- Subject: [patch] help for cross compiling lua
- From: John Hein <jhein@...>
- Date: Tue, 4 Mar 2008 21:05:41 -0700
A classic way to cross compile tools is override
things like CC and RANLIB and AR. When trying to build
lua for an arm-based platform, I employed this technique.
Unfortunately the src/Makefile has 'AR= ar rcu'. So when one
overrides AR (with the cross platform version, arm-ar), building
liblua.a fails because the 'rcu' is missing.
I'd like to submit the following patch to fix that issue.
If there is a better place to submit this, please let me know.
