wolframresearch / wolfram-app-discovery-rs Goto Github PK

I tried using this on our local cluster (Linux), which provides several different Mathematica versions via modules. I tried it with Mathematica 12.3 (which happened to be the most recent version available).

1. It was initially unable to find the installation:

   $ wolfram-app-discovery default
   warning: error looking for Wolfram apps in '/usr/local/Wolfram': No such file or directory (os error 2)
   warning: error looking for Wolfram apps in '/opt/Wolfram': No such file or directory (os error 2)
   Error: Error(Undiscoverable { resource: "default Wolfram Language installation", environment_variable:    Some("WOLFRAM_APP_DIRECTORY") })
   

   this is despite the binary directory being in the PATH. For example:

   WolframKernel -noprompt -run "WriteString[\$Output,\$InstallationDirectory];Exit[]"
   

   gives me the correct directory.

2. I then set the WOLFRAM_APP_DIRECTORY environment variable. This then gave the following error:

   $ wolfram-app-discovery default
   Error: Error(Other("Unable to determine Wolfram app type from LICENSE.txt: first line was: \"Wolfram Mathematica License Agreement\""))
   

OS: Pop!_OS 22.04
Wolfram products: Mathematica 13.1 and 12.0

Issue:
WolframApp::try_default() returns an Error on Linux and Other operating systems when try_wolframscript_installation_directory() is successful because WolframApp::from_installation_directory(dir) errors for these system types. This is incorrect behavior, since wolframscript is discoverable on $PATH thus wolfram_app_discovery::discover_with_filter should be given a chance to locate it.
I am working on a Pull Request that will add minimal extra logic within try_default() to solve the problem.

Using Wolfram Engine installed by Homebrew (brew install --cask wolfram-engine), I get the following error:

Suggestion: Add functionality to output the result as JSON

Hi,
the program has trouble locating Wolfram Language installation on Linux. Locating Wolfram application using wolfram_app_discovery::WolframApp leads to an error

thread 'main' panicked at 'unable to locate any Wolfram applications: Error(UnsupportedPlatform { operation: "WolframApp::from_installation_directory()" })' 

According to the section Configuration it should be sufficient to add the correct path to .bashrc, such as
export WOLFRAM_APP_DIRECTORY="/usr/local/Wolfram/Mathematica/13.0/Executables/"
this also leads to the error above.

• Installing wolframscript does not fix the problem,
• using Arch Linux, Mathematica 13.0, rustc 1.65.0, wolfram-app-discovery = "0.3.0"

For more details, the result from RUST_BACKTRACE=1:

thread 'main' panicked at 'unable to locate any Wolfram applications: Error(UnsupportedPlatform { operation: "WolframApp::from_app_directory()" })', src/main.rs:8:6

Thanks for any advice on fixing this issue.

I would like to use this as part of https://github.com/JuliaInterop/MathLink.jl/ for finding the WSTP dynamic library. I can find the "WSTP CompilerAdditions directory" which is close, but it seems like the location of the dynamic library from here can be different on different OSes.

When I attempt to run:

wolfram-app-discovery default --raw-value kernel-executable-path

using the wolframresearch/wolframengine:latest container, I get the following error:

Error(UnsupportedPlatform { operation: "WolframApp::from_installation_directory()", target_os: Linux })
