I recall my previous mail about cross-compilation. When i did exactly what is recommended, I managed to cross-compile. The unexpected issue appeared when I run wvalgrind myappw: FATAL: kernel too old My kernel is 2.6.37 and seemed to be ok. Is it final or can I do something further? Old Valgrind version, for example?
Stop. Give it up. Find something else to do. If this is your job, then find a new job as soon as you can, so that you can quit this insanity.
Even OpenWRT runs Linux 5.11. It seems likely that your environment is some ARM (v4 or v5) embedded system that has an app with a horrendous bug that you are trying to find and fix. Trying to do this natively, running such an old kernel and probably with severely limited RAM, is insane. Get a 4GB or 8GB Raspberry Pi running a current Debian or Fedora Linux, and debug the app there. The Pi has GPIO, USB, Ethernet, camera, and dot-matrix display interfaces. If there are other sensors on your device, then you should have hardware adapters so that they can use USB interfacing, so that you *can* use a Pi as a real-time development environment. If your management won't spend the time or money to make or procure such adapters for the sensors, then there is *NO* hope. _______________________________________________ Valgrind-users mailing list Valgrind-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/valgrind-users
