This is the command gen-ctl-io that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
NAME
gen-ctl-io - generate C interface code for libctl control files
SYNOPSIS
gen-ctl-io [OPTION]... [spec-file]
DESCRIPTION
gen-ctl-io generates C code to import/export the input/output variables used in a libctl
control file. gen-ctl-io generates files like ctl-io.h and ctl-io.c. These files define
global variables, data structures, and functions for the input/output variables, classes,
and function interfaces defined in the spec-file argument, automating the interaction
between C and Guile.
The arguments such as --code and --header are used to control whether ctl-io.c or ctl-
io.h, etcetera, are generated. If no argument is specified then both of these files are
generated by default, for backwards compatibility.
libctl is a free library to aid in interfacing scientific software with the GNU Guile
scripting and extension language. Documentation for it may be found online at the libctl
home page: http://ab-initio.mit.edu/libctl
OPTIONS
--code Generate C (or C++) source code to implement the Guile interface functions. The
default output file name is ctl-io.c (in C) or ctl-io.cpp (in C++).
--header
Generate the header file declaring the interface data types and functions. The
default output file name is ctl-io.h (in C) or ctl-io.hpp (in C++).
--swig Generate a SWIG interface definition file declaring automatic conversions for the
various libctl data types. The default output file name is ctl-io.i.
--cxx Generate C++ code instead of C code.
-o file
Use file as the output file name instead of the defaults (above).
