Hi ok I learned the strace and it does call select (99% of time) looks like my epoll is not active :-(( and I did found that I didn't compile it as I should. But now I am unable to compile because of this errors. I don't have automake 1.5 (only 1.4 1.6 1.7 1.9) And autoconf too I do have debian stable... And added to it apt sources -> testing (to get latest squid) Can someone help tu run this? I don't understand this whole think of automake autoconf # this one later doesn't compile cleanly # bootstrap.sh ########################################################3 WARNING: Cannot find automake version 1.5 Trying automake (GNU automake) 1.9.6 WARNING: Cannot find autoconf version 2.13 Trying autoconf (GNU Autoconf) 2.59 acinclude.m4:10: warning: underquoted definition of AC_CHECK_SIZEOF_SYSTYPE run info '(automake)Extending aclocal' or see http://sources.redhat.com/automake/automake.html#Extending-aclocal acinclude.m4:49: warning: underquoted definition of AC_CHECK_SYSTYPE configure.in:1555: warning: AC_CHECK_TYPE: assuming `u_short' is not a type autoconf/types.m4:234: AC_CHECK_TYPE is expanded from... configure.in:1555: the top level autoheader: WARNING: Using auxiliary files such as `acconfig.h', `config.h.bot' autoheader: WARNING: and `config.h.top', to define templates for `config.h.in' autoheader: WARNING: is deprecated and discouraged. autoheader: autoheader: WARNING: Using the third argument of `AC_DEFINE' and autoheader: WARNING: `AC_DEFINE_UNQUOTED' allows to define a template without autoheader: WARNING: `acconfig.h': autoheader: autoheader: WARNING: AC_DEFINE([NEED_FUNC_MAIN], 1, autoheader: [Define if a function `main' is needed.]) autoheader: autoheader: WARNING: More sophisticated templates can also be produced, see the autoheader: WARNING: documentation. configure.in:1555: warning: AC_CHECK_TYPE: assuming `u_short' is not a type autoconf/types.m4:234: AC_CHECK_TYPE is expanded from... configure.in:1555: the top level configure.in:1555: warning: AC_CHECK_TYPE: assuming `u_short' is not a type autoconf/types.m4:234: AC_CHECK_TYPE is expanded from... configure.in:1555: the top level configure.in:1555: warning: AC_CHECK_TYPE: assuming `u_short' is not a type autoconf/types.m4:234: AC_CHECK_TYPE is expanded from... configure.in:1555: the top level Autotool bootstrapping complete.
