GCC 4.4.1-tdm-2 for MinGW (with installer)

(1/8) > >>

TDragon:
The second TDM-GCC release of GCC 4.4.1 is now available!

NOTICE:
The first TDM-GCC release of GCC 4.4.1 had a bug that caused a major slowdown in nearly any non-trivial program that it compiled. Be sure to upgrade to the new TDM-2 release if you're currently using 4.4.1-tdm-1.

The 4.4 series continues to take a bit longer to bring from vanilla release to TDM release, but in exchange I've fixed nearly all the outstanding bugs in the TDM-GCC tracker. This release re-enables support for large files, correct formatting of long doubles in iostreams, and more. For general changes in the GCC 4.4 series, see http://gcc.gnu.org/gcc-4.4/changes.html.

I tested this release by successfully building wxWidgets (2.8.10), and building and running Code::Blocks (SVN r5848), both without errors!

Binary packages are available for the Ada, C, C++, Fortran, Objective-C, and Objective-C++ languages, as drop-in replacements for the MinGW project's official gcc packages. Additionally, the TDM/MinGW installer will automatically install TDM-GCC and the MinGW compiler suite for you. Full details and download links are at http://www.tdragon.net/recentgcc/ .

Disclaimer:
The TDM-GCC builds are unofficial replacements for the official MinGW releases of GCC binaries. TDM-GCC was previously recommended for experimentation purposes only, but constant use in day-to-day development and a total download count of over 60,000 have proven the TDM-GCC releases to be at least as usable as the most recent official MinGW GCC release. (Please note that this does not mean that there are no bugs; merely that there is a different set of bugs with a similar or lesser average criticality.) Therefore, TDM-GCC is now heartily endorsed for production use in any non-critical environment, with only the following caveats:

* TDM-GCC is not formally affiliated with or endorsed by the MinGW project (although several MinGW team members make use of it)
* No level of support for TDM-GCC is in any way guaranteed (although a best effort is made to fix bugs as they are found or forward them to GCC Bugzilla)
Cheers,
John E. / TDM

The upgrade using your installer went very smooth; and everything seems to work well so far, including re-compiling Code::Blocks.
Thanks!

EDIT: Oops. This morning things do not look as rosy as they did last night. CB and wxWidgets (2.8.10) all seemed to compile with only minor warnings. But now when I load a project into Code:Blocks, CB goes to ~95% CPU usage and never stops. My Nightly CB version seems to work just fine using TDM 4.4.1, but it appears that I have screwed something up in the compilation process of Code:Blocks itself. Oh well!

EDIT 2: Well shoot. The more I experimented with even my Nightly CB version, the more problems I had. After re-compiling several of my existing projects with 4.4.1, they ran very slowly or not at all. I may have something wrong with my setup; but, after reverting to your TDM-GCC 4.4.0 (and recompiling everything), all seems to work fine.

TDragon:
Well, I'm not able to reproduce any of those problems. Really, there's only one change between the 4.4.0 r2 release and this one that affects code generation, and that one actually *fixes* floating point formatting by detecting and using the correct math library. I don't see how it could be causing these problems.

In C::B, have you tried systematically disabling plugins to find a specific problem area?

rhf:
Thanks, John.
It is very weird. I'll experiment with it some more after I get a little work done.

ollydbg:
Thanks John.
I will download this package and testing building OpenCV library then. :D
