Verify its message digest. ImageMagick RPM's are self-installing. Simply type the following command and you're ready to start using ImageMagick:. Note, if there are missing dependencies, install them from the EPEL repo. For other systems, create or choose a directory to install the package into and change to that directory, for example:. For example:.
If the bin subdirectory of the extracted package is not already in your executable search path, add it to your PATH environment variable. We recommend Homebrew which provides pre-built binaries for Mac some users prefer MacPorts. Download HomeBrew and type:.
The brew command downloads and installs ImageMagick with many of its delegate libraries e. Homebrew no longer allows configurable builds; if you need different compile options e. Create or choose a directory to install the package into and change to that directory, for example:.
You can download the iOS distribution directly from ImageMagick's repository. The first one includes headers and compiled libraries that have been used to compile ImageMagick. If PerlMagick fails to link with a message similar to libperl. Unpack the distribution it with this command: tar xvzf ImageMagick. Configure The configure script looks at your environment and decides what it can cobble together to get ImageMagick compiled and installed on your system.
For example, here is a recent report from our system: ImageMagick is configured as follows. Please verify that this configuration matches your expectations. These include, among others: CC Name of C compiler e. LIBS Extra libraries. Here are the optional features you can configure: --enable-shared build the shared libraries and support for loading coder and process modules.
Shared libraries are preferred because they allow programs to share common code, making the individual programs much smaller. If ImageMagick is built using static libraries the default without --enable-shared then delegate libraries may be built as either static libraries or shared libraries.
However, if ImageMagick is built using shared libraries, then all delegate libraries must also be built as shared libraries. Static libraries usually have the extension. Code in shared libraries normally must compiled using a special compiler option to produce Position Independent Code PIC. The only time this not necessary is if the platform compiles code as PIC by default. However, you must compile all shared library source with the same flag for gcc use -fPIC rather than -fpic.
While static libraries are normally created using an archive tool like ar , shared libraries are built using special linker or compiler options e. This new interpreter is installed into the same directory as the ImageMagick utilities. If --enable-shared is specified, the PerlMagick extension is built as a dynamically loadable object which is loaded into your current PERL interpreter at run-time. Use of dynamically-loaded extensions is preferable over statically linked extensions so use --enable-shared if possible note that all libraries used with ImageMagick must be shared libraries!
If you are building shared libraries, there is little value to building static libraries. Reasons to build static libraries include: 1 they can be easier to debug; 2 clients do not have external dependencies i.
By default the ImageMagick build is configured to formally install into a directory tree. This the most secure and reliable way to install ImageMagick. The uninstalled configuration is ideal for binary distributions which are expected to extract and run in any location. Certain ImageMagick algorithms, for example convolution, can achieve a significant speed-up with the assistance of the OpenMP API when running on modern dual and quad-core processors. Some applications which use the ImageMagick library may also require support for large files.
By disabling support for large files via --disable-largefile , dependent applications do not require special compilation options for large files in order to use the library. You can install ImageMagick from source. However, if you don't have a proper development environment or if you're anxious to get started, download a ready-to-run Linux or Windows executable. Before you download, you may want to review recent changes to the ImageMagick distribution. ImageMagick source and binary distributions are available from a variety of FTP and Web mirrors around the world.
These are the Linux variations that we support. If your system is not on the list, try installing from source. Although ImageMagick runs fine on a single core computer, it automagically runs in parallel on multi-core systems reducing run times considerably.
