Re: LabCA for MATLAB Installation error

[Straumann Till Sascha via Tech-talk <tech-talk at aps.anl.gov>]

Hi Giovanni.

I don't have a matlab license for windows, so I can't test this ATM.

You could try to simply delete and comment the

  typedef int pid_t;

and the following lines where 'getpid()'  is defined and _getpid declared.

I probably introduced these hacks a long time ago when windows didn't
declare these items yet.

Maybe Jim (on bcc) has additional recommendations - he has a lot of
experience with labca under windows.
