| Subject: [PATCH] interface/vcos/pthreads/CMakeLists.txt: fix build with |
| libexecinfo |
| |
| interface/vcos/glibc/vcos_backtrace.c uses execinfo.h which can be |
| provided by libexecinfo on uclibc or musl so link with it if needed to |
| avoid the following build failure: |
| |
| /home/peko/autobuild/instance-1/output-1/host/opt/ext-toolchain/bin/../lib/gcc/arm-buildroot-linux-uclibcgnueabi/10.3.0/../../../../arm-buildroot-linux-uclibcgnueabi/bin/ld: ../../build/lib/libvcos.so: undefined reference to `backtrace_symbols' |
