I have found a solution to this issue. As before, it helps to setup
LD_LIBRARY_PATH before running launcher.
Lets be clear - it only helped to setup LD_LIBRARY_PATH before for
reasons unknown. W/o my recent change, it worked fine on Ubuntu 6
but not on Suse...
If it finds required PATHs it
doesn't re-execute itself. Pathes looks like:
path[0] = /home/ivan/svn/drlvm/trunk/build/deploy/jre/bin/default
path[1] = /home/ivan/svn/drlvm/trunk/build/deploy/jre/bin/
BTW, I have found a bug in the path checks. Giving only first path
will satisfy the condition in the code and will prevent execv(), but
VM will fail to run:
Ha! yes, of course. My bad. Obviously if the needed path is a
substring of a path that's already there, it does the wrong thing.
Doh :)
export #LD_LIBRARY_PATH=/home/ivan/svn/drlvm/trunk/build/deploy/jre/
bin/default
#./deploy/jre/bin/java Test
java/lang/UnsatisfiedLinkError : Failed loading library
"libhyzlib.so": DSO load failed
I'm working on the fix.
Ok. I think it's straightforward - look to see if the full string is
there by seeing if
*(ptr + strstr() + 1) == either null or separator
Back to the issue - this means that we can't debug across the execv()?
