******************************************************************************* ** Building on Unix Platforms, Cygwin, and MinGW ******************************************************************************* ================== Build Requirements ================== -- autoconf 2.56 or later * If using MinGW, this can be obtained by installing the MSYS DTK -- automake 1.7 or later * If using MinGW, this can be obtained by installing the MSYS DTK -- libtool 1.4 or later * If using MinGW, this can be obtained by installing the MSYS DTK -- NASM * 0.98 or later is required for a 32-bit build * NASM 2.05 or later is required for a 64-bit build * NASM 2.07 or later is required for a 64-bit build on OS/X (10.6 "Snow Leopard" or later.) This can be obtained from MacPorts (http://www.macports.org/). The NASM 2.05 RPMs do not work on older Linux systems, such as Enterprise Linux 4. On such systems, you can easily build and install NASM 2.05 from the source RPM by executing the following as root: ARCH=`uname -m` wget http://www.nasm.us/pub/nasm/releasebuilds/2.05.01/nasm-2.05.01-1.src.rpm rpmbuild --rebuild nasm-2.05.01-1.src.rpm rpm -Uvh /usr/src/redhat/RPMS/$ARCH/nasm-2.05.01-1.$ARCH.rpm NOTE: NASM build will fail if texinfo is not installed. -- GCC v4.1 or later recommended for best performance ====================== Building libjpeg-turbo ====================== The following procedure will build libjpeg-turbo on Linux, 32-bit OS X, and Solaris/x86 systems (on Solaris, this generates a 32-bit library. See below for 64-bit build instructions.) cd libjpeg-turbo autoreconf -fiv sh ./configure make NOTE: Running autoreconf is only necessary if building libjpeg-turbo from the SVN repository. This will generate the following files under .libs/ libjpeg.a Static link library for libjpeg-turbo libjpeg.so.62.0.0 (Linux, Solaris) libjpeg.62.dylib (OS X) libjpeg-62.dll (MinGW) cygjpeg-62.dll (Cygwin) Shared library for libjpeg-turbo libjpeg.so (Linux, Solaris) libjpeg.dylib (OS X) libjpeg.dll.a (Cygwin, MinGW) Development stub for libjpeg-turbo shared library libturbojpeg.a Static link library for TurboJPEG/OSS libturbojpeg.so (Linux, Solaris) libturbojpeg.dylib (OS X) Shared library and development stub for TurboJPEG/OSS libturbojpeg.dll (MinGW) cygturbojpeg.dll (Cygwin) Shared library for TurboJPEG/OSS libturbojpeg.dll.a (Cygwin, MinGW) Development stub for TurboJPEG/OSS shared library ======================== Installing libjpeg-turbo ======================== If you intend to install these libraries and the associated header files, then replace 'make' in the instructions above with make install prefix={base dir} libdir={library directory} For example, make install prefix=/usr/local libdir=/usr/local/lib64 will install the header files in /usr/local/include and the library files in /usr/local/lib64. If 'prefix' and 'libdir' are not specified, then the default is to install the header files in /opt/libjpeg-turbo/include and the library files in /opt/libjpeg-turbo/lib. NOTE: You can specify a prefix of /usr and a libdir of, for instance, /usr/lib64 to overwrite the system's version of libjpeg. If you do this, however, then be sure to BACK UP YOUR SYSTEM'S INSTALLATION OF LIBJPEG before overwriting it. It is recommended that you instead install libjpeg-turbo into a non-system directory and manipulate the LD_LIBRARY_PATH or create sym links to force applications to use libjpeg-turbo instead of libjpeg. See README-turbo.txt for more information. ============= Build Recipes ============= 32-bit Library Build on 64-bit Linux ------------------------------------ Add --host i686-pc-linux-gnu CFLAGS='-O3 -m32' CXXFLAGS='-O3 -m32' to the configure command line. 64-bit Library Build on 64-bit OS/X ----------------------------------- Add --host x86_64-apple-darwin10.0.0 NASM=/opt/local/bin/nasm to the configure command line. NASM 2.07 from MacPorts must be installed. 32-bit Library Build on 64-bit OS/X ----------------------------------- Add CFLAGS='-O3 -m32' CXXFLAGS='-O3 -m32' LDFLAGS=-m32 to the configure command line. 32-bit Backward-Compatible Library Build on 64-bit OS/X ------------------------------------------------------- Add CFLAGS='-isysroot /Developer/SDKs/MacOSX10.4u.sdk \ -mmacosx-version-min=10.4 -O3 -m32' \ CXXFLAGS='-isysroot /Developer/SDKs/MacOSX10.4u.sdk \ -mmacosx-version-min=10.4 -O3 -m32' \ LDFLAGS='-isysroot /Developer/SDKs/MacOSX10.4u.sdk \ -mmacosx-version-min=10.4 -m32' to the configure command line. The OS X 10.4 SDK must be installed. 64-bit Library Build on 64-bit Solaris -------------------------------------- Add --host x86_64-pc-solaris CFLAGS='-O3 -m64' CXXFLAGS='-O3 -m64' LDFLAGS=-m64 to the configure command line. MinGW Build on Cygwin --------------------- Add --host mingw32 to the configure command line. This will produce libraries which do not depend on cygwin1.dll or other Cygwin DLL's. Sun Studio ---------- Add CC=cc CXX=CC to the configure command line. libjpeg-turbo will automatically be built with the maximum optimization level (-xO5) unless you override CFLAGS and CXXFLAGS. To build a 64-bit version of libjpeg-turbo using Sun Studio, add --host x86_64-pc-solaris CC=cc CXX=CC CFLAGS='-xO5 -m64' \ CXXFLAGS='-xO5 -m64' LDFLAGS=-m64 to the configure command line. ******************************************************************************* ** Building on Windows (Visual C++) ******************************************************************************* ================== Build Requirements ================== -- GNU Make v3.7 or later * Can be found in MSYS (http://www.mingw.org/download.shtml) or Cygwin (http://www.cygwin.com/) -- Windows SDK for Windows Server 2008 and .NET Framework 3.5 (or a later version) http://msdn.microsoft.com/en-us/windows/dd146047.aspx * The Windows SDK includes both 32-bit and 64-bit Visual C++ compilers and everything necessary to build libjpeg-turbo. If you do not already have Visual C++ installed, then this is the recommended solution. Also tested with Microsoft Visual C++ 2008 Express Edition (both are free downloads.) * Add the compiler and SDK binary directories (for instance, c:\Program Files\Microsoft Visual Studio 9.0\VC\BIN; c:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE; c:\Program Files\Microsoft SDKs\Windows\v6.1\bin) to the system or user PATH environment variable prior to building libjpeg-turbo. * Add the compiler and SDK include directories (for instance, c:\Program Files\Microsoft Visual Studio 9.0\VC\INCLUDE; c:\Program Files\Microsoft SDKs\Windows\v6.1\include) to the system or user INCLUDE environment variable prior to building libjpeg-turbo. * Add the compiler library directory (for instance, c:\Program Files\Microsoft Visual Studio 9.0\VC\LIB; c:\Program Files\Microsoft SDKs\Windows\v6.1\lib) to the system or user LIB environment variable prior to building libjpeg-turbo. -- NASM (http://www.nasm.us/) 0.98 or later ====================== Building libjpeg-turbo ====================== cd libjpeg-turbo make -f win/Makefile This will generate the following files under libjpeg-turbo\windows\: jpeg-static.lib Static link library for libjpeg-turbo jpeg62.dll Shared library for libjpeg-turbo jpeg.lib Development stub for libjpeg-turbo shared library turbojpeg-static.lib Static link library for TurboJPEG/OSS turbojpeg.dll Shared library for TurboJPEG/OSS turbojpeg.lib Development stub for TurboJPEG/OSS shared library #If a 64-bit Windows platform is detected, then the build system will attempt #to build a 64-bit version of libjpeg-turbo. You can override this by running # # make -f win/Makefile WIN64=no NOTE: For unknown reasons, Win64 support doesn't work yet, so at the moment, you have to run 'make -f win/Makefile WIN64=yes' to get a 64-bit build on 64-bit Windows. The paragraph above will apply once Win64 support is working. ******************************************************************************* ** Creating Release Packages ******************************************************************************* The following commands can be used to create various types of release packages: make rpm Create RedHat-style binary RPM package. Requires RPM v4 or later. make srpm This runs 'make dist' to create a pristine source tarball, then creates a RedHat-style source RPM package from the tarball. Requires RPM v4 or later. make deb Create Debian-style binary package. Requires dpkg. make dmg Create Macintosh package/disk image. This requires the PackageMaker application, which must be installed in /Developer/Applications/Utilities. make udmg On 64-bit OS X (10.6 "Snow Leopard" or later), this creates a version of the Macintosh package/disk image which contains universal i386/x86-64 binaries. The 32-bit fork of these binaries is backward compatible with OS X 10.4 and later, whereas the 64-bit fork is compatible with OS X 10.6 and later. OS X 10.4 compatibility SDK required. make nsi When using MinGW, this creates a Win32 installer for the GCC version of the libjpeg-turbo SDK. This requires the Nullsoft Install System (http://nsis.sourceforge.net/.) makensis.exe should be in your PATH. make -f win/Makefile dist This creates a Win32 installer for the Visual C++ version of the libjpeg-turbo SDK. This requires the Nullsoft Install System (http://nsis.sourceforge.net/.) makensis.exe should be in your PATH.
