cross compile gdbserver to mips give me an error
 
Hi, I'm trying to cross compile gdb for mips platform but Im getting an error, so after

Code:
:~/Downloads/gdb-7.12/gdb/gdbserver$ ./configure --host=mips-linux
I'm getting

Code:

How can I resolve this error ?

Go up one directory and use grep -r to search for the missing define:

$ cd ..
$ grep -r FPR_BASE *
...
mips-linux-tdep.h:#define FPR_BASE 32

This header is not included in linux-mips-low.c. Search for this header file in your build directory. There may be an error including it in another header which is included.

So I searched for it and sure enought there it is so what now ? should I add (but what?) in linux-mips-low.c ? Here is mine search
Code:
$ grep -r FPR_BASE *
