Re: How do you install the gtk 3 development libraries and toolchain on Windows 64bit?

[Simon]

Hello vonH.

First download and install msys2.

[https://msys2.github.io](https://msys2.github.io)

Then open the msys shell and execute 


 pacman -Ss gtk3


in response to get the list of packages

mingw-w64-i686-gtk3 - for x32

mingw-w64-x86_64-gtk3 - for x64


 pacman -S mingw-w64-x86_64-gtk3


In the latest version of msys2 something is broken and the packages are not 
installed correctly.

Pacman downloads packages to C:\msys64\var\cache\pacman\pkg and then outputs 
"error: failed to commit transaction".

I can only offer you a dirty hack 


 pacman -S mingw-w64-x86_64-gtk3 --force


Don't forget to add C:\msys64\mingw64\bin (and \lib) in the path variable.

About nim-chess. In gtk3.nim and gdk3.nim 


libgtk-win32-3.0-0.dll
libgdk-win32-3.0-0.dll


to replace 


libgtk-3-0.dll
libgdk-3-0.dll

and additionally execute 


ln -s ~/ngtk3/nim-cairo/src/cairo_pragma.nim

and then chess works.

First of all thank you for your help. Now to answer your questions.

> I assume that you are using an 32 bit Nim installation?

Yes, but before that I used 64 bit. Differences invisible.

> Is the chess game running for you?

Yes, a couple of fixes and it worked. If you want I'll write more detailed.

Windows 7 x64, gtk3 (3.20). Installed with Msys2.


 glib except int32

NEd compiled. But is not completely working. I'll try to fix it. Anyway, thank 
you again.

Re: GTK 3.20 Nim wrapper

Now the problem with NEd:


.nim(1796, 14) template/generic instantiation from here
c:\nim\lib\system\threads.nim(396, 41) Error: type mismatch: got (int)
but expected one of:
proc int32(value: GVariant): int32

Re: GTK 3.20 Nim wrapper

[Simon]

I get an error when trying to compile 


board.nim(70, 26) Error: ambiguous call; both gtk3.window(obj: expr) and 
gdk3.window(object: expr) match for: (Widget)


How to fix it?
