Hi guys, I am having a serious problem.I didn't find any satisfactory solution anywhere. So pls help me if u can... I generated a dynamic library with this options -fprofile-arcs and -ftest-coverage. Idea behind is to use gcov and get the coverage information for my dynamic library which I am calling SepiaRT.Seems it build successfully. After that when I try to build an application called findsepia which uses some of the functions in my instrumented library SepiaRT, I get this error message. Linking findsepia for Linux >> /usr/bin/ld: ../../../../../debug_rhel3_64/bin/findsepia: >> hidden symbol '__bb_init_func' in /usr/lib/gcc-lib/x86_64-redhat-linux/3.2.3/libgcc.a(_bb.oS) is refer >> enced by DSO collect2: ld returned 1 exit status >> gmake[4]: *** [../../../../../debug_rhel3_64/bin/findsepia] Error 1 >> gmake[3]: *** [dep] Error 2 >> gmake[2]: *** [findsepia.subdir] Error 2 >> gmake[1]: *** [tools.subdir] Error 2 >> make: *** [../../parts/sepia.subdir] Error 2 I am using gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-34).
