Hello,
I work on a library who have some offloading with openMP. I'm stuck with an issue, on every offloading section.
My error in GDB always consern #pragma with offload:
Libomptarget error: Host ptr 0x00007ffff7a05ab0 does not have a matching target pointer.
Libomptarget error: Consult https://openmp.llvm.org/design/Runtimes.html for debugging options.
qmckl_ao.c:6267:5: Libomptarget fatal error 1: failure of target construct while offloading is mandatory

In fact all my pointers has been declarated with omp_target_alloc and look's to work (Just by checking the adr). I can compile and execute my code on NVIDIA GPU (A100 and laptop GPU).
I work on an W6800, and I can compile and execute simple sample of code with openMP.
Do you have any ideas why my code doen't work?
Thank's in advance for your answers !
