[Embedded System] 使用 crosstool 發現找不到 makeinfo 的問題

原文參照下列網址：

http://www.nabble.com/makeinfo-version-checking-to12670622.html

Binutils 2.17 – 2.18 configure script requires texinfo 4.4 or
higher to be installed. The version checking code worked for 4.4
– 4.9 and broke with the latest texinfo 4.11:

if ${MAKEINFO} –version
| egrep ‘texinfo[^0-9]*([1-3][0-9]|4.[4-9]|[5-9])’ >/dev/null 2>&1; then
:
else
MAKEINFO=”$MISSING makeinfo”
fi

The search pattern could be changed to

egrep ‘texinfo[^0-9]*([1-3][0-9]|4.([4-9]|[1-9][0-9])|[5-9])’

to allow two-digit 4.xx subversions.
