RE: Compiling on a Mac
From: Larry Bugbee The source for incremental_send isn't in the book anywhere that I've seen. I'm using the first edition (June 2002). My code does call incremental_send, and the code I'm trying to compile is the example code provided in the book itself (in chapter 6 - see example 6-4). The book provides the code for incremental_encrypt as well as incremental_finish, so my assumption is that it is a method included in the bowels of the libraries provided. Are you saying that this is a method that I must construct myself? The book doesn't say that, so my assumption is that it is provided. I have run into books that claim to be good but the publisher leaves out critical stuff. Go to the publisher's site and look for errata and downloadable source files. Good advice in general, but not relevant in this case. The discussion of the example in the book says of incremental_send which is simply a stub, but it can place those blocks currently encrypted on the network. It's just a place-holder in the example, indicating 'this is where you do something with the data you've encrypted'. It's up to the developer to provide the functionality. __ OpenSSL Project http://www.openssl.org User Support Mailing Listopenssl-users@openssl.org Automated List Manager [EMAIL PROTECTED]

Re: Compiling on a Mac
Hi David,
I'm down to symbol not defined for one item - incremental_send (and I can't
find what file this is supposed to be in).
I re-installed to /usr/include/openssl and used --prefix=/usr/include and
--openssldir=/usr/include/openssl
I'm trying to compile now with -lssl -lcrypto -L/usr/include/openssl
I believe -lssl tried linking to a legacy version of openssl (I saw a thread
on this on the openssl website FAQ section).
I'm using the examples in the O'Reilly OpenSSL book. I've attached the file
I'm using for your review.
Here's what I'm getting now when I try and compile - this appears to be the
only error.
Undefined symbols:

So adding /usr/include/openssl to the includes will only help if you
installed the opensslconf.h file as

sense.
Also, what file did '-lssl' actually wind up linking to? Was it the file

Compiling on a Mac
Hi everyone, I'm having a build issue on a Mac (10.5) that resembles the problem mentioned on the FAQ page: http://www.openssl.org/support/faq.html#BUILD9 I searched my HDD for a 'PROBLEMS' file and the only one I found was for emacs. Doesn't look like what I need. The issue I'm seeing is when compiling: mac# openssl version OpenSSL 0.9.7l 28 Sep 2006 mac# gcc blowfish.c -o blowfish ... Undefined symbols: _incremental_send, referenced from: _incremental_encrypt in ccbqFUEC.o _incremental_finish in ccbqFUEC.o _EVP_DecryptUpdate, referenced from: _decrypt_example in ccbqFUEC.o _EVP_EncryptInit, referenced from: _setup_for_encryption in ccbqFUEC.o _main in ccbqFUEC.o _EVP_bf_cbc, referenced from: _setup_for_encryption in ccbqFUEC.o _setup_for_decryption in ccbqFUEC.o _main in ccbqFUEC.o _main in ccbqFUEC.o _RAND_pseudo_bytes, referenced from: _select_random_iv in ccbqFUEC.o _EVP_DecryptFinal, referenced from: _main in ccbqFUEC.o _EVP_EncryptUpdate, referenced from: _encrypt_example in ccbqFUEC.o _encrypt_example in ccbqFUEC.o _incremental_encrypt in ccbqFUEC.o _EVP_DecryptInit, referenced from: _setup_for_decryption in ccbqFUEC.o _main in ccbqFUEC.o _RAND_bytes, referenced from: _select_random_key in ccbqFUEC.o _EVP_EncryptFinal, referenced from: _encrypt_example in ccbqFUEC.o _incremental_finish in ccbqFUEC.o _seed_prng, referenced from: _setup_for_encryption in ccbqFUEC.o _main in ccbqFUEC.o ld: symbol(s) not found collect2: ld returned 1 exit status Does anyone have any pointers or tips on how to rectify this?

blowfish.c is a progam I wrote which contained a series of methods for initializing, encrypting, and decrypting.

Re: Problems compiling OpenSSL for Mac OS X Server.
From: Mark Morrill [EMAIL PROTECTED] I'm sorry, but I did respond to that kind of question some time ago. The problem is, I think no-one in the development team has access to any MacOS X machine, so checking things out is a bit of a problem. The error at hand is very easily fixed if there's a way to identify MacOS X through some C macro. OpenBSD, for example, is identifiable through the macro __OpenBSD__. Is there such a thing for MacOS X? Please help us find that kind of information, and in turn, we can help you fix the problem! Another way to help the development team is to give someone in the team an account on a MacOS X machine. The only requirement is that it's accessible remotely. I did mention this in my response as well. mark I asked the same thing some time ago, but didn't get any help :( mark I've just posted the question on [EMAIL PROTECTED] mark and [EMAIL PROTECTED]. mark mark I'm hoping for better luck from those lists... mark mark If I get any answers, I'll post them here and send them to you. mark mark Mark mark mark mark on 11/27/00 15:40, steve stout at [EMAIL PROTECTED] wrote: mark mark I am trying to compile OpenSSL 0.9.6 on Mac OS X Server 1.2 and I keep mark getting the following error when I try to make it. mark mark /usr/bin/ld: Undefined symbols: mark _ftime mark make[1]: *** [openssl] Error 1 mark make: *** [all] Error 1 mark mark mark Has anyone successfully compiled OpenSSL for OSX Server 1.2? mark If so, please help. -- Richard Levitte \ Spannvägen 38, II \ [EMAIL PROTECTED] Chairman@Stacken \ S-168 35 BROMMA \ T: +46-8-26 52 47 Redakteur@Stacken \ SWEDEN \ or +46-709-50 36 10 Procurator Odiosus Ex Infernis-- [EMAIL PROTECTED] Member of the OpenSSL development team: http://www.openssl.org/ Software Engineer, Celo Communications: http://www.celocom.com/ Unsolicited commercial email is subject to an archival fee of $400.

Is there such a thing for MacOS X? Please help us find that kind of information, and in turn, we can help you fix the problem! I worked through this problem just this week. There's one line in apps/speed.c that needs to have the __APPLE__ macro added to it. This isn't the sanctioned macro to use for identifying MacOSX or MacOSXServer operating systems, but it is expedient. In line 90 of speed.c, you need to add " !defined(__APPLE__)" to the list of conditionals that determine whether to define the TIMEB symbol. #if defined(__FreeBSD__) # define USE_TOD #elif !defined(MSDOS) (!defined(VMS) || defined(__DECC)) # define TIMES #endif #if !defined(_UNICOS) !defined(__OpenBSD__) !defined(sgi) !defined(__Fr eeBSD__) !(defined(__bsdi) || defined(__bsdi__)) !defined(_AIX) !define d(MPE) !defined(__APPLE__) # define TIMEB #endif The recommended way to deal with this on Mac OS is to define your symbol identifying the OS. Inventing a symbol like "__MACOSX__", make the edit to apps/speed.c described above, substituting "__MACOSX__" for "__APPLE__". Then run config again, with these parameters: ./config no-threads -D__MACOSX__ Hope this helps. I have OpenSSL 0.9.6 running on my MOSX box, so it should work for you too.

Id like to get current OpenSSL, it ships with 0.9.5a. If so how do you get it to build and install in the 'OS X Way', i.e. stuff in Frameworks etc? Cheers, Andrew PS.
