Hi,

could we introduce something in the configure.sh script for the external packages to do a make -jN for building the external packages? It would be sooo much faster on my quad-core...

Cheers, Christian

Hi Christian

If you look into the scripts you can see that this is already done in most of the cases. For some packages we encounter problems using parallel build, so for this packages we don't use this feature.
We check how many cores are available and use this number for make -j .
If you want to set a different number please set a environment variable which is checked by the script.

export NCPU=<your number>

Ciao

Florian
