The ARM1176 from the original pi has been replaced by a quad core Cortex A7 processor.Therefore, in order to compile effectively for the Raspberry-Pi 2 we use a different set of compiler options: You can see from the ARM specification of the Cortex A7 that it contains a VFPV4 floating point processor and a NEON engine.On Linux install the relevant package which is usually something like I tried the current 4.9 release and it doesn’t work with some of the examples here, it generates incorrect code, so stick to the 4.7 series until that’s sorted out.This is the compiler I’m using throughout these tutorials.The V1 boards are fitted with the Broadcom BCM2835 (ARM1176) and the V2 board uses the BCM2836 (ARM Cortex A7).

I suggest you install it (on Windows I would install it somewhere without spaces in the file path) so that you have it in your path.The compiler converts C statements into assembler and performs optimisation of the assembly instructions. The C compiler then implicitly calls the assembler to assemble that file (usually a temporary) into an object file.This will have relocatable machine code in it along with symbol information for the linker to use.So where the start of a C program is the main symbol, in assembler we need to refer to it as it’s assembler version which is _main.All of the source in the tutorials is available from the Github repo.The settings are gleaned from the GCC ARM options page.In order to use a C compiler, we need to understand what the compiler does and what the linker does in order to generate executable code.Lets compile and link the following program: There are build “scripts” for each of the different types of Raspberry-pi under the part-1/armc-00 directory of the tutorials source code.There are three types, the original which is targeted with built.bat/sh, the B which has the extended IO connector and fixing holes but it still a V1 RPi which is targeting using build-rpi-bplus.bat/sh and finally the V2 board which features a quad core processor and also has the extended IO connector and fixing holes which is targeted with build-rpi-2.bat/sh.These days the C compiler pipes the assembly to the assembler so there is no intermediate file as creating files is a lot slower than passing data from one program to another through a pipe.The linker’s job is to link everything into an executable file. The linker script tells the linker how to organise the various object files.

  3. In this part of the tutorial we’ll look deeper into the linker and the C-Library so that we end up with a working C-Library link. Exciting stuff, huh. Let’s look.
