sqlite 在麒麟下安装、编译

sqlite 在麒麟下安装

1、登录官方网站，查看下载地址，下载，安装

https://www.sqlite.org/download.html

$ wget http://www.sqlite.org/sqlite-3******.tar.gz
$ ./configure
$ make
$ sudo make install

2、验证

$ sqlite3
$ sqlite

3、程序验证

首先要编译好
sqlite的库文件 :
      libsqlite3.a  libsqlite3.la  libsqlite3.so  libsqlite3.so.0  libsqlite3.so.0.8.6  pkgconfig
可执行文件 : 
      sqlite3

本次测试：
      sqlite3的库文件目录是：/usr/local/lib
      可执行文件 sqlite3 的目录是： /usr/local/bin
      头文件 sqlite3.h 的目录是： /usr/local/include

用ls命令查看如下：
[root@localhost config]# ls /usr/local/lib
libclamav.a         libclamunrar_iface.a         libclamunrar.so        libsqlite3.so
libclamav.la        libclamunrar_iface.la        libclamunrar.so.5      libsqlite3.so.0
libclamav.so        libclamunrar_iface.so        libclamunrar.so.5.0.3  libsqlite3.so.0.8.6
libclamav.so.5      libclamunrar_iface.so.5      libmstring.so          pkgconfig
libclamav.so.5.0.3  libclamunrar_iface.so.5.0.3  libsqlite3.a
libclamunrar.a      libclamunrar.la              libsqlite3.la

此目录下包含库文件：
      libsqlite3.a  libsqlite3.la  libsqlite3.so  libsqlite3.so.0  libsqlite3.so.0.8.6  pkgconfig
