Trying to use external lib for labjack u3 usb [message #18651]

Hello, I would like to write an app which can read a labjack u3 usb module (analog and digital io) on linux and I'm interested by ultimate++.

The driver for the u3 was correctly installed on the linux machine (I can run sample test program from labjack). I'm newbie on linux (I am experimented with C++builder on win32). The library (file.so) is installed in /usr/lib and there is a .h placed in /usr/include

How can I access the library functions in ultimate++ ? I made some search on this forum and found that I need to configure the package of my app to add the librarie but the link still failed. As I'm not shure of what to do, is there a sample of this kind ?

thanks in advance
regards from Belgium

Hello,

To use your functions :

#include <your-header.h>

(/usr/include is standard include path and compiler will use it automatically)

to link the library:

Project -> package organizer : right click -> add libraries

and in the edit at the right add your library name (without .so)

Hello cocob!
thanks for your message

in the package organizer, I added the library but I runs only if I write /usr/lib/liblabjackusb.so

In others samples, I don't see paths, if I put only the lib name, upp don't find it, is this normal ?

regards
