Compiling on Leopard & Snow Leopard

[Scott F. Comstock]

Has anyone had luck compiling Cryptlib (static or dynamic) on Leopard or
Snow Leopard?

I can make it compile, however I get a trap during the tests. I can post the fixes for debugging (there's at least one define that needs to be changed), but I think some more in depth work will have to be done to fix it for snow leopard. Static compilation doesn't work on leopard, but dynamic does.

I build it on... hmm, I can't get to the machine at the moment so I can't
check the version but I'm pretty sure it's 10.5.  If someone can give me SSH
access to a 10.6 box I'll get it running on that.

(There was an incorrect define in the last release in osconfig.h for B_ENDIAN,
but apart from that it should build OK, at least on non-10.6).

Peter.

3.3.2 compiled out of the box last April on 10.5 i386 (recent version  
of 10.5 at that time).
Build log available on request.
Test completed with:
---
All tests concluded successfully.

Not yet.  I toyed with this for an hour or so over the weekend, but  
don't have a working version yet (though it's compiling now, so that's  
progress :). So far:

crypt/osconfig.h has a second "#define B_ENDIAN" after the #if/#else  
for __ppc__ which kind of moots the point of the attempted detection.

Also, it appears that SL needs a Darwin linking rule in getlibs.sh to  
link to libresolv.

That's as far as I got before real life intervened (read: I went to  
the art museum).

I can't give you access, but here's what I get:

stovetop:cryptlib-3.3.3 tmiller$ make testlib
Undefined symbols:
   "_res_9_dn_skipname", referenced from:
       _findHostInfo in libcl.a(dns_srv.o)
       _findHostInfo in libcl.a(dns_srv.o)
       _findHostInfo in libcl.a(dns_srv.o)
   "_res_9_query", referenced from:
       _findHostInfo in libcl.a(dns_srv.o)
   "_res_9_dn_expand", referenced from:
       _findHostInfo in libcl.a(dns_srv.o)
ld: symbol(s) not found
collect2: ld returned 1 exit status
make: *** [testlib] Error 1

Adding a Darwin stanza to getlibs.sh with -lresolv didn't seem to  
work, but I could be mistaken on how your build system hangs together.

Ah, that's an easy one, to fix it just undefine USE_DNSSRV in misc/config.h.

Okay, now I get:

stovetop:cryptlib-3.3.3 tmiller$ make testlib
stovetop:cryptlib-3.3.3 tmiller$ ./testlib
Trace/BPT trap

This is with a debug build.

So a preliminary update, the problem is due to a SIGTRAP in dlopen(), an
(apparent) bug introduced in Snow Leopard.  Others have found this as well,
see e.g. http://openradar.appspot.com/7209349.

It's definitely a bug in dlopen() in OS X 10.6.  To work around this, at line
41 (or thereabouts) of cryptlib.c, add:

#undef USE_THREADS

and rebuild.  This will disable the use of dlopen() from a worker thread.

Peter.
