<DIV><FONT face=宋体 size=2> Thank you for your kind help. However,my problem
is to profile the shared libraries rather than to profile forking
processes. gprof can not generate any information about these shared libraries,
and i also seems problem when using sprof, which is said to be able to offer
profiling statistics about dynamic loaded libraries.</FONT></DIV>
<DIV><FONT face=宋体 size=2> So, I think another way is to
build these modules statically, but don't know how to. So can anyone help me
with that? thanks for your time!</FONT></DIV>

invoking monstartup() in each child process <BR> since the

childs including timer and fifoserver. If you are <BR> only
interested in certain worker processes you can cut down <BR> the
resource impact by selectively activating profiling. <BR>- enable
profiling in Makefile.defs <BR> - Set both -DPROFILING and
PROFILE=-pg <BR>- compile and deploy as usual <BR>- Before starting SER
using your standard init script you need <BR> to set an
environment variable that acts as a prefix to all <BR> profiling
data files. If you don't set it you'll only get one <BR> file for

per-process statistics using <BR> $ gprof /usr/sbin/ser
testrun.<PID> <BR>- If cummulative statistics are what you are

to create a new gmon.out which contains statistics over all <BR>
processes. <BR><BR>I have yet to fully analyze the results.

<BLOCKQUOTE cite=midDz939188869785.28566@mail4 type="cite"><PRE wrap="">Hi, all!
I am currently involved in a research work which aims at optimizing the SIP stack, and we chose SER -0.9.6 as our researching platform. we need to profile SER to find out which part(parser? network? transactions? ) consumes the most CPU cycles. However, tools like gprof and Intel Vtune's sampling tool can not show any information about the functions in dynamically loaded modules, such as tm, registrar. So, a possible solution seems to build in these modules into the core statically.
I tried to do what the INSTALL doc says, compling with the following command:"make static_modules=tm PROFILE=-pg all", the final part of the result shows:
......
make[1]:***[callid.o] Error 1
make[1]: Leaving directory '/....../SER/ser-0.9.6/modules/tm'
gcc -Wl,-02 -Wl, -E -pg action.o crc.o .....modules/tm/dlg.o, modules/tm/h_table.o .....modules/tm/uac_unixsock.o -
gcc: modules/tm/callid.o:No such file or directory
gcc: modules/tm/h_table.o:No such file or directory
...
gcc: modules/tm/uac_unixsock.o:No such file or directory
make: **[ser] Error 1
And if I proceed to type: make install
the result shows:
sr_module.o(.text+0xbc): In function 'register_builtin_modules':
/.../ser-0.9.6/sr_module.c:89: undefined reference to 'tm_exports'
collect2:ld returned 1 exit status
make: ***[ser] Error 1
I am working with SER 0.9.6
And the linux kernel used in my machine is:
Linux 2.6.9-22.ELsmp
the OS used is Redhat 9
if anyone has tried the same thing or knows the solution, please let me know.Thanks very very much!
