[Mingw-w64-public] Standard library installation paths?

[Václav Š. <eu...@do...>]

Greetings to experienced Mingw64-ers,

I am currently compiling several 3rd-party libraries which I need for my 
code. Among those are glib, VTK, Qt and perhaps several others. I have 
the (32bit) MSYS installed, which provides standard directories like 
/usr/lib, /usr/include, ...

When configuring libs, I use --prefix=/c/MinGW64 to not to install them 
into the 32bit MSYS tree, but I fear that I will have comflicts between 
32bit/64bit headers, as the 32bit ones are in the default search path. 
Secondly, it is a bit tedious to install everything to non-default 
paths. Is there some solution to this I am overseeing?

Second thing which comes to my mind: are there perhaps some pre-built 
packages for common libraries? How about the cross-packages from Fedora, 
couldn't they be just unpacked and used?

Thirdly: MSYS's make hangs sometimes when doing parallel compilations 
(of VTK); is that a know issue? Would I be better off compiling 64bit 
gmake binary?

Cheers, Václav
