GCOV Loading error.

GCOV Loading error.

[Akshya Chhabra]

Hi,
   I am trying to setup GCOV in my env for that I have added these
flags in for compilation and linking.

CFLAGS_linux= -m32 -fPIC -g -Wall -fprofile-arcs -ftest-coverage

LDFLAGS_linux= -m32 -shared -L/usr/lib -fprofile-arcs

After this I am able to compile properly and the corresponding .o and
.gcno files are generated.

But when I am trying to start my process it is giving me this error
while starting the process.


ERROR bad load_module for:
"/u02/sms/achhabra/B6400_BRANCH/sms_bins/lib/fm_sir_utils.so":
/u02/sms/achhabra/B6400_BRANCH/sms_bins/lib/fm_sir_utils.so: undefined
symbol: __gcov_merge_add

Can you please help me in fixing this issue asap.

After fixing the above issue I am facing this issue now ..


For me the .gcda files is itself not getting generated any where in my env. 
I hope I have not missed anything . I am working with shared libraries. Any 
pointer ???

for me the .gcno is generated properly after compilation and the .gcno and 
.so is in the same directory . The main process which I am running is 
loading this shared library and calling it for during various operations. 
With this main process I am doing those operations but somehow the .gcda is 
not getting generated because of which I am not able to run gocv on the 
source file.
