I am using OpenSSL on Linux in a shared library environment (./config
shared).
I am trying to load support for the Broadcom uBSec engine. Here is a
test program:
int main (int argc, char *argv[])
{ ENGINE *Engine;
SSL_library_init();
SSL_load_error_strings();
OpenSSL_add_all_algorithms();
ENGINE_load_ubsec();
// See if we can find the ubsec engine
Engine = ENGINE_by_id ("ubsec");
if (Engine)
printf ("ENGINE_by_id() found uBSec at %p.\n", Engine);
else
printf ("ENGINE_by_id() did not find UBSec.\n");
return (0);
}
I compile and link this file (test.c) with OpenSSL 0.9.7g:
gcc -o test test.c -I include ./libssl.so ./libcrypto.so
I run it, and it reports that it finds the uBSec engine.
I try this with OpenSSL 0.9.8 and I get a link error:
/tmp/ccuqAevP.o(.text+0x12c): In function `main':
: undefined reference to `ENGINE_load_ubsec'
collect2: ld returned 1 exit status
This symbol is in e_ubsec.c, but when I include the corresponding .o
file, I get the
same error. That's because the symbol is not defined in e_ubsec.o,
because it is
inside a conditional:
#ifdef OPENSSL_NO_DYNAMIC_ENGINE
This symbol is not defined, because I chose the shared-library
configuration.
How can I use the built-in uBSec engine in a shared-library environment?
Thanks.
