initpackage
initialize a package of local models
The initpackage command initializes a package of local models from
their source code and from a model component description file in model.dat
format which defines the component's name, type, function call, and its
parameter names and initial settings. Further details of the file format,
function and parameter specifications are given in Appendix C.
Syntax: initpackage <name><description file>[<directory>] [-udmget |-udmget64]
The <name> argument names the package. For internal reasons package
names must be lowercase: the initpackage command will force lower
case and warn the user if the argument contains uppercase letters. Also
there should be no numerals in the package name.
The <description file> argument specifies the model component
description file. The third argument <directory> is optional and
specifies the location of the source code. If it is not given, the value
of the setting LOCAL_MODEL_DIRECTORY given in the user's Xspec.init
file will be used. Finally, the <description file>, if not specified
as an absolute pathname, will be read from the same directory as the
source code.
Another optional argument is -udmget, for local model libraries
containing Fortran code which makes use of XSPEC's now-obsolete udmget
function for dynamic memory allocation. None of the functions in XSPEC's
built-in models library use udmget anymore, and the necessary xsudmget.cxx
file no longer resides there. If a user still requires this code for
their own local models, they should add -udmget at the end of
the comamnd line. initpackage will then copy the files
xsudmget.cxx and xspec.h into the user's local model directory.
initpackage performs the following tasks:
- reads the model description file
- writes code that will load the new component calculation functions
- writes a makefile that will drive the compilation and installation of the new code
- invokes the compiler and builds the library.
A separate command, lmod, actually loads the library. This two step
process makes it easier to determine where the user is during the
process if compilation failures arise. Further, if the model is complete
and working correctly, only the lmod command need be invoked.
initpackage can also be run as a stand-alone program outside
of XSPEC. When used like this however, after initpackage has
finished the user must manually run hmake to build their library.
XSPEC performs this part automatically using a script file.
This command is now also supported on Cygwin. The former Cygwin-only
static_initpackage command has been removed.
