GDB on ARM

GDB on ARM

[Ashoka K]

Hi,

I am trying to use Valgrind on ARM target. The Valgrind intrenally
supports GDB. To connect to the Valgrind-GDB (i.e, gdbserver) i need
the GDB (host) also to run on arm target. i.e GDB and GDServer both
built with host=arm-linux-gnueabi.

I downloaded latest GDB7.7 and able to build gdbserver, but during
building GDB with host=arm-linux-gnueabi I got the below error. I
searched all over and found that to install libncurses package. I did
that but it didn't work.

My system:
Build-host: Ubuntu-Lucid (10.04) on Virtual-machine with
arm-linux-gnueabi tool chain
Target: ARM OMAP

checking for library containing gethostbyname... none required
checking for library containing socketpair... none required

Please help.

You can check the config.log file to see the exact command line used by
configure to detect the presence of libtermcap.

You have to cross compile ncuses for arm at first.

You still need to make sure your installed libncurses can be found
during configure.  I build native mips gdb on x86-linux and installed
ncurse to MIPS_NCURSES.  I pass the following to configure

CFLAGS="-I$MIPS_NCURSES/include -L$MIPS_NCURSES/lib"
