B Error and Warning Messages
B-2
Compile-Time Errors
Error: An error occurred while shelling out to mex/mbuild (error code = errorno). Unable to
build executable (specify the -v option for more information).
The Compiler reports this
error if
mbuild or mex generates an error.
Error: An error occurred writing to file "filename": reason. The file could not be
written. The reason is provided by the operating system. For example, you may
not have sufficient disk space available to write the file.
Error: Cannot recompile M-file "filename" because it is already in library "libraryname". A
procedure already exists in a library that has the same name as the M-file that
is being compiled. For example:
mcc -x sin.m % Incorrect
Error: Cannot write file "filename" because MCC has already created a file with that name, or
a file with that name was specified as a command line argument.
The Compiler has
been instructed to generate two files with the same name. For example:
mcc -W lib:liba liba -t % Incorrect
Error: Could not check out a Compiler license.
No additional Compiler licenses are
available for your workgroup.
Error: Could not find license file "filename". (Windows only) The license.dat file
could not be found in
<MATLAB>\bin.
Error: Could not run mbuild. The MATLAB C/C++ Math Library must be installed in order to
build stand-alone applications.
Install the MATLAB C/C++ Math Library.
Error: File: "filename" not found. A specified file could not be found on the path.
Verify that the file exists and that the path includes the file’s location. You can
use the
-I option to add a directory to the search path
Error: File: "filename" is a script M-file which cannot be compiled with the current Compiler.
The MATLAB Compiler cannot compile script M-files. To learn how to convert
script M-files to function M-files, see “Converting Script M-Files to Function
M-Files” on page 3-10.
Error: File: filename Line: # Column: # != is not a MATLAB operator. Use ~= instead. Use
the MATLAB relational operator
~= (not equal).
