Serenity: configure: cannot find sources in or ..

[danboid]

I'm still on my quest to get a configure script to run under serenity using bash. I have tried a few different configure scripts for different programs. I change the hashbang to /usr/local/bin/bash first but they all only get as far as:

error: cannot find sources in  or ..

You'd expect that error to read:

error: cannot find sources in . or ..

@alimpfard I see our expr doesn't support match yet and looks like configure autoHELL needs it.

[danboid]

Someone dropped autohell in irc recently and it's become an earworm of sorts, a fave phrase even.

[alimpfard]

I see our expr doesn't support match yet and looks like configure autoHELL needs it.

I did mention that a while back, until we get a regex library, expr won't have a working match

autohell

I'm glad it stuck

I also noticed these errors printed to the qemu terminal when I run configure:

Those are very likely just sys$exit() dumping a backtrace, it does that when the exit code isn't 0.

[danboid]

OK.

As for regex. doesn't LibJS already have some regex support? Shouldn't that that be pulled out of LibJS so other apps can use it without pulling in LibJS?

[linusg]

doesn't LibJS already have some regex support?

No. It parses regex literals to not choke on scripts containing them, but doesn't have any regex functionality beyond that.

[danboid]

I'm sure a saw a PR for a regex engine a while back. Did I imagine it or did that get scrapped?

EDIT

I wasn't imagining it, it was this:

https://github.com/SerenityOS/serenity/pull/2363

[nooga]

It's a shame #2363 got abandoned, it seemed more or less complete and functional.

[danboid]

Yeah, it looks like they had written a new grep to go with it too.

[alimpfard]

@danboid does the (now available) match support in expr help this issue?

[danboid]

Still cannae run configure:

[danboid]

Already done that L!

[alimpfard]

Why is that using our shell to run configure...?
