What are the necessary libraries to compile a cross gdb?

What are the necessary libraries to compile a cross gdb?

[colin]

Hi all,
Our MIPS platform contains only Linux, uClibc, and Busybox.
When I cross-compiling gdb, it seems to lack some libraries to successfully
compile it.
Can I use --disable-* to omit all of these libraries? What are the
necessaries libraries?

Regards,
Colin

First, let me make sure I understand what you're trying to do.  You're
not trying to build a GDB that runs directly on your MIPS platform;
you're trying to build a GDB that runs somewhere else but debugs
programs that are running on your MIPS platform.  Right?  (So you're
not "cross-compiling" GDB; that would mean you were building a gdb
executable which you expected to run on some other platform.  Rather,
you're building GDB as a cross-platform debugger.)

What are the error messages you're getting?  Give us a transcript of
the relevant part of your failing compilation, with context.

From the other direction, to cross compile GDB, you need ncurses or
some other library providing a termcap interface.

Sorry, my poor English makes you misunderstand my question.
I want to cross-compile a MIPS gdb on an x86 machine. Target and host are
both MIPS.
To prepare a library of MIPS is not easy, so I would like to omit all
unnecessary libraries to compile a gdb.

Thanks and regards,
Colin

Try building ncurses first, then.
