Instalando Toolchain/SDK

Instalando o toolchain tdx-xwayland-glibc-x86_64-b2open-core-image-armv8a-colibri-imx8x-toolchain-7.3.0.sh:

Executar no HOST

cd tmp/deploy/sdk/

./tdx-xwayland-glibc-x86_64-b2open-core-image-armv8a-colibri-imx8x-toolchain-7.3.0.sh

Saída do comando acima:

TDX Wayland with XWayland SDK installer version 7.3.0
=====================================================
Enter target directory for SDK (default: /opt/tdx-xwayland/7.3.0):

Digite o caminho a seguir para instalação do Toolchain/SDK:

Executar no HOST

~/treinamento/sdk/7.3.0

Como deve ficar configurado:

TDX Wayland with XWayland SDK installer version 7.3.0
=====================================================
Enter target directory for SDK (default: /opt/tdx-xwayland/7.3.0): ~/treinamento/sdk/7.3.0
You are about to install the SDK to "/home/b2open/treinamento/sdk/7.3.0". Proceed [Y/n]?

Saída esperada:

TDX Wayland with XWayland SDK installer version 7.3.0
=====================================================
Enter target directory for SDK (default: /opt/tdx-xwayland/7.3.0): ~/treinamento/sdk/7.3.0
You are about to install the SDK to "/home/b2open/treinamento/sdk/7.3.0". Proceed [Y/n]? Y
Extracting SDK..............................................................................................................................................................done
Setting it up...done
SDK has been successfully set up and is ready to be used.
Each time you wish to use the SDK in a new shell session, you need to source the environment setup script e.g.
 $ . /home/b2open/treinamento/sdk/7.3.0/environment-setup-armv8a-tdx-linux

Preparando o ambiente com . /home/b2open/treinamento/sdk/7.3.0/environment-setup-armv8a-tdx-linux e fazendo uma aplicação em C para compilação-cruzada:

Executar no HOST

cd ~/treinamento/yp/poky/build-toradex/

. /home/b2open/treinamento/sdk/7.3.0/environment-setup-armv8a-tdx-linux

Verificando ambiente após executar comando para preparar o terminal para utilizar o toolchain gerado e instalado:

Executar no HOST

echo $CC

Saída esperada:

aarch64-tdx-linux-gcc -march=armv8-a+crypto -mbranch-protection=standard -fstack-protector-strong -O2 -D_FORTIFY_SOURCE=2 -Wformat -Wformat-security -Werror=format-security --sysroot=/home/b2open/treinamento/sdk/7.3.0/sysroots/armv8a-tdx-linux

Executar no HOST

echo $CXX

Saída esperada:

aarch64-tdx-linux-g++ -march=armv8-a+crypto -mbranch-protection=standard -fstack-protector-strong -O2 -D_FORTIFY_SOURCE=2 -Wformat -Wformat-security -Werror=format-security --sysroot=/home/b2open/treinamento/sdk/7.3.0/sysroots/armv8a-tdx-linux

Compilando um programa em C

Criando o arquivo main.c e adicionar o código abaixo:

#include <stdio.h>

int main(void) {

    printf("Ola Mundo!\n");
    return 0;
}

Compilando e verificando o binário gerado:

Executar no HOST

$CC main.c -o main

file main

Saída esperada:

main: ELF 64-bit LSB shared object, ARM aarch64, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-aarch64.so.1, BuildID[sha1]=ee34038b5c9918707c3c506bdc0fa4b01dd1f47b, for GNU/Linux 5.15.0, with debug_info, not stripped

Compilando um projeto C++ de um repositorio

Testando o toolchain com o software socketcan-cpp:

Executar no HOST

cd /tmp

git clone https://github.com/siposcsaba89/socketcan-cpp

Acessando o diretório do projeto e executando o comando cmakee na sequência make:

Executar no HOST

cd socketcan-cpp/ 

mkdir build

cd build/

cmake ../

Saída:

CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required):
  Compatibility with CMake < 3.5 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to tell
  CMake that the project does not need compatibility with older versions.
