Update glib and glibmm by lluixhi · Pull Request #453 · mxe/mxe (original) (raw)
OK, I tried to build glib on i686-pc-mingw32.shared, and it failed. The problem is that MinGW does not provide a prototype for rand_s() (see http://sourceforge.net/p/mingw/bugs/2122/). However mingw-w64 does.
This bug is fairly hard to fix, because all three options seem rather unrealistic:
- Patch mingwrt using a variant of http://sourceforge.net/p/mingw/bugs/2122/attachment/rand_s-mingw.patch
The patch only applies to mingwrt 4.*, applying it on 3.20 (which mxe uses) is possible but rather difficult because currently mxe simply gets the binary and installs it. Patching means getting the source and build it, and all sorts of chicken vs. egg problem appears. - Disable glib on i686-pc-mingw32.
glib is crucial to many projects:

3. Remove i686-pc-mingw32.
There are still packages that can only be built with MinGW, and removing this target isn't very nice.
So, I propose that we either figure out a way to make MinGW use the old version while mingw-w64 the new one, or to delay this update. @tonytheodore?
