Depending on the configuration, the cpp output may contain the string 'yes'
in a comment if built under a path containing 'yes', confusing the _AIX
test:
${CROSS}-cpp conftest.h
\# 1 "conftest.h"
\# 1 "<built-in>"
\# 1 "<command-line>"
\# 31 "<command-line>"
\# 1 "/home/peko/source/buildroot/output-yes/host/x86_64-buildroot-linux-gnu/sysroot/usr/include/stdc-predef.h"
\# 32 "<command-line>" 2
\# 1 "conftest.txt"
If misdetected, the configure script adds -lc128 to LIBS, causing the
AC_CHECKS_FUNCS check for stat64 to fail, which in turn causes compilation
errors about redefinition of symbols:
In file included from ./src/include/pv-internal.h:9:0,
from src/pv/file.c:5:
./src/include/config.h:76:18: error: redefinition of 'struct stat'
# define stat64 stat
^
Fix it by only matching on 'yes' on a line by itself.
As pv doesn't cleanly autoreconf (it doesn't use automake and configure.in
is located in subdir), instead directly patch configure.

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
