From: Fabrice Fontaine Date: Mon, 10 Feb 2020 17:41:27 +0000 (+0100) Subject: package/ogre: link with libatomic when needed X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=bc88757481534b129b34b1890ef1569a71308229;p=buildroot.git package/ogre: link with libatomic when needed On some architectures, atomic binutils are provided by the libatomic library from gcc. Linking with libatomic is therefore necessary, otherwise the build fails with: /home/test/autobuild/run/instance-1/output-1/host/lib/gcc/xtensa-buildroot-linux-uclibc/8.3.0/../../../../xtensa-buildroot-linux-uclibc/bin/ld: ../../lib/libOgreMain.so.1.12.0: undefined reference to `__atomic_fetch_add_8' This is often for example the case on sparc v8 32 bits.
