On Cygwin the shared library is called e.g.
cygjavalangreflect-1-1-6.dll  Doesn't lt_dlopenext look for the
according .la file and takes the filename from there?

$ sablevm -Yc /usr/share/java/sablecc.jar org.sablecc.sablecc.SableCC simplec.sablecc
./libjavalang
/usr/lib/sablevm/sablevm-classpath/libjavalang
java/lang/UnsatisfiedLinkError

Fine, I see now that I don't have this library available as shared lib.

Ok, now I'll try again.

See you later,
Gerrit
