Build failed. Unable to generate C code using cython3

After using build.sh command , i got the following output in terminal (I'm using Ubuntu 18.04) :

@ali-oem

• delete this directory mkdir: cannot create directory ‘build’: File exists
• and then reinstall

error is saying that cython3: not found, I think the above skip is skipping this installation as well, so you try a clean install once again.

What should I delete?

Same here.

The problem is the lack of Python3.8 on your operating systems. When using gcc in the build.sh , the script explicitly includes header files from /usr/include/python3.8. Installing Python3.8 may solve the issue, however I have not yet tried it.

I had the same problem, was fixed after I first deleted my old VM and installed a whole new kali VM and sudo apt install cython3

Prior to deleting my old machine, sudo apt install cython3 did not fix it for some reason even though I was using python 3.8.

[nonetrix]

I am having this issue on arch however reinstalling doesn't do anything

[nonetrix]

it is just called cython and not cython3 for me editing bulid.sh worked

[tykavanaugh]

It worked after I installed cython using apt instead of pip or conda on Ubuntu, Mint and Kali.

I have no tried again on base debian.

[nonetrix]

Honestly it should check for cython and cython3 in /bin and use which ever one is in there

Сработало да!
Но теперь имея это:
mkdir: cannot create directory ‘build’: File exists Compiling /home/ali/torghost/torghost.py /usr/local/lib/python3.6/dist-packages/Cython/Compiler/Main.py:369: FutureWarning: Cython directive 'language_level' not set, using 2 for now (Py2).

Тоже самое.

Проблема в том, что в ваших операционных системах отсутствует Python3.8. При использовании gcc в build.sh скрипт явно включает файлы заголовков из /usr/include/python3.8. Установка Python3.8 может решить проблему, но я еще не пробовал.

The problem is solved by changing the build.sh file
You need to see what version of python is installed.
Most likely version 3.9 is installed.
If so, then you need to adjust the following line build.sh

gcc -Os -I /usr/include/python3.9 -o torghost torghost.c -lpython3.9 -lpthread -lm -lutil -ldl
