Each compiler has its own libexec  directory   Normally libexec directory contains small helper programs called by other programs   In this case  gcc is looking for its own  cc1  compiler   Your machine may contains different versions of gcc  and each version should have its own  cc1    Normally these compilers are located on     usr local libexec gcc  lt architecture   lt compiler   lt compiler version  cc1   Similar path for g     Above error means  that the current gcc version used is not able to find its own  cc1  compiler   This normally points to a PATH issue

I had the same issue with gcc  gnat1  and it was due to the path being wrong  Gnat1 was on version 4 6 but I was executing version 4 8 1  which I had installed  As a temporary solution  I copied gnat1 from 4 6 and pasted under the 4 8 1 folder    The path to gcc on my computer is  usr lib gcc i686-linux-gnu   You can find the path by using the find command   find  usr -name  gnat1    In your case you would look for cc1plus   find  usr -name  cc1plus    Of course  this is a quick solution and a more solid answer would be fixing the broken path

This problem can happen if different versions of g   and gcc are installed       g   --version    gcc --version   If these don t give the result  you probably have multiple versions of gcc installed  You can check by using       dpkg -l   grep gcc   awk   print  2     Usually   usr bin gcc will be sym-linked to  etc alternatives gcc which is again sym-linked to say  usr bin gcc-4 6 or  usr bin gcc-4 8  In case you have gcc-4 6  gcc-4 8 installed     By changing this link you can make gcc and g   run in the same version and this may resolve your issue

I don t know why but i just renamed my source file COLARR C to colarr c and the error vanished  probably you need this  sudo apt-get install g

I had the same issue when forking with  python   the main reason is that the search path is relative  if you don t call g   as  usr bin g    it will not be able to work out the canonical paths to call cc1plus

You may have this issue as well if you have environment variable GCC ROOT pointing to a wrong location  Probably simplest fix could be  on  nix like system    unset GCC ROOT   in more complicated cases you may need to repoint it to proper location

Something went wrong with your GCC installation  Try reinstalling the it like this   sudo apt-get install --reinstall g  -5   In Ubuntu the g   is a dependency package that installs the default version of g   for your OS version  So simply removing and installing the package again won t work  cause it will install the default version  That s why you need to reinstall   Note  You can replace the g  -5 with your desired g   version  To find your current g   version run this   g   --version
