thank you for you reply
the program is KNIT a scientific software,
concerning libraries actually there are some libraries having the same name, because at first the program hasn't been compiled because it didn't find some libraries although there existed which oblige me to copy almost all header files that the compilation needs to /usr/include and the libraries to /usr/lib. So there are libraries having the same name.
What I was trying to get at: are there libs for different versions
of your software available on the system? That's what it looks like
to me. Hint: an older version of the lib is visible to the linker,
but you really need the newer one that exports the symbol it can't
find in the old one.
actually when I see the dependences of the compilation of the program, I build them manually with sources,but I realised after that there are some libraries were already installed, i dont know for exemple when I did a research for some libraries I got these libraries "for libpython" libpython2.6.so libpython2.6.so.1.0 ibpythonmethod-2.7.so libpythonmethod-2.6.so and for liblapack
so as I understand I have to uninstall older versions so that the linker would not see the older that don't have the symbol?
but for all libraries or just some of them.
