[Cp-tools-discuss] Compiling gjdoc from CVS with automake

[Alex Lancaster]

Hey folks,

Lots of recent activity here on the mailing list and CVS on gjdoc!
Thanks to Julian adding a bunch of new features.  It's been a bit
quiet of late... so I thought I'd jump in and try out Andrew
Overholt's new autotool'ed gjdoc, but have run into some problems with
linking.

First I compiled gnujaxp.jar and libxmlj from the CVS of the
classpathx/jaxp project.  That seemed to go fine.  It created shared
libraries for libxmlj but only a jar file for gnujaxp.jar (no shared
libraries, which it seems to have problems finding later).

Then I compiled gjdoc pointing CLASSPATH to the the gnujaxp.jar file
at configure-time, and LD_LIBRARY_PATH at compile-time set to find the
libxmlj.so shared library and using gij as the Java runtime ("java")
and it all goes fine until the linking phase:

$ LD_LIBRARY_PATH=/home/alex/packages/classpath/lib make
make  all-am
make[1]: Entering directory `/home/alex/build/gjdoc' /bin/sh ./libtool 
--mode=link gcj

collect2: ld returned 1 exit status
make[1]: *** [gjdoc] Error 1
make[1]: Leaving directory `/home/alex/build/gjdoc'
make: *** [all] Error 2

I do not have a full installation of classpath itself, but just gcj
which seems sufficient for most of the compile.  The
configure.ac/Makefile.am seems to be setup to look for a shared
library version of javax.xml.parsers, but it already appears in the
jar file and the jaxp configure/compile didn't create a shared
library:

$ jar tvf /home/alex/packages/classpath/share/java/gnujaxp.jar

javax/xml/parsers/DocumentBuilderFactory.class
<snip>

I was wondering what the requirements of Andrew's gcj/classpath
toolchain is in order for gjdoc to compile?  For reference here's my
autotools/gcj info on Fedora Core 2:

$ rpm -q autoconf automake libtool libgcj gcc-java
autoconf-2.59-3
automake-1.8.3-1
libtool-1.5.6-1
libgcj-3.3.3-7
gcc-java-3.3.3-7

Thanks, 
Alex
