Can't find a toolchain for the following configuration #1160

Open Joebeazelman opened 1 year ago

Joebeazelman commented 1 year ago

I get a strange error message when I try to compile my file. If I build using the build command in Visual Studio, I get the following error:

can't find a toolchain for the following configuration

I also get an error message in the problems tab area:

imported project file "pico_bsp.gpr" not found

However, it compiles successfully when I build from VS Code's terminal using alr build. If I go back and execute the build command again, I get:

gprconfig: can't find a toolchain for the following configuration:
gprconfig: language 'ada', target 'arm-eabi', runtime 'light-cortex-m0'
cpu_controller_config.gpr:2:06: imported project file "pico_bsp.gpr" not found

Hello @Joebeazelman ! How can I reproduce this? What is the build command?

I tried to reproduce and it works for me. My steps:

Joebeazelman commented 1 year ago

Not sure what happened, but I tried to set the GNAT version inside the project toml file and the issue started.

Joebeazelman commented 1 year ago

The issue started up again. I can build the project without issue if I execute alr build outside of VSC or directly from its terminal. It consistently complains it cannot find the imported file and that it can't locate the runtime. It only works when I launch VSCode using alr edit from the command-line.

Is there a way of outputting what the LSP extension sees as Alire's environment variables? Usually when you get this error it means it's not seeing Alire's environment's toolchain variables. I suspect it may be confused by my Path.

reznikmm commented 1 year ago

@Joebeazelman I suggest you to create $HOME/.als/traces.cfg file with content

ALS.MAIN=yes

Then ALS starts to write log files in that directory. You should see environment variables in the corresponding log file.

Joebeazelman commented 1 year ago

I examined the dump file and the gprpath is blank. I also didn't see any Alire configured paths. So how is LSP retrieving the paths? Apparently, it's obtaining enough configuration to perform a compile. For what it's worth, this is occurring on a fresh MacOS install. I will investigate some more.

Joebeazelman commented 1 year ago

Below please see the included dump file. As you can see, GPR PATH is blank also there's an exception with a message it can't find the toolchain for the project. Interestingly, LSP is using a toolchain to perform the compilation, although it's unclear which one it's using. This may be related to another issue I opened where it ALS reports more errors than the compiler does.

With the recent new issue opened, I suspect the issue is either unique to MacOS or you may already have a toolchain configured outside of ALR, but it's only a guess.

There's a On_SetTrace_Notification: OFF, would it be helpful to you if I turn this setting on? If so, how do I do it?

Do you have alr in the PATH? I don't see any alire invocation in your trace :thinking:

Which is alr on your system? According to the trace PATH is

PATH: /usr/local/bin:/usr/local/sbin:/usr/local/bin:/System/Cryptexes/App/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin:/var/run/com.apple.security.cryptexd/codex.system/bootstrap/usr/local/bin:/var/run/com.apple.security.cryptexd/codex.system/bootstrap/usr/bin:/var/run/com.apple.security.cryptexd/codex.system/bootstrap/usr/appleinternal/bin

I have the same problem or a similar one. When opening the repository with "code .", I get this error: "can't find a toolchain for the following configuration: language 'Ada', target 'x86_64-linux', default runtime", and navigation to predefined library is not working. The build task works fine invoking alr build.

Also affected without Alire. The same error message following the tutorial just before point Explore Intellisense, and then Intellisense for Ada.Text_IO does not work.

Nevertheless, pressing the Run button in the main, the program is built and run without problem.

gprbuild on PATH is from Ubuntu package gprbuild 2021.0.0.0778b109-5. GNAT is from gnat-12 12.3.0-1ubuntu1~22.04 package.

As I said in my previous comment, the problem is reproducible without Alire. See this screenshot, just after creating the hello_world.gpr following the tutorial; it already marks the problem.

Nevertheless, I tried selecting the toolchain as indicated, but it didn't change the problem in Alire crates opened in vscode. In fact, Alire by itself didn't have any problem when called from the command line and even when called by the vscode extension to build the crate, so my impression this problem is not really related to Alire, but just a problem between the vscode extension and the gprbuild found in the path, which is /usr/bin/gprbuild regardless of the toolchain selection in Alire.

reznikmm commented 2 months ago

ALS can't find Ubuntu/Debian GNAT if its version doesn't match GCC. (in your case gcc 11.2 and gnat 12.3). That is because Ubuntu/Debian maintainers rename gcc to gnatgcc and fix *.xml in gprconfig database. But ASL uses (unfixed) database embedded in libgpr2. This was reported in #1146 and it has not been fixed yet in libgpr/libgpr2/knowledge_db.

mgrojo commented 2 months ago

Thanks, @reznikmm. After aligning versions of Ubuntu's packages for gcc and gnat for version 11 the problem is gone for both cases, working with Alire and plain gprbuild. I've checked also that the Alire version is still navigating to the toolchain selected in Alire. I think I can live with this workaround.
