my own .so lib Ubuntu->Debian migration (cannot open shared library)

Recently i migrated my self from Ubuntu to Debian, (fortunetly didn't delete old OS) On Ubuntu I had written litle library called

libmyh.so

I've used it in other app by 

g++ (...) -lmyh -L../codeSamples/myh/lib

and it ran perfectly, but on Debian witch this same makefile i get:

./GLUI.out: error while loading shared libraries: libmyh.so: cannot open shared object file: No such file or directory

any clue wat could be wrong?

Solution

  • .so files are not linked by g++, because they are not static libraries (which end with .a) or compilation objects (.o).

    Instead, set the path from where to load dynamic libraries:

    export LD_LIBRARY_PATH=/path/to/codeSamples/myh/lib
./GLUI.out

    As this is not related to Debian vs Ubuntu, I think you have set this variable on your Ubuntu system but not on the Debian one.
