4.4.2-3 unusable for 64bit development

[Steffen Neumann]

Binary package hint: gcc-mingw32

Hi,

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

Yours,
Steffen

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.

Hello,

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.

[Nathan Osman (george-edison55)]

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

in sid all ok, so i just get package from there.
http://packages.debian.org/en/sid/i386/gcc-mingw32/

[mapron (mapron)]

my fail.. please, ignore my comment - in debian the're missed too

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!

[Pali (pali)]

I moved all win32 cross compiler to new ppa:
https://launchpad.net/~mingw-packages/+archive/ppa

Official mingw-w64 ppa:
https://launchpad.net/~mingw-w64/+archive/ppa

Cross compiler(s) are in packages:
i686-w64-mingw32-toolchain
x86-64-w64-mingw32-toolchain

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

[Matpen (matpen)]

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...

[Pali (pali)]

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):
http://ppa.launchpad.net/mingw-packages/ppa/ubuntu/pool/main/w/w64-toolchain/

In my PPA pali/pali I have old version.

[Matpen (matpen)]

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!!

[Pali (pali)]

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

[Matpen (matpen)]

Thank you again!

I summarized the whole install process on ubuntuforums, in reply to others who were looking for the same answers:

[Stephen Kitt (steve-sk2)]

The gcc-mingw-w64 package, now available in Oneiric, supports 32- and 64-bit Windows development.

[Stephen Kitt (steve-sk2)]

gcc-mingw-w64 now replaces gcc-mingw32, please use that instead.
