The complete commandline's that I run are :
CFLAGS='-fprofile-arcs -ftest-coverage' CXXFLAGS='-fprofile-arcs
-ftest-coverage' LDFLAGS='-fprofile-arcs -lgcov' ./autogen.sh
--enable-python=internal --without-system-libs --without-system-headers
gb_GCOV=YES verbose=t make --output-sync=target
gb_GCOV=YES verbose=t make check -k --output-sync=target
I recently started a thread  that is about the (complete, not partial)
build with gcov failing for me if I only set 'gb_GCOV=YES' on the make
commandline. The build succeeds for me if I also set the required *FLAGS on
the autogen commandline. The failing parts when only using 'gb_GCOV=YES'
were/are 'liborcus' and 'expat'. Skia (I think) initially also broke the
build, but that was because of conflicts between clang and gcc , which
was resolved when I uninstalled clang. If I understand correctly, it was
intended to force skia to always be built with clang, but - intended or not
- at least on Linux it falls back on gcc (or skia gets skipped perhaps).
When looking at 'coverage.sh', it seems it only covers specific parts of
the build, and not everything, so perhaps it doesn't build the parts that
fail for me when not setting the additional *FLAGS ?
Anyway, if you feel that setting the additional *FLAGS in addition to
'gb_GCOV=YES' is not the right way to address the problem of the full build
with gcov failing for me, then perhaps we should revisit that thread ,
before we continue looking at why 'make check' fails for me ?
