After running configure, you must patch line 224 of install.sh to add the .exe extension as follows: dsttmp=$dstdir/#inst.$$#.exe ^^^^ A better patch could probably be made which detects Cygwin and automatically makes this adjustment, but I don't know how to do that. One other fact, which probably has no specific relevance to Cygwin: if you install gcc using --with-prefix=... (so that you don't disturb your existing 2.95.x installation), you get an advisory about the requirements for linking. This advisory is generated by a section of ltmain.sh starting at line 4892. Unfortunately, it comes in the middle of a huge amount of other make output which is probably best ignored. I installed GCC-3.0 twice before I noticed the advisory, and by the time installation was finished it had scrolled out of my buffer and was lost forever. I noticed enough to see that I could add "-L/usr/lib" to get things to link. If anyone knows how I can recover the complete information I'd love to know it. In any case I think it should be considered a bug that important advisories don't come at the end of the make process. -Dave >How-To-Repeat: Download gcc-3.0 configure using --with-prefix=/usr/local/gcc-3.0 make bootstrap make install >Fix: >Release-Note: >Audit-Trail: >Unformatted:
