Dear, I am having a problem when compiling a program with options -ftest-coverage and -fprofile-arcs to run on an embedded system with ARM processor. I'm using a GCC cross-compiler (arm-elf) to compile the program. The errors is as follows: - undefined reference to `__gcov_merge_add' - undefined reference to `__gcov_init' is there any restriction on the use of these parameters for this type of processor? Thanks
