what is the output of `which cpp`? normally, /lib/cpp (what pops up in your error message) should be a symbolic link to /etc/alternatives/cpp ` like this: $ file /lib/cpp /lib/cpp: symbolic link to `/etc/alternatives/cpp' $ file /etc/alternatives/cpp /etc/alternatives/cpp: symbolic link to `/usr/bin/cpp'
and now /usr/bin/cpp should exist and be what it should be $ which cpp /usr/bin/cpp $ cpp -v Using built-in specs. COLLECT_GCC=cpp Target: x86_64-linux-gnu ...
