GCC 4.4.0-tdm-1 for MinGW (with installer)

<< < (2/11) > >>

ollydbg:
I have the same problem like killerbot.

By the way, I haven't rebuilt the wxWidgets library with gcc 4.4.(I use the old library built with tdm-gcc 3.3, is it the problem?)

My original TDM-MinGW was in D:\mingw.
I just update this folder with the new 4.4.0 version.

It seems there is no such folder named "d:\crossdev\b4.4.0-tdm-1". in my system. :D

TDragon:
Apparently the one change I made between the version I used to build Code::Blocks and the release version affected more than I thought!

Until this is fixed, adding "-Wl,--exclude-libs,libgcc_eh.a" to the Other linker options for the "sdk" target will allow the build to succeed.

TDragon:
I've uploaded patched versions of the core, g++ and fortran packages, and this problem should be gone. As always, the TDM/MinGW installer should detect the upgrades automatically when you choose "Manage"; or, if downloading manually, be sure to get the new packages ending in "-2".

Also I uploaded a new version of the installer (1.905.0) that doesn't add the "bin" directory to the PATH environment variable if it's already there.

ollydbg:
Thanks for your effort!
I will download and test it now. :D

Edit:

build codeblocks successfully! Great!

thomas:
Thanks once again for the effort :)
Unluckily this build gives me internal compiler errors (segfault) which I'm unable to properly identify.

I've got a function declared __attribute__ (( __cold__ )) contained in a namespace, and it ICEs on a harmless for() loop. If I comment out the for() or remove either attribute or namespace, it compiles fine. If I copy and paste the function as-is into a "hello world" project, it works fine.
The 4.3 compiler has no problems with the same code.
