I am not a seasoned C programmer, but I compile some C code sometimes.
The last time I successfully compiled and run some C code I did it on the same system that I have now (the very same OS on the very same machine, no OS deinstallation/reinstallation happened). I did that about 2 months ago.
Now, if I try to compile even a very simple code like this:
#include <stdio.h>
main () {
printf("Hello");
return 0;
}
I get:
gcc: error trying to exec 'cc1': execvp: No such file or directory
Here is the gcc -v -Wall output:

I have no idea what has happened to my system.

I have also tried to compile the hello file with gcc-4.3 hello.c -o hello and it works. However, I can not run cmake commands and moreover downloading and building packages from the repositories fails with gcc: error trying to exec 'cc1': execvp: No such file or directory (I guess because cmake and dpkg do not know how to use gcc-4.3 instead of gcc).

Maybe the problem has something to do with CUDA installed on the system?
I have tried to re-install build-essential, but it did not help. I have also made an attempt to re-install the C preprocessor (cpp), but the system made a caution that it will remove a lot of core packages (like acpi-support, xserver-xorg-*, etc), so I did not do that.
env? Alsosudo ldconfig?gcc hello.c -o hello -Wallgcc -print-search-dirs? (2) Create a new user and try to compile the same thing. Maybe it's a configuration issue in the user home dir. (3) Have you tried with some other gcc version? I see you have installedgcc-4.1andgcc-4.3-- use them instead ofgcc.
