Hello, I am trying to install squid-2.5.STABLE10 with wccpv2 support. I use STABLE9 with wccpv2 and I decided to upgrade to STABLE10. I used wccpv2.patch (don't remember where I got it, as it was a long time ago) with STABLE9 and it worked just fine. The same patch failed with STABLE10 (see patch.dump) and Makefile.in.rej is created (attached). I thought this patch is outdated and decided to look for up2date patch, so I found a patch located here:
http://devel.squid-cache.org/projects.html#visolve_wccpv2 I applied it without a problem but there is no --enable-wccpv2 in the output of ./configure --help. So here I am lost. I have found on forums that bootstrap.sh might help, but I get the following: [EMAIL PROTECTED]:/usr/local/src/squid-2.5.STABLE10# ./bootstrap.sh WARNING: Cannot find automake version 1.5 Trying automake (GNU automake) 1.4-p6 WARNING: Cannot find autoconf version 2.13 Trying autoconf (GNU Autoconf) 2.59 aclocal: configure.in: 27: macro `AM_PROG_CC_C_O' not found in library aclocal failed Autotool bootstrapping failed. You will need to investigate and correct before you can develop on this source tree [EMAIL PROTECTED]:/usr/local/src/squid-2.5.STABLE10# The system is Debian sarge updated to latest stable. Has anyone successfully pached STABLE 10 to support wccpv2? Thanks in advance. Best Regards, -- George Chelidze
