这个地址是下载 sqlite3的源码的地址:http://sqlite.org/download.html
到上面下载最新的源码,我开始的时候没有下载最新的源码,导致sqlite3的API用不了,非常的郁闷搞了两天终于知道,用sqlite最新的版本就解决了这个问题。
下载了源码在 虚拟机里面 新建一个目录 存放 安装的内容。
1.mkdir /home/cys/900
2 tarxvzf sqlite-autoconf-3080900.tar.gz
3.cdsqlite-autoconf-3080900
4../configure --prefix=/home/cys/900 --disable-tcl —host=arm-hismall-linux
5.make
6.make install
7.编译程序的时候 要用到头文件和库文件 arm-hismall-linux-gcc -o test test.c -lsqlite3 -L/home/cys/900/lib -I/home/cys/900/include
