prepare.sh fails

[DevLorin]

Hello

So I tried following steps:

1. Installed a clean Ubuntu 23.10 into a VirtualBox (7.0.12) environment.
2. Created a user "rb" as instructed and made it root.
3. Cloned renpy-build and hit ./prepare.sh

and got this:

(prepare.sh, line 14) E: Unable to locate package python2-dev

Is python2-dev still needed or is this only for building with python version 2? After deleting python2-dev in prepare.sh, I have the following:

(prepare.sh, line 45)

Is it possible to use llvm 16 or 17?

(nightly/python.sh, line 17)

After changing line 18 to:

sudo python3 setup.py install headers This is our next output:

Am I missing something here? Thanks.

python2-dev is still needed.

You might want to make sure the universe and multiverse repositories are enabled.

AFAIK, Python 2 is not available in Ubuntu 23.04 and later so the python2-dev cannot be installed. Maybe it is available through ESM/Ubuntu Pro?

Building Ren'Py from a fresh Ubuntu 22.04 docker container worked for me, after installing the libharfbuzz-dev and bc packages. I've only tried building the web3 version though.

[renpytom]

Ah, okay. I have it here, though we may be able to live without it. That being said, it might make sense to just stick to 22.04 until we drop Python 2 support entirely, in mid 2024.

[DevLorin]

@Kassy2048 Thanks for the advice. I attempted the build process on a fresh Ubuntu 22.04 VM. I installed the libharfbuzz-dev and bc packages.

However I encountered an error related to the absence of the Live2DCubismCore.h file:

/home/rb/renpy-build/renpy/gen3-static/renpy.gl2.live2dmodel.c:751:10: fatal error: 'Live2DCubismCore.h' file not found

I tried to build for Windows but after trying for the Web platform, I noticed that the same error occurs. Did you also encouter this problem? I saved the Cubism SDK in /renpy-build/tars as stated in the renpy-build/tars/README.rst before running ./build.py. (CubismSdkForNative-4-r.7.zip)

[Kassy2048]

@renpytom I agree, better stick to Ubuntu 22.04 as it's the latst version to support Python 2 and it's a LTS so it should be maintained until 2027. It is possible to install Python 2 on 23.10 manually or using tools like pyenv, but that will increase build time ofc.

@LorinDesch You need to download the exact same version as renpy-build expects, which is "CubismSdkForNative-4-r.6.2.zip".

For the records, here are the commands I've used to build Ren'Py on docker (first command is from the host):

docker run --interactive --tty --name renpy_build ubuntu:22.04 bash

apt update && apt install git sudo lsb-release wget software-properties-common gnupg nano
apt install libharfbuzz-dev bc
mkdir renpy-dev
cd /renpy-dev
git clone https://github.com/renpy/renpy-build.git
cd renpy-build
./prepare.sh
cd tars
wget 'https://cubism.live2d.com/sdk-native/bin/CubismSdkForNative-4-r.6.2.zip'
cd ..
. tmp/virtualenv.py3/bin/activate
./build.py --platform web

You may want to change the renpy-build repository URL to your own, as well as the URLs in "nightly/git.sh" before executing "prepare.sh".

[DevLorin]

Thanks for your assistance. Unfortunately, I've encountered new errors (still building for Windows). The specific error I'm facing is as follows:

Traceback (most recent call last):
  File "/home/rb/renpy-build/./build.py", line 231, in <module>
    main()
  File "/home/rb/renpy-build/./build.py", line 227, in main

    self.function(context)
  File "/home/rb/renpy-build/tasks/pythonlib.py", line 532, in python3
    raise Exception(f"Unused rules: {rules - used_rules}")
Exception: Unused rules: {'steamapi'}

I noticed that line 527 in renpy-build/tasks/python.lib is commented out:

# used_rules.add("steamapi")


if rules - used_rules:
    if c.platform != "web":
        raise Exception(f"Unused rules: {rules - used_rules}")

According to renpy-build/tars/README.rst, Ren'Py should build without Steamworks. Is it safe to comment out this line? I tried doing that, but it resulted in a linker error:

Regarding the last one - https://github.com/renpy/renpy-build/commit/b223a61144a2423ebfeaa1b38037b72dc2c21750 Regarding steamapi - if I'm correct, you need to add the SDK, which is listed in the README.

Ah, okay. I have it here, though we may be able to live without it. That being said, it might make sense to just stick to 22.04 until we drop Python 2 support entirely, in mid 2024.

Perhaps python2-dev is no longer needed, since the build scripts are all run through python3, and hostpython2 manually builds the python2 used by Renpy 7.
