Description of problem: I am trying to cross-compile a program for Windows, and it needs a library that I've already cross-compiled. I set PKG_CONFIG_PATH to point to the directory that contains the .pc file for that library, but mingw32-configure unsets PKG_CONFIG_PATH and I can't compile my program Version-Release number of selected component (if applicable): mingw32-filesystem-97-1.fc18.noarch Additional info: This can be easily fixed by removing the following line from /etc/rpm/macros.mingw32 unset PKG_CONFIG_PATH; \ I've verified that if PKG_CONFIG_PATH isn't set, then mingw32-configure shows it as empty, but if it is configured, my program compiles correctly, using both public mingw libraries and my private library.
I've just noticed that, at least according to the rpm changelog, this was already supposedly done back in 2011. Not sure how it got back in there.
The unset is really required here. When building RPMs the PKG_CONFIG_PATH environment variable gets set by rpm automatically so that it points to %{_libdir}/pkgconfig. As we don't want to use any native libraries when cross-compiling this environment variable has to be unset first before running mingw32-configure (or %mingw32_configure in RPM terms)
This message is a reminder that Fedora 18 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 18. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '18'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 18's end of life. Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 18 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior to Fedora 18's end of life. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 18 changed to end-of-life (EOL) status on 2014-01-14. Fedora 18 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
