gcov out of memory / mismatched version?

Question

Just trying to get gcov up and running, getting the following error:

$ gcov src/main.c -o build
build/main.gcno:version \'404*\', prefer \'407*\'

gcov: out of m         


        

Answer 1

I just had the same problem on my machine.

Make sure your versions of gcov and the compiler you use match.

I had this exact problem when compiling with g++-4.7 and I had gcov 4.6.

On my machine sudo apt-get install ggcov got me the latest version. I then had to sudo ln -sf /usr/bin/gcov-4.7 /usr/bin/gcov to make gcov point in the right place.
