error: /utf8.c:463: undefined reference to `libiconv'
# wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz
# tar zxvf libiconv-1.14.tar.gz
# cd libiconv-1.14
# ./configure --prefix=/usr/local/libiconv
# make && make install卸載Centos自帶的git1.7.1:
通過git –version查看系統帶的版本，Cento6.5應該自帶的是git版本是1.7.1
# yum remove git
下載git2.2.1並將git添加到環境變量中
# wget https://github.com/git/git/archive/v2.2.1.tar.gz
# tar zxvf v2.2.1.tar.gz
# cd git-2.2.1
# make configure
# ./configure --prefix=/usr/local/git --with-iconv=/usr/local/libiconv
# make all doc
# make install install-doc install-html
# echo "export PATH=$PATH:/usr/local/git/bin" >> /etc/bashrc
# source /etc/bashrc```
**查看版本號**git --version
git version 2.2.1
