1. HELP RayGui DLL

Hello all,

I am trying to get Raygui built into DLL, but I keep coming up short. I've both the GCC and MSVC methods of trying to compile and build it (https://github.com/raysan5/raygui), but I keep coming up with errors. I even tried building Raylib 5 using the makefile which includes RayGUI (as long as you set the option to true, from false) (https://github.com/raysan5/raylib/blob/master/src/Makefile) and it still comes up with build errors. It seems to be linker errors, even though I only change the bare minimum required. If anyone can help that would be great.

I don't think I've ever tried building any of the raylib projects from source. Could you share some of the errors you're getting?

The building directions for raygui don't make any reference to raylib. So you're probably getting errors trying to find any of the raylib functions.

I think they're assuming you're linking raylib statically but then building raygui as a DLL? That seems weird and makes the directions incomplete.

The steps below worked for me. I had to add some options to the gcc command so it could link to raylib.dll in the other source directory.

Build raylib.dll from source 

git clone https://github.com/raysan5/raylib raysan5\raylib 
cd raysan5\raylib\src 
mingw32-make PLATFORM=PLATFORM_DESKTOP RAYLIB_LIBTYPE=SHARED

Build raygui.dll from source 

git clone https://github.com/raysan5/raygui raysan5\raygui 
cd raysan5\raygui\src 
copy raygui.h raygui.c 
gcc -shared -o raygui.dll raygui.c -I../../raylib/src -L../../raylib/src -DRAYGUI_IMPLEMENTATION -DBUILD_LIBTYPE_SHARED -static-libgcc -lopengl32 -lgdi32 -lwinmm -lraylib -Wl,--out-implib,librayguidll.a

Thanks Greg. However I keep hitting this snag right here. I get the error ld returned exit 1 status raylib.dll.rc.data: file not recognized: file format not recognized

I found this: https://github.com/raysan5/raylib/discussions/2560 I tried the windres raylib.dll.rc -o raylib.dll.rc.data --target=pe-x86-64 but it comes up with the error Can't detect target endianness and architecture I'm using TDD-GCC-64 under Windows 11 Pro 64-bit. I'll try a few other things and see if I can get it working myself.

EDIT: Ok I got the first part done. I was able to build Raylib using the mingw32-make command. I had to do this, 

windres raylib.dll.rc -o raylib.dll.rc.data --target=pe-i386 
then 
mingw32-make PLATFORM=PLATFORM_DESKTOP RAYLIB_LIBTYPE=SHARED

When trying to build raygui DLL, I get this error 

gcc -shared -o raygui.dll raygui.c -I../../raylib/src -L../../raylib/src -DRAYGUI_IMPLEMENTATION -DBUILD_LIBTYPE_SHARED -static-libgcc -lopengl32 -lgdi32 -lwinmm -lraylib -Wl,--out-implib,librayguidll.a

Missing argument in parameter list. 
    + CategoryInfo          : ParserError: (:) [], ParentContainsErrorRecordException 
    + FullyQualifiedErrorId : MissingArgument

EDIT 2: Alright, I got it to work using this command. 

gcc -shared -o raygui.dll raygui.c -I../../raylib/src -L../../raylib/src -DRAYGUI_IMPLEMENTATION -DBUILD_LIBTYPE_SHARED -static-libgcc -lopengl32 -lgdi32 -lwinmm -lraylib
