I want to compile the ruby source so I can have a play with the source and try creating some extensions :) So far I have Eclipse IDE with CDT (C Development Tools) and SVN installed, as well as Mingw32 which contains gcc, g++ and mingw32-make. 1. Is this a reasonable setup for windows? 2. What should the makefile look like, I tried running the makefile.in but I get: mingw32-make -f makefile.in clean all makefile.in:12: *** missing separator. Stop. Looking at the readme I should use ./configure to generate a makefile, but of course it does not run on win32, I tried running it on Cygwin but it didnt make anything. Many thanks, Pete. -- Posted via http://www.ruby-forum.com/.
