Making progress...
Ok, the problem with execv() has been solved. It wasn't finding the
path because of a stupid mistake on my part. Here was the problem:
1047 if (newPathToAdd[i] != NULL && strstr(oldPath,
newPathToAdd[i]) != 0) {
(gdb) p newPathToAdd[i]
$2 = 0x8067ae8
"/u/u12/anavabi/Harmony/enhanced/drlvm/trunk/build/deploy/jre/bin/default"
(gdb) p oldPath
$3 = 0xbfe4c554
"/homes/anavabi/Harmony/enhanced/drlvm/trunk/build/deploy/jre/bin/:/homes/anavabi/Harmony/enhanced/drlvm/trunk/build/deploy/jre/bin/default"
I had to change /homes/anavabi to /u/u12/anavabi in LD_LIBRARY_PATH and
then the paths are found, so it never gets to the execv line. FYI, the
default directory is the one that should not contain a trailing slash.
Thanks for the help on this one.
Now gdb is working like a champ, but "java helloworld" is still having
problems. Here is a stack trace of what happens when I try to run
helloworld in gdb:
(gdb) run helloworld
Starting program:
/u/u12/anavabi/Harmony/enhanced/drlvm/trunk/build/deploy/jre/bin/java
helloworld

Let me know if there is any other debugging information I can provide.
Thanks,
