Compilation of GDB6.3 [NEDD HELP]

Compilation of GDB6.3 [NEDD HELP]

[Peter Choi]

Hi,

  I compile GDB6.3 from source code. But using this
resultant gdb, 

1. It succeed to load the elf file, but it fail to
execute the elf file. It reported "Don't know thow to
run. Try "help target" ".

2.  Beside, when it loadde my test file (which is a
multihtread program), it does not show up the expected
message "... Using host libthread_db library
"/lib/tls/libthread_db.so.1" " (which I got from older
pre-compiled gdb debugger).

  Please advise what option can  I get wrong in my
compilation of GDB6.3???? Did I need to specify any
special option during compilation????

  Thank you for your attention.

Regards.
Peter Choi

On what target?  Using what configure command?

There's not enough information to help you, sorry.

Hi,

  I compiled GDB6.3 on i386-linux as follow:
  From the source code directory (named gdb-6.3),  
  cd ..
  mkdir build-gdb
  cd build-gdb 
  ../gdb-6.3/configure --target=i386-linux
--prefix=/home/pchoi/work/tools
  make
  make install

  Then I compile GDBserver on i386-linux as follow:
  From the source code directory (named gdb-6.3),  
  cd ..
  mkdir build-gdbserver
  cd build-gdbserver 
  ../gdb-6.3/gdb/gdbserver/configure
--target=i386-linux --prefix=/home/pchoi/work/tools
  make
  make install
  

  Please advise whether it is correct to compile with
multithread remote debugging support???

  Thank you for your attention.

Regards.

Did gdbserver get linked to libthread_db?  Check the build log.

Hi,

  I can't locate any build.log log file, but when I
check my "config.log", I found there was a error
message saying :

configure:1510: checking for libthread_db
configure:1531: gcc -o conftest -g -O2   conftest.c 
-lthread_db 1>&5

configure: failed program was:
#line 1589 "configure"
#include "confdefs.h"

int main() {

; return 0; }


  I wonder what cause this problem with my
"libthread_db" library???? Where should those variable
"ps_XXXX" reside???

  Please advise.

Regards.

Find out where that test came from.  Your configure script is
hopelessly broken; it should be compiling a test file including the
definitions.

Why are you specifying --target=i386-linux if you're trying to build a
native gdb?
