stunnel on QNX   
Can anyone share any information about stunnel (SSL Proxy) support for QNX? I have reason to believe that this 
application is supported on QNX but I have been so far unable to find any additional resources about it running on QNX. 


I have downloaded the source but have yet to get the 6.4.1 toolchain to successfully cross compile (win32 x86-> qnx ppc)
--has anyone successfully done this?

Personally I'm not familiar with stunnel but what I just read about it 
says it relies on openssl, which QNX does have.

Yes, I do it all the time :-)

If you're using the "latest and greatest" code, you will have to look at 
the posts in the build forum...

Is it Owen or Mike? :-)

Re: stunnel on QNX   
Either Mike/Owen one is fine--yes, I've also been able to cross-compile some other things easily but as I was unable to 
do so with stunnel, I was wondering if there was any gotchas I should have been looking for before I start getting my 
hands dirty.

Well, I haven't even seen the stunnel source code, never mind a binary 
so I couldn't tell you :-) You should check out pkgsrc, maybe there's 
something there...

Good luck!

Re: stunnel on QNX   
Got it ported now, works just fine.

Only one question: was the ssl library in the 6.4.1 SDK not compiled with pthread support? If so, why?

Great :-)

I'm not sure what you mean by that. Note: pthreads are part of libc.

libcrypto and libssl get compiled with -DOPENSSL_THREADS defined.

Yeah, so Owen, why do you say openssl is without pthread support?

It's also defined in the shipped /usr/include/openssl/opensslconf.h.

Re: stunnel on QNX   
Yes, I was just getting to opensslconf.h, lots of replies :-).

If I compile stunnel with -DUSE_PTHREAD, the following #define error gets hit:

#define OPENSSL_THREAD_DEFINES
#include <openssl/opensslconf.h>
#if !defined(OPENSSL_THREADS) && defined(USE_PTHREAD)
#error OpenSSL library compiled without thread support
#endif /* !OPENSSL_THREADS && USE_PTHREAD */

Looking at my <openssl/opensslconf.h>, versioned at:

__SRCVERSION( "$URL: http://community.qnx.com/svn/repos/core_networking/branches/6.4.1/trunk/lib/crypto/openssl/
opensslconf.h $ $Rev: 972 $" )

there is no OPENSSL_THREADS defined. This is a standard 6.4.1 SDK install, did I miss a patch?

Re: stunnel on QNX   
Any further thoughts? From your replies, it would appear my version of opensslconf.h is inconsistent with what was 
intended to be in 6.4.1.

I was looking at the 6.5 stuff.  It's 'fixed' therein.
