ok thanks , first of all as one of you said, the library is not there, it is on this path /usr/lib sorry for that:
root@neoideo-desktop:/usr/lib# ls | grep libgtkglextmm
i tried doing as you said, with this actual path not the other one.
but didnt work, the same error message appears.
tried adding a new line to /etc/ld.so.conf so now it is
neoideo@neoideo-desktop:~$ cat /etc/ld.so.conf
but when i run the app im still getting the same error
do i have to get rid of the 1.0 version of libgtkglextmm maybe version 1.2 cannot work because of 1.0 i dont know.
what other option do i have?
many thanks in advance
