From 20f86a0aeaad5dfa0b4f50bf5d04dd7bf1f7c3e9 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 27 Feb 2014 13:26:21 -0700 Subject: [PATCH] sandbox: Deal with conflicting getenv() for SDL Unfortunately SDL requires getenv() to operate, since it wants to figure out the display type. U-Boot has its own getenv() and they conflict. As a work-around use #define to resolve the conflict. A better but more complex solution might be to rename some U-Boot symbols at link time. SDL audio is not functional at present, likely due to a related issue. Note: Vic Yank wrote a script for this, filed in crbug.com/271125.
