Compile for 32bit ARM target on 64bit Ubuntu [message #1754989]

Hi All,
This is the first time here Smile

I am running Neon2 on Ubuntu 64bit 16.04LTS. I have installed arm-linux-gnueabi and I can build a sample HelloWorld using cross-compile without any issue.
But I need to build for a 32 bit target board. I tried using -m32 option but it throws an error.

Anyone has similar setup? what settings do I need on my Neon?

Thanks
Silas

Hi Silas,

Can I recommend heading over to http://gnuarmeclipse.github.io/ it has lots of documentation on how to build for ARM using Eclipse. They even have extensions to CDT allowing easier use of ARM toolchains.

Sadly I don't have an answer to your specific question, so hopefully gnuarmeclipse can help.

Building for ARM doesn't use the -m32 option. GCC accepts either -mcpu=[target] or -march=[arch].
