gcc fails with spawn: No such file or directory

Question

I downloaded Ruben’s build of Cygwin GCC.

However upon running it seems unable to compile any files

$ touch foo.c

$ gcc foo.c
gcc: error: spawn: No such file         


        

Answer 1

I had the same error when I tried to extract a couple of executables from cygwin installation dirctory and copied them into another location.

strace shows me the file which was not found by spawn:

/lib/gcc/x86_64-pc-cygwin/6.4.0/cc1.exe

When I copied cc1.exe into the location relative to

/../lib/gcc/x86_64-pc-cygwin/6.4.0/cc1.exe

it works fine.
