.SH NAME
mkoctfile \- Compile dynamic-load modules for GNU Octave
.SH SYNOPSIS
\fBmkoctfile\fP [\fIOPTION\fP]... file...
.SH DESCRIPTION
\fBmkoctfile\fP is used to compile C, C++, or Fortran source code in
to a dynamically loadable \fI.oct\fP file for
.BR octave (1).
.SH OPTIONS
.TP 8
\fB\-h\fP, \fB\-?\fP, \fB\-\-help\fP
Print help message.
.TP
.B \-I\fIdir\fP
Add include directory \fIdir\fP to compile commands.
.TP
.B \-idirafter\fIdir\fP
Add include directory to second include search path after '\fB\-I\fP'.
.TP
.B \-D\fIdef\fP
Add definition \fIdef\fP to compiler command.
.TP
.B \-l\fIlib\fP
Add library \fIlib\fP to link command.
.TP
.B \-L\fIdir\fP

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