Bug Description

Binary package hint: gcc-mingw32


the current version is unusable for 64bit development,
the debian version 4.4.2-5 has some missing files.

I confirm. Using the Debian version, a short test program (a simple main function doing nothing) could actually be compiled. In contrary to the current Ubuntu package, it has got 64-bit libgcc and other missing files, although a 64-bit g++ compiler isn't there.

I repack debian version of gcc-mingw32 to my PPA https://launchpad.net/~pali.rohar/+archive/ppa
I enabled support for amd64-mingw32msvc-g++ C++ compiler too (which is not in debian)

Copying my comments from bug # 640181.

gcc-mingw32 contains /usr/lib/gcc/i586-mingw32msvc/4.4.2/libgcc.a for the creation of 32-bit Windows (i586) code but the same does not exist (along with a bunch of other lib*.a files) for the amd64 target.

gcc-mingw32 for Maverick (10.10) on amd64 and i386 contains /usr/lib/gcc/amd64-mingw32msvc/4.4.4/libgcc.a as of 2010-09-19. Is there any way the changes needed could be incorporated into gcc-mingw32 for Lucid (10.04)?

I just discovered this when I tried to compile a C++ application with g++ - only to discover that g++ was missing. This is very serious and prevents any kind of development targetting Win64.

For those interested (and using the amd64 architecture), you can pick up one of the missing files here (g++): http://files.quickmediasolutions.com/amd64-mingw32msvc-g++.tar.bz2

After installing the mingw-w64 package on maverick amd64

matteo@ubuntubox:/tmp/qt-win-64$ amd64-mingw32msvc-g++ main.cpp -o test.exe
amd64-mingw32msvc-g++: command not found
matteo@ubuntubox:/tmp/qt-win-64$ amd64-mingw32msvc-gcc main.cpp -o test.exe
amd64-mingw32msvc-gcc: main.cpp: C++ compiler not installed on this system

while trying to use pali's ppa, I found out that the link is broken. I also tryed ppa:mingw-packages/ppa, but the packages there are still affected by the same bug.

Could someone explain a solution in detail (if there is one)?
Thank you!

I moved all win32 cross compiler to new ppa:

Official mingw-w64 ppa:

Cross compiler(s) are in packages:

and programs are:
$ i686-w64-mingw32-gcc
$ i686-w64-mingw32-g++
$ x86_64-w64-mingw32-gcc
$ x86_64-w64-mingw32-g++

It did not work:

sudo add-apt repository ppa:<ppa-name>
sudo apt-get update
sudo apt-get install i686-w64-mingw32-toolchain x86-64-w64-mingw32-toolchain gcc-mingw32 w64-toolchain mingw-w64

where <ppa-name> is one of (I tryed them all): pali/pali, pali/ppa, mingw-w64/ppa, mingw-packages/ppa

some packages are not found, for the others no newer version is available (I am on maverick 64bit). I even tryed to apt-get purge mingw-w64 gcc-mingw32, but the installed version is always the same.

the needed programs are, after all this, still missing on my system: i686-w64-mingw32-gcc, i686-w64-mingw32-g++, x86_64-64-mingw32-gcc, x86_64-w64-mingw32-g++, amd64-mingw32msvc-g++

Only one test worked:
wget https://launchpad.net/~pali/+archive/pali/+files/gcc-mingw32_4.4.2-6ubuntu0%7Elucid%7Epalippa5_amd64.deb
sudo apt-get install libmpfr1ldbl
sudo dpkg -i gcc-mingw32_4.4.2-6ubuntu0~lucid~palippa5_amd64.deb

The amd64-mingw32msvc-g++ compiler seems to work after that. This does not look like a clean solution, though.
I could really use a step-by-step explanation at this point...

Packges i686-w64-mingw32-toolchain and x86-64-w64-mingw32-toolchain are replecament for all mingw32 and mingw-w64 package. You need to purge all mingw packages before installing these news.

Here are working deb packages (it is not only for karmic):

In my PPA pali/pali I have old version.

Matpen (matpen) wrote :

ok, great! those two seem to work.

One last question: is there a way to grab them via apt? As said before, the following does not work:
sudo add-apt repository ppa:mingw-packages/ppa
sudo apt-get update
sudo apt-get install i686-w64-mingw32-toolchain x86-64-w64-mingw32-toolchain

Many thanks for your help!!

In ppa mingw-packages are packages builded only for karmic.
