Compile orekit python wrapper on windows

Orekit Python Wrapper usage
1

Hi all, I tried to compile orekit python wrapper on windows.
After installing java (1.8), microsoft visual C ++, JCC (3.13), I ran the following command:

python -m jcc
–use_full_names
–python orekit
–version 12.dev0
–jar C:\Users\victo\Documents\orekit_install\orekit_python_artifacts-dev/orekit-12.0-SNAPSHOT.jar

And I had the following error :

Note that I performed the equivalent operation on a Linux machine and it worked.

Please, would you mind give me some suggestions?

Many thanks

Hi Victor,

Compling orekit can be a bit challenging (that’s why I recommend conda packaging that locks the dependencies).

I would suggest you start with the version that is currently being build for the conda version, the artifacts are at: GitHub - petrushy/orekit_python_artifacts: Primary jar's for python orekit and make sure that that one builds.

I have not yet tried to build the 12.0 development branch. If you from the generated source figure out which classes that are generating the error you can start with --excluding them as a first step in the investigation…

Regards
Petrus

Hi Victor,
I did this a few weeks ago, starting from this script in the conda recipe. I think I had the same error, and it came from missing --reserved keywords in the build command, maybe PASCAL or PERCENT.

Hi Clement,
It was that, I added – reserved PASCAL keyword in the build command and it worked.
Thanks for your help
Victor
