Saxon » SaxonC

Reported by Tony Graham:

From the 'pkg-config' page at [1]:

pkg-config is a helper tool used when compiling applications

and libraries.

See also "Guide to pkg-config" at [2].

If Saxon/C is to play nicely with other Linux, etc., packages, you may

want to look at producing a 'pkg-config' file to make it easier for people

building the other packages -- particularly but not limited to people

building using Autotools -- to find how to refer to Saxon/C when compiling

and linking.

Here's what I've been faking as 'saxon-c.pc':

prefix=/usr/local/src/saxon-c/Saxonica/Saxon-HEC0.1
exec_prefix=${prefix}
libdir=${exec_prefix}
pkgincludedir=${prefix}/Saxon-C-API


Name: Saxon/C
Description: Saxon/C
Version: 0.1
Libs: -L${libdir} -lsaxon
Cflags: -I${pkgincludedir} -I/usr/lib/jvm/java-6-openjdk-amd64/include

and here's what I've put in 'configure.ac' for xmlroff:
