how can build , install c program debugging symbols on os x?

i'm trying build (mutt) debugging symbols on os x, me track down crash. i'm following homebrew formula mutt in build process. no matter try, resulting binary has no debugging symbols. build cflags='-g -o0' (after having tried default '-g -o2' in makefile). can see when see make output go using these flags should be, , don't see strip or install -s invocations; resulting binary has no debugging symbols, seen trying run in gdb or lldb, or running dsymutil on it.

i'm trying understand the valgrind instructions on matter; basically, linker on os x doesn't put debug symbols exist in object files linked result -- read saying have run dsymutil on linked result, i'm little unsure whether automatically pulls in symbols object files, or if there's way need specify them.

and if knew how use dsymutil here, don't see there debug symbols in of .o files.

finally, i'm wondering if "proper" installation, once got debugging symbols binary, copy .dsym directory /usr/local/bin along mutt; or if go somewhere else. know in debian-based systems can install debuggable versions of libraries using package manager, don't know if it's best practice (or practice that's common) install things debug symbols in os x. if nothing else, can run debuggable binary build directory, doesn't seem big deal.

i've tried building gcc , clang, same disappointing results.

i'm new python/django , created simple django website using pycharm. site works fine running on computer, i'm lost when comes taking site onto host (dreamhost). i'm able upload files correct directories fine, , believe made correct changes database on mysql. i'm not sure go there though. right now, page shows files rather site. direction appreciated. much! you should not run django application using python manage.py runserver on production. how run application on django depends on server (apache, nginx) want use for apache - https://docs.djangoproject.com/en/1.10/howto/deployment/wsgi/modwsgi/ for nginx - https://www.digitalocean.com/community/tutorials/how-to-serve-django-applications-with-uwsgi-and-nginx-on-ubuntu-14-04 the mysql database should, of course, exist , have correct credentials. or, if choose use sqlite, file should accessible, readable , writable www-user (may different depending on linux distributive)
