I used this tutorial to export my auxiliary files into a different directory.
Basically i just add
Options -> Configure -> Commands and added the
build folder into
Options -> Configure -> Build -> Build Options -> Additional Search Paths -> Log.
This succesfully generates all the auxilliary files in the build folder and it's also possible to generate the pdf.
Unfortunately biber has a problem with this setup:
Prozess gestartet: biber.exe "MyFile"
INFO - This is Biber 1.7
INFO - Logfile is 'MyFile.blg'
ERROR - Cannot find control file 'MyFile.bcf'! - did you pass the "backend=biber" option to BibLaTeX?
INFO - ERRORS: 1
I guess i have to specify the correct path for biber somewhere in Texstudio. Does anyone know where i have to update the path?
