Yes, I got it but didn't find the time to look into...
MortenMacFly:
OK, I see here:
--- Quote ---./R2010b/extern:
examples
include
lib
--- End quote ---
...the include folder should be [MATLAB]/extern/include, [MATLAB]/simulink/include, the library folder /extern/lib/glnxa64 and another one I am missing where all the link libraries are installed into. Most likely these have been put under /usr/local/lib/matlab or something like that... can you check that (it depends on the Linux platform unfortunately)? You can search for e.g. libmex* on your HDD and look if you find libmex.a somewhere.
Note that is seems you'll need [MATLAB]/bin/glnxa64 in the LD_LIBRARY path (if not already there).
What you can do alternatively anyways is setting up the compiler inside Matlab to be verbose and inspect what's printed on the command prompt There should be the whole command line including all flags / include folder you'll need. You'll find the option somewhere in the preferences. Not sure where on Linux.

Hi,
I am still getting the message "The Matlab path you entered seems valid, but this wizard
can't locate the Matlab extern include path in the sub-directory /extern/include"
Is it possible (when you have time) to go over the code::blocks script wizard and all the settings together?
Or, would be possible to have the matlab script implemented within the next nightly build (like in the win version)?
I am really sorry for bugging you so much, but I do really love this compiler 8)

What I see from a quick look:
This line:
--- Code: ---if (!IO.DirectoryExists(dir_nomacro + _T("/media/school/MATLAB/R2010b/extern/include")))
--- End code ---
...cannot work and will always return false. Notice that you enter the patch to Matlab in the wizard - so in your case it's /media/school/MATLAB/R2010b. If you combine the path entered as you do you get the following directory:
/media/school/MATLAB/R2010b/media/school/MATLAB/R2010b/extern/include
...which does not exist - that's what the wizard complains.
Look: I can't do a wizard for Matlab under Linux as I don't have Matlab under Linux and I won't commit things that most likely will not work as they are untested. I'll need your help for the trials. BTW: Hard-coded path's should not be in the wizard anyways. The wizard asks for a base directory. All other directories in the wizard should either be relative or in combination with the base directory.
zergling:
Thank you for your help!
Finally I was able to go over the script wizard :D
The only problem it that I do not know which header files I have to include...
By default I have #include <windows.h> that is for a windows system.
This is what I have done so far with the matlab script wizard.
By the way, can I remove all the lcc references in the script?
