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

Thanks

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.

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
