[OSX][64-bit] Missing symbols of libgphobos2.a

Dan Sănduleac avatarDan Sănduleac created an issue

Some symbols are missing, which raises linking errors when I use gdc (under Mac OS X) - linking.txt.

See the output of nm libgphobos2.a attached (as the rightmost missing_symbols.txt.. apparently can't delete/rename attachments.

Since then I've recompiled with gcc-4.5.3, but am facing the same issues. I'm also attaching exactly the symbols reported as missing by ld (as the leftmost missing_symbols.txt).

# examples for one of the missing symbols

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
