The documentation helps: "GCC, Options for Linking"[^].

Quote:
what is the reason of using # in front of gcc.

The '#' character starts a comment line for the shell, hence

# gcc Sqlite_test.c -l sqlite3 -o tt

does nothing.

Solution 1

iirc the '-l' option says 'link against this (library)' or 'search this library for linkable references'
