| 2021-08-17 02:09:54 | <fernand> | Hi everyone. I'm not able to download Haskell 8.2.2 for MacOS. The Link is returning 404 not found https://www.haskell.org/platform/download/8.2.2/Haskell%20Platform%208.2.2%20Full%2064bit-signed.pkg Is there a mirror somewhere else? |
| 2021-08-17 02:11:25 | <Axman6> | why do you want such an ancient GHC version? |
| 2021-08-17 02:12:17 | <fernand> | Axman6 for studying purposes |
| 2021-08-17 02:12:19 | <Axman6> | the haskell platform is no longer the recommended way to get set up, as https://www.haskell.org/platform/ suggests |

| 2021-08-17 02:14:53 | <fernand> | I see. Thanks |

| 2021-08-17 02:15:18 | <Axman6> | fernand: do you specifically need an old GHC? There is a very good chance it will not run on newer macOS versions, Apple have a habbit of breaking things in the build tools that cause old compiters to stop working |

| 2021-08-17 02:17:33 | <Axman6> | just for reference, GHC 8.2.2 was released 2017-11-21 |
| 2021-08-17 02:19:06 | <sm> | a quick test with stack (`stack setup ghc-8.2.2; stack --resolver ghc-8.2.2 exec -- ghc --version`) looks alright |
| 2021-08-17 02:19:58 | <Axman6> | on the latest macOS? Ususally the problems arise when trying to actually compile things |
| 2021-08-17 02:21:20 | <monochrom> | To be more sure, you need to try to compile a file that uses CPP. |
| 2021-08-17 02:21:22 | <fernand> | I am following an old book and they use this version for their code examples. Just wanted to avoid debugging time while learning. |
| 2021-08-17 02:21:46 | <Axman6> | Which book? Any introductory book should hopefully be ok with newer GHCs |
| 2021-08-17 02:21:50 | <sm> | on latest mac software and hardware, `stack --resolver lts-11.22 build` in `shelltestrunner` works (about 30 deps) |
| 2021-08-17 02:21:55 | <monochrom> | That's reasoning. But it cuts both ways. |
| 2021-08-17 02:21:57 | <sm> | this may be more than enough for fernand |
| 2021-08-17 02:21:58 | <monochrom> | err |
| 2021-08-17 02:22:03 | <monochrom> | That's reasonable. But it cuts both ways. |

| 2021-08-17 02:23:05 | <monochrom> | debugging old compiler that doesn't work on new system vs debugging old textbook that doesn't work on new compiler >:) |
| 2021-08-17 02:23:40 | <fernand> | Thanks for all the suggestions. I guess I'll try the newer ghc and see how it goes. |
| 2021-08-17 02:23:47 | <monochrom> | I would say flip a coin. Later, if something goes wrong, blame the coin. |
| 2021-08-17 02:23:58 | <sm> | and `stack --resolver lts-11.22 exec -- bash` gets you a nice ghc 8.2.2 in $PATH |
| 2021-08-17 02:24:35 | <Axman6> | fernand: if you install ghcup, you'll be able to install and switch between a few different GHCs very easily using `ghcup tui` |

| 2021-08-17 02:26:33 | <monochrom> | To a large extent, we in this channel has enough collective memory about code migration to new compilers and standard libraries, so that if you encounter code that doesn't compile and you suspect it's an incompatibility, just give us a URL to a paste, we can quickly identify the fix. |
