Error using mex (line 206) Unable to complete successfully.
Why for the error
The mex.c showed as follows
function varargout = mex(varargin) %MEX Compile MEX-function % Usage: % mex [options …] file [files …] % % Description: % MEX compiles and links source files into a shared library called a % MEX-file, executable from within MATLAB. The resulting file has a % platform-dependent extension. Use the MEXEXT command to return the % extension for this machine or for all supported platforms. % % MEX accepts any combinations of source files, object files, and % library files as arguments. % % The command line options to MEX are defined in the "Command Line % Options" section below. % % MEX can also build executable files for stand-alone MATLAB engine % and MAT-file applications. See the "Engine/MAT Stand-alone % Application Details" below for more information. % % You can run MEX from the MATLAB Command Prompt, Windows Command % Prompt, or the UNIX shell. MEX is a script named mex.bat on Windows % and mex on UNIX, and is located in the directory specified by % [matlabroot '/bin']. % % The first file name given (less any file name extension) will be the % name of the resulting MEX-file. Additional source, object, or % library files can be given to satisfy external references. On UNIX, % both C and Fortran source files can be specified when building a % MEX-file. If C and Fortran are mixed, the first source file given % determines the entry point exported from the MEX-file (MATLAB loads % and runs a different entry point symbol for C or Fortran MEX-files). % % MEX uses an options file to specify variables and values that are % passed as arguments to the compiler, linker, and other tools (e.g. % the resource linker on Windows). Command line options to MEX may % supplement or override contents of the options file, or they may % control other aspects of MEX's behavior. For more information see % the "Options File Details" section below. % % The -setup option causes MEX to search for installed compilers and % allows you to choose an options file as the default for future % invocations of MEX. For compiler configuration information, % use the mex.getCompilerConfigurations function. % % For a list of compilers supported with this release, refer to % the Supported and Compatible Compiler List at: % http://www.mathworks.com/support/compilers/current_release/ % % Command Line Options Available on All Platforms: % -<arch> % Build an output file for architecture arch. To determine the % value for arch, type "computer('arch')" at the MATLAB Command % Prompt on the target machine. Note: Valid values for arch % depend on the architecture of the build platform. % -c % Compile only. Creates an object file but not a MEX-file. % -compatibleArrayDims % Build a MEX-file using the MATLAB Version 7.2 array-handling API, % which limits arrays to 2^31-1 elements. This option is the % default, but in the future the -largeArrayDims option will be % the default. % -D<name> % Define a symbol name to the C preprocessor. Equivalent to a % "#define name" directive in the source. Do not add a space after % this switch. % -D<name>=<value> % Define a symbol name and value to the C preprocessor. Equivalent % to a "#define name value" directive in the source. Do not add a % space after this switch. % -f optionsfile % Specify location and name of options file to use. Overrides % MEX's default options file search mechanism. % -g % Create a MEX-file containing additional symbolic information for % use in debugging. This option disables MEX's default behavior of % optimizing built object code (see the -O option). % -h[elp] % Print this message. % -I<pathname> % Add pathname to the list of directories to search for #include % files. Do not add a space after this switch. % -l<name> % Link with object library. On Windows, name expands to % "<name>.lib" or "lib<name>.lib" and on UNIX, to % "lib<name>.LIBEXT", where LIBEXT is platform dependent. Do not % add a space after this switch. % -L<directory> % Add directory to the list of directories to search for % libraries specified with the -l option. On UNIX systems, you % must also set the run-time library path. Do not add a space % after this switch. % -largeArrayDims % Build a MEX-file using the MATLAB large-array-handling API. This % API can handle arrays with more than 2^31-1 elements when % compiled on 64-bit platforms. (See also the -compatibleArrayDims % option.) % -n % No execute mode. Print out any commands that MEX would otherwise % have executed, but do not actually execute any of them. % -O % Optimize the object code. Optimization is enabled by default and % by including this option on the command line. If the -g option % appears without the -O option, optimization is disabled. % -outdir dirname % Place all output files in directory dirname. % -output resultname % Create MEX-file named resultname. The appropriate MEX-file % extension is automatically appended. Overrides MEX's default % MEX-file naming mechanism. % -setup % Specify the compiler options file to use when calling the mex % function. When this option is specified, no other command line % input is accepted. % -U<name> % Remove any initial definition of the C preprocessor symbol % name. (Inverse of the -D option.) Do not add a space after this % switch. % -v % Verbose mode. Print the values for important internal variables % after the options file is processed and all command line % arguments are considered. Prints each compile step and final link % step fully evaluated. % name=<value> % Override an options file variable for variable name. % This option is processed after the options file is processed % and all command line arguments are considered. See the % "Override Option Details" section below for more details. % % Command Line Options Available Only on Windows Platforms: % @<rspfile> % Include contents of the text file rspfile as command line % arguments to MEX. % % Command Line Options Available Only on UNIX Platforms: % -cxx % Use the C++ linker to link the MEX-file if the first source file % is in C and there are one or more C++ source or object files. This % option overrides the assumption that the first source file in % the list determines which linker to use. % -fortran % Specify that the gateway routine is in Fortran. This option % overrides the assumption that the first source file in the list % determines which linker to use. % % Options File Details: % There are template options files for the compilers that are % supported by MEX. These templates are located at % [matlabroot '\bin\win32\mexopts'] or % [matlabroot '\bin\win64\mexopts'] on Windows, or % [matlabroot '/bin'] on UNIX. % % These template options files are used by the -setup option to define % the selected default options file. % % Override Option Details: % Use the name=value command-line argument to override a variable % specified in the options file at the command line. When using this % option, you may need to use the shell's quoting syntax to protect % characters such as spaces, which have a meaning in the shell syntax. % % On Windows platforms, at either the MATLAB prompt or the DOS prompt, % use double quotes ("): % mex -v COMPFLAGS="$COMPFLAGS -Wall" … % LINKFLAGS="$LINKFLAGS /VERBOSE" yprime.c % % At the MATLAB command line on UNIX platforms, use double quotes ("). % Use the backslash (\) escape character before the dollar sign ($). % mex -v CFLAGS="\$CFLAGS -Wall" LDFLAGS="\$LDFLAGS -w" yprime.c % % At the shell command line on UNIX platforms, use single quotes ('): % mex -v CFLAGS='$CFLAGS -Wall' LDFLAGS='$LDFLAGS -w' yprime.c % % Engine/MAT Stand-alone Application Details: % For stand-alone engine and MAT-file applications, MEX does not use % the default options file; you must use the -f option to specify % an options file. % % The options files used to generate stand-alone MATLAB engine and % MAT-file executables are named *engmatopts.bat on Windows, or % engopts.sh and matopts.sh on UNIX, and are located in the same % directory as the template options files referred to in the "Options % File Details" section. % % Examples: % The following command compiles "yprime.c", building a MEX-file: % % mex yprime.c % % When debugging, it is often useful to use "verbose" mode as well % as include symbolic debugging information: % % mex -v -g yprime.c % % See also MEXEXT, MEX.GETCOMPILERCONFIGURATIONS, DBMEX, LOADLIBRARY, % PCODE, PREFDIR
