Gprofiling Missing gcrt1.o Object file

Gprofiling Missing gcrt1.o Object file

Hi,
          I am trying to profile (gprof profiling) my application which is
cross-compiled for the target Mips system [*Linux Mips 2.6.8.1]* and UCLIBC
*uclibc-crosstools_gcc-3.4.2_uclibc-20050502. *As far as i searched in the
google i could see a requirement of gcrt1.o object file for the mips linux
which is not available on the mips-linux.

          I tried linking with crt1.o but i could not get accurate profiling
information. I came to know that gcrt1.o is required to get the accurate
information. Where can i get the so called gcrt1.o for Mips-linux.

Thanks & Regards,
Viswanath.

gcrt1.o should be part of the C library (uClibc in your case).  If it is 
  not providing it, it is a bug in uClibc.

Actually I don't even know it uClibc supplies a gcrt1.o.  Our build 
doesn't seem to have one.  If you build a glibc based system, that would 
give you a working gcrt1.o

am planning to cross compile gcrt1.c (source files )with mips-linux-gcc.
Will let you know the output.

Thanks
