how to install a cross compiler for core-3399-JD4 board?

linux_willow

I am using the Core 3399 JD4 board. I need to setup a compiler PC. I want to be able to compile my code for the 3399 board on this PC and just copy the executable to the 3399 board. I understand that I need to install a cross compiler for the 3399 board in my PC. However, the link at http://wiki.t-firefly.com/en/Cor ... ation-layer-support seems to describe how to install ubuntu in the 3399 board. Is there any cross compiler toolchain available for the 3399 board?

Note: My PC has Ubuntu 18.0.4 LTS installed. It has a intel core i7-9700 CPU.

OK. If you want to run the executable in your PC, you can execute "gcc hello.c -o hello" to get the executable.
If you want to run the executable in your board. There is cross compiler in Linux-SDK. "linux-sdk/prebuilts/gcc/linux-x86/aarch64/gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu/bin/" for 64 bit. Then your can execute "./aarch64-linux-gnu-gcc hello.c -o hello" to get the executable.

thank you for the guidance..I am relatively new to setting up a cross compiler, hence I would like to clear a few concepts here..since I have a Ubuntu PC..I understand that I just need a cross compiler to obtain the executable.. Since we are using the arm gcc..would it be sufficient if I just install an arm cross compiler instead of following all the steps in the http://wiki.t-firefly.com/en/Cor ... ubuntu-firmware-gpt link? what I mean is, there is no need to install the Linux-SDK from the repo since it is also installing the files specific to rockchip device which we are not using?

Yes, if you just want to obtain the executable, just install an arm cross compiler is OK.
