rpath for library loading

Show all headers | View raw

Hello,

I hope somebody can explain me a little bit the loader process for 
shared libraries.
I have got a library "libmylib.so", this depends on some other libs. I 
have set the rpath
to "./". If I run "ldd libmylib.so" all depend libraries will be found. 
I do not need to setup
any environment variables. All *.so files are in the same directory.

If I load my "libmylib.so" in my application I get an error that the 
depend libraries are not
found. IMHO the rpath flag tells the library in which directory the 
library should be found, so
in my case rpath is "./" the library should be found relative to 
"libmylib.so" eg:

/home/my/lib/libmylib.so
/home/my/lib/libmydepend.so

ldd libmylib.so shows
    libmydepend.so => ./libmydepend.so

So on loading libmylib.so the libmydepend.so should be also loaded
Do I understand it correct?

Thanks

Phil
