"Professional CMake" book suggest the following:
"Targets should build successfully with or without compiler support for precompiled headers. It
should be considered an optimization, not a requirement. In particular, do not explicitly include a
precompile header (e.g. stdafx.h) in the source code, let CMake force-include an automatically
generated precompile header on the compiler command line instead. This is more portable across
the major compilers and is likely to be easier to maintain. It will also avoid warnings being
generated from certain code checking tools like iwyu (include what you use)."
Therefore, removed the "#include <PreCompiled.h>" from sources, also
there is no need for the "#ifdef _PreComp_" anymore
The Python version of this class is entirely static: no instance is
required. Internally it accesses th pre-constructed instance of the C++
ApplicationDirectories class that is instantiated at program startup by
the Application class.
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
Use std::filesystem wherever possible, replacing most uses of
std::string when the object is actually a path. This is the first stage
of refactoring, and does not make any changes to Application that affect
client code. Access to the new directory-handling class is implemented,
but is unused by any external code.
Within code often it is required to temporarly override value of some
object properties. To properly restore old values they must be stored
somewhere and the developer must remember to manualy restore them.
This commit introduces utilities that can be used to make it easier
using RAII idiom to guard the overrides.
Every basic data type is stored in Base module, color is standing out as
one that does not. Moving it to Base opens possibilities to integrate it
better with the rest of FreeCAD.
* Add safe-mode which starts freecad in a clean environment
* Integrate safe-mode
* Show "(Safe Mode)" in main window title
* Show safe mode info when safe mode is started
* Created Safe Mode Icon
* Use new icon
* Add PreCompiled.h
* Add exports for windows
