Mar 9, 2016 · Open CASCADE Technology 7.0.0.rc can be built using MinGW-w64 on Windows platform. MinGW is a minimalistic development environment for developing native Windows applications based on GCC. Project MinGW-w64 is its fork aimed to support 64-bit target and new APIs.
It's not kept as up-to-date as the mingw-w64 gcc available from the package manager in msys2. GCC 10 vs GCC 12
Apr 22, 2016 · MSVC is doing the compilation job significantly faster than MinGW-w64. The DLL sizes are comparable, if optimization is set to "-O2" for MinGW-w64, with "-O3" the DLLs from MinGW-w64 are larger. Binary files compiled with MinGW-w64 are performing significantly better than those compiled with MSVC.
For mingw, you want to download and install MSYS2. Using the builtin terminal, search for gcc pacman -Ss gcc. You can install gcc for "mingw32", "mingw64", or "ucrt64"; I always use "ucrt64" pacman -S ucrt64/mingw-w64-ucrt-x86_64-gcc.
We have the MinGW-W64 that is a fork of MinGW that supports those features and I was wondering, which one to use? Knowing that GCC is one of the most used C++ compilers. Or it's better to use the MSVC (VC++) on Windows and GCC on Linux and use CMake to handle with the independent compiler?
The problem is that aligned allocations need to be freed by regular free. So the free would need to learn to distinguish regular (non-aligned) vs aligned allocations and act accordingly. The solution is to use Microsoft specific non-pirtable aligned alloc and aligned free functions.
