the lsof Configure

script to see how lsof_CCV is set by default.

LSOF_CFGF may be used to specify additional configuration values

that will appear in the CFGF string of the Makefile.

LSOF_CFGL may be used to specify additional library specifications

that will appear in the CFGL string of the Makefile.

LSOF_HOST may be used to specify a value in lsof's -v output

other than the name of the host where lsof was

built. A value of "none" inhibits host name display

in -v output.

default: the dialect's host name application -- e.g.,

hostname or uname -n

LSOF_INCLUDE is the path to the standard header files. You may

need to specify it if you want Configure to test

header files in a tree different from /usr/include,

and you want to compile lsof from the header files

in that different tree.

LSOF_LOGNAME may be used to specify a value in lsof's -v output

other than the one in the LOGNAME environment

variable for the login name of the person who built

lsof. A value of "none" inhibits login name display

in -v output.

default: the LOGNAME environment variable

LSOF_MAKE is the path to the make command.

deafult: the output of `which make`, if it is not NULL;

otherwise the string "make".

LSOF_MKC may be used to specify an alternate method of

connecting dialect sources to the top-level lsof

directory. See 00PORTING for more information.

default: ln -s

LSOF_RANLIB may be used to specify an alternate command for the

randomizing of the lsof library.

default: ranlib for most dialects

none for: IBM AIX; HP-UX; SCO OpenServer; Solaris

and SCO|Caldera UnixWare

LSOF_SYSINFO may be used to specify a value in lsof's -v output

other than the standard system identification --

e.g., output from uname. A value of "none" inhibits

system information display in -v output.

default: the dialect's standard system identification

application output -- e.g., uname, sysinfo

LSOF_USER may be used to specify a value in lsof's -v output

other than the one in the USER environment variable

for the login name of the person who built lsof.

A value of "none" inhibits login name display in

-v output.

default: the USER environment variable

LSOF_VERS is the target dialect version number. It must be

stated in the dialect's form -- e.g., FreeBSD 2.0.5

is given as 205, Solaris 7 as 70000, etc. The

table, "Abbreviations, Variable Prefixes, and

Version Numbers," in this file gives the form for

LSOF_VERS for each dialect lsof supports.

default: auto-detection (e.g., from `uname -r`)

LSOF_VSTR is the version string from which LSOF_VERS is

derived. Usually this is the output of `uname -r`

or `uname -v`. Consult the Configure script for

details. The LSOF_VSTR value may have to be quoted

if it contains spaces.

default: auto-detection (e.g., output from

`hostname`, `uname -r`, or `uname -v)

Make Strings

============

The CFGF, CFGL, and DEBUG strings can be specified on the make

command line to change default values placed in the top-level and

library Makefiles by Configure. For example, Configure usually

defines the compiler optimization level to be -O, but you can change

that with "DEBUG=-g" on the make command -- e.g.,

$ make DEBUG=-g lsof

Similarly, the CFGF string contains miscellaneous compile-time

options, and CFGL contains loader options. Consult the Makefiles

generated by Configure for the values it defines by default for

CFGF and CFGL.

As an example, Configure might define CFGL to be "-L./lib -llsof -w"

for NextStep 3.1; to remove "-w", use this make invocation:

$ make CFGL="-L./lib -llsof"

Abbreviations, Variable Prefixes, and Version Numbers

=====================================================

The following table describes the relationship between Configure

abbreviations, environment variable prefixes, and lsof UNIX dialect

version numbers. The lsof UNIX dialect version number must be

declared exactly in the listed form when supplied via the LSOF_VERS

environment variable.

Dialect-Specific Environment Variables

======================================

Here are the dialect-specific environment variables, listed

alphabetically. The first part of any environment variable will

be the dialect abbreviation, as specified to Configure, converted

to upper case characters. See the `Configure -help` output for a

listing of the abbreviations.

AIX_ARCH specifies the AIX architecture when the AIX version is

5.0 or higher. A value of "" signifies POWER; "ia64",

64 bit x86 (Itanium).

default: none (tested via `uname -a`)

AIX_HAS_AFS specifies the state of AIX ADS support when the AIX

version is 4.3.3 or lower. (Lsof doesn't support AFS

above AIX 4.3.3.) A value of "" allows the Configure

script to determine the AFS support state; "no",

disables AFS support; and "yes", forces the enabling of

AFS support.

default: none (tested via presence of AFS files and the

lsof AFSConfig shell script)

AIX_KERNBITS specifies the kernel bit size, 32 or 64, of the Power

architecture AIX 5.x kernel for which lsof was built.

default: determined by the Configure script with a test

program that uses <sys/systemcfg.h> macros.

AIX_USHACK If this environment variable has a value of "Y" or "y",

and if the aixgcc Configure abbreviation is selected,

the AIX 4.1 and greater gcc user structure hack is

activated; any other non-NULL value, it's not set; a

NULL value, it's tested by compilation.

default: none (tested by compilation)

DARWIN_XNUDIR If this environment variable has a value, the value is

used as the path to the Darwin XNU kernel source code.

default: none (entry requested)

DARWIN_XNU_HEADERS If this environment variable has a value, the value is

used as the path to the Darwin XNU kernel header files.

This path would match the DSTROOT environment variable

used when a "make installhdrs" was executed from the

Darwin XNU kernel source directory.

default: none

DU_ADVFSV specifies the DEC OSF/1, Digital UNIX, or Tru64 UNIX

ADVFS file system version -- e.g., 200 for 2.0, 400

for 4.0, etc.

pstat, to be used.

default: determined by testing for the

/usr/include/sys/pstat subdirectory

HPUX_BOOTFILE specifies the file in which lsof's Configure script can

find kernel information. This specification may be

useful for defining the path to a copy of /stand/vmunix

that has been processed by pxdb or q4pxdb.

default: /stand/vmunix

HPUX_CCDIR1 specifies the first directory where Configure might

find an HP-UX C compiler. This is ignored when

LSOF_CC has been specified.

default: /bin

HPUX_CCDIR2 specifies the second directory where Configure might

find an HP-UX C compiler. This is ignored when

LSOF_CC has been specified.

default: /usr/ccs/bin

HPUX_HASONLINEJFS If this environment variable has a value of "Y" or "y",

the HASONLINEJFS definition will be enabled in the

Makefile CFLAGS. That will cause dnode1.c to use an

alternate vx_inode.h header file in the hpux11 sub-

directory of dialects/hpux/kmem.

default: determined using nm and grep

HPUX_IPC_S_PATCH If this environment variable has a value of "1", the

ipc_s structure of the HP-UX 11 kernel is assumed to

have an ipc_ipis member, but it is assumed the ipis_s

structure lacks the ipis_msgsqueued member; "2", ipc_s

has ipc_ipis, but ipis_s has ipis_msgsqueued; "n" or

"N", ipc_s lacks ipc_ipis; any other non-NULL value is

considered an error; a NULL value, HPUX_IPC_S_PATCH is

determined by testing.

default: /usr/lib

HPUX_LIBC2 specifies the second directory that might contain the

HP-UX C library, libc.sl.

default: /lib

HPUX_RNODE3 If this environment variable has a value of "1", the

Configure script will define HASRNODE3 in the Makefile

CFGF flags. If it is defined, but not "1", Configure

will not define HASRNODE2.

default: determined using `nm -x /stand/vmunix` and

`grep r_fh3 /usr/include/nfs/rnode.h`

HPUX_X25DIR specifies path to the HP-UX X25 directory that contains

configuration header files.

default: /etc/conf

LINUX_CONF_CC specifies the location of the C compiler to use during

the running of the Configure script:

default: the value of the LSOF_CC variable, if defined,

or cc

LINUX_HASSELINUX If this environment variable has a value of "Y" or "y",

Configure unconditionally activates SELinux support.

If it has any other value, Configure unconditionally

inhibits SELinux suport.

Default: assumed to be "Y" if <selinux/selinux.h>

exists

LINUX_INCL specifies the path to the header file tree:

default: /usr/include

LINUX_LSEEK If this environment variable has a value of "Y" or "y",

Configure uses Makefile.lseek in place of Makefile in

order to enable use of the private lseek() function for

2.1.x kernels; any other non-NULL value, Makefile.lseek

will isn't used; a NULL value, the alternate lseek()

need is determined by compilation.

default: determined by test program

LINUX_VERSION_CODE specifies the value of the LINUX_VERSION_CODE in the

same decimal form as found in the LINUX_VERSION_CODE

#define of /usr/include/linux/version.h:

default: the value of LINUX_VERSION_CODE in

/usr/include/linux/version.h

NETBSD_SYS specifies the path to the NetBSD system source

directory.

default: /usr/include

NETBSD_UVM If this environment variable has a value of "Y" or "y",

the NetBSD system uses the UVM virtual memory system;

any other non-NULL value, it does not; a NULL value,

it will be determined by the contents of /etc/mk.conf.

default: tested by grep'ping /etc/mk.conf

OPENBSD_SYS specifies the path to the OpenBSD system source

directory.

default: /sys

OPENBSD_UVM If this environment variable has a value of "Y" or "y",

the OpenBSD system uses the UVM virtual memory system;

any other non-NULL value, it does not; a NULL value,

it will be determined by examining /bsd.

default: tested by grep'ping `nm /bsd` output

OSR_CFGF The value of this environment variable is made the

initial value for the compiler flags the lsof Configure

script constructs for the Makefile CFGF macro.

default: ""

OSR_CFGL The value of this environment variable is made the

initial value for the loader flags the lsof Configure

script constructs for the Makefile CFGL macro.

default: ""

OSR_STATLSTAT If this environment variable has a value of "Y" or "y",

HAS_STATLSTAT is defined in the Makefile's CFGL string;

any other non-NULL value, it's not defined; a NULL

value, it is determined with nm and grep.

default: determined with nm and grep

SOLARIS_23P101318 If this environment variable has a non-NULL value, the

value is interpreted as the patch level of the Solaris

2.3 P101318 patch.

default: pkginfo tested with grep

SOLARIS_24P101945 If this environment variable has a non-NULL value, the

value is interpreted as the patch level of the Solaris

2.4 P101945 patch.

default: pkginfo tested with grep

SOLARIS_24P102303 If this environment variable has a non-NULL value, the

value is interpreted as the patch level of the Solaris

default: pkginfo tested with grep

SOLARIS_26PR_GWINDOWS If this environment variable has a value of "Y" or "y",

the HASPR_GWINDOWS definition is set in the Solaris 2.6

and 7 Makefile's CFG string; any other non-NULL value,

it's not set; a NULL value, it's tested by compilation.

default: tested by compilation

SOLARIS_26PR_LDT If this environment variable has a value of "Y" or "y",

the HASPR_LDT definition is set in the Solaris 2.6

Makefile's CFGL string; any other non-NULL value, it's

not set; a NULL value, it's tested by compilation.

default: tested by compilation

SOLARIS_CCDIR specifies the path to the Sun C compiler -- i.e., when

`Configure solariscc` is used. This is ignored when

LSOF_CC has been specified.

default: /opt/SUNWspro/bin

SOLARIS_INSTR specifies the Sun C compiler target instruction set

when building lsof for a 64 bit kernel -- i.e., when

the Configure abbreviation is "solariscc". Possible

values include amd64 and sparcv9. This is ignored when

the Configure abbreviation is "solaris" -- i.e., the

compiler is gcc.

default: tested with /bin/isainfo -k

SOLARIS_KERNBITS specifies the number of bits in the Solaris 7, 8, 9 or

10 kernel: 32 or 64.

default: tested by compilation

SOLARIS_VXFSINCL This environment variable defines the path to the

header files of the VxFS 3.4 or greater version. If

SOLARIS_VXFSINCL is not set, the default is used.

default: VxFS < 4.0:

/opt/VRTSvxfs/include

VxFS 4.0 and above:

/opt/VRTSfssdk/<version>/include

SOLARIS_VXFSLIB This environment variable defines the path to the

VxFS 3.4 or greater utility libraries, libvxfsutil.a

(32 bit) and libvxfsutil64.a (64 bit). If

SOLARIS_VXFSLIB is not set, the default is used.

Note: end SOLARIS_VXFSLIB at the "/lib" component; do

NOT put "/sparcv9" at its end. The lsof

Configure script will add "/sparcv9" if it is

required; hence, if Configure finds that

"/sparcv9" is needed, your SOLARIS_VXFSLIB

directory tree must have a sparcv9 subdirectory.

default: `dirname $SOLARIS_VXFSINCL`/lib

SUN_AFSAPATHDEF specifies the path to the AFS library modload file

for either Solaris or SunOS.

default: /usr/vice/etc/modload/libafs
