Error building with Xcode 5.1 #352

raheelahmad · 2014-04-05T05:36:47Z

I followed the README, and at the end I get a few symbols-not-found error upon building the framework. This is on Mavericks with Xcode 5.1.

Undefined symbols for architecture x86_64:
  "_EVP_aes_128_ctr", referenced from:
      _libssh2_crypt_method_aes128_ctr in libssh2.a(crypt.o)
     (maybe you meant: __libssh2_EVP_aes_128_ctr)
  "_EVP_aes_192_ctr", referenced from:
      _libssh2_crypt_method_aes192_ctr in libssh2.a(crypt.o)
     (maybe you meant: __libssh2_EVP_aes_192_ctr)

      _libssh2_crypt_method_aes256_ctr in libssh2.a(crypt.o)
     (maybe you meant: __libssh2_EVP_aes_256_ctr)

The text was updated successfully, but these errors were encountered:

+1 I'm getting the same errors in the same environment.

alanjrogers · 2014-04-11T03:14:59Z

Are you building for iOS or Mac OS ?

raheelahmad · 2014-04-11T03:16:06Z

For OS X. Tried it on multiple machines. Maybe all fresh installs are suffering from this?

alanjrogers · 2014-04-11T03:25:18Z

@raheelahmad Are you getting this error trying to build your application? or is it when you try to build the Framework directly via the xcworkspace.

raheelahmad · 2014-04-11T03:38:33Z

This is for building the ObjectiveGit framework from the project's .xcworkspace.

jspahrsummers · 2014-04-11T03:55:46Z

/cc @robrix?

raheelahmad · 2014-04-11T03:57:11Z

FWIW, tried a fresh install on another machine, with the same issue.

I could be carrying around bad luck with me though.

alanjrogers · 2014-04-11T05:01:50Z

I can't reproduce the error at all.

jlalvarez18 · 2014-04-11T11:48:23Z

I receive the same errors. Fresh install. Using the workspace. On master branch.

Have you run script/bootstrap successfully?

jlalvarez18 · 2014-04-11T13:11:43Z

Yes. All is installed. The issue has to do with libssh. Any thoughts?

Will investigate today if at all possible.

Just in case this is the full error:

Hope this helps :)

raheelahmad · 2014-04-14T04:14:15Z

My best guess is that this is because of a newer version of libssh2 which seems to be incompatible.

I have 1.4.3 according to brew list libssh2.

robrix · 2014-04-14T13:46:09Z

Curious. I have 1.4.3 as well. Sorry for the delay in looking into this, Friday spun away from me. Top of my list today tho.

robrix · 2014-04-14T14:43:12Z

I can’t reproduce this either:

robrix · 2014-04-14T14:48:42Z

@raheelahmad you called it—brew upgrade libssh2 and now I can’t build either, with the same errors.

robrix · 2014-04-14T15:12:25Z

Okay, so it looks like what’s happened is:

brew’s formula for libssh2 now depends on brew’s keg-only openssl, and therefore cannot be linked against system ssl (-lssl)
unfortunately since ssl is keg-only, we can’t just add /usr/local/lib to the library search paths since brew avoids putting libssl.a and libcrypto.a there
I was able to link correctly against the updated libssh2 by removing libssl from the target’s link build phase, and instead adding /usr/local/Cellar/openssl/1.0.1g/lib/libssl.a and /usr/local/Cellar/openssl/1.0.1g/lib/libcrypto.a to its Other Linker Flags setting
since that would necessarily break the build for everyone who hasn’t updated yet, I’m going to see if we can make this link by adding /usr/local/Cellar/openssl/1.0.1g/lib/ to the library search paths

Further bulletins as events warrant.

alanjrogers · 2014-04-29T08:59:45Z

I did a brew upgrade today, and now I'm running into this when trying to build from eed65a7.

brew list libssh says I have 1.4.3_1

alanjrogers · 2014-04-29T09:02:00Z

I've noticed that the symlinks for libcrypto.a and libssl.a point to /usr/local/opt/openssl/lib/ Which doesn't exist for me. Probably because I'm using boxen.

alanjrogers · 2014-04-29T09:04:51Z

FWIW I've fixed this in the meantime with a symlink for the opt directory.

ln -s /opt/boxen/homebrew/opt /usr/local/opt

robrix · 2014-04-29T21:34:54Z

This was fixed for the default homebrew dir, yes.

alanjrogers · 2014-04-30T01:08:28Z

@robrix It was my understanding that it would fallback to use the system libssl if the symlinks went nowhere?

robrix · 2014-04-30T23:56:41Z

It will, yes, but the problem is (IIRC) that you’ve got a libssh that can’t be linked with system libssl because system libssl lacks some of the symbols.

Interestingly, OpenSSH can now be built without dependencies on OpenSSL. I doubt that has made its way into homebrew yet, but it might make for a path out of this hell.

robrix · 2014-10-08T17:10:47Z

This just bit @haacked, and that symlink didn’t help because opt/openssl is itself a symlink to ../Cellar/openssl/1.0.1i

This got him going:

ln -s /opt/boxen/homebrew/Cellar /usr/local/Cellar
