only 4 of these warnings are still relevant, CMake shall be used to disable them
Compiler definitions:
NOMINMAX:
* is already globally defined in SetGlobalCompilerAndLinkerSettings.cmake
WIN32_LEAN_AND_MEAN:
* use CMake target_compile_options on relevant targets
Warnings that still occur:
C4251, C4273, C4275: all related to dllimport / export
* use CMake target_compile_options on relevant targets
C4661: no suitable definition provied for explicit template instantiation request
* triggered in Mesh because of Vector3D in Base - not all functions are defined in header
* use CMake target_compile_options on relevant targets
Warnings that are Currently not triggered (fix code if they appear again):
C4005: macro redefinition
C4244: argument conversion, possible loss of data
C4267: conversion from size_t to type, possible loss of data
C4305: truncation from type1 to type2
* only occurrence disabled in Reader.cpp
C4522: multiple assignment operator specified
C5208: unnamed class in typedef name
Obsolete Compiler warnings:
C4181: not mentioned in Microsoft docs anymore
C4290: C++ exception specification ignored except to indicate a function is not __declspec(nothrow)
* throw(optional_type_list) deprecated in C++17
C4482: nonstandard extension used: enum 'enumeration' used in qualified name
* not generated for compilers that support C++11
C4503: 'identifier': decorated name length exceeded, name was truncated
* obsolete since Visual Studio 2017
C4786: not mentioned in Microsoft docs anymore
Previously the code defined compatiblity usings in `QtOpenGL.h` header,
which I think was added for backwards compatiblity with previous Qt
OpenGL widgets.
As far as I can tell, this is not necessary anymore, and can be cleaned
up.
(found while searching for the build error on armhf/armel on Debian
buildds, once resolved will make an additional PR for that.)
$grep -r GL_MULTISAMPLE src/
yields:
src/Mod/Sandbox/Gui/Overlay.cpp: #ifndef GL_MULTISAMPLE
src/Mod/Sandbox/Gui/Overlay.cpp: #define GL_MULTISAMPLE 0x809D
src/Mod/Sandbox/Gui/GLGraphicsView.cpp:#ifndef GL_MULTISAMPLE
src/Mod/Sandbox/Gui/GLGraphicsView.cpp:#define GL_MULTISAMPLE 0x809D
-> The defines are defined, but never used in the compilation unit
