Cannot find MEX function when executing C
显示 更早的评论
System
- Ubuntu running R2010a
Error
- Undefined function or method 'mex' for input arguments of type 'char'.
Compilation call
/usr/local/matlab/bin/mcc -m -v -R -nodisplay remote_estimation.m
Context
- Compiling .m file that has the follwing code:
function remote_estimation()
%#function mex
mex('/path/to/file.c');
When executing in matlab it works, after compiling and executing the binary, it gives the error described above

The mex command does not perform magic tricks, it simply starts the compiler. Unfortunately mex has grown to a very obfuscated piece of code since Matlab 4. It are some M-, Perl- and BAT-files, while the last are not executed, but parsed by teh Perl functions.
If you find out the parameters used for starting the compiler, you can start the compiler by a single system call also.

It is likely that the "mex" command is not supported for deployment. Is there a reason that you can't simply include your MEX-file with your application's CTF archive (using the mcc -a option)? Since the compiled application is platform-specific, the MEX-file from your machine should be sufficient on all target machines.

Does the generated mex code call the MATLAB routines, or is it pure C and OS calls? If it is pure C and OS calls, then can the toolbox emit C without the the mex headings, in a form that you could call upon a C compiler and generate a dynamic library that you could loadlibrary() on ?
