Host GDB suffers a serious problem: pressing backspace (or ^W ^U or any other
"delete" key) results in a plain space being printed instead, making the
command prompt almost completely unusable.
That's because it's using host-ncurses, which embeds a path for the terminfo
database into the library itself. That path ends up being something like
/home/hollisb/buildroot.git/output/host/share/terminfo, which obviously doesn't
generally exist other hosts. ('relocate-sdk.sh' cannot and does not edit
binaries like libncurses.so.6, so doesn't resolve this problem.)
/usr/share/terminfo is a far better path to use, since it almost certainly
exists on the host. Theoretically, it could be from a different ncurses version
with incompatible terminfo database format, but this doesn't seem to be a
problem in practice. (Future patches could address the theoretical problem if
it actually appears in real life.)
This change allows buildroot's host gdb, which uses ncurses 6.x, to work on
RHEL5, RHEL6, and RHEL7, which all provide terminfo from ncurses 5.x.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
