Subject: Re: Aboriginal musl support
Hey, sorry for the late reply... I saw the announcement at the aboriginal
mailing list and confused it with musl's. The link is already posted, but,
for reference here it goes. You can check out the commits for details at
http://landley.net/hg/aboriginal/rss-log and http://landley.net/notes.html

Subject: [Aboriginal] basic musl support is in.
To enable it for a given target, comment out the UCLIBC_CONFIG stanza in
the sources/targets/$ARCH file.
All I can really say at the moment is that it compiles for i686. (That's
the ccwrap rewrite, basic script tweaks, and a patch to gcc to not use a
nonstandard type name.)
Sorry that took so long. It was a lot of debugging. (And now to test
build more stuff...)
Rob

Regards,
Carlos
