python + gcov

[labrach]

Hi
I want to profile (and analyse coverage) some c++ code imported as a
python module
I've compiled python (2.4.2) with gcc 3.4.3 and flags=-Wall -fprofile-
arcs -ftest-coverage in order to use gcov. However, the python binary
does not generate any coverage file (such than *.gcno, gcda) during
execution.
any tips ?
or may be another method to profile c++ wrapped modules within
python ?

thanks

Some precisions :
I've forced the configuration options with the followings flags in the
Makefile.pre :
OPT='-Wall -fprofile-arcs -ftest-coverage -pg'
BASECFLAGS='-Wall -fprofile-arcs -ftest-coverage -pg'
LDFLAGS='-Wall -fprofile-arcs -ftest-coverage -pg'
XLINKER='-Wall -fprofile-arcs -ftest-coverage -pg'

But, the coverage files are not produced by a simple : python -c
'print "Hello"'
while the gmon.out is produced

Another questions is:
the wrapped c++ module is also compile with -pg flags (and -fprofile-
arcs -ftest-coverage as well) but the profile information does not
appear in the gmon.out
Do I need to make a static extension of my imported module to profile
it ?

thanks anyone ...

I always bit the bullet and finally just did that.
