IHaskell not building on macOS about ihaskell HOT 2 CLOSED

So, a few hours later, with the help of some web searches, I managed to fix this.

1. Use --extra-... flags (shown in the README; my bad for not doing that in the first place):

   stack install --fast --extra-include-dirs ${HOMEBREW_PREFIX}/include --extra-lib-dirs ${HOMEBREW_PREFIX}/lib

2. In stack.yaml, I bumped the version of Chart-cairo-1.9.3 to 1.9.4.

   This was needed, because stack.yaml is configured (out-of-the-box) with resolver: lts-21.21
   (with GHC 9.4.7), which includes lens-5.2.3,
   which exceeds the requirements for Chart-cairo-1.9.3, but lens-5.2.3 will work with 1.9.4.

   I suggest to fix this on the IHaskell side. (How did it work for others?)

3. Update my XCode command-line tools, which is a bit more complicated nowadays.

   See: https://developer.apple.com/forums/thread/677124

4. Install libmagic (./ihaskell-display/ihaskell-magic seems to need this):

   brew install libmagic

And now building (see the command under Step 1 above) worked (took a while, though, with 157 things to build).

I did get a warning after the build that ihaskell is linked to ~/.local/bin/ihaskell,
which is good to know, since after the build, you then need to run

~/.local/bin/ihaskell install --stack

Finally, after starting a Jupyter server with

stack exec jupyter -- notebook

I could open a notebook with an IHaskell language kernel, and everything worked again!

1. As you noted, this is mentioned in our README.

2. That's strange that it works in CI for us but not for you. I've updated the version of Chart-cairo we pull in with #1436.

3. This is macOS-specific, nothing we can do about it here.

4. Same as 3.

That's a Stack feature.

It sounds like you got everything working in the end, so I will go ahead and close this. Please reopen if necessary.
