ISSM_DIR not found when launching matlab and running startup

[deleted]

Warning: Executing startup failed in matlabrc.

This indicates a potentially serious problem in your MATLAB setup,

which should be resolved as soon as possible. Error detected was:

'ISSM_DIR' environment variable is empty! You should define ISSM_DIR in your .cshrc or .bashrc!

For GUI applications, there is no real way of letting MacOSX know about the ISSM_DIR environment variables. So if you are not

launching matlab from command line, but by clicking the Matlab icon, you will have to edit your startup.m (found in ISSM_DIR) and hardcode your path

to ISSM as follows:

% clear the last warning to focus on the warnings of the ISSM path


lastwarn('');
ISSM_DIR='/Users/username/yourpathtoissm';
if (isempty(ISSM_DIR)),
        error('''ISSM_DIR'' environment variable is empty! You should define ISSM_DIR in your .cshrc or .bashrc!');

end

don't forget to replace username and yourpathtoissm accordingly.

After following your instructions, I am able to source the startup.m file without a glitch. However, as soon as I try and run test101,

I get:

>> test101

Error using issmdir (line 17)

issmdir error message: 'ISSM_DIR' environment variable is empty! You should define ISSM_DIR in your .cshrc or .bashrc!

Error in ismumps (line 7)

configfile=; %should find it in the install target

Error in solver/setdefaultparameters (line 40)

if ismumps(),

Error in solver (line 15)

obj=setdefaultparameters(obj);

Error in model/setdefaultparameters (line 1064)

md.solver = solver();

Error in model (line 97)

md=setdefaultparameters(md);

Error in test101 (line 1)

md=triangle(model(),'../Exp/Square.exp',50000.);

What should I do?

you will have to do something similar also on the ISSM_DIR/src/m/os/issmdir.m routine.

edit it and modify as follows:

function ISSM_DIR=issmdir()

%ISSMDIR - Get ISSM_DIR environment variable

% Usage:

% ISSM_DIR=issmdir()

ISSM_DIR='/Users/username/issmdir';

if (isempty(ISSM_DIR)),

error('issmdir error message: ''ISSM_DIR'' environment variable is empty! You should define ISSM_DIR in your .cshrc or .bashrc!');

end

same thing, don't forget to replace username and issmdir accordingly.
