NAME
mkoctfile - Compile dynamic-load modules for GNU Octave

SYNOPSIS
mkoctfile [option]... FILE...

DESCRIPTION
mkoctfile is used to compile C, C++, or Fortran source code in to a dynamically loadable .oct file for octave(1).

OPTIONS

-h, --help
    Print help message.

-Idir
    Add include directory dir to compile command.

-idirafter dir
    Add include directory to second include search path for compilation after '-I'.

-Ddef
    Add definition def to compile command.

-llib
    Add library lib to link command.

-Ldir
    Add library directory dir to link command.

-M, --depend
    Generate dependency files (.d) for C and C++ source files.

-pthread
    Add -pthread to link command.

-Rdir
    Pass -Rdir to link command.

-Wl,option
    Pass option to the linker such as -Wl,-rpath=...

-W...
    Pass flags to the compiler such as -Wa,option.

-c, --compile
    Compile, but do not link.

-o file, --output file
    Output filename. Default extension is ".oct" (or ".mex" if --mex is specified) unless linking a stand-alone executable.

-g  Enable debugging option for all compilers.

-p VAR, --print VAR
    Print configuration variable VAR. There are three categories of variables:

    Octave configuration variables that users may override with environment variables. These are used in commands that mkoctfile executes.

        INCFLAGS                    XTRA_CXXFLAGS

    Octave configuration variables as above, but currently unused by mkoctfile.

    Octave configuration variables that are provided for informational purposes only. Except for OCTAVE_HOME and OCTAVE_EXEC_HOME, users may not override these variables.

    If OCTAVE_HOME or OCTAVE_EXEC_HOME are set in the environment, then other variables are adjusted accordingly with OCTAVE_HOME or OCTAVE_EXEC_HOME substituted for the original value of the directory specified by the --prefix or --exec-prefix options that were used when Octave was configured.
