Is there a way to tell if python was configured and compiled with "--with-threads --enable-shared"?

Question

This is for Python 2.6.6 on Debian Squeeez. I'm trying to find out if the binaries shipped with debian were configured with the flags of:

--with-threads --enable-shared

as if they were not I will need to compile and install from source myself.

Try parsing info from pyconfig.h? This file is generated during the compile time and is platform specific. Not sure if it has all the flags, though :( Also running python -v might reveal some information. — Mikko Ohtamaa, Feb 08 '12 at 13:02
if you guys using newest version of python check this https://stackoverflow.com/questions/23201498/how-to-check-if-python3-was-built-with-enable-shared and this https://stackoverflow.com/questions/10192758/how-to-get-the-list-of-options-that-python-was-compiled-with — buncis, Jul 28 '21 at 20:01

--with-threads (which is the default) will mean Python supports threading, which will mean import thread will work. An easy way to test this is with python$version -m threading

--enable-shared will mean Python comes with a libpython$version.so file, installed in $prefix/lib (alongside the python$version directory, not inside it.) The easiest thing to do is to look if that file is there -- assuming you want to know because you need to use this libpython shared library. If you actually need to know if the python$version binary uses this shared library, ldd will tell you that. I make that distinction because on Debian, /usr/lib/python$version.so will exist even though /usr/bin/python$version is statically linked.

And by `import thread` works, you mean it won't throw an `ImportError`, which you can test for in from Python code. — Martijn Pieters, Dec 05 '13 at 16:09
