Meson doesn't link to Boost correctly on NetBSD #4464

Open nomis opened 6 years ago

nomis commented 6 years ago

On NetBSD 8.0, Meson doesn't link executables to Boost correctly because it's not possible to execute them without a custom LD_LIBRARY_PATH:

/usr/pkg
$ meson --version
0.48.1
$ ninja --version
1.8.2
$ g++ --version

Netbsd may need the rpath workaround some other BSDs do.

This doesn't happen on FreeBSD/OpenBSD/DragonFlyBSD, I'm able to build and run the application on all of those systems (with b_lundef/b_asneeded disabled on OpenBSD).

What rpath workaround do I need to specify with Meson?

jpakkane commented 6 years ago

It would appear that /usr/pkg/lib is not in the default library search path on NetBSD. Is there official documentation on how programs that use libraries installed in that directory should work? Is it like /usr/local/lib on Linux where the end user is expected to set LD_LIBRARY_PATH or are build systems expected to add the appropriate rpath entry pointing to /usr/pkg/lib whenever compiling code that uses those libraries?

dcbaker commented 6 years ago

I guess we should go introduce ourselves to the various BSDs and start asking songs of these questions. I guess I'll go do that tonight or Monday unless someone beats me to it.

This is documented at http://www.netbsd.org/docs/elf.html:

The primary directory locating mechanism is the ``rpath'' search list contained within the executable image.
