From: Pascal Mazon <pascal.ma...@6wind.com>
When loading a library "libfoo.so" (depending on "libbar.so", located in an
entirely different folder), with a LD_LIBRARY_PATH=/path/to/libfoo.so", it
returns an error:
EAL: ./libfoo.so: cannot open shared object file: No such file or directory
If the first dlopen() fails (here, because it can't find all dependencies),
the code requires for a second dlopen() that looks for "./libfoo.so". It
turns on pathname matching, which does not use LD_LIBRARY_PATH. As a result,
it fails because it cannot find "./libfoo.so".
The error message matches the error of the second dlopen(), not the first's.
Do not try to look for a different library ("./"-prefixed) than the one
provided in argument. Let the dynamic library management handle it, just
provide an appropriate LD_LIBRARY_PATH.
