<div dir="ltr">Hi Jc,<div style>we've built a new shared library which calls our shared-tracker-library. It works perfectly outside of our plugin and the tracker can connect. As soon as we link the new shared library into the plugin, we have our connection problem again. It calls the function, produces all the output, but can't connect. So we can say that the<u> shared tracker library works for:</u></div>

<div dir="ltr">Hi Jc,<div>we can't really use a debugger, since we don't have the code for the shared library, only the header files. The methods of the shared library is definitely called, because we get an error message that a connection to the tracker can't be established. Can it be a problem, that the plugins are also shared libraries? We'll write a shared library that calls the tracker today, so we can see if the problem depends on calling the tracker-library from a shared library or if it is ctk specific.</div>
<div><br>Additional information: As far as we know, the tracker library was written in C (and not in C++)</div><div><br></div><div>Thanks for your help,</div><div>Florian</div><div><div class="h5"><div class="gmail_extra">

<p>Hi Florian,<br>
If it build without problem, did you try using a debugger to try to understand what s wrong?<br>

we are trying to link a shared library to connect to tracker from a plugin. We know, that the code that calls the .so library works in a test application and also in the main method of our CTK application. After we have added our code to the plugin and linked it to the .so library, we can link and compile the code without errors, but we don't get a connection to the tracker. </div>
