Both packaqes, however, require gcc-2.95.2-2 (June 10?) binutils-20000625 + my new ld.exe (*) (*) Several patches have recently been accepted into binutils CVS, and these are necessary for proper dll creation and linking. You can download a precompiled copy of ld.exe that includes these fixes from http://cygutils.netpedia.net/V1.1/linker/ld.exe.tar.gz. Presumably the next version of binutils officially released in cygwin-latest will include these fixes since they've all been accepted into CVS. Common to both packages: o import-lib libfoo.dll.a o stripped dll libfoo.dll o static-lib libfoo.a o cygwin-specific docs in /usr/doc/Cygwin/-.README o generic docs in /usr/doc/-/* o source archive already has the cygwin-specific patch applied o cygwin-specific README and PATCH are stored in the source archive, under /CYGWIN-PATCHES/* (although the patch has already been applied to the archive itself). o define -DZLIB_STATIC (and -DPNG_STATIC) to get the 'correct' #define's when compiling a .o that will be linked statically -- as well as using 'gcc -static' during the link step o no special -Ddefine options needed (or link options) needed to link to the dll Notes about zlib: I was able to successfully compile and pass 'make test' with all of the following: static dll static w/ contrib/asm686/match.S dll w/ contrib/asm585/match.S static w/ contrib/asm586/match.S dll w/ contrib/asm586/match.S static (using 'gcc -mno-win32') dll (using 'gcc -mno-win32') static w/ contrib/asm686/match.S (using 'gcc -mno-win32') dll w/ contrib/asm585/match.S (using 'gcc -mno-win32') static w/ contrib/asm586/match.S (using 'gcc -mno-win32') dll w/ contrib/asm586/match.S (using 'gcc -mno-win32') However, the binary package did not use any of the assembler code, and I didn't use 'gcc -mno-win32'. Notes about libpng: the patch here is slightly different than the one I submitted to png-implement. This version contains the CYGWIN-PATCHES stuff, and the Makefile install: is slightly different. However, I'm trying to get *most* of these changes into the official -1.0.8 release. I was able to compile and pass pngtest with all of the following: static dll static w/ pnggccrd (assembler stuff) dll w/ pnggccrd static using 'gcc -mno-win32' dll using 'gcc -mno-win32' static w/ pnggccrd using 'gcc -mno-win32' dll w/ pnggccrd using 'gcc -mno-win32' However, the binary package did not use -mno-win32, and did not include pnggccrd. A word of warning: pngtest will fail if it picks up the wrong libz.dll at runtime. Make sure you're using the one in the zlib-1.1.3-2 package and not an older copy or the one distributed with Suhaib's X11 stuff. (and don't scold me about dll versioning, Michael! ) Comments and test reports, anyone? --Chuck
