Hi all I have been following the threads on compiling the GPC units for a while. A simple solution is an empty program that USEs all the units - build that program, and all the units are built automatically. Here is my version; {**********************************************************************} {**********************************************************************} {************** A program to build the main GPC units *****************} {*************** run 'gpc --autobuild -O2 build.pas' *****************} {**********************************************************************} {**********************************************************************} Program Build; USES crt, dos, dosunix, gmp, gpc, gpcutil, heapmon, overlay, pipe, ports, printer, regex, strings, system, trap, turbo3, windos; Begin End.
