Re: compilation problems with ecj.jar
The *real* cause is that, for some reason, gcj isn't being passed the
correct path to libgcj.jar in the host system. Instead, this happens:
jc1 /mnt/zebedee/aph/gcc/trunk/libjava/.././libjava/../ecj.jar \
-fhash-synchronization \
-fno-use-divide-subroutine \
-fuse-boehm-gc \
-fnon-call-exceptions \
-fkeep-inline-functions \
-quiet \
-dumpbase ecj.jar \
-mtune=generic \
-auxbase ecj \
-g \
-O2 \
-version \
-ffloat-store \
-fomit-frame-pointer \
-findirect-dispatch \
-fbootclasspath=./:/tmp/prefix/share/java/libgcj-4.3.0.jar \
-o /tmp/ccD80X4c.s
Note that the bootclasspath at this point is wrong: there's no
libgcj.jar in the install dir yet. The first "./" item in the string
is wrong because the .class files we need are no longer in the build
dir: they're in the srcdir.
This oughta do it:
