Differences between Mingw-w64 and TDM-GCC for a simple GDI project

Question

I need to build a simple non-commercial tool (dealing with Windows GDI API) on Win64 for Win64 (no cross compilation). MinGW seems the best option for me.
I have already used the 32 bit version in the past, as for 64-bit, can you tell me the main differences between the following builds?:

1. Mingw-w64
2. TDM-GCC

Besides the classic MinGW32 used a straightforward tool, mingw-get.exe, to customise the setup and keep up with the updating cycle. Which is the equivalent now?

Use the mingw-builds implementation of Mingw-w64. They maintain the package and have improved on the original Mingw-w64. Also check out MSYS2 -- it is sweet! You can use their pacman package manager to download and install the ming32 and mingw64 bit builds, along with a bunch of other software like Qt, git, subversion, etc... – Fermanagh

There are even more toolchains (e.g. clang) that can be used as alternative to MSVC++ ... – Quadrille

Answer 1

I've posted a short overview of MinGW / MinGW-w64 / TDM-GCC here: What is the difference between Orwell's MinGW and TDM Dev-C++ versions?

Which is the equivalent now?

It seems, there's no MinGW-W64 version of mingw-get; not sure if this is still valid. However, MinGW-w64 contains a nice installer.

Btw. MinGW-w64 is not just a "64 Bit port of MinGW" - it's more.

Sorry but in your previous post you say "My recommendation: Use the 3rd alternative: MinGW-w64 instead", but don't say why you suggest this. What is in MinGW-w64 not in TDM-GCC and vice versa? – Octangle

TDM uses the MinGW(-w64) runtime apis and is more a combination of gcc tools and mingw(-w64). MinGW-W64 as a good documentation and is very active. It also contributes lots of nice other stuff like pthread port for windows. The chance that a project supports MingGW is higher than TDM i think. – Podiatry

Answer 2

This is a late answer, but I have this same question and I was looking for by many hours and this is what I found...

I think that this link can to expand our view of the differences that include every distro, although the recommendation summary is based in their UI framework library (Qt 5)...

I'd suggest that you don't simply paste links (as links can break in the future), but expand on your answer here and have the links as a backup. – Homogeneity
