[Buildroot] GNU Bison package

[Buildroot] GNU Bison package

[Doha Ehab]

Hello,
 I have generated uclibc toolchain using buildroot-2017.02-rc3. I am trying
to use it to cross compile Gnu GCC for Android. I have checked flex and
gettext from target packages-> development tools but I cannot find bison
library and I always get this error:

/home/Desktop/gcc_5/missing bison -y --name-prefix=__gettext --output
plural.c ../.././intl/plural.y

WARNING: 'bison' is missing on your system.
         You should only need it if you modified a '.y' file.
         You may want to install the GNU Bison package:

Why use a release candidate ? If you're using 2017.02, please use the
latest 2017.02.x release, currently 2017.02.9.

We do not support building gcc for the target, so I'm not sure how
Buildroot will help you with this.

There is not enough context here to help you. When does this happens?
During the build of which package ? Does this happens during a complete
rebuild (i.e "make clean all") ?

Or perhaps this happens when you try to manually build gcc outside of
Buildroot ? If so, I'd say you're on your own, and if bison is missing,
well, just build host-bison, and add output/host/usr/bin to your PATH.

Best regards,

Thomas
