Hi all,
We have a issue with dlsym() on symbols imported by a library that was
loaded with dlopen(). Our code loads the libssl with dlopen() and then
do a dlsym() on several symbols. This works for all symbols exported
by libssl itself but fails for symbols exported by libcrypto. Libssl
is dynamically linked to libcrypto and should be loaded for libssl. I
did a truss and the FreeBSD loader loads libcrypto but does not read
anything from the file pointer.
could you post a sample code fragment which illustrates the problem you
are seeing?
Sure, attached is a simple example that tries to load the symbol
CRYPTO_set_id_callback from a libssl handle. The symbol is located in
libcrypto and NOT in libssl. Because libssl is dynamically linked to
libcrypto I would expect the loader is able to find the symbol, but
that's not the case on freebsd.
cheers
