Per the kselftests documentation[1], the gen_tar target is used to package the tests to run "on different systems". But what if the different system has different libraries/library versions? Wouldn't it be a problem?
...
While the current approach can work when the selftests rely solely on shell scripts(cpufreq, kexec), those who compile userspace binaries (cgroup, alsa, sched, ...) may not work.
Am I missing something? Is gen_tar only meant to copy the tests to be run on systems with the same libraries or with the libraries with the exactly the same version?
gen_tar was originally intended (I believe) for developers doing cross-compilation. The SDK used for cross-compilation of the executables should handle issues such as library versions (and of course, CPU architecture and endian-ness).
I've never done cross-compilation for the same architecture, so I don't know how that would work, but I presume there is some way to compile code for another system with the same architecture but different libraries. -- Tim
