This section identifies some of the more common problems that might occur when
mbuild to create standalone applications.
Options File Not Writable. When you run
mbuild makes a
copy of the appropriate options file and writes some information to it. If the
options file is not writable, you are asked if you want to overwrite the existing
options file. If you choose to do so, the existing options file is copied to a new
location and a new options file is created.
Directory or File Not Writeable. If a destination folder or file is not writable, ensure that the permissions are properly set. In certain cases, make sure that the file is not in use.
mbuild Generates Errors. If you run
mbuild filename and get errors, it may be because
you are not using the proper options file. Run
mbuild -setup to
ensure proper compiler and linker settings.
Compiler and/or Linker Not Found. On Windows®, if you get errors such as
unrecognized command or
file not found, make sure the command-line tools are
installed and the path and other environment variables are set correctly in the
options file. For Microsoft®
Visual Studio®, for example, make sure to run
6.x and earlier) or
vsvars32.bat (MSVC 8.x and later).
mbuild Not a Recognized Command. If
mbuild is not recognized, verify that
is in your
path. On UNIX®, it may be necessary to rehash.
mbuild Works from Shell But Not from MATLAB (UNIX). If the command
mcc -m hello
file. When MATLAB launches a new shell to perform compilations, it executes the
.bashrc script. If this script causes unexpected changes to
PATH environment variable, an error may occur. You can test
this before starting MATLAB by performing the
export SHELL /bin/sh
.bashrc file for problems
PATH environment variable.
Internal Error when Using mbuild -setup (Windows). Some antivirus software packages may conflict with the
mbuild-setup process. If you get an error message during
mbuild -setup of the following
mex.bat: internal error in sub get_compiler_info(): don't recognize <string>
mbuild-setup. After you have successfully run the
setup option, you can re-enable your antivirus
