[Serusers] How to build in SER modules statically for profiling?

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!
