Check whether you get warnings saying that the sqlite3 functions are implicitly declared. If yes then you probably don't have libsqlite3-dev installed.Also, confirm whether you're using sqlite functions or sqlite3 functions. They're not interchangeable.

1. Compile like this: gcc first.c -lsqlite3 -Wall
This will enable all warnings. Will help you find out what may be wrong.
2. You need to check if you have the dev libraries installed or not. To do this you need to check if sqlite-devel package is installed on your system. This is distribution specific. Incase of redhat or its derivatives I would just simple do:
rpm -qa | grep devel | grep sql
this will list all devel packages with sql in it =P

Please format your message properly the next time. It becomes a bit difficult to understand. Anyway, getting back to your question, installation of sqlite devel library depends on your distribution. Here are a few commands for common distributions:
Fedora: yum install sqlite-devel rpm -ivh [RPM FILE NAME]
Debian or debian based distros ( Ubuntu, KUbuntu etc... ): apt-get install sqlite-devel dpkg ( i'm not sure of the syntax )

If you have warnings saying 'implicit declaration of function' then you do not have sqlite3 dev package installed. Simply search for libsqlite3 in your package manager. You'll find two packages; one called libsqlite3 and the other called either libsqlite3-dev or libsqlite3-devel depending on your distro. The dev/devel package is what you need to install. Then follow Dinesh's instructions to install the package.
