Cannot compile for Windows using mingw64 on Fedora 26

[JasonatCU]

I'm trying to compile the .exe's for Windows using Fedora as mentioned in the Install.md. I ran the qa/admin/check-vm to get the dependencies required for build, though I am missing a few that I'll list below. When I run "./Makepkgs --verbose --target mingw64" from a fresh Fedora 26 VM, I get lots of warnings, then finally an error ending with "fatal error: sys/wait.h: No such file or directory." This is included from exec.c. I tried removing the include out of curiosity from exec.c and as expected I got more errors than I could deal with. Any suggestions? I am new to the open source scene, so please bear with me while I learn this. Thanks for your help.

Edit**

Also forgot to mention, that I installed these packages as well, as mentioned in the Install.md file. mingw64-qt5-qttools-tools mingw64-qt5-qtbase-devel mingw64-pkg-config mingw64-readline mingw64-xz-libs

Edit Just wanted to note, if I run "./Makepkgs --verbose" without specifying the target mingw64, then it compiles the rpms without issue at all.

@JasonatCU ... I suspect it is a very long time since anyone tried to compile PCP for Windows ... there are a number of warnings that need to be fixed before we get the fatal issue ... since I broke the latter I'll fix that and clean up anything else that is obvious bit-rot since PCP was last built for Windows.

[natoscott]

@kenj the warnings have been around forever - most recent build was a month or so ago, so I think we should be building OK again with those pmProcessExec/Pipe updates.

build: small fixes for the Windows build, and use Qt5

[kmcdonell]

@natoscott the warnings are not all benign it appears to me ... I'll try to fix some of 'em on the way to sorting out what to do in exec.c

[JasonatCU]

Thanks guys! I look forward to trying this on Windows. If I can help in any way, I will give it my best shot.

[kmcdonell]

@JasonatCU when commit 4bdf563 makes it from my tree into the official tree, you should see Makepkgs run to completion for your cross-compilation. @natoscott is there a recipe for installing and testing on a Windows platform, now that we no longer build installable packages for Windows?

[natoscott]

@kmcdonell there is no recipe. Its definitely an area where work is needed - individual commands can be run by setting %PATH to add libpcp (and friends) though.
