Hello, I had some trouble using hcid from bluez-utils 3.30 on my openwrt-router. Openwrt uses uClibc, not glibc. I discovered the following two problems: 1. In eglib/gmodule.c, function g_module_open, line 29 dlopen is used. The flags for dlopen come from hcid/plugin.c, function plugin_init, line 94. The flag-value is 0. According to the manpage of dlopen (http://www.kernel.org/pub/linux/docs/manpages/man-pages-2.79.tar.bz2), one of RTLD_LAZY or RTLD_NOW has to be set. uClibc checks this and returns an error. 2. hcid needs to be linked with -rdynamic or --export-dynamic. Some functions in the hcid-executable are used by the plugins. Without -rdynamic uClibc doesn't resolve the symbols in the plugins resulting in a NULL pointer dereference and a SIGSEGV. Again, its documented in the man-page of dlopen.
