uWSGI 1.1.2 - Symbol not found problem #11705

Closed rochacon closed 12 years ago

rochacon commented 12 years ago

Hi. After upgrading the uWSGI to the last version, 1.1.2 I'm receiving this 

~ $ uwsgi --version
dyld: Symbol not found: _environ
  Referenced from: /usr/local/lib/libpython2.7.dylib
  Expected in: dynamic lookup

Trace/BPT trap: 5

The build process shows no error:

~ $ brew install uwsgi
==> Downloading http://projects.unbit.it/downloads/uwsgi-1.1.2.tar.gz
Already downloaded: /Users/rochacon/Library/Caches/Homebrew/uwsgi-1.1.2.tar.gz
==> python uwsgiconfig.py --build
/usr/local/Cellar/uwsgi/1.1.2: 5 files, 488K, built in 11 seconds

I'm using the latest Python version: 2.7.3, also installed with Homebrew.

@adamv Fink is applying a patch for _environ access in python (it's buried in this huge patchfile):

If I remember from previous similar cases, the "fix" is to patch uwsgi, not Python, but it has been a while. But I could be wrong. We had been patching around _environ in some cases but stopped having to.

Using this line:

CFLAGS="-Os -w -pipe -march=core2 -msse4 -arch x86_64" LDFLAGS="-arch x86_64" /usr/local/bin/pip install uwsgi

Compiled and installed uWSGI without any errors. How can I see the flags that Homebrew is using? Do Homebrew really need to patch anything in here?

This is the pip install output:

$ CFLAGS="-Os -w -pipe -march=core2 -msse4 -arch x86_64" LDFLAGS="-arch x86_64" /usr/local/bin/pip install uwsgi

BTW, I only have installed the Apple Command Line Tools.

If it can be easily installed from pip then it should probably be removed from Homebrew anyway.

Though I guess it's not really python software so maybe not.

jacknagel commented 12 years ago

If you can build it from source with the same CFLAGS then it must be a stripping issue.

I'll try with skip_clean and see if it works.

jacknagel commented 12 years ago

Yeah that was it. Fixed in ed5402b

Cool! Thanks!
