Hi Dan, the trick about omitting the --enable-java-gc=boehm does not
work, in fact from the configuring instructions of gcc it says that if
it is not specified it uses it by default.
The Error is:
creating gcj-dbtool
./gcj-dbtool -n classmap.db || touch classmap.db
Unexpected error from pthread_mutex_trylock
/bin/sh: line 1: 9997 Aborted ./gcj-dbtool -n classmap.db
make[3]: Leaving directory `/sources/gcc-build/i686-pc-linux-gnu/libjava'
make[2]: Leaving directory `/sources/gcc-build/i686-pc-linux-gnu/libjava'
make[1]: Leaving directory `/sources/gcc-build'
However I think it is something deeper, in fact, making check for Gc6.6
reports this error:
