Sorry for not fixing this earlier, everyone.  I'm doing my work on Fedora
Core 3 x86 with stock gcj and autotools, etc.  I've tried with the BC ABI
branch of gcj as well and I get similar results.

I've attached a few files:

* buildgnujaxp.patch -> patch to enable gnujaxp to be built with autotools
                        and gcj (still a work-in-progress)
* buildgjdoc.patch -> patch that I would like to apply to gjdoc with some
                      fixes for building against gnujaxp (and some minor
                      build fixes)

Both patches should apply against CVS head of each.  What I've been
doing to test is:

---------------------------------------
# Set up directory structure and check out sources
mkdir build sources
cd sources
cvs -z3 -d:ext:address@hidden:/cvsroot/classpath co gjdoc
cvs -z3 -d:ext:address@hidden:/cvsroot/classpathx co gnujaxp

# Build gnujaxp (in same dir ... working on that :)
cd gnujaxp
patch -p0 < ~/buildgnujaxp.patch
rm -rf autom4te.cache aclocal.m4 config.guess config.sub ltmain.sh; aclocal
./configure
make
su
make install

# Patch & build gjdoc (in separate dir)
exit
cd ../gjdoc
patch -p0 < ~/buildgjdoc.patch
rm -rf autom4te.cache aclocal.m4 config.guess classes config.sub ltmain.sh; 
aclocal
cd ../../build
mkdir gjdoc
cd gjdoc
../../sources/gjdoc/autogen.sh
./configure
make
su
make install
---------------------------------------

This should install gnujaxp and gjdoc in /usr/local and then you should be
able to run gjdoc like so (I've been trying against the Java-GNOME
libgtk-java sources):

cd ~/sources/java-gnome/libgtk-java/src/java
CLASSPATH=/home/overholt/sources/gjdoc/src/resources gjdoc -d `pwd` org.gnu.gtk

I'm having issues with:

1. the resources ... we should compile the txt files that gjdoc is
   referencing as gcj resources or something
2. java.util.regex.PatternSyntaxException: At position 108 in regular
   expression pattern (in AuthorTaglet.java) [1]
3. I/O warning : failed to load external entity "../gjdoc_common.xsl"
   compilation error: element include
   xsl:include : unable to load ../gjdoc_common.xsl

I get 2. and 3. with libgcj but not IBM's 1.4.2 JVM, so I guess 2's a
problem with java.util.regex in libgcj.  3. I'm not so sure about.  Anyone
have any ideas?  Let me know if the above instructions are borked in some
way.

HTH,

Andrew
