The VideoLAN Forums

Good morning for all.

I'd just written a new module for VLC that search camera IPs in the network and write the damera's data into a database.
I'd tested it as stand alone and it works fine.

When I inserted it in the vlc machine, I'd received a message like below:

Should you tell me what is going on?
Thanks in advance.

missing sqlite3 so?

Your plugin is not linked correctly. It looks like you missed -lsqlite or something in the linker flags.

Here I show you my configure.ac, and I had put -lsqlite in the proper place(I think:-)

findip is my new module.

I put sqlite3.h in the file, and so on.
I cut the rest of the file because it is too large to be put here.

Isn't it OK?

Tanks.

look at what is inside vlc-config for your findip plugin
