TDM-GCC 4.2.3 for MinGW

(1/4) > >>

TDragon:
With GCC 4.2.3 now released, I've created the usual TDM binary distribution for MinGW. As always, binary packages are available as drop-in replacements for the MinGW project's official gcc packages.

I haven't deviated from my standard build process in creating this release, so I don't expect any problems. I always test every release to ensure that it can successfully build the latest version of wxWidgets and Code::Blocks SVN -- however, I haven't yet done so for this release because the majority of my CPU is currently occupied in a different build process. As soon as that's finished, I'll finish testing and confirm that everything works as expected.
Update:
Yes, C::B SVN and wxWidgets work fine with this release.

Full details are at http://www.tdragon.net/recentgcc/ .

Disclaimer:
You should only use this build if you need the features or bugfixes done since GCC 4.2.1. If you don't need them or aren't sure, you should instead use the official MinGW GCC 4.2.1 Technology Preview, or (most preferably) the official MinGW GCC 3.4.5 stable release.

Cheers,
John E. / TDM

I am getting an error compiling an sample from wxWidgets trunk.

I was able to compile the sample using MinGW's GCC 3.4.5 and 4.2.1

Here is the error.

lemd:
Is it can be worked on Windows XP?

TDragon:
Nope, Windows 3.1 only, sorry...

...Why wouldn't it work on XP? I can understand if you wanted to know whether it worked on Vista (it does).

thomas:
By the way, TD... I tried your 4.3.0 build too, very much appreciated (because I'm too stupid to build myself, for some reason it never works).

Unluckily, it seems like the GCC team still has to do some serious overhauling on the optimizer before 4.3.0 becomes usable. I had it move code which wasn't invariant and which was marked __volatile__ out of a loop. To make matters worse, the exit condition depended on that code (resulting in an infinite loop). So basically, that makes 4.3.0 unusable.
