--- Comment #46 from Frédéric Fauberteau <tri...@netbsd.org> ---
Hi,
I am not sure if the bug is really related but I think I have the same
symptoms. I am using the pkgsrc framework (from NetBSD) to build glib-2.62.3 on
FreeBSD 12.0-RELEASE-p12. I configured pkgsrc to use the basesystem Clang
compiler:
$ /usr/bin/clang --version
FreeBSD clang version 6.0.1 (tags/RELEASE_601/final 335540) (based on LLVM
6.0.1)
Target: x86_64-unknown-freebsd12.0
Thread model: posix
InstalledDir: /usr/bin
The meson configuration process completes without error. But the build process
produces the followings:
[93/1124] Linking target glib/libglib-2.0.so.0.6200.3.
FAILED: glib/libglib-2.0.so.0.6200.3

I tried to build it using the Clang version provided by pkgsrc:
$ /usr/pkg/bin/clang --version
clang version 9.0.0 (tags/RELEASE_900/final)
Target: x86_64-unknown-freebsd12.0
Thread model: posix
InstalledDir: /usr/pkg/bin
Since the problem is a linking error, I added LDFLAGS.FreeBSD+=
-fuse-ld=/usr/pkg/bin/ld.lld to use the LLD version provided by pkgsrc:
$ /usr/pkg/bin/ld.lld --version
LLD 9.0.0 (compatible with GNU linkers)
But I get similar errors:
ld.lld: error: undefined symbol: environ

By inspecting the object file, I got the following output:
