From 215edb9840e5a75ed961fbf8b6ce423116deef28 Mon Sep 17 00:00:00 2001 From: aguestuser Date: Sun, 23 Apr 2017 20:36:37 -0400 Subject: [ag] eliminate hacky workaround for 64-bit builds * HACK: replace all toolchain references to `linux-x86_64` with `linux-x86` * FIX: provide dependency on `file` package that will allow `ndk-build` to detect 32-bit userland, making this * side-effects: * group sdk/env vars with installation code that uses them * add explanatory note about why we use outdated version of `android-ndk` ------------------ *Explanation:* More careful analysis of the meaning of the word `file` in this (subtle!) error message: ```shell /opt/android-sdk-linux/android-ndk-r12b/build/ndk-build: 143: /opt/android-sdk-linux/android-ndk-r12b/build/ndk-build: file: not found ``` led to inspecting line 143 of `ndk-build`, revealing an undefined variable called `file` that would allow `ndk-build` to detect a 32-bit userland: ```shell file -L "$SHELL" | grep -q "x86[_-]64" ``` Thus the error messsage was *not* trying to tell us that a file could not be found, but that the program called `file` could not be found.
