Hi guys,

I am new to c++ and eclipse and I have come to this problem. I dont know how corectly link sqlite3 api to my c++ project in eclipse.

I am trying to compile and execute simple example of connecting to database (from tutorial), but it ends with these errors:

undefined reference to `sqlite3_open'
undefined reference to `sqlite3_errmsg'
undefined reference to `sqlite3_close'

I am using ubuntu and I already installed libsqlite3-dev. I am able to create and manage db in command line, so I know it is working.
I also know that most probably I have to change theese settings:

Properties>>C/C++ Build>>Settings>>GCC C++ Compiler >> Includes
Properties>>C/C++ Build>>Settings>>GCC C++ Linker >> Libraries

but I dont know how exactly. Could anyone help me please?

Thanks

I have followed instructions for linux and got rid off errors I had, but
now I have this one:

make all 
Building target: SQLiteTest
Invoking: GCC C Linker
gcc -L/usr/include/ -o "SQLiteTest"  ./hello.o   -lsqlite3.h 
/usr/bin/ld: cannot find -lsqlite3.h
collect2: error: ld returned 1 exit status
make: *** [SQLiteTest] Error 1

I checked /usr/include/ and there really is sqlite3.h file.
Could you help me with that please?

Thank you.

You are confusing a header file with a library. You don't pass header
files to the linker. Go back to the Libraries settings for the linker
and give the library name (most likely sqlite3) instead of the header
file name.
