Hello, I recently started working on a new code base that consists of thousands of C source files, and a somewhat complicated Makefile structure. One of my team's requirements was to be able to use code coverage tools on the new code base. Over the last few days, I have been working to try and get GCov working on the new image, but I've hit some snags. First, let me give an overview of how the image is built. The source code is broken up into distinct modules. Each source file is compiled into an object file (.o). The object files for a given module are then compiled into a static library (.a). Finally, all of the static libraries are linked together to create the executable. In order to obtain coverage information, I compiled a few of the object files with the "-fprofile-arcs -ftestcoverage" options (we're using GCC 3.3.6). Originally, the coverage data was not getting created, which led me to discover that the build was using ccache. Thus, to bypass "ccache" and ensure that the object files were compiled locally, I set the "CCACHE_DISABLE" environment variable to 1. After rebuilding, I discovered that the appropriate "*.bb" and "*.bbg" files were created. Now, I need to run the executable on a different machine than my build machine. We can call the new machine "the simulator." The simulator has my entire workspace mounted. Thus, the simulator still has access to all of the object files, static libraries, and source code. When executing I must log into the simulator as root. Thus, I have different permissions (i.e. root doesn't have write access to all of my object directories). I have tried addressing this by doing a "chmod 777" on the object file directories that contain my *.bb and *.bbg files to ensure that root is able to write to that directory. After running the image, the necessary *.da files are not getting created. I've read some suggestions that I may need to use the -lgcov flag when linking the static libraries to the main executable. When adding this flag, I started getting an error saying that the linker "cannot find -lgcov." I looked around our source tree, and I couldn't find a version of libgcov.a for our gcc 3.3.6 Is including "-lgcov" when linking all of our static libraries into the executable required with gcc 3.3.6? If so, can anyone point me to where I can obtain this library? I downloaded and checked the gcc-3.3.6.tar, but I didn't find a libgcov.a file. Does anyone have any other suggestions besides including "-lgcov?" Thanks, Ryan
