Oh, these errors are the best. 🔥

There's #define Complex in one of the X11 headers, which is the stupidest thing ever, but what can we do. It's being undef'd in Magnum headers that include X11 but I can't really prevent this from happening everywhere, unfortunately...

If you #undef Complex after including anything related to X11, EGL or GLX, that should make it work.

hmmm ok

[mgood7123]

if i include Magnum before my glis header (instead of after) i get even more errors...

and if i remove the header then i only get Magnum undeclared

[mgood7123]

hmmm it appears that i need to include Magnum before egl but after opengl32

#include <GLES3/gl32.h>
#include <Magnum/GL/Context.h>
#include <EGL/egl.h> // includes X11 headers on unix

[mosra]

Magnum provides its own GL headers, so you're getting a conflict with the system-wide one. I wasn't aware of there being a GLES3/gl32.h, just pushed a fix for that in 80a844c. Can you pull and try again?

Note that you should include Magnum GL headers before the system ones to avoid errors with missing definitions -- the system ones will never be as complete as Magnum needs, which is why it has its own.

[mgood7123]

a fix is to replace the egl and gl32 headers with Magnum/GL headers instead, and link with Magnum::GL and Magnum::EglContext

#include <Magnum/Platform/GLContext.h> // OpenGL
#include <Magnum/Platform/WindowlessEglApplication.h> // EGL
#include <Magnum/GL/Context.h> // OpenGL

set(WITH_GL ON CACHE BOOL "" FORCE)
set(TARGET_GLES ON CACHE BOOL "" FORCE)
set(WITH_EGLCONTEXT ON CACHE BOOL "" FORCE)
add_subdirectory(dependancies/magnum)
# ...
testBuilder_add_library(GLIS Magnum::Magnum)
testBuilder_add_library(GLIS Magnum::GL)
testBuilder_add_library(GLIS Magnum::EglContext)
