WARNING: 'makeinfo' is missing on your system.
You should only need it if you modified a '.texi' file, or
any other file indirectly affecting the aspect of the manual.
You might want to install the Texinfo package:
<http://www.gnu.org/software/texinfo/>
The spurious makeinfo call might also be the consequence of
using a buggy 'make' (AIX, DU, IRIX), in which case you might
want to install GNU make:
<http://www.gnu.org/software/make/>
Makefile:486: recipe for target 'gdb.info' failed
解决方案为：apt-get install texinfo
