In noticed that the epoll patch wants to patch source files in a directory called 'squid'), so make sure you mv SQUID-2.5STABLE12/ to squid/ after you extract from the tar.gz #> patch -p0 < epoll-2.5.patch To bootstrap, simply cd into squid/ and ./bootstrap.sh When I did it initially, bootstrap wasn't working for me, so I had to downgrade my automake and autoconf to the right versions, at least for STABLE12 which is what I was building at the time. Here are links for the versions that work: http://mirrors.kernel.org/gnu/autoconf/autoconf-2.13.tar.gz & http://mirrors.kernel.org/gnu/automake/automake-1.5.tar.gz -- you'll need to build and make them first before bootstrapping again. When you run bootsrap, you can ignore warnings but not errors! After you bootstrap without errors, you should be ready to run any preconfiguration commands you need and then configure. -----Original Message----- From: Michal Mihalik [mailto:michal.mihalik@xxxxxxxxxxxxx] Sent: Monday, March 27, 2006 2:05 PM To: 'Mike Solomon' Cc: squid-users@xxxxxxxxxxxxxxx Subject: RE: squid performance epoll. 350req/sec 100% cpu 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.
