| Viewing file: Select action/file-type: 2. Getting and Compiling Squid2.1 Which file do I download to get Squid?You must download a source archive file of the form squid-x.y.z-src.tar.gz (eg, squid-1.1.6-src.tar.gz) from the Squid home page, or. the Squid FTP site. Context diffs are available for upgrading to new versions. These can be applied with the patch program (available from the GNU FTP site). 2.2 How do I compile Squid?For Squid-1.0 and Squid-1.1 versions, you can just type make from the top-level directory after unpacking the source files. For example:
% tar xzf squid-1.1.21-src.tar.gz
% cd squid-1.1.21
% make
For Squid-2 you must run the configure script yourself before running make:
% tar xzf squid-2.0.RELEASE-src.tar.gz
% cd squid-2.0.RELEASE
% ./configure
% make
2.3 What kind of compiler do I need?To compile Squid, you will need an ANSI C compiler. Almost all modern Unix systems come with pre-installed compilers which work just fine. The old SunOS compilers do not have support for ANSI C, and the Sun compiler for Solaris is a product which must be purchased separately. If you are uncertain about your system's C compiler, The GNU C compiler is available at the GNU FTP site. In addition to gcc, you may also want or need to install the binutils package. 2.4 What else do I need to compile Squid?You will need Perl installed on your system. 2.5 Do you have pre-compiled binaries available?The developers do not have the resources to make pre-compiled binaries available. Instead, we invest effort into making the source code very portable. Some people have made binary packages available. Please see our Platforms Page. The SGI Freeware site has pre-compiled packages for SGI IRIX. Squid binaries for FreeBSD on Alpha and Intel. Squid binaries for NetBSD on everything Gurkan Sengun has some Sparc/Solaris packages available. 2.6 How do I apply a patch or a diff?You need the
cd squid-1.1.10
mkdir ../squid-1.1.11
find . -depth -print | cpio -pdv ../squid-1.1.11
cd ../squid-1.1.11
patch < /tmp/diff-1.1.10-1.1.11
After the patch has been applied, you must rebuild Squid from the
very beginning, i.e.:
make realclean
./configure
make
make install
Note, In later distributions (Squid 2), 'realclean' has been changed
to 'distclean'.
If patch keeps asking for a file name, try adding ``-p0'':
patch -p0 < filename
If your 2.7 configure optionsThe configure script can take numerous options. The most
useful is
% cd squid-x.y.z
% ./configure --prefix=/some/other/directory/squid
Type
% ./configure --help
to see all available options. You will need to specify some
of these options to enable or disable certain features.
Some options which are used often include:
--prefix=PREFIX install architecture-independent files in PREFIX

2.8 undefined reference to __inet_ntoaby Kevin Sartorelli and Andreas Doering. Probably you've recently installed bind 8.x. There is a mismatch between the header files and DNS library that Squid has found. There are a couple of things you can try. First, try adding If that doesn't seem to work, edit your arpa/inet.h file and comment out the following:
#define inet_addr __inet_addr
#define inet_aton __inet_aton
#define inet_lnaof __inet_lnaof
#define inet_makeaddr __inet_makeaddr
#define inet_neta __inet_neta
#define inet_netof __inet_netof
#define inet_network __inet_network
#define inet_net_ntop __inet_net_ntop
#define inet_net_pton __inet_net_pton
#define inet_ntoa __inet_ntoa
#define inet_pton __inet_pton
#define inet_ntop __inet_ntop
#define inet_nsap_addr __inet_nsap_addr
#define inet_nsap_ntoa __inet_nsap_ntoa
2.9 How can I get true DNS TTL info into Squid's IP cache?If you have source for BIND, you can modify it as indicated in the diff below. It causes the global variable _dns_ttl_ to be set with the TTL of the most recent lookup. Then, when you compile Squid, the configure script will look for the _dns_ttl_ symbol in libresolv.a. If found, dnsserver will return the TTL value for every lookup. This hack was contributed by Endre Balint Nagy.

2.10 My platform is BSD/OS or BSDI and I can't compile Squid

You may need to upgrade your gcc installation to a more recent version. Check your gcc version with
gcc -v
If it is earlier than 2.7.2, you might consider upgrading.
Alternatively, you can get pre-compiled Squid binaries for BSD/OS 2.1 at the BSD patches FTP site, patch U210-019. 2.11 Problems compiling libmiscutil.a on SolarisThe following error occurs on Solaris systems using gcc when the Solaris C compiler is not installed:
/usr/bin/rm -f libmiscutil.a
/usr/bin/false r libmiscutil.a rfc1123.o rfc1738.o util.o ...
make[1]: *** [libmiscutil.a] Error 255
make[1]: Leaving directory `/tmp/squid-1.1.11/lib'
make: *** [all] Error 1
Note on the second line the /usr/bin/false. This is supposed
to be a path to the ar program. If configure cannot find ar
on your system, then it substitues false.
To fix this you either need to:
2.12 I have problems compiling Squid on Platform Foo.Please check the page of platforms on which Squid is known to compile. Your problem might be listed there together with a solution. If it isn't listed there, mail us what you are trying, your Squid version, and the problems you encounter. 2.13 I see a lot warnings while compiling Squid.Warnings are usually not a big concern, and can be common with software designed to operate on multiple platforms. If you feel like fixing compile-time warnings, please do so and send us the patches. 2.14 Building Squid on OS/2by Doug Nazar In order in compile squid, you need to have a reasonable facsimile of a Unix system installed. This includes bash, make, sed, emx, various file utilities and a few more. I've setup a TVFS drive that matches a Unix file system but this probably isn't strictly necessary. I made a few modifications to the pristine EMX 0.9d install.
You will need to run scripts/convert.configure.to.os2 (in the Squid source distribution) to modify the configure script so that it can search for the various programs. Next, you need to set a few environment variables (see EMX docs for meaning):
export EMXOPT="-h256 -c"
export LDFLAGS="-Zexe -Zbin -s"
Now you are ready to configure squid:
./configure
Compile everything:
make
and finally, install:
make install
This will by default, install into /usr/local/squid. If you wish to install somewhere else, see the --prefix option for configure. Now, don't forget to set EMXOPT before running squid each time. I recommend using the -Y and -N options. Next Previous Contents |
