how to build native GDB on mips64 linux ?

["guijian" <guijian@ict.ac.cn>]

Hi,

Did someone successfully build any native GDB version( 5.3, 6.0 or 6.1) on mips64 Linux ?

I build GDB 6.1 with "./configure mips64-linux; make" with the native gcc2.96 and native make3.79. while it built successfully, the resulting binary hung when print symbol or set breakpoint, like this:

  (gdb) b main
  ( hung here. have to be killed to exit.)

   If the debugged file is executed instead, results will be:
  (gdb) r
  Starting program: /home/gj/work/matrix_rev 
  Program received signal SIGTRAP, Trace/breakpoint trap.
  0x045f652010002fd0 in ?? ()
  (gdb) bt
  #0  0x045f652010002fd0 in ?? ()
  ( hung here. have to be killed to exit.)

Other commands such as bt, print could not return either. I've tried "./configure mips64el-linux; make" and other, also tied other versions of GDB, but results are same. Native GDB is a must in my project. 

Would you give some advice ?

Best regard.
