I related that to some omit_werror config option and finally to "stfu-kbuild-i-know-better" option (kind of hidden in the code through 6 "OWEx" macros). It is still present on latest code, is it supposed to be viable or some option I shall immediately forget ?

Hi Fred,

In theory systemtap should be generating code that compiles without warnings during the module creation, but in practice we don't check things on ARM as much as we would like.

Could you include the error message output? Was the error messages due to headers outside of systemtap or were they the results of code generated by systemtap?
