Compiling FPCamera.c with gcc produces the following output (with -wall):

I managed to get a hello world raylib+imgui program working on Linux.

When I got to the Mac, it compiled without errors, but when running it failed to render the imgui part. Rendering with raylib works. And I know the imgui part is working, because I blindly clicked around where the button was supposed to be, and eventually it reacted (a print on stdout).

I'm new to both imgui and raylib, can you help me debug this one?

FontDataOwnedByAtlas has to be set to false to void imgui trying to free the static font data

ImGui::DestroyContext() is never called inside rlImGui, but ImGui::CreateContext() is, so I figured it should be called aswell

I added mouse Cursor support

its inspired/based by/on the win32 backend from Dear ImGui

it implements all cursors (I think)

Changes

I changed the original part that hid and unhid the cursor and made it only change it if the cursor is changed (or ImGui draws the cursor itself)

• root script had a typo for TPOrbitCameraCSample folder. No more missing raylib.h.
• Premake/Game script had wrong file/ directories
• Premake/raylib scripts had wrong file/ directories

• Root premake creates a solution but has CloseWindow already defined ERROR.

the scissorTest I removes seems to have no purpose, it also messes with everything that is done before its disabled again

saw randomly that there was a IO ref created where one already is available, so I removed it
