Versions of stuff:
But when running cargo run repl, I get

Ohh wait I might have missed a step setting up llvm :thinking:
Hmm, maybe not. I forgot to do the symlink step mentioned here: https://github.com/rtfeldman/roc/blob/trunk/BUILDING_FROM_SOURCE.md
But after doing that I still get the above issue.
Hmm, also looks like the referenced llvm installation script installs llvm 13.x as opposed to 12.x mentioned in the guide. That an issue?
oooo, things are movin now. switched the symlinks to refer to 13 instead of 12.
Oh snap I'm in the repl!! :tada: :tada:
Folkert de Vries (Sep 05 2021 at 20:20):huh, llvm 13 is not even released ?! Are you using 12 or 13 now?
Richard Feldman (Sep 05 2021 at 20:28):@Matthew Griffith congrats! :smiley:
you should also be able to run the examples now! e.g. cargo run examples/hello-world/Hello.roc
Richard Feldman (Sep 05 2021 at 20:29):also cargo run edit to bring up the editor
Matthew Griffith (Sep 05 2021 at 20:30):Folkert de Vries said:
huh, llvm 13 is not even released ?! Are you using 12 or 13 now?
13 I suppose. I just switched the symlinks to point to clang-13 and llvm-as-13 and things worked.
sudo bash -c "$(wget -O - https://apt.llvm.org/llvm.sh)" installed 13
Matthew Griffith (Sep 05 2021 at 20:30):Richard Feldman said:
also
cargo run editto bring up the editor
Sweet!
Folkert de Vries (Sep 05 2021 at 20:55):well I suppose the good news is that our llvm12 -> 13 upgrade will be smooth if things just work already :smile:
Folkert de Vries (Sep 05 2021 at 20:55):release is scheduled for end of september
Oliver Schöning (Oct 21 2021 at 14:57):I have never tried to build anything from source :sweat_smile:
Just installed LLVM default via sudo apt install llvm
And cargo test gives me the following error:
...
Compiling bytemuck v1.7.2

error: build failed
Not seen this one anywhere mentioned. Unsure how to proceed
Oliver Schöning (Oct 21 2021 at 14:58):LLVM version is 12. Perhaps that is the problem?
Shritesh Bhattarai (Oct 21 2021 at 15:00):The Polly issue was painful to deal with in Zig too. IIRC LLVM themselves fixed this in subsequent releases.
Shritesh Bhattarai (Oct 21 2021 at 15:01):I think it only manifested in MacOS targets there tho.
Oliver Schöning (Oct 21 2021 at 15:04):I'm on Pop!_OS, Ubuntu based. Just trying to figure out one error at a time. Previous one, as far as I could tell, was that LLVM wasnt installed.
I also installed zig via snapd if that helps
Oliver Schöning (Oct 21 2021 at 15:05):So should I try and get a newer version of LLVM than 12 ? @Shritesh Bhattarai
Shritesh Bhattarai (Oct 21 2021 at 15:07):Honestly, I don't know. Reading BUILDING_FROM_SOURCE.md, it seems like it is recommended to use LLVM's apt remote to install.
Oliver Schöning (Oct 21 2021 at 15:11):Hmmm... I might be in trouble then:

That just looks like the script doesn't realize pop is ubuntu
Brendan Hansknecht (Oct 21 2021 at 15:22):You might need to slightly modify it to hardcode your distro as ubuntu.

from https://github.com/rtfeldman/roc/blob/trunk/BUILDING_FROM_SOURCE.md
Oliver Schöning (Oct 21 2021 at 15:26):Looking at apt.llvm.org Default Packages section now. I wonder if I can just run:
apt-get install clang-format clang-tidy clang-tools clang clangd libc++-dev libc++1 libc++abi-dev libc++abi1 libclang-dev libclang1 liblldb-dev libllvm-ocaml-dev libomp-dev libomp5 lld lldb llvm-dev llvm-runtime llvm python-clang
This is very new territory for me hehe. I am used to npm i :smiley:
Brendan Hansknecht (Oct 21 2021 at 15:29):First you need to add the llvm ppa, then that would work correctly
Oliver Schöning (Oct 21 2021 at 15:30):So am I understanding it correctly that the sudo bash -c "$(wget -O - https://apt.llvm.org/llvm.sh)" is sugar for that longer sudo apt-get install ?
Folkert de Vries (Oct 21 2021 at 15:31):These days I just download the llvm zip file
Folkert de Vries (Oct 21 2021 at 15:32):On Linux mint
Brendan Hansknecht (Oct 21 2021 at 15:33):Also, the script does a few more things than just an install command. This is the core:
wget -O - https://apt.llvm.org/llvm-snapshot.gpg.key | apt-key add -
add-apt-repository "${REPO_NAME}"
apt-get update
apt-get install -y clang-$LLVM_VERSION lldb-$LLVM_VERSION lld-$LLVM_VERSION clangd-$LLVM_VERSION
Which zip and what version @Folkert de Vries ?
Folkert de Vries (Oct 21 2021 at 15:34):from this page
Folkert de Vries (Oct 21 2021 at 15:34):https://github.com/llvm/llvm-project/releases/tag/llvmorg-12.0.0
Brendan Hansknecht (Oct 21 2021 at 15:35):I think that should be 12.0.1 now
Folkert de Vries (Oct 21 2021 at 15:35):then define your equvalent of this variable set -x LLVM_SYS_120_PREFIX "/home/folkertdev/Downloads/clang+llvm-12.0.0-x86_64-linux-gnu-ubuntu-20.04"
Folkert de Vries (Oct 21 2021 at 15:35):not with zig 0.8.0
Folkert de Vries (Oct 21 2021 at 15:35):or at least, that is untested
Folkert de Vries (Oct 21 2021 at 15:36):and then you may need to symlink some executables or add the /bin folder from the extracted archive to your PATH
Oliver Schöning (Oct 21 2021 at 16:04):@Folkert de Vries hmm but I already have llvm 12 I think
oliverschoning@pop-os:~/Projects/roc$ llvm-config --version
12.0.0
and zig 0.8.1
Folkert de Vries (Oct 21 2021 at 16:17):Sorry what is failing then?

I installed llvm via sudo apt install llvm
Folkert de Vries (Oct 21 2021 at 16:26):can you define the shell variable like I showed, that might llvm-sys figure things out
Oliver Schöning (Oct 21 2021 at 16:31):Sorry @Folkert de Vries but I am unfamilliar with setting a variable like this:
set -x LLVM_SYS_120_PREFIX "/home/folkertdev/Downloads/clang+llvm-12.0.0-x86_64-linux-gnu-ubuntu-20.04"
I can set something in my .bashrc if that is the idea? But I also do not know the path like you specified since I did not download it into my home/username/Downloads folder.
Do you have some more hints so I can figure it out? :smile:
Folkert de Vries (Oct 21 2021 at 16:33):allright first we need to figure out where llvm is actually installed
Folkert de Vries (Oct 21 2021 at 16:35):first try which llvm-as
Oliver Schöning (Oct 21 2021 at 16:35):/usr/bin/llvm-as
Folkert de Vries (Oct 21 2021 at 16:36):and then that should hopefully be a symlink
Folkert de Vries (Oct 21 2021 at 16:36):maybe ls -h /usr/bin/llvm-as works?
Oliver Schöning (Oct 21 2021 at 16:37):oliverschoning@pop-os:~$ ls -h /usr/bin/llvm-as
/usr/bin/llvm-as
actually try readlink -f /usr/bin/llvm-as
Oliver Schöning (Oct 21 2021 at 16:37):Look at us, pair programming without a video share or call :grinning_face_with_smiling_eyes:
Oliver Schöning (Oct 21 2021 at 16:38):oliverschoning@pop-os:~$ readlink -f /usr/bin/llvm-as
/usr/lib/llvm-12/bin/llvm-as
cool, eh then in the .bashrc
Folkert de Vries (Oct 21 2021 at 16:39):export LLVM_SYS_120_PREFIX="<that path>"
Folkert de Vries (Oct 21 2021 at 16:39):actually, just /usr/lib/llvm-12
Folkert de Vries (Oct 21 2021 at 16:40):and then I think source ~/.bashrc before you try running cargo again
Oliver Schöning (Oct 21 2021 at 16:40):Just export /usr/... you mean?
Folkert de Vries (Oct 21 2021 at 16:41):export LLVM_SYS_120_PREFIX="/usr/lib/llvm-12"
Oliver Schöning (Oct 21 2021 at 16:42):Ok I did the source command
Folkert de Vries (Oct 21 2021 at 16:44):right so then you can try compiling again
Folkert de Vries (Oct 21 2021 at 16:45):(in the shell where you did the source)
Oliver Schöning (Oct 21 2021 at 16:50):Oh, adding to .bashrc does not make it permanent to all terminals?

Folkert de Vries (Oct 21 2021 at 16:54):here
I'm attempting to use LLVM bindings in Rust, the common bindings are the
llvm-sys crate. To link, they use
llvm-config-10 --link-static --libnames
to find all the libraries. That list includes libPolly.a which isn't
installed
as part of llvm-10 but is instead included in libclang-common-10-dev which
may or may not be installed.
Folkert de Vries (Oct 21 2021 at 16:54):https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=966574
Folkert de Vries (Oct 21 2021 at 16:54):you also need to install libclang-common-dev-12-dev it seems
Oliver Schöning (Oct 21 2021 at 17:00):To make sure always the most recent versions of the packages are installed, we are providing some default packages.
To install all of them (currently version 14):
apt-get install clang-format clang-tidy clang-tools clang clangd libc++-dev libc++1 libc++abi-dev libc++abi1 libclang-dev libclang1 liblldb-dev libllvm-ocaml-dev libomp-dev libomp5 lld lldb llvm-dev llvm-runtime llvm python-clang

Oliver Schöning (Oct 21 2021 at 17:00):Maybe I need to manually install these then?
Oliver Schöning (Oct 21 2021 at 17:06):I downloaded the llvm.sh file. Perhaps I can tweak it to accept my distro
Oliver Schöning (Oct 21 2021 at 17:11):Its based on ubuntu 21.04. So just a wild guess that I can change the Ubuntu_21.04 to Pop_21.04

oh wait. I see it now
Brendan Hansknecht (Oct 21 2021 at 19:23):make sure to git pull I just made the branch
Oliver Schöning (Oct 21 2021 at 19:33):A unfortunately same issue. The cargo test hangs right now and a lot of failed. And Cargo run gives:

I just pushed one more commit to temporarily disable the arch flag, can you pull and run one more time? I am really confused as to the issue your version of ld is having the the arch flag.
Oliver Schöning (Oct 21 2021 at 19:42):Will do! Most likely I messed up the install I assume

I was hower able to write 1 + 1 in the repl this time!
Brendan Hansknecht (Oct 21 2021 at 19:53):Oh, you need to install valgrind
Brendan Hansknecht (Oct 21 2021 at 19:54):Should just be an sudo apt install valgrind
Oliver Schöning (Oct 21 2021 at 19:57):Omg it worked!
Now only one tests fails and I was able to run helloworld!
test cli_run::astar ... FAILED <- this test
Oliver Schöning (Oct 21 2021 at 19:57):Thank you very much @Brendan Hansknecht
Brendan Hansknecht (Oct 21 2021 at 19:59):If you run the tests again or just that test alone, does it consistently fail. I think our tests have a minor filesystem race condition that hasn't been fixed yet.
Oliver Schöning (Oct 21 2021 at 20:05):How can I run a single test?
Folkert de Vries (Oct 21 2021 at 20:09):cargo test --test cli_run deriv should run just the deriv cli test
Oliver Schöning (Oct 21 2021 at 20:16):I have re-run the all tests a couple of times. Sometimes they hang:
test cli_run::cfold has been running for over 60 seconds
test cli_run::cli has been running for over 60 seconds
Sometimes a test fails, never the same, sometimes they all pass.
Very confusing
Folkert de Vries (Oct 21 2021 at 20:18):yea that happens, seems like you're hit hard by it though
Folkert de Vries (Oct 21 2021 at 20:18):there is some race condition in there
Folkert de Vries (Oct 21 2021 at 20:18):does cargo test --test cli_run -- --test-threads 1 work?
Folkert de Vries (Oct 21 2021 at 20:19):(it is going to be slow, but it should be correct)
Oliver Schöning (Oct 21 2021 at 20:23):Running it now. Why are tests sometimes failing tho? That's not how I usually expect unit tests to work haha
Brendan Hansknecht (Oct 21 2021 at 20:26):Those are integration tests and a number of them generate the same file. So sometimes they delete the file while another test is using it. I thought we set them to run sequentially but I guess it doesn't work.
Oliver Schöning (Oct 21 2021 at 20:27):Result from:

Cool. You have a working compiler. The warning messages are due to my quick hacks to disable the -arch
Brendan Hansknecht (Oct 21 2021 at 20:28):Still need to figure out what exactly is going on there.
Oliver Schöning (Oct 21 2021 at 20:30)::tada: yay! thanks so much
Oliver Schöning (Oct 21 2021 at 20:30):I can live with this, eventually there will be an installer I assume :D
Folkert de Vries (Oct 21 2021 at 20:30):@Brendan Hansknecht those tests don't run sequentially normally
Folkert de Vries (Oct 21 2021 at 20:31):it just seems that some machines are more likely to run into that race condition
Folkert de Vries (Oct 21 2021 at 20:31):maybe based on processor speed or number of cores
Brendan Hansknecht (Oct 21 2021 at 20:32):Oh, i didn't realize. We should maybe at least make the ones in the benchmarks folder run sequentially. Or first compile the host and then use the --precompiled-host flag.
Folkert de Vries (Oct 21 2021 at 20:33):that flag exists?
Folkert de Vries (Oct 21 2021 at 20:33):if so we can use it, on ci at least
Folkert de Vries (Oct 21 2021 at 20:34):because there one of the tests is run to compile the host, effectively pre-compiling it for the rest
Brendan Hansknecht (Oct 21 2021 at 20:34):I added the flag as part of linker changes
Folkert de Vries (Oct 21 2021 at 20:34):oh, excellent
Anton (Oct 22 2021 at 08:27):Thanks for working through this with us @Oliver Schöning ! I have improved the llvm installation instructions for Ubuntu/Debian, I'll also be working on a complete install script today.
Oliver Schöning (Oct 22 2021 at 10:35):@Anton omg no problem! I’m just very grateful for all the help I’ve gotten! Clearly the Elm community spirit also lives in Roc ❤️
Luiz de Oliveira (Oct 30 2021 at 19:10):@Brendan Hansknecht and @Oliver Schöning I think this PR will solve the -arch problem: https://github.com/rtfeldman/roc/pull/1851
Could you guys take a look? @Oliver Schöning this change should make it work smooth.
