The command works from your shell, but doesn't seem to work from inside the Makefile. Can you force make to use bash as its shell (uncomment the SHELL= line at the beginning of the Makefile)? Does it work? Or maybe its is caused by a too recent gcc version (no idea why though), could you try an older one? You seem to have many versions of gcc on your system. I admit I'm puzzled. -- Jean Delvare http://www.ensicaen.ismra.fr/~delvare/
