[Fwd: [Cp-tools-discuss] Building gjdoc+gnujaxp with gcj 4.0]

[Mark Wielaard <mark at klomp dot org>]

Hi gcj hackers,

Since it was pointed out that not everybody is subscribed to the
cp-tools-discuss list (the mailinglist for GNU Classpath tools) I
thought forwarding this message might be appropriate since I know lots
of people are really waiting for this. (At least I was really waiting
for a simple 3 step setup to start playing with this!)

Some additional info:
export CVS_RSH="ssh" and then
gjdoc CVS is:
cvs -z3 -d:ext:anoncvs@savannah.gnu.org:/cvsroot/classpath co gjdoc
gnujxp CVS is:
cvs -z3 -d:ext:anoncvs@savannah.gnu.org:/cvsroot/classpathx co jaxp

You can try it out on GNU Classpath when configuring with --enable-gjdoc
(it doesn't completely work yet [there is strange error when generating
the documentation for javax.naming.event], but for smaller selection of
packages it works nicely - just generated all documentation for the
java.applet, java.awt and java.beans and subpackages for example).

Happy docing!

Thanks Julian for all your hard work on gjdoc.
Thanks Chris for all your hard work on gnujaxp.
Thanks gcj and GNU Classpath hackers for all your hard work!

Cheers,

Mark

• Subject: [Cp-tools-discuss] Building gjdoc+gnujaxp with gcj 4.0

Here are instructions for building a standalone gjdoc binary with gcj 4.0. Of course this is only a preliminary solution until the autotooled build is fixed.

-> fetch gcc cvs head, compile and install.

I tested these instructions with gcj (GCC) 4.0.0 20041125 (experimental) which I configured as follows:

--program-suffix=-4.0 --enable-languages=java --with-system-zlib --enable-java-awt=gtk --disable-static --disable-checking --disable-multilib

Current cvs head is known to fail if srcdir==builddir, so choose an alternate build directory.

-> make sure the correct gcj is on your path by doing gcj --version

-> get latest gjdoc and gnujaxp sources from cvs head

-> for now, apply the attached patch to gnujaxp. It adds missing imports, removes static bindings to libxmlj, and fixes a bug in the implementation of XSLT's substring function.

-> change to some temporary build directory

-> execute the following:

JAXP_ROOT_DIR=/path/to/jaxp \
	GJDOC_ROOT_DIR=/path/to/gjdoc \
	make -f /path/to/gjdoc/examples/Makefile

-> you should end up with a binary called "gjdoc" in the current directory.

Known issues:
- since gnujaxp doesn't correctly support disable-output-escaping ATM, a couple of &nbsp;s end up in the output.
- if you select an alternate stylesheet and click on a link, the stylesheet is reverted to the default.

Julian
