vdr crashes with vdr-rotor & gcc 4.1.1 [SOLVED]

txboy · 6. September 2006

After upgrading to gcc 4.1.1 & glibc 2.4 I can't start vdr with rotor plugin although it compiles ok.

This is the output I get from the error:

Hi,

there is a bug in the rotor plugin. The following patch should solve your problem:

Hi Thomas.

Thank you very much
That patch did the trick.

I was a little desperate because of the beginning of spanish football league, so I need this plugin working in order to find feeds

Thanks again

Thnx for the patch,

Had the same problem, installed gcc3.4, gcc4.0.1 nothing helped.

Now it is working fine.
