Thank you, Andrew, I had already tried to do so.
Previously I learned the hard way about the ecj.jar issue, so I ran
the.../contrib/download_ecj script (which downloaded the ecj.jar from
the predefined site) to install the ecj.jar into the trunk directory, I
then ran the configuration again so the ecj.jar would be staged into my
target for "make ... install".
In fact, I do have ecj.jar installed in my target tree: /usr/local/gcj.
I even tried adding it to the include parameter and still get the same
result. Maybe I'm not using the correct parameter syntax??
plug local # pwd
/usr/local/gcj/usr/local
plug local # find . -name '*ecj*.jar'
./share/java/ecj.jar
plug local # export LD_LIBRARY_PATH=/usr/local/gcj/usr/local/lib

OK, so we need to know why that happened. It might be a bug in gcj or you might not have configured gcc correctly. My guess is the latter, but you never know. Please look at the config.log in the top of the gcc build directory, and cut-n-paste the configure line that's there. I think I know what's wrong, but I'll need to see it to be sure.

If this path is hardcoded then I'd say that's a bug. Well, it's just compiled with gcj -Djava.class.path=$(ECJ_JAR) It's a longstanding bug that ecj1 is not precompiled: it's interpreted from the jarfile. If we fix that bug by precompiling ecj1, then this other bug will be fixed too. Andrew. ^ permalink raw reply [flat|nested] 12+ messages in thread

All becomes clear. I've never come across anyone using DESTDIR=path-to-rootdir before, which is why I've never seen this bug. The usual way is to configure with --prefix=path-to-rootdir followed by "make install". I'll have a look at fixing this. Andrew. ^ permalink raw reply [flat|nested] 12+ messages in thread
