Hi im new to linux and openconnect, please help me how to install openconnect server in ubuntu 13.04 because each time i try toconfigure it i get error like : " configure: WARNING: *** *** autogen not found. We will not build manpages. *** checking size of unsigned long... 8 checking whether byte ordering is bigendian... no checking for LIBGNUTLS... no configure: error: Package requirements (gnutls >= 3.1.10) were not met: No package 'gnutls' found Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables LIBGNUTLS_CFLAGS and LIBGNUTLS_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. " i already have libgnutls and i cannot download gnutls because its not availabe in ubuntu repository. i download gnutls from their official site but its need libnettle 2.7 and i cant configure it because it gives me and error like : " decrypt-internal.s /bin/sh: 1: m4: not found make[1]: *** [aes-decrypt-internal.s] Error 127 make[1]: Leaving directory `/home/armin/Desktop/nettle-2.7' make: *** [all] Error 2 " i already have libnettle 4 installed pleaseeeeeeeeee help me how can i install openconnect server best regards Armin
