   While executing the build plan, Stack encountered the following errors:

   While building package text-icu-0.8.0.2 (scroll up to its section to see the error) using:

I reverted regex support and removed text-icu in #97, so this should be fixed. Please feel free to re-open this if you can still reproduce the issue on the latest main.

I need regex support. it is ok when we build on x86_x64 . it is build fail on mac and aarch64

[SamirTalwar]

OK, that's good to know! Unfortunately most regular expression packages for Haskell require dynamic dependencies that break on certain OS/arch combinations.

Do you think you'd be happy with POSIX support? I am thinking of reintroducing it with regex-tdfa. If you could take a look at that library and let me know if it fits your purposes, it'll help me decide.

if i checkout this commit 2ee7356. ghc version is 9.0.2, text-iuc version is 0.7.1.0
It is ok on aarch64, So if I want enable regex on the latest main, what's lib that i need install .
@SamirTalwar

https://github.com/haskell-hvr/regex-tdfa/issues/3   I think this bug is a big problem .
My smoke test is runing on  arm64 board. little memory .I'm worried that the performance will degrade and the program won't be able to continue

[SamirTalwar]

Oh, thanks for finding that issue. That's not an option, then.

There is no regex support on main any more; I have removed it for now, because I can't get it to reliably build across operating systems. You can check out a previous version but you'll get the same problem as before.

I suggest we carry on this discussion in #69. I'll re-open it.

it is ok on ubuntu 20.04 aarch64 that install pkg-config。
I re-add regex support.
