Running the binary using qemu-aarch64 results in segmentation fault error. ``` $ qemu-aarch64 -L /home/vsts/qnx710/target/qnx7/aarch64le ./hello-world qemu: uncaught target signal 11 (Segmentation fault) - core dumped Segmentation fault (core dumped) ``` We also tried Ubuntu Jammy which has qemu-aarch64 v6.2.0 but got the same error. Can you tell us how we can emulate the binary using QEMU emulator that is built for QNX on x86_64 platform? Any help would be much appreciated. Steps to reproduce: 1. Download QNX SDP from QNX software center https://www.qnx.com/download/group.html?programid=29178. 2. Write a simple hello world program. ``` #include int main(void) { return printf("Hello World!"); } ``` 3. Source QNX SDP to set some environment variables. `$ source ./qnx710/qnxsdp-env.sh` 4. Compile using the QNX compiler. `$ qcc -Vgcc_ntoaarch64le -o hello-world hello-world.c` 5. Running the binary as it is results to: ``` $ ./hello-world aarch64-binfmt-P: Could not open '/usr/lib/ldqnx-64.so.2': No such file or directory ``` 5. Running using QEMU emulator results to segmentation fault. ``` $ qemu-aarch64 -L /home/vsts/qnx710/target/qnx7/aarch64le ./hello-world qemu: uncaught target signal 11 (Segmentation fault) - core dumped Segmentation fault (core dumped) ```
