Failure when using crt unit

I get this failure when I try to compile a program that uses the crt unit program test; uses crt; ... begin .. end. I call gpc with this gpc -O --automake --extended-syntax test.pas -o test I get this failure: gpc: installation problem, cannot exec 'cpp': no such file or directory gpc1: gpc exits with status 1 /usr/lib/gcc-lib/i386-rehat-linux/2.8.1/crt.pas:345 '/usr/lib/gcc-lib/i386-rehat-linux/2.8.1/crtc.c' could not be compiled modul crt could not be compiled I have run the test with make which uses units the standard units which is descibed in the documentation of the beta relaese , should be read automatically. Does anybody seen this problem and what shal I do to fix it? Klaus F. Østergaard
