eglibc support is ending soon

[thagabe]

This is the last eglibc release, should we look into incorporating glibc to trunk openwrt and as an extension this project? Also would you like to merge the projects then I'll transfer the repo to you, I don't have the time and experience to run this awesome project :p however I will try my best to contribute!

Holy shit, packaging glibc? I touch one weird combination of interesting projects and it blows up in my face like this?! ;-)

[jdub]

So, what are we looking at?

eglibc-2.19-r25243.tar.bz2 = 19M
glibc-2.21.tar.bz2 = 18M (though glibc-2.21.tar.xz is 12M)

There's about 1112 lines of build config for eglibc, not including the 10 patches for two supported versions.

A list of what wasn't merged back to glibc as of February 2014.

What matches eglibc in OpenWrt? Might not all be relevant, but it gives an impression.

Had a quick look to see if anyone was working on it, but didn't come up with anything obvious. So, I'm going to copy eglibc, take out the noise, and have a play. :-)

So, I have make menuconfig working (no build options yet), and am doing a make toolchain/prepare right now. Let's see how it goes. 😃

[jdub]

- [x] copypasta eglibc to glibc - [x] get rid of legacy eglibc mess - [x] make basic s#eglibc#glibc#i changes - [x] integrate into OpenWrt menu + config - [x] `make menuconfig` - [x] `make menuconfig` with glibc selected - [x] `make toolchain/prepare` - [x] `make toolchain/install` 💤

Not a massive size difference, and that's without any interesting configuration options involved.

That didn't seem so hard. I'm going to rebase and tidy up my commits for submission to OpenWrt. :-) Will close this for now. That's for suggesting it!
