How to load library on linux dynamically?

[ktk]

Hello, everyone.

QLibrary mylib("./libtest");
if (mylib.isLoaded())
  // message 1
else 
  // message 2

QLibrary mylib("./libtest");
if (mylib.isLoaded())
  // message 1
else 
  // message 2

To copy to clipboard, switch view to plain text mode 

The result is that the library cannot be loaded, as the message 2 is always shown.

Any suggestion?

I'd try to add a line

mylib.load();

mylib.load();

To copy to clipboard, switch view to plain text mode

I think I've found the problem. I should put the libtest.so file under the /lib or /usr/lib, or use ldconfig instead.

Thanks all
