Failed to compile the FOX Toolkit

[ghost]

The FOX Toolkit's homepage is still on insecure http connection, so I created a mirror on Github for you to get the source easier:

I'm compiling on MINGW64. This is the error message:

(I'm building from the build directory to keep the source tree clean).

Something is wrong with MINGW64? VOID should be defined, please see:

https://learn.microsoft.com/en-us/windows/win32/winprog/windows-data-types

(VOID is just an alias of void).

How to compile it? What are the required dependencies? I got this

../../lib/FXGLContext.cpp:605:29: error: 'XftFont' was not declared in this scope
  605 | static FXbool glXUseXftFont(XftFont* font,int first,int count,int listBase){
      |                             ^~~~~~~

It's straight forward on the MINGW64 Shell. Run the configure script and then make -j8.

I still get same compiler error as above.

Now I get the following error. Was that project even compiled with mingw before?

../lib/FXThread.cpp:334:12: error: 'frequency' was not declared in this scope
  334 |   FXASSERT(frequency<FXLONG(9223372036));       // Overflow possible if CPU speed exceeds 9.2GHz
      |            ^~~~~~~~~

It did build fine on MinGW before. Please try this: https://github.com/iahung/fox-cmake

The following patch will fix the mingw headers issue.

diff --git a/include/xincs.h b/include/xincs.h

Even after that, I got the following error.
