how to check which compiler was used to build Python
compiler-construction, python
Solution
Easiest way in the REPL, you have it in `sys.version`:
>>> import sys
>>> print(sys.version)
3.7.0 (default, Jul 24 2018, 19:03:02)
[GCC 8.1.0]
It should also usually tell you when you start the interactive interpreter:
$ python3
Python 3.7.0 (default, Jul 24 2018, 19:03:02)
[GCC 8.1.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>
Easiest way at the shell: pass the command line option `-V` twice to print info about the build. It seems this is a new feature and is missing in Python 2.
$ python3 -VV
Python 3.7.0 (default, Jul 24 2018, 19:03:02)
[GCC 8.1.0]
Problem
Is there a way to tell which compiler was used to build a `Python` install on a specific linux machine? I tried using `ldd` on the `Python` dynamic libraries [1], but I didn't manage to understand if it was compiled with `gcc` or Intel compiler. [1] ``` $ ldd libpython2.7.so.1.0 linux-vdso.so.1 => (0x00007fff4a5ff000) libpthread.so.0 => /lib64/libpthread.so.0 (0x00002ab8de8ae000) libdl.so.2 => /lib64/libdl.so.2 (0x00002ab8deac9000) libutil.so.1 => /lib64/libutil.so.1 (0x00002ab8deccd000) libm.so.6 => /lib64/libm.so.6 (0x00002ab8deed1000) libc.so.6 => /lib64/libc.so.6 (0x00002ab8df154000) /lib64/ld-linux-x86-64.so.2 (0x0000003b9a400000) ```
