3. You undefine PY_NO_RTLD_GLOBAL in auto/config.h after configuration. This
may crash Vim though.
+ *E880*
+ Raising SystemExit exception in python isn't endorsed way to quit vim, use: >
+ :py vim.command("qall!")
+ <
+
*has-python*
You can test what Python version is available with: >
if has('python')
