Hi, I did some hack work in the configure script and found that it assumes the build platform to be UNIX type. This can be found in various places for example: The executable extension variable "ac_exeext" is not set for MingW32 on NT. The path seperator is ";" and not ":" as in UNIX. These were the two major problems I faced. I modified the configure script and the generated config.status to fix the above stated problem. I was able to get Makefile and GNUMakefile for all folders with out any errors or warning. When I do a "make" or a "gmake", it fails in "lib-src" folder stating the following error: cd ./lib-src && gmake all GNUmakefile:130: *** multiple target patterns. Stop. gmake[1]: Entering directory `F:/tmp/XEmacs- Build/xemacs-21.5.3/lib-src' gmake[1]: Leaving directory `F:/tmp/XEmacs-Build/xemacs-21.5.3/lib-src' gmake: *** [lib-src] Error 2 And line 130 has the build target for getopt.o and it is specified only once. I thought that "^M" must be the culprit. It was not. If any one is interested in porting XEmacs to build using MinGW32, please let me know. -- +-----------------------------------------------------------+ | Remaining time multiplied by distress is CONSTANT | +-----------------------------------------------------------+
