+ The most convenient way to obtain the Privoxy source
+ code is to download the source tarball from our
+
+ project download page,
+ or you can get the up-to-the-minute, possibly unstable, development version from
+ https://www.privoxy.org/.
&buildsource;
+
+ Windows
+
+ Setup
+
+ Install the Cygwin utilities needed to build Privoxy.
+ If you have a 64 bit CPU (which most people do by now), get the
+ Cygwin setup-x86_64.exe program here
+ (the .sig file is here).
+
+
+ Run the setup program and from View / Category select:
+
+
+ Devel
+ autoconf 2.5
+ automake 1.15
+ binutils
+ cmake
+ gcc-core
+ gcc-g++
+ git
+ make
+ mingw64-i686-gcc-core
+ mingw64-i686-zlib
+ Editors
+ vim
+ Libs
+ libxslt: GNOME XSLT library (runtime)
+ Net
+ curl
+ openssh
+ Text
+ docbook-dssl
+ docbook-sgml31
+ docbook-utils
+ openjade
+ Utils
+ gnupg
+ Web
+ w3m
+
+
+
+ If you haven't already downloaded the Privoxy source code, get it now:
+
+
+ mkdir <root-dir>
+ cd <root-dir>
+ git clone https://www.privoxy.org/git/privoxy.git
+
+
+
+ Get the source code (.zip or .tar.gz) for tidy from
+
+ https://github.com/htacg/tidy-html5/releases,
+ unzip into <root-dir> and build the software:
+
+
+ cd <root-dir>
+ cd tidy-html5-x.y.z/build/cmake
+ cmake ../.. -DCMAKE_BUILD_TYPE=Release -DBUILD_SHARED_LIB:BOOL=OFF -DCMAKE_INSTALL_PREFIX=/usr/local
+ make && make install
+
+
+
+ If you want to be able to make a Windows release package, get the NSIS .zip file from
+
+
+ https://sourceforge.net/projects/nsis/files/NSIS%203/
+ and extract the NSIS directory to privoxy/windows.
+ Then edit the windows/GNUmakefile to set the location of the NSIS executable - eg:
+
+
+# Path to NSIS
+MAKENSIS = ./nsis/makensis.exe
+
+
+
+
+ Build
+
+
+ To build just the Privoxy executable and not the whole installation package, do:
+
+
+ cd <root-dir>/privoxy
+ ./windows/MYconfigure && make
+
+
+
+ Privoxy uses the GNU Autotools
+ for building software, so the process is:
+
+
+ $ autoheader # creates config.h.in
+ $ autoconf # uses config.h.in to create the configure shell script
+ $ ./configure [options] # creates GNUmakefile
+ $ make [options] # builds the program
+
+
+
+ The usual configure options for building a native Windows application under cygwin are
+
+
+
+ --host=i686-w64-mingw32
+ --enable-mingw32
+ --enable-zlib
+ --enable-static-linking
+ --disable-pthread
+ --disable-dynamic-pcre
+
+
+
+ You can set the CFLAGS and LDFLAGS envars before
+ running configure to set compiler and linker flags. For example:
+
+
+
+ $ export CFLAGS="-O2" # set gcc optimization level
+ $ export LDFLAGS="-Wl,--nxcompat" # Enable DEP
+ $ ./configure --host=i686-w64-mingw32 --enable-mingw32 --enable-zlib \
+ > --enable-static-linking --disable-pthread --disable-dynamic-pcre
+ $ make # build Privoxy
+
+
+
+ See the Developer's Manual
+ for building a Windows release package.
