While bootstrapping Prefix on Cygwin several exectables can't find shared libraries. On Windows such libraries are searched in $PATH, but the automatically generated $PATH on Prefix doesn't include $PREFIX/lib and $PREFIX/usr/lib, where many libs are installed. Reproducible: Always Steps to Reproduce: While bootstrapping Cygwin in prefix disable gen_usr_ldscript, as the script still breaks all. gen_usr_ldscript() { return 0 } Actual Results: Bootstrapping breaks, because libraries can't be loaded. Expected Results: Examples where shared libs are installed. */lib/libbz2.so */usr/lib/cyghistory6.dll */usr/lib/cygreadline6.dll */usr/lib/libperl.so */usr/lib/libz.so */usr/bin/cygcharset-1.dll* */usr/bin/cygexpat-1.dll* */usr/bin/cygffi-5.dll* I can't come up with a solution here, as I still don't know in detail which scripts generate the pathes. Workaround: Fix a) AND b). a) $PREFIX/etc/env.d/00basic PATH="/home/prefix/gentoo/usr/lib:/home/prefix/gentoo/lib:/home/prefix/gentoo/opt/bin:/home/ b) $PREFIX/usr/portage/profiles/prefix/windows/cygwin/1.7/x86/make.defaults EPREFIX="/home/prefix/gentoo" DEFAULT_PATH="${DEFAULT_PATH}:${EPREFIX}/lib:${EPREFIX}/usr/lib" Alternatively one could fix gen_usr_ldscript to generate working links to bin dirs, but that would be more work and isn't the real purpose of the scipt.
see https://github.com/gmt/gmt-cygwin-overlay/blob/master/portage_diffs/latest/eclass which contains a real solution (nb: and other non-solution stuff). At some point I will split this out and send it to the portage-dev mailing list but, as implemented, I think it's still a bit too ugly.
If Greg isn't driving this, I'm affraid noone will atm.
(In reply to Fabian Groffen from comment #2) > If Greg isn't driving this, I'm affraid noone will atm. Indeed, I am not behind the wheel on Cygwin ATM. I do plan to get back there sooner or later but many things need re-evaluating, a lot has changed.
