ghc install on El Capitan hangs during make

[nodesocket]

Tried installing ghc like 5 times. Every time it hangs on the make of ghc. It just shows make. I waited over 2 hours one of the times.

Running El Capitan 10.11 Beta (15A216g)

Anything in brew gist-logs ghc?

Note that GHC can take hours to install from source. Hours and hours and hours. You can pass --verbose to brew to see what's going on at a finer level of detail.

Do I really need ghc just for an updated version of shellcheck then? Seems crazy to have to wait hours and hours and hours.

[DomT4]

On 10.11, yeah, you will for now 😞. Once we start building bottles for El Capitan life will get easier for 10.11 users, but at the moment the development situation is still too fluid to do so.

shellcheck uses ghc to build. Usually most people never touch or see :build dependencies because on 10.8-10.10 we provide bottles, and when you pour from a bottle you don't have to install the :build dep, obviously.

The new shellcheck wasn't a huge release, If you don't want to wait hours for ghc to do its thing your best bet is probably to brew pin shellcheck for now to stop it updating.

@DomT4 awesome, thanks for the explanation.

Is there a Gratipay for Homebrew? We'd (Commando.io) like to donate.

[DomT4]

We started landing bottles at the start of last October for Yosemite if that's useful, but there's no set timetable really, whenever stability and demand meet a common ground 😉.

I'm not actually sure at the moment. Gratipay made some fairly major changes and have been requiring teams to jump through some loopholes to get active again. If it's working, the link is https://gratipay.com/~Homebrew/. I've asked @MikeMcQuaid to take a look at the situation. Thanks for the kind offer! We ❤️ the community's support for Homebrew.

Closing here per as best a resolution as we can manage for 10.11 right now, but feel free to ping us if you have any more questions about the situation. There's a broad tracking issue in #40837.

It was likely just compiling. I installed ghc 7.10.1_1 yesterday on 10.11 Beta 3 (15A216g) and it worked fine. Compile time was ~2-3 hours on a late 2013 13" rMBP.

@felixbuenemann could you please share the built binary?

[felixbuenemann]

@supermarin I created a formula to install the official ghc binaries using homebrew. That's way better than downloading binaries compiled by random people on the internet 😃

[supermarin]

Thanks! it still took 1/2 hour of frying, but works 👍

[felixbuenemann]

It takes roughly a minute for me, including the download.
