1) Download the current Mingw
and MSYS

1.5) I also downloaded the MinGW Runtime thingy's. Don't know if they are nessesary, but they won't hurt.

2) I made a folder called GNU and installed MinGW in c:\GNU\MinGW

2.5) I extracted the new runtime stuff and just overwrote what has there

3) I installed MSYS in c:\GNU\msys

Now you get an icon on the desktop where you can start the MinSys. Do this, because is creates your home folder. Then exit it again.

4) Download gmp and place it in your newly created home folder. (For me is was called C:\GNU\msys\1.0\home\Jes )

5) Start the MinSys up again from the desktop and type

gunzip gmp-4.1.4.tar.gz
tar -xvf gmp-4.1.4.tar
cd gmp-4.1.4
make install

Then GMP installs (takes about two or three cups of cofee ).

6) Afterwards, download ECM-GMP 6 from and place the file in your home folder.

7) In the "home" directory (type cd ~ RETURN to get there) type
gunzip ecm-6.0.tar.gz
tar -xvf ecm-6.0.tar
cd ecm-6.0
./configure --with-gmp=/usr/local

8) Look and behold! 4 executables have appeared, and the one to look out for is ecm.exe

Have fun
