Babel Debian Package Current Status

This page documents my effort to package the Babel SIDL compiler for the Debian GNU/Linux operating system.  The upstream authors are at Lawrence Livermore National Laboratories.

Why a Debian package? Being able to type, "apt-get install babel" is a lot easier than downloading, compiling and installing the source. Also, this package puts the various files in their standard Debian places, and includes documentation metadata to link the Babel documentation from Debian doc-base frontends. But perhaps most importantly, having a Debian package allows other Debian packages to depend on Babel and SIDL. In the near future, such packages will include hypre and PETSc, and if Babel lives up to its to its promise, there could be quite a lot more.

Package description:

The babel source package builds six binary packages:

• babel-1.2.0 has the SIDL compiler itself, which consists of the babel-1.2.0.jar Java archive in /usr/share/java following the (proposed) Debian Java policy, and the /usr/bin/babel script which runs it, along with the /usr/share/babel-1.2.0 directory which contains sidl.sidl, the .dtd files, and the repository subdirectory.
• libsidl1.2.0-java has the sidl-1.2.0.jar runtime Java archive file.
• libsidl1.2.0* has the C runtime shared library.
• libsidl-dev* has the C runtime static library, headers, symlinks, and babel-config script needed to develop against the shared library.
• python-babel* has the python runtime modules and headers.
• babel-doc has all of the documentation which ships with the source (ps, pdf, ppt), along with Debian doc-base metadata so this documentation is indexed in frontends like dhelp and dwww.

Questions/issues:

1. It would be nice if variables like docdir and jardir could be defined during the configure process, that would cut down considerably on the patch size. At some point I'll probably generate a patch for upstream.
2. The babel source ships with several other .jar files, but builds just fine using standard Debian versions of these. At some point I'll patch aclocal.m4 to look in the Java archive directory (see previous point) for getopt and xerces, and send these patches upstream.

To do (in roughly decreasing order of priority):

• Write a better manpage for /usr/bin/babel and contribute it upstream.
• Test the babel package with the hello example provided.
