Hi ! Sorry to bother, it's probably a mistake from my part but I don't find any documentation about this issue.

I followed llvm-hs install directions for mac OS (brew install llvm-hs/llvm/llvm-9). It installed a bunch of binaries such as llvm-...-9.

First of all, I don't have any llvm-config as you asked in the README. However, I do have a llvm-config-9. When I run it, it prints 9.0.0. Is that an issue I should be aware of ? (if you feel that I asked on the wrong repository, don't bother with this issue).

Second of all, I ran stack exec basic. After a lot of installation, it printed me this error : 

Executable named basic not found on path: ["/Users/skaas/tek3/llvm-hs-examples/.stack-work/install/x86_64-osx/d9d41a784075cf372862fbb26cc4c250326d7cca4e792a350578331a3c35bb78/8.6.5/bin","/Users/skaas/.stack/snapshots/x86_64-osx/d9d41a784075cf372862fbb26cc4c250326d7cca4e792a350578331a3c35bb78/8.6.5/bin","/Users/skaas/.stack/compiler-tools/x86_64-osx/ghc-8.6.5/bin","/Users/skaas/.sta

I suppose I have to stack build even if it's now written in the README but when I do it, it gives me this error :

I never met this issue before and I don't understand where installation could have failed, I literally just ran brew install.

Do you have any idea of what could be wrong ? Should I post the issue on the llvm-hs repository ?

Thank for your attention.

When I run with cabal : cabal run basic, I got the expected output I think : 

; ModuleID = 'basic'
source_filename = "<string>"

define i32 @add(i32 %a, i32 %b) {
entry:
  %result = add i32 %a, %b
  ret i32 %result
}

This is almost certainly a MacOS issue building the LLVM library itself, I would post on the homebrew-llvm tracker to see if anyone has encountered this before. Our support of Mac is best effort as most of the maintainers are Linux-only.

@sdiehl this is definitely an llvm-hs problem; it won't get to trying to build llvm-hs until LLVM itself is installed.

@skasyn what is your Xcode / clang version?

skasyn commented 4 years ago

Thanks for replying . Everything should be up to date since I had to install Xcode in order to build llvm (brew install llvm-hs/llvm/llvm-9 won't run if Xcode is not fully installed)

Xcode 11.3.1
Build version 11C504
Apple clang version 11.0.0 (clang-1100.0.33.17)
Target: x86_64-apple-darwin19.3.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

I must stress that using cabal install or cabal run links with LLVM just fine. I can use LLVM on my computer and I can build ir, .o and .s files.

delreluca commented 3 years ago

I encountered the same issue and the fix was to bump llvm-hs-9.0.0 to llvm-hs-9.0.1 in the stack.yaml extra dependencies. Sorry for commenting on an old issue but maybe it helps someone else.
