No matter how I try, I can't seem to get a library profile from sprof on CentOS5. Does anyone know if sprof actually works on CentOS5? I'd be very interested to hear if anyone is using it successfully. At the moment I'm trying something like this to get the dump: LD_LIBRARY_PATH=. LD_PROFILE=libmy.so ./mymain where libmy.so is the library I want to...

Hi, I am working on an R package which includes some C routines. I would like to profile the C routines (built with GCC under Debian Linux). I tried running R with LD_PROFILE=/path/to/C/library.so R and executing functions that would invoke the code therein. The code takes about twice as long to run with LD_PROFILE set than without, so I am guessing that profiling is taking place. However,

...quot;package.Rcheck" and the shared objects and example code of the package are in there. Can I force R to use those *.so files instead of the ones in /usr/lib/R ? I also wonder "what is wrong with gprof? In the Writing R Extensions manual, it describes "oprofile" and "sprof" for Linux. I will try them, but they are unfamilar to me. I've used gprof in the past in C projects, and it is a pretty painless thing to add a compiler flag -pg, run the program, and then review gmon.out. The Writing R Extensions manual does not mention gprof in its section on Linux, b...

Hi all, Is anyone using oprofile? I'm getting segfaults from opreport at the moment, and I'm not sure if it is opreport, or just me. In case it is something just plain daft I am doing, here is how it goes: opcontrol --reset opcontrol --setup --no-vmlinux opcontrol --start ... now I run my program, /tmp/myprog ... opcontrol --dump opcontrol --shutdown then I run, opreport -l
