Install error on Debian about pysubnettree

[jsiwek]

A guess is that some mismatch in your environment is causing that flag to be added (I don't find "-fstack-protector-strong" anywhere in the pysubnettree sources). Is it set in CFLAGS or CXXFLAGS in your environment (check output of env command) ?

Or do you happen to use or have custom compiler or python versions on your system? E.g. if python was built with a newer compiler version that did support -fstack-protector-strong, but it's now using an older compiler here, that might be a reason.

Trying this might be a way to override compile flags:

BASECFLAGS="" OPT="" CFLAGS="" CXXFLAGS="" python2.7 setup.py install

Another idea would be to check the output of:

python2.7 -c "import sysconfig; print sysconfig.get_config_vars()"

and see if -fstack-protector-strong shows up anywhere, then try manually overriding it by putting your own code in setup.py.
