Hello Champs,

1. Below is the main.c:

#include <stdio.h>

int main(void)
{
printf("Hello World\n");
return 0;
}

2. Below is the CMakeLists.txt：

cmake_minimum_required (VERSION 2.8)

project (demo)

add_executable(main main.c)

3.Build error：

[linux-devkit]:/home/qingfeng/workspace/ti-processor-sdk-linux-edgeai-am62axx-evm-09_01_00_07/hawk> make

Looks like `cmake` results in the build system trying to attempt a 32-bit build instead of a 64-bit build which the devkit you are using is intended for. If you look at the respective header file you'll see the the inclusion of timesize-32.h is only attempted when __WORDSIZE == 32, so somebody is setting this...

sysroots/aarch64-oe-linux/usr/include/bits/timesize.h-#include <bits/wordsize.h>
sysroots/aarch64-oe-linux/usr/include/bits/timesize.h-
sysroots/aarch64-oe-linux/usr/include/bits/timesize.h-#if __WORDSIZE == 32
sysroots/aarch64-oe-linux/usr/include/bits/timesize.h-
sysroots/aarch64-oe-linux/usr/include/bits/timesize.h-#ifdef _MIPS_SIM
sysroots/aarch64-oe-linux/usr/include/bits/timesize.h-
sysroots/aarch64-oe-linux/usr/include/bits/timesize.h-#if _MIPS_SIM == _ABIO32
sysroots/aarch64-oe-linux/usr/include/bits/timesize.h:#include <bits/timesize-32.h>
sysroots/aarch64-oe-linux/usr/include/bits/timesize.h-#elif _MIPS_SIM == _ABIN32
sysroots/aarch64-oe-linux/usr/include/bits/timesize.h-#include <bits/timesize-n32.h>
sysroots/aarch64-oe-linux/usr/include/bits/timesize.h-#else
sysroots/aarch64-oe-linux/usr/include/bits/timesize.h-#error "Unknown _MIPS_SIM"
sysroots/aarch64-oe-linux/usr/include/bits/timesize.h-#endif
sysroots/aarch64-oe-linux/usr/include/bits/timesize.h-
sysroots/aarch64-oe-linux/usr/include/bits/timesize.h-#else /* _MIPS_SIM is not defined */
sysroots/aarch64-oe-linux/usr/include/bits/timesize.h:#include <bits/timesize-32.h>
sysroots/aarch64-oe-linux/usr/include/bits/timesize.h-#endif
sysroots/aarch64-oe-linux/usr/include/bits/timesize.h-
sysroots/aarch64-oe-linux/usr/include/bits/timesize.h-#elif __WORDSIZE == 64

Cmake has an option to force a target architecture called CMAKE_GENERATOR_PLATFORM, see https://cmake.org/cmake/help/latest/variable/CMAKE_GENERATOR_PLATFORM.html#variable:CMAKE_GENERATOR_PLATFORM

Can you try something like the below and see if this helps and report back here:

cmake . -DCMAKE_GENERATOR_PLATFORM=ARM64

Hello Andreas,

Thank you very much for your great support.

Customer found that it may be caused by a cross-compilation environment that does not support 32-bit compilation:

Set (CMAKE_C_COMPILER) "${TOOLCHAIN_DIR}/x86_64-arago-linux/usr/bin/aarch64-oe-linux/aarch64-oe-linux-gcc")
set (CMAKE_CXX_COMPILER) "${TOOLCHAIN_DIR}/x86_64-arago-linux/usr/bin/aarch64-oe-linux/aarch64-oe-linux-g++")

The search path for header files is set as follows:

set(INCLUDE_PATH) ${CMAKE_SYSROOT}/x86_64-arago-linux/usr/lib/aarch64-oe-linux/gcc/aarch64-oe-linux/11.4.0/include)

Both CMAKE_SYSROOT and TOOLCHAIN_DIR correspond to the following paths:

Sdk installation directory \linux-devkit\sysroots

What needs to be confirmed now focus on below 4 issues:

1.Does the SDK environment only support compilation of 64-bit targets?

2. Is the ubuntu22.04 virtual machine on win10 cross-compile using the compilation tool under x86_64-arago-linux?

3. Is the search path setting for the header files correct? Does he need to confirm the g++ header files search path, otherwise he cannot compile the file for cpp?

4.In order to compile 64-bit targets, how to configure the CMAKE_C_FLAGS and CMAKE_CXX_FLAGS?

Thanks
Regards
Shine

BTW, customer executed cmake according to your advice. It prompts below errors

[linux-devkit]:/home/qingfeng/workspace/ti-processor-sdk-linux-edgeai-am62axx-evm-09_01_00_07/hawk> cmake . -B build -DCMAKE_GENERATOR_PLATFORM=ARM64 -DCMAKE_TOOLCHAIN_FILE=./cmake/toolchains/aarch64_linux_buildroot.cmake
CMake Error at CMakeLists.txt:3 (PROJECT):
Generator

Unix Makefiles

does not support platform specification, but platform

ARM64

was specified.

By reading the link below:
https://cmake.org/cmake/help/latest/variable/CMAKE_GENERATOR_PLATFORM.html#variable:CMAKE_GENERATOR_PLATFORM

It can be concluded that setting the CMAKE_GENERATOR_PLATFORM variable is for specific generators. For example, Visual Studio Generators.

But the problem customer facing now is that the linux-devkit based on sdk builds a cross-compilation environment.

Thanks

Let me find some time to look into this a bit more closely and get back to you.

Hi Shine,

I tried building your CMake-based example in the context of the Linux devkit part of AM62A SDK v9.1 and had no issues. Please see log below. You can see how the aarch64 binary output file 'main' was generated successully.
