OpenSSL build script fails when run as a 'run script' phase within Xcode (succeeds outside of Xcode)

Question

I'm attempting to run a script to build OpenSSL for iOS (armv6, armv7 and i386) as a 'run script' phase in Xcode.

The script builds successfully when run from the command line as a stand alone script. The result is a compiled libcrypto.a, libssl.a and include directory with the headers.

However, when I run the script as a run script phase in Xcode, it gets towards the end of make and errors out stating that it couldn't find any symbols referenced from libcrypto.

        shlib_target="bsd-gcc-shared"; \
    fi; \

Undefined symbols for architecture i386:
  "_ENGINE_load_gost", referenced from:
      _ENGINE_load_builtin_engines in libcrypto.a(eng_all.o)

collect2: ld returned 1 exit status

I'm almost certain that this is a paths issue, but I can't figure out how to tell Xcode (or the script) which paths to use.

The script, available here, needed to be modified to account for the recent changes to the location of the developer tools with Xcode 4.3 (namely the fact that Developer/ is no longer at the root, but actually inside Xcode.app).

Here's the script for question completeness:

Answer 1

Even though this is an older post, I think the problem still persist. But I think I found a very simple solution. Just add the following line to the Build-Script, before "Configure" or "make" is called:

export COMMAND_MODE=unix2003

This should do the trick.

Answer 2

It's been logged as an issue on openssl.

Adjust your configure line:

./Configure darwin64-x86_64-cc zlib no-asm no-krb5 shared
