持續探索中

有時在一些unix-like環境安裝東西的時候會出現底下的訊息

WARNING: `makeinfo’ is missing on your system. You should only need it if
you modified a `.texi’ or `.texinfo’ file, or any other file
indirectly affecting the aspect of the manual. The spurious
call might also be the consequence of using a buggy `make’ (AIX,
DU, IRIX). You might want to install the `Texinfo’ package or
the `GNU make’ package. Grab either from any GNU archive site.

網路上有查到一些workaround的做法

用編輯器打開configure檔, 搜尋一下片段的相關字

把原本-的那行改成+的那行

 # For an installed makeinfo, we require it to be from texinfo 4.4 or
 # higher, else we use the "missing" dummy.
 if ${MAKEINFO} --version \
-       | egrep 'texinfo[^0-9]*([1-3][0-9]|4\.[4-9]|[5-9])' >/dev/null 2>&1; then
+       | egrep 'texinfo[^0-9]*(4\.([4-9]|[1-9][0-9])|[5-9]|[1-9][0-9])' >/dev/null 2>&1; then
 :
 els
 MAKEINFO="$MISSING makeinfo"

原因跟textinfo這個套件的版本有關, 把texinfo更新一下就可以解決
