Hi all, I’m writing an XML-RPC client call under a Tuxedo app
on HP-UX 11 and having run-time troubles due to an Oracle .so being picked up
instead of OpenSSL libraries. My app statically links in the XML-RPC library, libcurl, libssl
and libcrypto, but at run-time it seg-faults with the following trace: #0

Curl_ossl_connect_step2 (conn=0x600000000070cf40, sockindex=0,
timeout_ms=0x9fffffffffffcf10) at ssluse.c:1391 Actually the error was originally in BN_set_word but I
renamed that, and then in BN_mod_inverse and I renamed that (to
S_BN_mod_inverse as you can see above)… The BN_ functions are being
picked up from Oracle’s libnnz10.so instead of libcrypto.a which
I’ve statically linked in. At link time, $ORAHOME/lib is included with a –L flag,
and it is required. I’ve tried changing the order of libraries on
the command line, and also tried “-a,archive_shared” flags on the
linker to give static libs a higher preference than shared. I’ve
also tried temporarily removing $ORAHOME/lib from my SHLIB_PATH and
LD_LIBRARY_PATH environment variables. However, nothing I do seems to get
around this problem. Does anybody have an idea how I can link my app correctly to
avoid this problem? Does Oracle use openSSL internally (and hence the
conflict)? Has anybody had troubles with this before? If I can’t fix the linking, should I perform some
preprocessor trickery to put the OpenSSL bn.h functions in some namespace, or
would the Oracle/OpenSSL overlap be so great that this will be too hard and
encompass more than just the functions in bn.h? Any help or hints would be much appreciated, cheers,
