[Cp-tools-discuss] gjdoc with jikes and jamvm?

[Rupert Mazzucco]

Hello,

can gjdoc-0.7.7 be built with classpath, jikes and jamvm?  It doesn't 
seem to work
for me.  I have jamvm-1.4.3, jikes-1.22, and classpath-0.92 (built with 
jikes)
installed in /usr, also apache-ant-1.65 in /usr/share/ant.

I configure with

 JAVA=jamvm CLASSPATH=/usr/share/classpath/glibj.zip ./configure 
--prefix=/usr
 --sysconfdir=/etc --localstatedir=/var --mandir=/usr/share/man       
 --infodir=/usr/share/info 
--with-antlr-jar=/usr/share/ant/lib/ant-antlr.jar

which seems successful:
 ...
 checking if jamvm works... yes
 checking for gcj... no
 checking for jikes... jikes
 checking if jikes works... yes
 configure: using ANTLR parser generator in 
/usr/share/ant/lib/ant-antlr.jar
 ..
 checking for java.util.regex.Pattern class... yes
 Native compilation disabled as gcj has not been found
 configure: creating ./config.status
 etc.

When making, jikes compiles some class files successfully, but then the 
build goes
down with some thousand "Semantic Error"s.  (I'll give only the start 
and some examples
for the different kinds of errors, there are many more where they come 
from):

You get the idea.  The main problem seems to be that it cannot find some 
classes,
but which component is at fault?  Here is what ant knows about my java 
setup:

I could not compile ant from source either and tried to teach it about 
jamvm and jikes with this ant.conf:

 $ cat /etc/ant.conf
 /ANT_HOME=/usr/share/ant
 JAVACMD=/pkg/tools/jamvm
 usejikes=true
 JIKESPATH=/usr/share/classpath/glibj.zip

But was that enough?  There is this message about tools.jar, which is 
probably
Sun JDK stuff.  I don't know what its equivalent in classpath is, nor 
how to teach
ant about it.  But it doesn't seem to be related to those antlr.errors 
anyway,
or is it?

Any ideas appreciated.

Thank you,
Rupert
