library file not being recognized during mex compile
I had previously been able to compile my mex file using the command in Matlab:
>> mex CMEXsfcn_code.c MyLibrary.lib
Somewhere along the line, I started having problems with this compile process, and now when I execute the above command, the .lib file (the same version of which is still contained in my working directory) is now not recognized, and I get a string of error messages relating to functions contained in the .lib file that are used in the .c file.
Does anyone have any ideas about why, even though I'm still working in the same directory and using the same files, the conte...Compiling MEX-file with external library
I am trying to compile a MEX-file, which uses an external library
function. The library is available as "tcdlls.lib".
But performing the compilation I get the following error. I have tried
also copying the .lib file to the working directory, but this did not
help. The library-file is correctly spelled. Using Visual Studio or
LCC-compiler did not make any difference. What is going wrong?
Thank you very much,

I am trying to compile a set of C files to create MEX dynamic library. I have done it successfully for Windows 32 bit & 64 bit. Now I am trying to do the same on a MaC. Every piece of code used for the windows is the same besides having changed a few libraries e.g. while doing it on windows I used the vcf2c.lib to compile fortran to c generated code and in the MaC I am using the f2c.lib.

I want to speed up my Matlab program which uses many FFT operation by writing a mex file and using FFTW library.

- downloaded the latest FFTW and created the *.lib files according to this Tutorial:

I have the fallowing problem
I want to use certain time consuming matlab functions in C/C++ with other c++ Librarys IN an MEX File which I can start in Matlab.
I compiled with MCR the time consuming matlab functions too a shared library and want to use them now in a mex file...
(Up to now I have linking problems in the MEX file)
I have read the fallowing in the forum:
It is not possible to incorporate Matlab compiled file into mex, because there is a conflict between MCR and Matlab.
Is this really correct?
Is there a way of doing this, or do I need to start the application direct...build a static library instead of a dynamic one with MEX compiler
I m looking for an option of the mex compiler in order to produce a static mex file with all the code, that it needs, already inside it.
which can substitute all the external references inside my c code with the real code from the external library.
i tried to do that because I created a mex file to put inside a 2ndlevel sfunction block

It appears that the syntax have changed, and I have some trouble

I'm writing a C program that can be called from matlab as well as from a console. That means, I have a main(...) as well as a mexFunction(...).
I have no problems when compiling with mex, but I get linker errors when I try to compile it with another C compiler like gcc. This of course happens, because some libs are missing. But which libs does the compiler need to succeed? I tried several folders in the MATLAB/extern area, but had again linker errors. Is it possible at all to compile a file containing calls to mex.h without mex?

I wonder if someone has the experience of compiling a matlab object
into a dll. I implemented a class in which I would like to use it in

multiple times whenever I make calls to the library. Is there a way
to do the following:
- Create a wrapper for the class instantiation, return the address of
the object to the caller
- Create other wrappers that accept the object address as argument
and use it to call the object methods
- caller can now reuse the object as many times as he wants.
- destroy the object when finish

I've searched nearly one hour for this but found nothing usefull :-/
So my question is simple :
Is it possible to link a c compiled application with a C++ compiled
If yes, how would it possible.. (I guess this would be indirectly
posible by using some wrapper around the c++ library, but I'm aboslutely
not wanting to do that in my case, well at least if I have to write that
wrapper manually myself).
I looked at gcc,g++ man pages, gcc online documentation, .. but can't
even find a beginning of info related to that :-/
