Installation documentation outdated?

[gjtimmerman]

If I follow the installation documentation I seem to have installed a deprecated version.

[AlexDenisov]

Could you tell a bit more? Which OS and which version are you trying to install?

Hi Alex,
I am using mac os 11.01 and trying to use brew to install Mull:
brew install mull-project/mull/mull-stable
However, I got this error message:

Could you please help me?

I use Ubuntu 18.04 and I used the installation documentation to install mull:

curl -1sLf 'https://dl.cloudsmith.io/public/mull-project/mull-stable/setup.deb.sh' | sudo -E bash
sudo apt-get update
sudo apt-get install mull

It installed 'mull-cxx-9' and when I executed:
'mull-cxx-9 --version' it said that this version was deprecated.

@RainyTong unfortunately, homebrew packages are outdated. Currently, I can only suggest downloading the packages directly, for example from here.

@gjtimmerman the tool itself (mull-cxx-X) is deprecated, but the package comes with mull-ir-frontend-9.
Once you install mull-9 (not mull), then you can check where the files are:

$ dpkg-query -L mull-9
/usr
/usr/bin
/usr/bin/mull-cxx-9
/usr/bin/mull-runner-9
/usr/lib
/usr/lib/mull-ir-frontend-9

@RainyTong I added a ticket for your issue #957

Thank you for your quick response and help! @AlexDenisov

@AlexDenisov : so if I understand it correctly: the tool I used to check whether the installation was correct that printed a deprecation message with a link to other releases, should not give me the idea that I installed an outdated version?
My suggestion is to let users check the installation in another way and not by using a deprecated tool.

@AlexDenisov : a further question about mull-9: as I understand it, that is the latest stable version, right? Should I also use clang-9 with it or can I use any version of clang with it?

You are right! I'll update the docs!

This is a bit confusing, but the latest version of Mull is 0.15.0 (as of today). The -9 (or any other number) indicates version of Clang/LLVM this version is built for.
So you should be using clang-9 with mull-9, clang-10 with mull-10, etc.

Now I see that the installation doc is broken, I can suggest looking at the tutorial instead https://mull.readthedocs.io/en/0.15.0/tutorials/HelloWorld.html
It was certainly updated.

@gjtimmerman the installation doc was indeed outdated. The fixed version is live: https://mull.readthedocs.io/en/latest/Installation.html
