The output of the profiler is saved as follows ==================================. ls -lrt /tmp/mxed_profiler_3 -rw-r--r-- 1 admin root 666921 Feb 26 13:02 /tmp/mxed_profiler_3 When I run, pprof --gv --lines --nodecount=200 --nodefraction=0.0005 /opt/tms/bin/mxed /tmp/mxed_profiler_3 I get only couple of nodes and the number of samples says "8". So it means, may be only 8 samples were taken during the run of over 3 or 4 minutes? ~Rajesh.B On 2/26/07, Rajesh Balamohan <[EMAIL PROTECTED]> wrote:
Hi Arun and David, I tried google profiler in 64 bit. It works fine and generates the output. However, if its a multi-threaded application, it just gives it for main thread alone. Are there any known issues in using google prof with 64 bit in multi threaded applications? ~Rajesh.B On 2/26/07, Rajesh Balamohan <[EMAIL PROTECTED]> wrote: > > > CFLAGS=-fPIC ./configure > make CFLAGS=-fPIC LDFLAGS=fPIC > make CFLAGS=-fPIC LDFLAGS=fPIC check > make CFLAGS=-fPIC LDFLAGS=fPIC install > > This installed libunwind without any issues.
