Dear Giovanni  and all

I am also struggling to get LabCA to compile under Windows, and I found

this thread from the summer.

Did you mange to get LabCA to work/compile with MINGW under windows 10?

Any hints on how to get this working are most welcome, I am normally

using EPICS/Matlab under Linux but in this case I am stuck with windows,

and would very much like a Matlab / EPICS integration.

Best

Bo

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.

Hello,

I would like to have some help.

I am trying to install LabCA 3.8.1 with MATLAB 2023 in Windows10.

I have set my path in the RELEASE as

BASE_SUBDIR=/base/

EPICS_BASE=/c/msys64/home/Gio-Ufficio/base-7.0.7

MATLABDIR = /c/MATlink

(MATlink is a symbolic link to the installation directory: C:\Program
Files\MATLAB\R2023a)

MATLIB_SUBDIR = win64/mingw64

(I also tried win64/microsoft)

When I run make (through MSYS2 MINGW64 ) I get the following error:

$ make

Any idea on what is the problem?
