32-bit builds not working for RPi4

[dragon99919]

Hey! I just tried to compile both of FE and SE on my RPi4 (vanilla Raspberry PI OS 32-bit) and I get these errors.

For FE:

/home/dragon99919/git/SeriousSamClassic-VK/SamTFE/Sources/Engine/Graphics/Gfx_wrapper.cpp: In function ‘void GFX_SetFunctionPointers(INDEX)’:

/home/dragon99919/git/SeriousSamClassic-VK/SamTFE/Sources/Engine/Graphics/Gfx_wrapper.cpp:940:31: error: invalid conversion from ‘void ()(INDEX, INDEX)’ {aka ‘void ()(int, int)’} to ‘void ()(INDEX, short unsigned int)’ {aka ‘void ()(int, short unsigned int)’} [-fpermissive] 940	gfxDrawElements = &svk_DrawElements;	^~~~~
void ()(INDEX, INDEX) {aka void ()(int, int)}

make[2]: *** [CMakeFiles/Engine.dir/build.make:1389: CMakeFiles/Engine.dir/Engine/Graphics/Gfx_wrapper.cpp.o] Error 1

and for SE the test program doesn't even wanna budge:

Will build with 'make -j4' ... please edit this script if incorrect.

  is not able to compile a simple test program.

  It fails with the following output:

  CMake will not be able to correctly generate this project. Call Stack (most recent call first): CMakeLists.txt:2 (project)

-- Configuring incomplete, errors occurred!

Any ideas what can I do about these?

• -- Check for working C compiler: /usr/bin/cc - broken CMake Error at /usr/share/cmake-3.18/Modules/CMakeTestCCompiler.cmake:66 (message): The C compiler "/usr/bin/cc" is not able to compile a simple test program.

• cc: error: unrecognized command-line option ‘-m32’; did you mean ‘-mbe32’?

and

• DUSE_I386_NASM_ASM=TRUE

I think the problem is this. It is not logical to use assembler from another architecture. Try this command:

cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo -DCMAKE_C_FLAGS=-mbe32 -DCMAKE_CXX_FLAGS=-mbe32 -DUSE_I386_NASM_ASM=FALSE .. -DRPI4=TRUE

Okay, so while the initial error for SE doesn't occur now, the compiler throws itself out of the window in the same place as in case of FE:

Change in

Sources/Engine/Graphics/Gfx_wrapper_Vulkan.cpp static void svk_DrawElements(INDEX ctElem, INDEX *pidx)

to

static void svk_DrawElements(INDEX ctElem, INDEX_T *pidx)

Cool, both builds are working now after this last fix, thx!
