I’ve jetson Xavier NX board with me on which I’ve wrriten a piece of code. I’ve seen this [container](https://catalog.ngc.nvidia.com/orgs/nvidia/containers/jetpack-linux-aarch64-crosscompile-x86) which cross compiles cuda program from x86 to aarch64. But is the reverse possible i.e., is their a toolchain through which I can cross compile to x86 as I want to send a binary to someone on x86 machine. If there’s no toolchain available, is their any other way to send my working binary as I don’t wanna share my src code. ---

Hi, Unfortunately, we don’t support such a use case. Are you able to compile the source on an x86 device before sharing it? Thanks. ---

Thanks!! I’ve 2 versions of my code. version 1: It is a simple cuda program which takes in a raw image file, applies debayer on it using GPU (my cuda program) and saves the file back. version 2: It uses Libargus and EGL to capture raw image stream, apply debayer on GPU and display the output in result window. I’m able to compile both versions 1 and 2 on aarch64 Xavier NX Jetson Board. I’m able to compile version 1 on x86 but can’t compile version 2 as I don’t have argus, EGL etc. libraries on my x86 as of now. Questions: 1. Is there a way we can use libargus on x86 or is argus library specifically made for jetson boards? 2. This is purely for learning purposes as I already have aarch64 binary of version 2 with me. I’m trying to cross compile version 2 from x86 to aarach64 (Even though I already have version 2 compiled on my jetson board but I’m testing weather I can also cross-compile version 2 from x86 using the cross compiler container). Inside the cross compiler container there are aarch64 libraries available i.e., argus, EGL libraries available inside the targetfs directory. Can I use those libraries inside my container along with my local x86 nvcc compiler and aarch64-linux-gnu- cross compiler to cross-compile version 2 for aarch64. Something like this: `/usr/local/cuda/bin nvcc -ccbin aarch64-linux-gnu- -L /l4t/targetfs/usr/lib/aarch64-linux-gnu` I’m asking question 2 because I’m able to compile the jetson\_multi\_media\_samples using the commands given in the container documentation: `cd /l4t/targetfs/usr/src/jetson_multimedia_api` `export CROSS_COMPILE=aarch64-linux-gnu- ` `export TARGET_ROOTFS=/l4t/targetfs/ ` `make` But the documentation doesn’t tell how to compile the argus samples inside the jetson multimedia API directory (`/l4t/targetfs/usr/src/jetson_multimedia_api/argus`). argus directory has a CMakeLists.txt file in it but no aarch64\_toolchain.cmake, hence I can’t cross compile argus samples or the argus camera app ---

Hi, Argus is a Jetson-specific library, so it is not available on the desktop environment. jetson\_multimedia\_api doesn’t support x86 environment either. Thanks. ---
