某天由于某需要，安装tumblr的开源工具memkeys 。但还是一如既往地不是一帆风顺。
在./configure 时出现如下错误信息:
configure.in:14: error: possibly undefined macro: AC_PROG_LIBTOOL If this token and others are legitimate, please use m4_pattern_allow. See the Autoconf documentation. autoreconf: /usr/bin/autoconf failed with exit status: 1
解决办法:yum install libtool (Centos)
apt-get install libtool (Debian)
之后make 出现如下错误:
/lib64/libtinfo.so.5: could not read symbols: Invalid operation
解决办法:export LIBS=/lib64/libtinfo.so.5，然后make clean,make,make install
