Anyone saw that too? Hello, Did you try to recompile it? According to the FHS, > If a C preprocessor is installed, /lib/cpp must be a reference to it, for historical reasons. But it seems that ArchLinux got rid of it recently (this file was present before the /lib -> /usr/lib transition but I do not have it anymore) So I guess that the following command would fix the problem > # ln -s /usr/bin/cpp /lib/cpp If the problem occurs in the latest version of spin, you should probably file a bug report to make spin use /usr/bin/cpp instead of /lib/cpp. Guillaume
