Hello,
I have a problem using gcov and could not find a solution.
My system:
* gcc (GCC) 4.1.2 (Ubuntu 4.1.2-0ubuntu4)
* GNU Make 3.81
* ltmain.sh (GNU libtool) 1.5.22 Debian 1.5.22-4 (1.1220.2.365 2005/12/18 22:14:06)
* autoconf (GNU Autoconf) 2.61
* automake (GNU automake) 1.9.6
I have a libtool library for wich I want to test the coverage
of my unittests.
lib_LTLIBRARIES = libkonoco_base.la
check_PROGRAMS = unittest
[...]
unittest_LDADD = libkonoco_base.la
[...]
For both I have set the flags "-ftest-coverage" and "-fprofile-arcs"
via "./configure CXXFLAGS="-ftest-coverage -fprofile-arcs".
The lib compiles fine but compiling the unittest I got an error:
[...]
/usr/bin/ld: .libs/unittest: hidden symbol `__gcov_merge_add' in /usr/lib/gcc/i486-linux-gnu/4.1.2/libgcov.a(_gcov_merge_add.o) is referenced by DSO
/usr/bin/ld: final link failed: Nonrepresentable section on output
[...]
Without the flags for gcov everything works fine.
Is it possible to use gcov with libtool an shared
libraries? Or have I link to a certain lib?
Help would be great.
Regards,
