I am new to ARM
I would like to cross-compile a simple Hello world c++ code for Linux distribution in order to debug and run it on my Hardkernel ODROID-XU4 board. For this purpose I'm following this tutorial https://developer.arm.com/tools-and-software/embedded/legacy-tools/ds-5-development-studio/resources/tutorials/linux-application-debugging-using-ds-5, however, instead of using the built-in compiler, I have downloaded the latest linaro gcc toolchain from this page https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-a/downloads, I have windows 7 sp1. when I followed the steps mentioned in the tutorial, when I buit the project I encountered the following errors

How can solve this problem and build the program correctly and are the flages I'm using during compilation correct ?
Hi,
The arm-eabi-g++ is a bare metal compiler (no operating system) and you are looking for a compiler to build a Linux application.
The one you want to use for 32-bit Linux applications is the on the same page: AArch32 target with hard float (arm-linux-gnueabihf)
The DS-5 tutorial you reference does have this in the Toolchains pain if you look very close.
Let us know if you have any other questions.
Thanks,
Jason
Thanks for the answer, Actually I have figured that what you mentioned and switched to gcc arm-linux-gnueabihf 7.4.1. when I tried to build a simple c++ hello application to debug it on an ARM Linux target. I got the following error

What can I do, to resolve this error ?
