Hello Jong Woo.

Are you sure you have set MATLABDIR in your RELEASE file correctly?

I notice that besides the compiler not finding 'mex.h' the following
error is printed:

> make[2]: /usr/local/MATLAB/2020b//bin/mexext: Command not found

Here at PSI I define

MATLABDIR = /afs/psi.ch/sys/psi.x86_64_el7/Programming/matlab/2020b/

and experience no errors.


Also:

ls /afs/psi.ch/sys/psi.x86_64_el7/Programming/matlab/2020b/bin/mexext

/afs/psi.ch/sys/psi.x86_64_el7/Programming/matlab/2020b/bin/mexext

and

ls
/afs/psi.ch/sys/psi.x86_64_el7/Programming/matlab/2020b/extern/include/mex.h
/afs/psi.ch/sys/psi.x86_64_el7/Programming/matlab/2020b/extern/include/mex.h

you seem to have a problem either with your MATLABDIR definition or your
matlab installation (which includes the possibility that you lack
permission to read these files).
