[photran] [Resolved] managed make from command line

[Daniel Harenberg <dan.harenberg@xxxxxxxxxxxxxx>]

Hi again,

in the end, David was right. The problem was that the executable is
created in the subdirectory /projectname/Release, while the directory to
write to was /projectname/model_output. This does work when clicking on
the run-button in Eclipse, since the project directory is /projectname,
but in the command line I was running the executable from
/projectname/Release. So I first had to create
/projectname/Release/model_output. Stupid me.

Thanks for the help!

Daniel
