Hello GCC Experts,
I am an engineer trying to run gcov for our unit tests. We have a couple of
DLLs and a few static libraries.
I am having trouble linking the Test program that links in the DLLs. I have
the following in the Cmake files:
IF( "${COVERAGE}" STREQUAL "TRUE" )
LINK_DIRECTORIES(/usr/lib64/gcc-lib/x86_64-suse-linux/3.3.3)
TARGET_LINK_LIBRARIES( NWATest analytics TestUtils ${SYSTEM_LIBS} )
ENDIF( "${COVERAGE}" STREQUAL "TRUE" )
I have similar lines for all make files that create TARGET_LINK_LIBRARIES.
But I get the following errors:
/bin/ld: NWATest: hidden symbol `__gcov_init' in
/usr/lib64/gcc-lib/x86_64-suse-linux/3.3.3/libgcc.a(_gcov.oS) is referenced by
DSO
COULD SOMEONE PLEASE HELP!!! I have not found ANY ONLINE documentation or
solutions on message boards.
Many Thanks. PLEASE SEE MORE INFO BELOW.
