Creating Cross-Compile Friendly Software

Typical OSS packages make assumptions about their build environment that are not necessarily true when attempting to cross-compile the software. There are two significant contributors to cross-compile problems: platform-specific code, and host/target/build confusion. Several examples of problems existing in current OSS packages are presented for each of these root causes, along with explanations of how they can be identified, how they could have been avoided, and how they can be resolved.
