[WLANware] FFF 1.4.1 can't load library 'libm.so.0' bei rrdtool

[Sven-Ola Tuecke]

Ahoi,

das ist ein *Stern* im Symlink? Ehrlich? Das 'n Ding - noch nie gesehen. Ist 
das ein stabiles Geraet? Oder rebootet es sporadisch?

Hallo Sven-Ola,


also der Symlink unter /lib ist Müll. Sag ich jetzt mal so.

lrwxrwxrwx    1 root     root            9 Oct 30 17:46 /lib/libm.so.0
-> libm-*.so

Nachdem ich diesen Symlink ersetzt hatte mit
rm /lib/libm.so.0
ln -s /lib/libm-0.9.27.so /lib/libm.so.0

ging es. Magst Du mal schauen, ich glaube es ist ein Bug.
Danke.
