Compiler cannot find "tmwtypes.h"

[EDIT: Thu May 12 22:23:56 UTC 2011 Duplicate Removed - MKF]

I tried to deploy a MATLAB shared library on a Linux computer. When I compiled my C code on the linux computer, I got this strange error.

/opt/MATLAB/MATLAB_Compiler_Runtime/v714/extern/include/matrix.h(293): catastrophic error: could not open source file "tmwtypes.h" #include tmwtypes.h ^

maxtrix.h and tmwtypes.h are in the same folder. I am using x86-64 with suse linux

Does anyone know what the problem this is?

Thanks.

What is the exact compiler command that you use? Also, have you tried the documentation example (http://www.mathworks.com/help/toolbox/compiler/f2-972343.html#f2-995584). Are you able to compile this as expected?

Note that matrix.h has the following include line:

 #include <tmwtypes.h>

So that is with <> brackets and not "" double quotes, or in other words the compiler will look for the file in your include directories and not in the same/current directory. To resolve this add the extern/include directory to your include path, for example by using the -I (capital i) switch in your call to gcc/g++.

These are header files, so they should be just text. Can you open them in a text editor? If you can't, check the permissions on the files. Also, check ownership if you are performing this operation under a different user context.

After that, check your environment and make sure that directory can be found during compilation.

The compiler can find "matrix.h" which is in the same folder as "tmwtypes.h". The folder can be found during compilation. I can open tmwtypes.h with an editor. There is no permission issue.

Are the ls -l outputs the same?

Any differences in capitalization?

Otherwise, Kaustubha's questions are very valid.
