Hi all:

I just tried to create a Sage 4.6 sandbox to start writing patches with but got some apparently fatal errors running Mac OS 10.6 with the latest version of Xcode installed. Any suggestions?

After cloning, if you change any Sage library files and want to rebuild
the html version of the reference manual, use the command
    sage -docbuild reference html
(after running 'sage -b').

Note: if *before* cloning, you have changed any Sage library files
without rebuilding the reference manual, then after cloning, you
will need to touch those files again if you want the changes
to be incorporated into the reference manual.

Okay, this is progress. I've seen this ___emutls_get_address problem myself before. It's picking up a library that it shouldn't, namely /usr/local/lib/libstdc++.6.dylib: I don't have any such library there, and I compile in both C and C++ all the time; those libraries live in /usr/lib. It's quite likely it's picking up an incompatible version and not finding the functions, because of a library path ordering issue so that /usr/local/lib is dominating /usr/lib (which is often what you want).

First, for information purposes: could you confirm that you have libstdc++ in /usr/lib via ls -la /usr/lib/libstdc*? You should have the library itself (6.0.9, I think) and an unversioned symbolic link pointing to it. Then use "file /usr/local/lib/libstdc++.6.dylib" (or whatever the name is: I don't have the file so it's easy for me to have typos!) to look at the architecture for that one.

Second, for an attempt at an actual solution: try moving /usr/local to /usr/local_tmp and recompiling. There's nothing in /usr/local that you should need to compile Sage -- and I think the existence of this alternate library from one of the SDK packages is causing the problems.

(BTW, I don't think there's anyone here called Miles. There's Niles, and there's me, who wrote the reply, but that's it. :^)

I'm running OS X 10.6.5 and Xcode 3.2.5 (1760). I just downloaded a fresh install [sage-4.6-OSX-64bit-10.6-i386-Darwin.dmg], copied the volume into /Applications in the usual way, and installed sage-mode. Cloning worked for me:

localhost:sage mcneil$ ./sage -clone local_mod

[etc]

I think the key is figuring out why it can't find your stdlib.h. The corresponding line in pari.h is #include <stdlib.h>, so it should pick up from the environment. By inserting garbage into /usr/include/stdlib.h and forcing a rebuild I confirmed that's the one it's using for me (and not one of the SDK versions it noticed). Could you check the existence and permissions of /usr/include/stdlib.h as well as your environment variables? What include paths does your gcc use?

Woops, sorry Niles. And thanks DSM for your quick reply. Following your instructions i get the following.

raichev@wujarch-l~> ls -la /usr/lib/libstdc* -rw-r--r-- 1 root wheel 15400372 25 Jun 2010 /usr/lib/libstdc++-static.a -rwxr-xr-x 1 root wheel 2439888 19 May 2009 /usr/lib/libstdc++.6.0.9.dylib* lrwxr-xr-x 1 root wheel 21 4 Sep 2009 /usr/lib/libstdc++.6.dylib@ -> libstdc++.6.0.9.dylib

raichev@wujarch-l~> file /usr/local/lib/libstdc++.6.dylib /usr/local/lib/libstdc++.6.dylib: Mach-O 64-bit dynamically linked shared library x86_64

I moved /usr/local to /usr/local_temp, tried cloning again, and 22m22.782s later... It works! Hooray! Thanks Niles and DSM. Now i can get back to contributing code to Sage.

Oh, when can i or should i move /usr/local_temp back to /usr/local?

Okay, glad it worked! As for restoring /usr/local, that's up to you, but it's quite possible it'll cause trouble for something else (google for ___emutls_get_address to see lots of non-Sage related build problems it causes). Now that it's pretty clear what the problem is, you might consider just removing/renaming the incorrect libraries. And don't forget to accept the answer that works [i.e. the answer recommending renaming /usr/local], er.. so that future people can find it easier, yeah, that's it. ;^)

I'm glad it's working too; thanks @DSM :) And Alex, don't forget to mark that answer "accepted" (the little check mark).

Thanks again, folks. This site is great! DSM, are you saying that i can probably move /usr/local_temp back to /usr/local without problems if i rename or remove /usr/local/lib/libstdc++.6.dylib?

araichev gravatar imagearaichev ( 2011-01-11 08:26:58 -0600 )edit

Yep. For example, I have a /usr/local directory with various bits. But although that library is clearly causing issues, I don't know if there's an incompatible something else (whether in /usr/local/lib or in /usr/local/include) which may cause problems, so while I figure it's probably necessary I don't know if it's enough. Shouldn't take too long to test, though.

Too much text to post as a comment and so i'm posting as an answer, which it is not.

Thanks for your reply, Miles. I reinstalled Xcode 3.2.5 and Sage 4.6 and tried again. I got farther this time but ran into import errors again. Before i show them to you, here are my stdlib.h permissions and environment variables after i ran './sage -clone dabble'.
