Yeah, it looks like the configure script does not know where to
find your JNI libs. Perhaps that error message about
"your JVM install is broken or corrupted" is not all
that helpful in the case where the libs can not even
be found.
If you open up tcljava.m4 and look at the AC_JAVA_JNI_LIBS
macro, you will find the place where it tries to find
the JNI libs for a given system configuration. It does
this by looking for "known layouts". It works on most
configurations but it would seem that yours needs to
be added to the script. Are you using a Sun JVM,
the one from blackdown, or the one from IBM? They
each might install the native libs in a different
spot (yeah, it sucks but what can be done???).
So first, cd to /usr/lib/java and run
find . -name "libjava*.so*"
find . -name "libjvm*.so*"
find . -name "libhpi*.so*"
And see what that prints. That should tell you
where the libs for your system live. If you
have both native and green thread libs, make
sure you use the native thread ones.
You might also want to put in an extra check
to see if ac_java_jvm_jni_lib_flags is ""
and then raise an error of print a better
message like "Your JVM configuration is
not known, please edit the AC_JAVA_JNI_LIBS
macro in tcljava.m4 to add support for it."
