In this article we look at the C build process – that is, how we get from C source files to executable code, programmed on the target. It wasn’t so long ago this was common knowledge (the halcyon days of the hand-crafted make file!) but modern IDEs are making this knowledge ever-more arcane.
Compilation
The first stage of the build process is compilation.
The compiler is responsible for allocating memory for definitions (static and automatic) and generating opcodes from program statements. A relocatable […]

Please Note: This post is focusing on pre-C99. The reason being is that it is aimed at the embedded C programmer who tends to be working with pre-C99 based cross-compilers. Also I have split it into two as it became my larger, due to feedback, than first anticipated.
On the surface declarations and definitions in C are pretty straight-forward; but once we start introducing the concepts of scope, storage-duration, linkage and namespace life is not so simple.
Program Objects (Variables)
