github.com/jwharm/java-gi@3844225632/modules/glib/src/main/java/org/javagi/util/Intl.java (L79)

looks like it's hardcoded. My actual dll name is:

$ which libgettextlib-0-26.dll
/mingw64/bin/libgettextlib-0-26.dll

Since I build from source, I can modify it to load my version. I could help if you have specific direction on how to load the library (like what you did with linux's tryLoadLibraryVersions()).

Thanks for the feedback!

I changed the Linux-specific tryLoadLibraryVersions() workaround to also be used on Windows and macOS, see PR #320. You can set your local library directory with the command-line parameter -Djavagi.library.path=/mingw64/bin/libgettextlib-0-26.dll. (See also the updated build.gradle in the java-gi-app-template repository for an example).

Can you test PR #320 and let me know if this fixes the issue?

I think it works. The only thing is both java.library.path and javagi.library.path does not work on Windows. I can load the library with PATH variable PATH="%PATH%;C:\\msys64\\mingw64\\bin", not with java.library.path and javagi.library.path.

I dig around and found this issue. They said it's intended.
https://bugs.openjdk.org/browse/JDK-8311090
https://bugs.openjdk.org/browse/JDK-8339367

But good enough since they are unrelated. You can close this issue when #320 is merged.
