This concerns the "glibc" package.
Up until today, my "makepkg" experience was--
1] Download a relatively small archive.
2] Decompress the archive's files in a subdirectory somewhere.
3] Run "makepkg".
4] Applaud the result.
I need a copy of "libc.so" built without the "enable-lock-elision" switch, for a Raspberry Pi 2 installation of ALA. So I performed steps 1-3, expecting step 4 would follow shortly. Instead, "makepkg" immediately whined about a missing PKGBUILD. When I inspected the contents of the parent directory and its subdirectories, it was obviously lthe result of running "makepkg", not the files required to run it successfully.
So I banged on the "Source Files" link on https://archlinuxarm.org/packages/armv7h/glibc. The four files I found included PKGBUILD. So I converted the relevant piece of four web pages, each containing the file's text, into a correctly named file, and added them to an empty directory.
This time, when I ran "makepkg", I was presented with--
$this->bbcode_second_pass_code('', '==>ERROR: glibc is not available for the "armv7h' architecture.')
At that point, I threw up my hands and wrote this note. Can someone furnish a clue about what's going on here? What have I overlooked?
