How to Build Squid 3.5 for Windows on Cygwin¶

Note

We now have a new project - Web Filtering Proxy for Microsoft Windows. It combines best features of Web Safety but runs natively on Windows. No need to use Hyper-V or dive into Linux specifics. You can enable proxy authentication, HTTPS decryption and filtering with several mouse clicks from Microsoft Management Console. See https://webproxy.diladele.com/.

This post explains how to build latest Squid 3.5 for Microsoft Windows using Cygwin.

Install Cygwin (tested with 64 bit) including:
- gcc core
- gcc g++
- gcc tools epoch
- gcc make dep
- gdb (if you would like to debug squid in case of any problems)
- make
- automake (and automake last version)
- autoconf
- libtool
For some of the advanced external modules consider also installing:
- cppunit
- libcom_err-devel
- libcrypt-devel
- libdb-devel
- libexpat-devel
- libkrb5-devel
- libiconv-devel
- openldap-devel
- openssl-devel
- libsasl2-devel
- libxml2-devel
- perl-DBI
Download latest stable version of Squid from http://www.squid-cache.org/Versions/v3/3.5/, for example 3.5.11.tar.gz to the /usr/src
Unpack squid: tar -xvf squid-3.5.11.tar.gz
Download this patch and apply it inside the /usr/src/squid-3.5.11 (the patch allows increasing the number of file descriptors from 256 to 3200 on cygwin)
- patch -p1 < 3-5-11.patch

for configure we use this command (written as ONE line!)

./configure --bindir=/bin/squid --sbindir=/usr/sbin/squid --sysconfdir=/etc/squid
    --datadir=/usr/share/squid --libexecdir=/usr/lib/squid --disable-strict-error-checking
    --with-logdir=/var/log/squid --with-swapdir=/var/cache/squid
    --with-pidfile=/var/run/squid.pid --enable-ssl --enable-delay-pools
    --enable-ssl-crtd --enable-icap-client --enable-esi --disable-eui
    --localstatedir=/var/run/squid --sharedstatedir=/var/run/squid
    --datarootdir=/usr/share/squid --enable-disk-io="AIO,Blocking,DiskThreads,IpcIo,Mmapped"
    --enable-auth-basic="DB,LDAP,NCSA,POP3,RADIUS,SASL,SMB,fake,getpwnam"
    --enable-auth-ntlm='fake' --enable-auth-negotiate='kerberos,wrapper'
    --enable-external-acl-helpers='LDAP_group,SQL_session,eDirectory_userip,file_userip,kerberos_ldap_group,session,time_quota,unix_group,wbinfo_group'
    --with-openssl --with-filedescriptors=65536
    --enable-removal-policies="lru,heap"

make
make install

Wait until Squid is built and watch out for possible errors!
