How to compile my HelloWorld with eclipse to be executed on T2080RDB?

[julencruchaga]

Hello, I need to run a HelloWorld aplication on my T2080RDB board but I can't.

I'm using yocto (bitbake) to generate a fsl-image-minimal where I can find a folder like this:
/build_t2080rdb/tmp/work/t2080rdb-fsl-linux/fsl-image-minimal/1.0-r0/rootfs/usr/bin

where I can find all compilation executables with prefix powerpc-fsl-linux- (g++/gcc).

Then, I'm using eclipse neon to compile the application, and into compilation settings I've included such directory in order to use such executables to compile my application.

As result when eclipse invokes to the linker process, some error are displayed into the console, saying that is not possible to find crt1.o/crti.o/crtbeginT.o

But if I search such libraries into build directory : /build_t2080rdb/tmp/work/t2080rdb-fsl-linux/fsl-image-minimal/1.0-r0/rootfs/usr/lib all of them are installed.

Somebody knows how can I execute a HelloWorld into my T2080RDB board? Is there a Quick Manual to do that? My compilation process is correct or not?

Thank you.

Hello World under u-boot.

Look at attached file. It is u-boot redme file from www.denx.de. See description for "Hello World" Demo in this file.

Hello World under Linux

1. Look at the Section 3.3.7 of SDK 2.0-1703 documentation for installing standalone toolchain:

https://www.nxp.com/docs/en/supporting-information/QORIQ-SDK-2.0-IC-REV0.pdf

2. Use this toolchain for compiling Hello World program.

Each time you wish to use the SDK in a new shell session, you need to source the environment setup script e.g.

 $ . /opt/fsl-qoriq/2.0/environment-setup-ppce6500-fsl-linux

Check information about your cross compiler using the following commands:

echo $CC

or

$CC --version

Check result of "source" command. Use "$PATH" command. The "source" command should add path to gcc compiler.

You should see similar message:

echo $PATH

bash: /opt/fsl-qoriq/1.9/sysroots/x86_64-fslsdk-linux/usr/bin:/opt/fsl-qoriq/1.9/sysroots/x86_64-fslsdk-linux/usr/bin/powerpc-fsl-linux-gnuspe:

Commands for test.c code building:

$CC test.c -o test.elf           // dinamic library

$CC test.c --static -o test.elf             // static library

Hi!,

With this manual (https://www.nxp.com/docs/en/supporting-information/QORIQ-SDK-2.0-IC-REV0.pdf) I have accomplished my compilation, I have changed my Linker configuration in this way:

And finally I get my HelloWorld program compiled with my powerpc-fsl-linux-g++ compiler. Thank you Pavel!!!.

=======================================================================================

Now, in other hand, I'm trying to compile a more complex program. This program needs to include libxml/libglibmm libraries. When I compile that program with a g++ compiler everything is correct, but when I try to compile it with my cross compiler powerpc-fsl-linux-g++ these error are displayed on my console:

¿How I can get such libraries, consistent with powerpc-fsl-linux-g++ compiler?

Thank you very much!!
