Hi,
With reference to this tutorial
How do I create a C shared library with MATLAB Compiler 4.0
that can be used in a Microsoft .NET 2003 project ?
http://www.mathworks.com/support/solutions/data/1-UR7P0.html?1-UR7P0

I had followed this tutorial and was able to compile
successfully with some changes like instead of
$MATLAB\extern\include , I used the complete directory name.

However,the problems arose during runtime.
Upon hitting this line ---foolinInitialize()
A barrage of java errors(I presume) like
Warning: Could not read classpath.txt
Warning: Could not read librarypath.txt... etc..
But I clicked Ok for all these diaglog boxes.

But alas, I received this error,
??? Undefined function or variable 'matlabrc'.

After some googling, I found this site
http://www.mathworks.com/access/helpdesk/help/toolbox/compiler/index.html?/access/helpdesk/help/toolbox/compiler/bqoy17y.html&http://www.google.com.sg/search?hl=en&client=firefox-a&rls=org.mozilla%3Aen-US%3Aofficial&q=%22%3F%3F%3F+Undefined+function+or+variable+%27matlabrc%27.%22&btnG=Search&meta=
This was solution given there
[quote]
Undefined function or variable 'matlabrc'. When MATLAB or
the MCR starts, they attempt to execute the M-file
matlabrc.m. This message means that this file cannot be found.
To work around this, try each of these suggestions in this
order:
-Ensure that your application runs in MATLAB (uncompiled)
without this error.
-Ensure that MATLAB starts up without this error.
-Verify that the generated CTF archive contains a file
called matlabrc.m.
-Verify that the generated code (in the
*_mcc_component_data.c* file) adds the CTF archive directory
containing matlabrc.m to the MCR path.
-Delete the *_mcr directory and rerun the application.
-Recompile the application.
[/quote]

I have tried all the suggestions except this one.."Verify
that generated CTF...... to the MCR path" as I dont know how
check whether mcc_component adds matlabrc.m file to MCR path.

Anyone can give me any suggestion or help on how to go about
solving this..
Thanks.

Hi Hanifa,

For example, after you attempt to run your application you will have a
*_mcr directory. If you search that directory for matlabrc.m you should
find it under *_mcr\toolbox\local

And, if you look inside *_mcc_component_data.c, where it defines
MCC_*_matlabpath_data you should see "toolbox/local/".

However, whether you find "toolbox/local/" in the .c file or not, I
would suggest that you submit a help request at:

http://www.mathworks.com/support/

They should be able to help you troubleshoot this more thoroughly.

Hi Mark, thanks for the reply..
I did find matlabrc.m in the toolbox but under this directory
foolib_mcr\toolbox\compiler\deploy
Anwyway I have put up a bug at website, you have given.
Hopefully, there is a resolution to this problem.

Hi

I am also interested in an answer, because I got the same problem
under Linux.

Unter Windows XP everything works fine.
I do not unterstand why...
