https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D220103 Fr=C3=A9d=C3=A9ric Fauberteau <triaxx@NetBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |triaxx@NetBSD.org --- Comment #46 from Fr=C3=A9d=C3=A9ric Fauberteau <triaxx@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 proc= ess produces the followings: [93/1124] Linking target glib/libglib-2.0.so.0.6200.3.
