CDO

Hi Ralf,

thanks for the excellent work concerning the cross-compilation of CDO for Windows-Platforms.

I was also able to build the Win32-version of CDO on our hardware. Attached I describe everything I did. Perhaps this can be helpful for others:

As suggested I used an ubuntu-9.10 in a virtual-box.

These packages can be found here:

• The “VirtualBox”-virtualizer: http://www.virtualbox.org/
• The VirtualBox-Ubuntu-9.10-Image:

(overview: http://virtualboxes.org/images/ubuntu/ )

(direct download link: http://downloads.sourceforge.net/virtualboximage/ubuntu-9.10.vdi.7z )

Before starting the cross-compilation in this environment, it is necessary to install two additional packages:

• sudo apt-get install mingw32
• sudo apt-get install wine

mingw32 is the cross-compiler package itself;
wine is used to execute some tests during the “configure”-step of the hdf5-library.

The following steps are based on the packages “libs4cdo-0.0.5.tar.gz” and “cdo-1.4.3.tar.gz“ as provided on the CDO-homepage.

mkdir =/home/ubuntu/cdo_win
export WORK_DIR=/home/ubuntu/cdo_win
cd $WORK_DIR
tar xzvf libs4cdo-0.0.5.tar.gz
cd libs4cdo-0.0.5
make win32libs4cdo PREFIX=$WORK_DIR
cd ..

tar xzvf cdo-1.4.3.tar.gz
cd cdo-1.4.3
./configure --host=i586-mingw32msvc --prefix=$WORK_DIR --with-netcdf=$WORK_DIR --with-proj=$WORK_DIR --with-zlib=$WORK_DIR --with-szlib=$WORK_DIR --with-hdf5=$WORK_DIR --with-threads=$WORK_DIR
make
make install

The cdo-executable will then be available in $WORK_DIR/bin

Best regards,
