Hi all,<br>
<br>
I have compiled and installed rtl-sdr on CentOS 6 following
instructions.<br>
Everything compiles without errors, but:<br>
- when I run rtl_test I get the following errors:<br>

samples get lost. If you observe no further output, everything is
fine.<br>

If I run rtl_tcp I get the following errors when the client tries to

The same client connects without errors to another rtl_tcp instance
on a Windows 7 computer, with the same module.<br>
<br>
Any help is greatly appreciated.<br>
<br>
Thanks,<br>
