The following is sorted out compiler error messages and solutions proposed MathWorks please refer to 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:. Can not 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: Can not 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% incorrec t 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
is a script M-file which can not be compiled with the current Compiler. The MATLAB Compiler can not 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. Error: File: FileName Line: # Column: #! = ISNE ~ = INST. Use the matlab relational operator ~ = (not equal). Error: file: filename line: # colorn: # ( ) indexing must appear last in an index expression. If you use ordinary array indexing () to index into an expression, it must be last in the index expression.
