thank you for your reply however that is not my case. I installed openwrt on my soekris i486 box, openwrt use http://www.uclibc.org/ instead ob glib so this is a root cause.
I tried to install btsync on my openwrt (i486) box without success because openwrt is uclibc based. So it would be nice to have a uClibc build as well or at least static i386 build (I believe static build has been requested few times already). Thank you in advice
