Subject: [PATCH] Link mcaptest with -lrt
The mcaptest tool uses the profiles/health/mcap.c source file, which
calls clock_getres(). This function is defined in librt, so mcaptest
should be linked against librt, otherwise one gets link failures such
as:
ld: profiles/health/mcap.o: undefined reference to symbol 'clock_getres@@GLIBC_2.2.5'
ld: note: 'clock_getres@@GLIBC_2.2.5' is defined in DSO [...]/sysroot/lib64/librt.so.1 so try adding it to the linker command line
[...]/sysroot/lib64/librt.so.1: could not read symbols: Invalid operation
collect2: error: ld returned 1 exit status
Makefile:4184: recipe for target 'tools/mcaptest' failed
