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'
