Revision history [back]

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'.

Now for the clone attempt.

raichev@wujarch-l/Applications/sage> ./sage -clone dabble

Now cloning the current Sage library branch... hg clone sage sage-dabble updating working directory 2339 files updated, 0 files merged, 0 files removed, 0 files unresolved Copying over all Cython auto-generated .c, .cpp and .h files... Copying over build directory... Copying over all auto-generated reference manual .rst files... Copying over documentation output... Building sage-dabble... sage -b dabble

[all normal stuff and then...]

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.
