mkoctfile(1)

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.

    FPICFLAG                    XTRA_CFLAGS
    INCFLAGS                    XTRA_CXXFLAGS

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

    AR
    DEPEND_EXTRA_SED_PATTERN
    DEPEND_FLAGS
    FFTW3F_LDFLAGS
    FFTW3F_LIBS
    FFTW3_LDFLAGS
    FFTW3_LIBS
    FFTW_LIBS
    FLIBS
    LIBS
    RANLIB
    READLINE_LIBS

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.
