2 errors on installing and using `futhark` #107

Open theSherwood opened 3 weeks ago

theSherwood commented 3 weeks ago

Here are a couple errors I'm getting. On my mac, I'm getting an error on installation of futhark. On replit, I'm getting an error trying to use it.

mac

I'm on macOS Monterey 12.6.3

Error message attempting to install futhark:

$ nimble install futhark
Downloading https://github.com/PMunch/futhark using git
   Warning: Package 'futhark' has an incorrect structure. The top level of the package source directory should contain at most one module, named 'futhark.nim', but a file named 'opir.nim' was found. This will be an error in the future.
      Hint: If this is the primary source file in the package, rename it to 'futhark.nim'. If it's a source file required by the main module, or if it is one of several modules exposed by 'futhark', then move it into a 'futhark/' subdirectory. If it's a test file or otherwise not required to build the the package 'futhark.nim', prevent its installation by adding `skipFiles = @["opir.nim"]` to the .nimble file. See https://github.com/nim-lang/nimble#libraries for more info.

The first issue seems to be a problem where building opir (the helper tool for Futhark) on your machine fails because it can't find the C standard library. Are you able to compile other Nim programs?

The second issue seems to be that stdlib.h can't be found, not quite sure why that would happen. Only guess is that you've set up your paths incorrectly somehow. This works for me:

Using nim 2.0.4, Futhark 0.13.1, and clang 17.0.6. But your setup should work as well.

The first issue seems to be a problem where building opir (the helper tool for Futhark) on your machine fails because it can't find the C standard library. Are you able to compile other Nim programs?

Yes. On my mac I can install other nimble packages and compile and run Nim programs without issue.

The second issue seems to be that stdlib.h can't be found, not quite sure why that would happen. Only guess is that you've set up your paths incorrectly somehow.

I've got a very similar directory tree in my replit codebase:

.
├── tree-sitter
│   └── lib
│       └── include
│           └── tree_sitter
│               └── api.h
└── main.nim

And I can compile and run C source files that include stdlib.h and I can compile and run Nim files that don't use Futhark's importc.
