Comment 10 for bug 568028

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...
