Description Ramu 2009-04-01 13:44:56 UTC 
Problem:
g++ fail to build execuable by linking .so files built with options -Wall -fprofile-arcs -ftest-coverage

I am able to built shared objects with g++ using options -Wall -fprofile-arcs -ftest-coverage. But, while building the executable binary
by linkng 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".

I dont see the same problem for .c files building with gcc and same options.
Some one please help me. Please let know if you need any more info.

How is the libraries build?  While linking do you use -fprofile-arcs -ftest-coverage?

Hello,

Thanks for your response.

Used options "-Wall -fprofile-arcs -ftest-coverage"  for compilation. I see the error reported.
After your reply, I have tried using both the mentioned flags both in compilation and linking. But, still I see the same error.

BTW, I think these are complilation flags not the linking flags Am I not right ?

Regards,

Guessing you're missing LDFLAGS="-Wall -fprofile-arcs -ftest-coverage".
Thus closing the bug as invalid.
