Matlab Compiler error (cpp files)

[EDIT: 20110716 09:13 CDT - reformat - WDR]

Good Morning All,

Very new to the Matlab programming or any programming for that matter. I recently tried to use the compiler to translate my code to C++. I have been given an error code of 9 after making an mbuild. If someone could please explain to me what this means or even tell me how to fix it, I would really appreciate it. I have desire to learn the debugging so an explanation would be wonderful for my future errors I know I will make.

Here is the deploy tool command window:

ant:

  <mkdir dir="C:\Users\melissa\Documents\MATLAB\interp1\distrib" />
  <mkdir dir="C:\Users\melissa\Documents\MATLAB\interp1\src" />

Unable to build executable.

I tried to locate the C:\Users\melissa\Documents\MATLAB\interp1\src\interp1.cpp file but it was not there so perhaps I should redo the mbuild?

Since you are attempting to build a C++ shared library, you need to select a C++ compiler using "mbuild -setup". The list of supported compilers for R2010a is here.

LCC is a C-only compiler, so it errors out when attempting to compile C++ code.

Also, the file C:\Users\melissa\Documents\MATLAB\interp1\src\interp1.cpp is a (hidden) intermediate product of MATLAB Compiler - code is generated and compiled immediately into a binary. To my knowledge, the generated code is deleted during termination. This is probably why you do not see the file.

Wow, thank you so much! I really appreciate it.

Wonderful! This was the answer I was looking for, thanks!

Hi everyone, I am using Matalb R2010a and trying to simulate a model. But it is giving error like "Unable to locate 'mexopts.bat', and therefore cannot determine which compiler to use for simulation builds. Use 'mex -setup' to select a supported compiler." I am using windows 7. Please suggest me the solutions. It will be very helpful. Note: I have updated matlab bin with "VS2010MEXSupport" but still its not working. Thanks

[Kaustubha Govind]

Did you run "mex -setup" as the error suggests? Note that you need to have installed a supported compiler.
