Hello, this is very strange, because the tests from the configure script say, that the gethostbyname function is present on your system. I can only imagine that the compiled sipsak binary uses a wrong lib. To verify that please execute 'ldd sipsak'. Normaly the output should look like this: libc.so.6 => /lib/libc.so.6 (0x4002c000) /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000) The command 'grep gethostbyname /lib/libc.so.6' (use the lib from the ldd output above) should print the following: Binary file /lib/libc.so.6 matches If this does not match on your system, then you probably have a library problem on your system, which i'm probably not able to solve from remove.
