MATLAB: Do I receive errors when compiling with MEX in MATLAB 7.0.4 (R14SP2) using the Borland C/C++ Compiler 5.0 or 5.02

borlandc:\programcompilationcompilingMATLABmex

When I use the Borland C/C++ Compiler 5.0 or 5.02 with the command

mex yprime.c

I receive the following error:

 Borland C++ 5.2 for Win32 Copyright (c) 1993, 1997 Borland International 
 Error: Could not find file 'Files\MATLAB704\extern\lib\win32\borland\bc50.cpp' 
   D:\PROGRAM FILES\MATLAB704\BIN\WIN32\MEX.PL: Error: Link of 'yprime.dll' failed.

The source of this error is a bug in the Borland C/C++ Compiler 5.0 and 5.0.2 that causes it to fail when called with files whose paths contain spaces. If MATLAB 7.0.4 (R14SP2) has been installed in a directory containing spaces, this error will occur. To work around this issue, install MATLAB to a directory which does not contain any spaces.

The compiling errors are coming from the stdlib.h file. This file is supposed to be a standard ANSI C header file, but in Borlands free compiler this is not the case. Explicitly defining the following symbol alleviates the problem:

 #define __STDC__ 1

The _STDC_ symbol is Borland specific and forces standard C.

Note: We have found several similar caveats with the Borland Free Compiler (v5.5). If possible, creating a C engine application will result in fewer compile and link issues.

MATLAB: Do I receive errors when compiling with MCC in MATLAB 7.0.4 (R14SP2)

This bug occurs when the Microsoft Visual C++ Compiler 6.0 is selected. To work around this issue:

1. Run the following command in MATLAB:

mbuild -setup

2. Select the compiler as prompted.

3. Type the following at the MATLAB command prompt:

cd(prefdir)
copyfile('compopts.bat','compopts_old.bat')
edit compopts.bat

4. Edit line 66 of compopts.bat to read

set IDL_COMPILER=midl /nologo /win32 /I C:\Progra~1\MATLAB71\extern\include

[Note: this specification assumes that MATLAB 7.1 has been installed in C:\Program Files\MATLAB71. Change this directory to match your particular installation directory, if different.]

5. Save the compopts.bat file.

6. Run the MCC command.

You must follow steps 1-6 whenever you change the compiler using MBUILD.

NOTE: It is advisable to install MATLAB in a directory without spaces.
