[Bug gcov-profile/35038] New: GCOV - using "--coverage" results in libgcov.a(_gcov.o) is referenced by DSO

[nanda dot anni at wipro dot com]

I am using gcc 4.1.1 on CentOS.

PerfStatsCli.o(.text+0x26a6): In function `global constructors keyed to
0_main':
/home/nanda/galaxy/tsunami/PerfStats/cli/PerfStatsCli.cpp:664: undefined
reference to `__gcov_init'
PerfStatsCli.o(.data.rel+0x48): undefined reference to `__gcov_merge_add'
collect2: ld returned 1 exit status
make: *** [perfstats] Error 1

Then I tried linking with -lgcov and now I get below error.

-L/home/nanda/galaxy/lib -lgcov -lPerfStats -L /usr/local/lib -lpthread -ldl
-dynamic
/usr/bin/ld: perfstats: hidden symbol `__gcov_init' in
/usr/local/gcc-411/lib/gcc/x86_64-unknown-linux-gnu/4.1.1/libgcov.a(_gcov.o) is
referenced by DSO

I have tried using gcc 4.2.2 and also latest libtool(1.5.24 )but could not
resolve the issue.

I am unable to proceed further to get the code coverage for my application
(product).
Hence it is critical to fix this issue.
I had posted a query to gcov maintainers but their response was that, there
might be a bug in gcc itself. Hence reported this bug.

Try using -fprofile-arcs as linker option instead of -lgcov. If that doesn't
help this is most likely a bug in gcc. Please report to the gcc maintainers.

Coverage and shared libraries do not mix easily.

I am able to built shared objects. But, while building the executable binary
using the shared objects. I see the error "hidden symbol `__gcov_init' in
/usr/lib64/gcc-lib/x86_64-suse-linux/3.3.3/libgcc.a(_gcov.oS) is referenced by
DSO".

Some one please help me.
