20:35 <nrb> hi fche, i have made it to run with 5.7.7

20:35 <fche> hi nrb

20:36 <nrb> although i need to test against the newest kernel too (rc versions), any tips on this besides compiling systemtap yourself?

20:36 <nrb> gcc version is the same

20:36 <fche> sorry not fresh on context - what's working for you?

20:36 <nrb> i am trying to make it run

20:36 <nrb> systemtap has been compiled by me today

20:37 <nrb> i compiled the linux kernel, ran make install, make headers_install, make modules_install, restarted all, now i try to run a test

20:37 <nrb> but man error::pass4

20:37 orivej has quit [Ping timeout: 256 seconds]

20:37 <fche> ok, may be able to help with a more complete error message

20:37 <fche> or

20:37 orivej_ has joined #systemtap

20:37 <fche> try stap -r /path/to/kernel/build/tree [...]

20:37 <nrb> lemme try recompile the kernel completely

20:38 <fche> (shouldn't be necessary)

20:38 <nrb> ok running this line

20:38 <nrb> btw i find systemtap to be very helpful, great tool, but it can be a pain in the ass to install it

20:38 <nrb> always had problems no matter which kernel

20:41 <nrb> alright whatever i think i will just go the save way now, redownload the kernel, reconfigure it, recompile, if i am assured of this and it won't work, i might come back

20:41 <nrb> thank you fche for helping out tho

20:41 <fche> np

20:41 <fche> surprised you need to build kernels so much .... that is unless you are working ON the kernel itself :)
