and your build will miserably fail
To fix that, you need to edit uwsgiconfig.py, find following line:
self.cflags = ['-O2', '-Wall', '-Werror', '-D_LARGEFILE_SOURCE', '-D_FILE_OFFSET_BITS=64'] + os.environ.get("CFLAGS", "").split()
and remove -Werror
In case you want to do it automatically by your deployment scripts, here is a small sed snippet:
sed -ie "s#'-Werror',##g" uwsgiconfig.py
After patching uwsgiconfig.py you’re ready to rock&roll:
python uwsgiconfig.py --build myproject
