安装一下sqlite sqlite3
  1. sudo apt-get install sqlite sqlite3

  3. $ sqlite -version
  4. 2.8.17


  7. $ sqlite3 -version
  8. 3.16.2 2017-01-06 16:32:41 a65a62893ca8319e89e48b8a38cf8a59c69a8209


  11. $ whereis sqlite
  12. sqlite: /usr/bin/sqlite /usr/share/man/man1/sqlite.1.gz
  13. $ whereis sqlite3
  14. sqlite3: /usr/bin/sqlite3 /usr/share/man/man1/sqlite3.1.gz
复制代码
重新编译，问题依旧。

安装　libsqlite3-dev
sudo apt-get install libsqlite3-dev

问题依旧。

本地查看安装情况
locate libsqlite3.so
/usr/lib/x86_64-linux-gnu/libsqlite3.so.0
/usr/lib/x86_64-linux-gnu/libsqlite3.so.0.8.6
发现默认是安装的64位的，要安装下32位的


用下列命令查找３２位包

aptitude search libsqlite3

安装

sudo apt-get install libsqlite3-dev:i386

编译成功。
