Running cross-compiled binary using QEMU results in segmentation fault error

[Asad Javed]

Hi,

We have cross compiled a simple hello world program for QNX SDP 7.1.0 on Ubuntu Focal x86_64. Running the binary using qemu-aarch64 results in segmentation fault error. The qemu-aarch64 version is 5.2.0.

Steps:

1. Source QNX SDP to set some environment variables.

     source ./qnx710/qnxsdp-env.sh

2. The hello-world.c file:

     #include <stdio.h>

     

     int main(void) {

         return printf("Hello World!");

     }

3. Compiled using the QNX compiler.

      $ qcc -Vgcc_ntoaarch64le -o hello-world hello-world.c

4. 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)

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 that is built for QNX on x86_64 platform using QEMU emulator? Any help would be much appreciated. Thanks

Thanks & Regards,
