Hi, I want to use Callgraph / Systemtap on Debian Squeeze (AMD64) with Eclipse LinuxTools / CDT. I have installed SystemTap from the Debian Squeeze repository (according to http://sourceware.org/systemtap/wiki/SystemtapOnDebian) If I run the "helloworld" example that comes with the package I get the following output: jkr@panoramix:/usr/share/doc/systemtap-doc/examples/general$ stap -v helloworld.stp Pass 1: parsed user script and 68 library script(s) using 49940virt/20896res/1756shr kb, in 240usr/20sys/272real ms. Pass 2: analyzed script: 1 probe(s), 1 function(s), 0 embed(s), 0 global(s) using 50468virt/21572res/1964shr kb, in 0usr/0sys/6real ms. Pass 3: using cached /home/jkr/.systemtap/cache/77/stap_77409a90ca59fb213b8be2d6b92e0e46_710.c Pass 4: using cached /home/jkr/.systemtap/cache/77/stap_77409a90ca59fb213b8be2d6b92e0e46_710.ko Pass 5: starting run. staprun:send_a_relocation:331: ERROR: reloc name too long: .gnu.linkonce.r._ZN6AsicNII18ucode_class_caymanE23NITilingModeLookupTableE: No such file or directory staprun:send_a_relocation:331: ERROR: reloc name too long: .gnu.linkonce.r._ZTV15WritebacksBlockIN11mmEngineUVD16WRITEBACKS_BLOCKEE: No such file or directory staprun:send_a_relocation:331: ERROR: reloc name too long: .gnu.linkonce.r._ZTV15WritebacksBlockIN17mmEngineR600_IDCT16WRITEBACKS_BLOCKEE: No such file or directory ... [ deleted lots of lines with the same kind of error ] ... hello world Pass 5: run completed in 30usr/160sys/258real ms. All the functions in the errors are from my proprietary closed source Radeon videocard driver (fglrx). For that driver I do not have a debug version available. It appears that something that is called "dkms" is used to actually compile and install (some parts of?) that driver, but to be honest I do not have any further knowledge of that mechanism. Can I make SystemTap work in this case or do I actually need debug versions for all modules? As I am not interested in any video performance or callgraphs, can I get rid of those errors somehow?
