Upstream explanation is here: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32712 Basically you need to either put ftp://sourceware.org/pub/java/ecj-latest.jar as ecg.jar in /var/tmp/portage/sys-devel/gcc-4.3.0/work/gcc-4.3.0 before calling GCC 4.3's configure or use --with-ecj-jar=filename option... In this case GCC 4.3 will create useful /usr/libexec/gcc/i686-pc-linux-gnu/4.3.0/ecj1 and GCJ will work. If ecj.jar is not found at compilation time then it's up to user to provide ecj1 in $PATH...

I imagine there's a better way then the download_ecj and the ftp dep. it requires, but it's the GCC way of doing it. Maybe, wget ftp://sourceware.org/pub/java/ecj-latest.jar -O ${WORKDIR}/${P}/contrib/ecj.jar is nicer. I'm new to all this :)
Oops, ecj.jar should go in top-dir. So, (with ftp) cd ${WORKDIR}/${P} && ./contrib/download_ecj or wget ftp://sourceware.org/pub/java/ecj-latest.jar -O ${WORKDIR}/${P}/ecj.jar
Yes, this hack will work (I did something similar), but it's not a good long-term solution. What happens if later ftp://sourceware.org/pub/java/ecj-latest.jar will be changed and will only work with gcc 4.10 or something like this? It's create a mess. To fix it properly this file should be mirrored somewhere (probably on Gentoo mirrors) under sane name (something like ecj-20070727.jar), then it should be downloaded as normal file and put in proper place at src_unpack stage.

maintaining any java stuff in gcc is undesirable java team: can you update dev-java/eclipse-ecj so as to provide an `ecj1` symlink ?
I stumbled upon this report while tyring to build "pdftk". Following the suggestions found here, I have installed dev-java/eclipse-ecj and created a symlink from /usr/bin/ecj1 to /usr/bin/ecj-3.3. However, I have not rebuilt gcc because it takes "forever". Building the" pdftk" fails with >>> Compiling source in /var/tmp/portage/app-text/pdftk-1.41/work/pdftk-1.41/pdftk ... make -C ../java_libs make[1]: Entering directory `/var/tmp/portage/app-text/pdftk-1.41/work/pdftk-1.41/java_libs' make -C "/var/tmp/portage/app-text/pdftk-1.41/work/pdftk-1.41/java_libs/gnu_local/java/security"; make[2]: Entering directory `/var/tmp/portage/app-text/pdftk-1.41/work/pdftk-1.41/java_libs/gnu_local/java/security' gcj -march=k8 -O2 -pipe --encoding=UTF-8 --classpath="/var/tmp/portage/app-text/pdftk-1.41/work/pdftk-1.41/java_libs" -c Engine.java -o E ngine.o /usr/lib64/portage/pym/portage_dep.py:39: DeprecationWarning: DEPRECATION NOTICE: The portage_dep module was replaced by portage.dep Unrecognized option : -fbootclasspath=/var/tmp/portage/app-text/pdftk-1.41/work/pdftk-1.41/java_libs/:/usr/share/gcc-data/x86_64-pc-linux -gnu/4.3.1/java/libgcj-4.3.1.jar Should I rebuild gcc?
Given my time constraints, and the fact that the problem has been introduced with gcc version 4.3, I circumvented this problem by reverting to the earlier version of gcc installed on my system, namely version 3.4.4. Unfortunately, this version of gcc was hard masked so I could not emerge gcc version 3.4.4.. The solution was to find an unmasked version earlier than version 4.3 but later than version 3.4.4. Here is how I did it: > emerge -pv '<sys-devel/gcc-4' [ebuild R ] sys-devel/gcc-3.4.6-r2 USE="fortran gcj nls (-altivec) -bootstrap -boundschecking -build -d -doc -gtk (-hardened) -ip28 -ip32r10k -libffi (-multilib) -multislot (-n32) (-n64) -nocxx -nopie -nossp -objc -test -vanilla" 0 kB > USE="gcj" emerge '=sys-devel/gcc-3.4.6-r2' I also followed the directions for upgrading GCC [1]. HTH, [1] http://www.gentoo.org/doc/en/gcc-upgrading.xml
I have maked it work. 1. emerge eclips-ecj 2. sudo vim /usr/bin/ecj1 and where change gjl_main="org.eclipse.jdt.internal.compiler.batch.Main" to gjl_main="org.eclipse.jdt.internal.compiler.batch.GCCMain"
Know someone from where ecj1 come from?
contrib/download_ecj is the acknowledged way of fulfilling this dependency by upstream. Hence others will depend on it so the jar file is hardly going to move. But if you think it's a problem, then you should discuss it with them rather than complaining here. As to 'maintaining any java stuff in gcc is undesirable', it's part of gcc so get over it.
Having an ecj1 symlink won't cut it completely, the build also needs to be supplied with a copy of ecj.jar. By far the easiest way to do this is to patch gcc-4.3.1 to download ecj as upstream specifies.
I've put the patched version in the java-overlay for now but this isn't a permanent solution. Please fix gcc.
Tom Tromey has kindly made the ecj-latest.jar into a symlink which currently points to ecj-4.3.jar. ftp://sourceware.org/pub/java/ So now the Gentoo ebuild can rely on this version for 4.3
I've made the ebuild in java-overlay slightly less evil. No one likes using wget during src_unpack.
I couldn't get this to work, not manually and not with the ebuilds from the java overlay. So I resorted to emerging gcc 4.2 in a separate slot (gcc-4.2 with gcj useflag, gcc-4.3 without), and symlinked gcj and gcjh to the 4.2 version. With this I can emerge "pdftk" again. Not sure if mixing gcc-4.2 and 4.3 like this is a good idea in general. Would love to see a proper fix for gcc-4.3.
What was the problem though?
The problem is the current build of gcj is unusable -- it can't compile anything.
No, I meant what was the problem that Andreas had with the ebuilds from the overlay?
I'm completely lost with this ecj1... I have no /usr/bin/ecj1 and I'm getting (dev-java/eclipse-ecj-3.4-r2): >>> Unpacking ecjsrc-3.4.zip to /var/tmp/portage/portage/dev-java/eclipse-ecj-3.4-r2/work * bootstrapping ecj with /usr/x86_64-pc-linux-gnu/gcc-bin/4.3.1/gcj -C ... gcj: error trying to exec 'ecj1': execvp: Permission denied for hello.java: gcj: error trying to exec 'ecj1': execvp: No such file or directory I have /usr/bin/ecj with "...batch.Main", so when I create symlink for ecj1: * bootstrapping ecj with /usr/x86_64-pc-linux-gnu/gcc-bin/4.3.1/gcj -C ...

My ecj1 is at /usr/libexec/gcc/x86_64-pc-linux-gnu/4.3.1/ecj1, which is where it should be. You definitely used gcc from the overlay, right?
This has been fixed in the tree. Thanks all.
Thanks for doing this. Just for the record, ecj.jar was not removed, it's a new external dependency from gcc 4.3 onwards.
(In reply to comment #21) > This has been fixed in the tree. Thanks all. > When or where is the new ebuild available? (not yet in the standard emerge 2008/09/02)
Please consider revbumping as we still get bug reports about this from people who didn't recompile gcc after the fix.
*** Bug 236398 has been marked as a duplicate of this bug. ***
my gcc is still failing, needs a revdump? seems i'm running the latest one
after re-emerging it works. looks fixed in the portage tree
gcc 4.3.2 is now in the tree, so everyone will be getting that version now anyway.
