I have the same issue. Does anyone has a solution for this?

[PatrickPromitzer]

Hi, I had this error before, and fixed it. You can try using

export CPLUS_INCLUDE_PATH="$CPLUS_INCLUDE_PATH:/usr/bin/python3.8"

(I added it in my .bashrc) You may have to change the python version in the export.

Another part I changed was adding

#include <stdint.h>

To the script that gives the error. For my part, it was in "LibCarla/source/Carla/client/FileTransfer.h" I believe the "RegxParser.cpp.o" gives the error, but you probably need to find if that it the root of it.

I am not sure if it fixes your problem, but I read that in an version update of a package the int and uint values changed (different name?) and this it raising an error.

I suggest you to try install:

sudo apt install libc6

And the run make again.

Okay so I found out it was solved in #5209. It appears that this is completly not connected to the missing libraries. You have to switch name of the folder /usr/include/c++/v1 to something else (I changed it to v1.1) and it works.

Thank you for the comment! I solved my problem!
