I am new to haskell. I have the simplest of simple programs.
#!/usr/bin/env stack
-- stack --resolver lts-13.7 script
module Main where
import Lib
main :: IO ()
main = putStrLn "Hello World"
It does work for stack
$stack ./Main.hs
Hello World
(base) 19:48:11/app $
But it suffers a rather gruesome demise on anything more extravagent:
$stack build --test --haddock --no-haddock-hyperlink-source;
Stack has not been tested with GHC versions above 8.6, and using 8.8.3, this may fail

I tried searching for these but did not run into obvious matches/solutions. Tips?
Update haskell and stack were installed as such:
brew install haskell-stack
Another update I am trying to navigate to install from the haskell platform.
The asker is not off in left field but instead following the directions provided by the Haskell platform https://www.haskell.org/platform/
There is no download link there so we resort to googling for download ghcup which leads us to https://www.haskell.org/ghcup/
Then running the command
curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | sh
The result is:
$curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | sh
This did install ghcup correctly
$ghcup
ghcup 0.0.8
GHC up toolchain installer
USAGE:
ghcup [FLAGS] <SUBCOMMAND>
Next in line: cabal. Google search led me to: https://hackage.haskell.org/package/cabal-install
I downloaded the cabal-install tarball https://hackage.haskell.org/package/cabal-install-3.2.0.0/cabal-install-3.2.0.0.tar.gz
This one was not so cooperative. The short version of the errors is:

And Another update
Per a comment from #bradm I have tried the Haskell Stack http://docs.haskellstack.org/en/stable/README/#how-to-install . The same errors occur as at beginning of my question. I did double check that the stack were newly installed and it shows right now timestamp. It fails on stack setup within a new dummy project and has the same signature of long ugly errors including linker error on Main.o bad relocation . Here is the core of it (same as at top):
Cannot open /Users/steve/.stack/setup-exe-src/setup-mPHDZzAJ.o: bad relocation (Invalid pointer diff) in section __TEXT/__text (r1_address=21c, r1_type=5, r1_extern=1, r1_length=2, r1_pcrel=0, r1_symbolnum=37), (r2_address=21c, r2_type=0, r2_extern=1, r2_length=2, r2_pcrel=0, r2_symbolnum=30)

I just found this known bug: https://github.com/commercialhaskell/stack/issues/4373
That is exactly what I'm seeing.
The workaround required is to update a settings file that is buried deep under a newly generated ~/.stack directory https://github.com/commercialhaskell/stack/issues/4373#issuecomment-432726112
Those instructions are incomplete so I added a comment to that bug to clarify. That settings location: ~/.stack/programs/x86_64-osx/ghc-8.8.3/lib/ghc-8.8.3/settings
And this works (note that stack test is a combination of stack build and stack test):

I downloaded and installed stack using the installer on Windows.
I then try to run:
$ stack new new-project rio
$ cd new-project
$ stack run
This leads to this error:

How can I resolve it? I am not even sure how to better understand the actual problem.
I am working with git bash.
I resolved the WARNING by editing stack.yaml. I have also tried installing pkg-config using pacman on mingw as in this answer but the package was not found.
In Mac OS 10.15.7, with haskell platform installed, I am having a weird behavior. The code works fine in ghci but the linking during compilation is not working:

Any idea? I have installed the haskell platform following the instructions in https://www.haskell.org/downloads/ with https://www.haskell.org/platform/mac.html (ghcup).
Code is https://gist.github.com/arademaker/e7ae2e1ef5225807a3e627caa61481da
I had a directory with the same name in the folder! My mistake.
I'm trying do some web scraping using HXT, but one dependency, hxt-regex-xmlschema-9.2.0, always fails to install. The error is ld: library not found for -lHSparsec-3.1.7-ghc7.8.3. I don't understand why the linking is failing. I have parsec installed - cabal install parsec-3.1.7 worked fine. I'm running OSX 10.10.1, GHC 7.8.3, and gcc 4.9.1.

Failed to install hxt-regex-xmlschema-9.2.0
World file is already up to date.
cabal: Error: some packages failed to install:
hxt-regex-xmlschema-9.2.0 failed during the building phase. The exception was:
ExitFailure 1
Well, I kind of left it for a while, and came back to it now. It worked for some reason. The only thing I can think of is that I upgraded from GHC 7.8.3 to 7.8.4. If anyone comes up with this again, try a different version of GHC.
I'm having trouble building my Haskell library with GHC 7.8.2 and Cabal 1.20.0.2 on OSX 10.9.3 with both -staticlib and -threaded enabled.
The library I'm building exports several functions using FFI to be called from ObjectiveC in an Xcode project. This works fine with just -staticlib enabled, but now I realize I need to call into my Haskell library from multiple OS-threads simultaneously. But when I add -threaded to ghc-options I get an error when linking:
error: libtool: can't locate file for: -lpthread
error: libtool: file: -lpthread is not an object file (not allowed in a library)
Complete ouput:

The linker command that fails looks like this (... replaces a bunch of -l and -L options):
libtool -static -o liba.a dist/build/HsCocoa.o ... -lCffi -lpthread
Does anyone know what could be wrong?

Edit:
After discussing this on Haskell Cafe it was suggested that this could be a bug in GHC. I created a ticket here: https://ghc.haskell.org/trac/ghc/ticket/9189
have a bug with libClang, then i install it with cabal at the end i get:

someone a idea what to do?
I can reproduce this on Arch Linux / x86_64: my libclang build emits a warning about the missing symbol,
src/Clang/FFI_stub_ffi.c:2181:1:
warning: implicit declaration of function ‘clang_toggleCrashRecovery’

and linking a test program:

fails with:

In function `prim_toggleCrashRecovery':
FFI_stub_ffi.c:(.text+0x3513): undefined reference to `clang_toggleCrashRecovery'
collect2: ld returned 1 exit status
The process of solving these kind of linker errors is to identify which C library archive that symbol lives in. Searching in my libclang install, I can't find this symbol:
$ find . -type f -exec grep toggleCrashRecovery {} \;
$ grep toggleCrashRecovery /usr/lib/llvm/*
$ grep toggleCrashRecovery /usr/lib/llvm/*/*
zsh: no matches found: /usr/lib/llvm/*/*
which is a clue that it might be something only available in a different version of libclang. I'm using clang/llvm 2.9, which does not have this symbol, while google does turn up some older headers that do include it. So my best guess is that this symbol is no longer available in LLVM, and thus the current haskell/libclang package depends on LLVM/Clang 2.8.
Solution:
Download the libclang source,
$ cabal unpack libclang
and patch it to remove references to the toggle* functions.
$ ghc --make A.hs

A patched version is here: http://www.galois.com/~dons/tmp/LibClang-0.0.10.tar.gz
I've also forwarded this info to the author.
Thanks Don for the quick fix.
This issue is fixed with the latest version on Hackage:
http://hackage.haskell.org/package/LibClang-0.1.0
Please "cabal update" and you should be good to go.
Alternatively, you could get the source from https://github.com/chetant/LibClang
