No valid pineappl installation found when running pinefarm

[comane]

I am running pinefarm (installed with pip) as following:

pinefarm run runcards/ATLAS_TTB_13TEV_TOT theory_200_1.yaml

The command is executed in a fresh conda environment in which I have only installed lhapdf (but no pineappl.).

The run crashes in the following way, so it seems that pinefarm is not installing PineAPPL on the fly as said in (https://pinefarm.readthedocs.io/en/latest/run.html)

Moreover, the .prefix/bin folder generated in the same folder in which I run pinefarm is empty

Note: that in issue #47 I was running pinefarm in an environment with pineappl already installed. This however was giving an error shown below and reported at (https://bugs.launchpad.net/mg5amcnlo/+bug/2043460)

oookay, so this sounds back like a pinefarm problem (and not an mg5 one) ...

• when you hit run for the first time all necessary tools should indeed install themselves (and if they are already present, the script will tell you)
• in your case that should be pineappl (including the CAPI) and mg5 - did you hit those installers? (from here to there )
• I think those installers print to stdout - can you check whether you have cargo cinstall ... there somewhere (this one)? that should install the CAPI
• is the CAPI actually present in your current env? i.e. does the file pineappl_capi.h exist somewhere? like-wise does the command pineappl-config exist somewhere? (I'm not sure at the moment how mg5 is receiving that path ...)

[comane]

is the CAPI actually present in your current env? i.e. does the file pineappl_capi.h

No this file doesn't exist anywhere in my env. I am not even sure it is supposed to be there since I am not installing in dev mode.

does the command pineappl-config exist somewhere? (I'm not sure at the moment how mg5 is receiving that path ...)

I can't find it in my conda environment bin. This might be the problem since mg5 crashes like so:

Error detected in "launch auto " write debug file /store/DAMTP/mnc33/Projects_store/PhD/nnpdf40_pheno/pinefarm_runs/results/200-ATLAS_TTB_13TEV_TOT--20231116151158/ATLAS_TTB_13TEV_TOT/run_01_tag_1_debug.log If you need help with this issue, please, contact us on https://answers.launchpad.net/mg5amcnlo str : No valid pineappl installation found.

you mean dev mode for pinefarm? that does not matter - since mg5 will need it in any case (since it is compiling on its own) and indeed it should be installed in any case; the commands I posted above ARE pinefarm, so pinefarm can and (hopefully) will install programs on its own; and here for mg5 pinefarm should realize that he needs the CAPI and so provide the CAPI

[comane]

Regarding this:

• I think those installers print to stdout - can you check whether you have cargo cinstall ... there somewhere (this one)? that should install the CAPI

I do not have cinstall:

cargo cinstall
error: no such command: `cinstall`

	Did you mean `install`?

	View all installed commands with `cargo --list`

[felixhekhorn]

This sounds like you really not went through the install.pineappl routine ...

Can you please make a new env and print the full output of pinefarm run runcards/ATLAS_TTB_13TEV_TOT theory_200_1.yaml ? specifically, I'm interested in the install outputs this call should trigger ...

[comane]

@felixhekhorn , I had to cancel most of the fortran error output, as the comment would have not fitted in the page

[felixhekhorn]

also a text file would have been fine 🤣 (you can still edit your post 😇 )

now the relevant lines are these ones:

Could not find directory of OpenSSL installation, and this -sys crate cannot
proceed without this knowledge. If OpenSSL is installed and this crate had
trouble finding it, you can set the OPENSSL_DIR environment variable for the
compilation process.

Make sure you also have the development packages of openssl installed.
For example, libssl-dev on Ubuntu or openssl-devel on Fedora.

and so cargo fails, i.e. pineappl fails and so you run into the problem - can you please try to apply the suggested fix?

Here is the .txt file

@felixhekhorn thank you so much for the assistance.

So after installing openssl it works!

I had to do the following:

wget https://www.openssl.org/source/openssl-1.1.1k.tar.gz
tar -zxvf openssl-1.1.1k.tar.gz
cd openssl-1.1.1k

./config --prefix=$HOME/usr --openssldir=$HOME/usr/openssl
make
make install

Add folder containing openssl.pc (libssl.pc) to PKG_CONFIG_PATH

the run generates the pineappl grid, however I still get an error at the end of the run:

good we were able to solve something! 👍

how did you solve the brz issue? (that should have been installed together with mg5 ...)

remember to close the mg5 bug (and say it actually was not a bug)
