OpenVX 1.3 "typed" constants break build with of OpenVX-based code

[asmorkalov]

Platform: Ubuntu 24.04, GCC 13.3
OpenVX build command: python3 Build.py --os=Linux --conf=Release
Example app:

#include <stdio.h>
#include <VX/vx.h>

int main(int, char**)
{
    printf("OpenVX version: %d\n", VX_VERSION);
#if (VX_VERSION => VX_VERSION_1_0)
    printf("New OpenVX\n");
#endif
    return 0;

Error:

Thanks for opening this issue! It looks like the build error is caused by an incorrect macro in vx.h – the VX_VERSION_1_0 definition uses => instead of >=. A quick fix is to replace => with >=. If you’d like, I can help create a PR with the change. Let me know!
