Hi,
hmm I used the LD_LIBRARY_PATH several times with
gdb and it worked.
How did you see that the LD_LIBRARY_PATH is correct before
the last lib? Did you need it before or is the LD_LIBRARY_PATH
only needed for the last library?
I think you haven't made a mistake by setting the LD_LIBRARY_PATH
but perhaps you can check again if you set it for e.g. lib is in
/home/test/opt/lib
csh compatible shells with
setenv LD_LIBRARY_PATH /home/test/opt/lib
or for bourne shell compatible shells
LD_LIBRARY_PATH=/home/test/opt/lib
export LD_LIBRARY_PATH
Perhaps that could help?
Bye
Roland
