[Buildroot] Compiling applications for ARM9

[Abhishek Ashtekar]

Hello,



I have Buildroot running on the AT91SAM9G20 board and want to compile and run own application programs.

With Eclipse, GNU_ARM_Eclipse_Plugin (ARM Linux GCC ) when I try to compile a ' Hello World ', I get the error

/bin/sh: arm-elf-gcc: not found



Then I compiled gnu-arm-installer from mcuprogramming.com that generated arm-elf-gcc in /gnu-arm-installer/install/bin.

After giving this path to C compiler and assembler, Still arm-elf-gcc is not found.



Or do I have to compile my applications using arm-uclibc-gcc ? From where or how do I get it ?



Thanks a lot,



Abhi

arm-elf-gcc is a bare-metal toolchain, so you will not be able to
generate programs that will run under Linux with it.

You should use the toolchain that has been generated by Buildroot, i.e
output/staging/usr/bin/arm-linux-gcc.

Again, arm-elf-gcc is a bare-metal toolchain, which has nothing to do
with a Linux toolchain. You can't pick any toolchain found by randomly
searching "arm toolchain" on Google. You need to understand a little
bit what you are doing.

In output/staging/usr/bin/ in your Buildroot tree.
