Fabrice Fontaine 03c148c8de package/bird: needs autoreconf
Since the bump to version 2.0.8 in commit
f5906644b4, bird uses a home-grown "GNU Autoconf
2.69e" instead of standard autoconf 2.69 to generate the configure
script. This fork seems to generate incorrect code: it uses

ac_test_CFLAGS=${CFLAGS+y}

to remember if CFLAGS was saved, while standard autoconf uses

ac_test_CFLAGS=${CFLAGS+set}

The configure.ac code itself, however, uses

if test "$ac_test_CFLAGS" != set ; then

to check if CFLAGS was overridden.

Thus, Buildroot's CFLAGS are not taken into account and this leads to
the following build failure:

checking for glob.h... no
configure: error: glob.h not found.

This build failure is raised because -g0 and -g are both passed to gcc:

configure:5207: checking for glob.h
configure:5230: /data/buildroot-autobuilder/instance-0/output-1/host/bin/mips64el-linux-gcc -o conftest -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64  -Os -g0  -pthread -fno-strict-aliasing -fno-strict-overflow -flto -Wall -Wextra -Wstrict-prototypes -Wno-parentheses -Wno-pointer-sign -Wno-missing-field-initializers -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64  -pthread -flto=4 -g conftest.c  >&5
/data/buildroot-autobuilder/instance-0/output-1/host/opt/ext-toolchain/bin/../lib/gcc/mips64el-buildroot-linux-uclibc/8.4.0/../../../../mips64el-buildroot-linux-uclibc/bin/ld: /tmp/ccDboxph.ltrans0.ltrans.o:(.debug_info+0x2a): undefined reference to `conftest.c.0943dc99'
/data/buildroot-autobuilder/instance-0/output-1/host/opt/ext-toolchain/bin/../lib/gcc/mips64el-buildroot-linux-uclibc/8.4.0/../../../../mips64el-buildroot-linux-uclibc/bin/ld: /tmp/ccDboxph.ltrans0.ltrans.o:(.debug_info+0x2f): undefined reference to `conftest.c.0943dc99'

-g0 is passed by buildroot and -g is passed by bird if
$ac_test_CFLAGS" != set (since version 2.0.7 and
cc95b4594a)

To fix this, we can simply run autoreconf and generate a correct
configure script.

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 OFTC IRC.
