good find but this isn't my job I spent too much lifetime in the well working fltk-c wrapper

PlutoVG for FreeBASIC is complete now. (see first post)
I build 32/64-bit static/dynamic Windows/Linux libs.

In ded a nice collection !

I compiled the PlutoVG 2D vector drawing library works perfect with FreeBASIC

PlutoVG is a komplete standalone 2D vector graphics C library. https://github.com/sammycage/plutovg https://shiny3d.de/public/libs/smiley.png download: libplutovg.zip from Nov 09, 2022 Included are 32/64-bit static and dýnamic libs for Windows and Linux. I prefer static linking for FreeBASIC but you...

if you have a windows box here are the Windows 32/64-bit fltk 3.5 runtimes.
download FLTK-headers-and-runtime-windows.zip

compile in the bin folders:
bin32/win32test01.bas
bin64/win64test01.bas

Win32 win.show() crashed with memory access at address 0x00000000 ! Both win -gen gas and -gen gcc no stacktrace with GDB the binary release are not compiled with "-g" :-( I have hand counted struct/class member offsets in the fltk-c fltk-c++ wrapper ! and type "dent" differs on ...

@angros47 I got your tiny window / button test working on Windows 64-bit but if you do more real stuff you have many open forward references ! If you try to fix it include all files and work from one to the next ! try this: extern "c++" #include once "Fl_Device.bi" #include once ...

I uploaded a new version see first post.

All OpenGL Extensions are supported from OpenGL V1.0 - V4.4 (round about 400 extensions)
~2300 OpenGL commds are dynamic loaded bei the extension wrangler.

New upload I found and fixed a bug (quaternion single and double) see first post.

I uploaded my AntTweakBar package for FreeBASIC see first post.

Included are tests 32/64-bit for FreeBASIC fbgfx OpenGL, freeGLUT and GLFW

Only as Info with FBTrueType you can print wstring in any language with FreeBASIC also.
