General information

• I have run spack debug report and reported the version of Spack/Python/Platform
• I have run spack maintainers <name-of-the-package> and @mentioned any maintainers
• I have uploaded the build log and environment files
• I have searched the issues of this repo and believe this is not a duplicate

[JonathanFrassineti]

I found some hints that the problem is related to cuda@13:, that tries to find the "sm_52" arch (defined as the default one in gcc/config/nvptx folder, I have to check in which file) during the build of gcc-nvptx target but it can't, since its compatibility was removed from version 13 going on.
A workaround to install gcc with cuda@13 is to remove the cuda/bin PATH from the $PATH variable during the build of gcc-nvptx target, like this in the setup_build_environment:

if self.spec.satisfies("@15: ^cuda@13:"):
            path_entry_to_remove = join_path(self.spec['cuda'].prefix,"bin") 
            current_path = os.environ['PATH']
            path_list = current_path.split(os.pathsep)
            path_list = [p for p in path_list if p != path_entry_to_remove]
            os.environ['PATH'] = ""
            os.environ['PATH'] = os.pathsep.join(path_list)

Creating the module, loading it and compiling a simple test file produces the correct results:

#include <stdio.h>
#include <stdlib.h>
#include <openacc.h>

#define N 1000000

int main() {
    float *a, *b, *c;
    int i;

    a = (float *)malloc(N * sizeof(float));
    b = (float *)malloc(N * sizeof(float));
    c = (float *)malloc(N * sizeof(float));

    for (i = 0; i < N; i++) {
        a[i] = i;
        b[i] = i * 2.0f;
    }

    #pragma acc parallel loop copyin(a[0:N], b[0:N]) copyout(c[0:N])
    for (i = 0; i < N; i++) {
        c[i] = a[i] + b[i];
    }

    for (i = 0; i < 10; i++) {
        printf("c[%d] = %f\n", i, c[i]);
    }

    free(a);
    free(b);
    free(c);

    return 0;
}

Compiling with:

gcc -fopenacc -foffload=nvptx-none test_cuda_offload.c -o test_cuda_offload
