No. The Cygwin utility for 7z archives is p7zip, but that's one of the packages that hasn't been ported to 64-bit Cygwin yet.
What's the best way to contribute to help this along? I just downloaded the p7zip source package and figured out what needs to change to get the cygport file to build cleanly in 64-bit Cygwin: 1. One of the patches doesn't apply correctly because a man file, man1/7zr.1, has the wrong line endings. Running dos2unix on that man file and re-packing the source tarball fixed that. 2. In src_compile() in the cygport file, the line cp makefile.cygwin_asm makefile.machine is resulting in an x86 assembly file getting pulled in, which fails to link in 64-bit Cygwin. There is an x86_64 assembly version of the same file included in the source tarball which could be used instead, but the easier patch is to instead use a C version of the file. There may be some performance penalty here, but it's a one-liner patch to the cygport file: [ `arch` = x86_64 ] && cp makefile.cygwin makefile.machine added after the previous "cp" line. Can anyone offer guidance for how to proceed in creating a 64-bit version of this package now that I've pointed out what needs to be fixed?
