cfr. #5716
The use of
--disable-dlopenwas originally introduced in #186 to fix a problem withRmpi(see also https://www.mail-archive.com/[email protected]/msg10852.html).I retested the installation of
Rmpion top of bothfoss/2017bandfoss/2016aafter rebuilding theOpenMPIcomponent of those toolchains without--disable-dlopen, and I could not reproduce theRmpiproblem, so it seems like our original motivation for including--disable-dlopenis no longer valid anyway...cc @m0zes, @chrissamuel, @akesandgren
