If you are willing to accept configure's default options, and build from within the source directory, you can simply type:</p> 114 115<pre><span class="crtprompt">$ </span><span class='crtin'>cd ImageMagick-7.0.10-62</span><span class='crtout'></span><span class="crtprompt">$ </span><span class='crtin'>./configure</span></pre> 116<p>Watch the configure script output to verify that it finds everything that 117 you think it should.

Shared libraries are preferred because they allow programs to share common code, making the individual programs much smaller. In addition shared libraries are required in order for PerlMagick to be dynamically loaded by an installed PERL (otherwise an additional PERL (PerlMagick) must be installed. 231 <br /><br /> 232 ImageMagick built with delegates (see MAGICK PLUG-INS below) can pose additional challenges. If ImageMagick is built using static libraries (the default without <code>--enable-shared</code>) 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>.a</code>, while shared libraries typically have extensions like <code>.so</code>, <code>.sa</code>, or <code>.dll</code>. 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. 233 <br /><br /> 234 PIC compilation flags differ from vendor to vendor (gcc's is <code>-fPIC</code>). However, you must compile all shared library source with the same flag (for gcc use <code>-fPIC</code> rather than <code>-fpic</code>). While static libraries are normally created using an archive tool like <code>ar</code>, shared libraries are built using special linker or compiler options (e.g. <code>-shared</code> for gcc). 235 <br/><br /> 236 If <code>--enable-shared</code> is not specified, a new PERL interpreter (PerlMagick) is built which is statically linked against the PerlMagick extension. This new interpreter is installed into the same directory as the ImageMagick utilities. If <code>--enable-shared</code> 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 <code>--enable-shared</code> if possible (note that all libraries used with ImageMagick must be shared libraries!).</td> 237 </tr> 238 <tr> 239 <td>--disable-static</td> 240 <td>static archive libraries (with extension <code>.a</code>) are not built. 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.e. libMagick.so); 3) building PIC versions of the delegate libraries may take additional expertise and effort; 4) you are unable to build shared libraries.</td> 241 </tr> 242 <tr> 243 <td>--disable-installed</td> 244 <td>disable building an installed ImageMagick (default enabled). 245 <br/><br /> 246 By default the ImageMagick build is configured to formally install into a directory tree.

For example, <code>--with-quantum-depth=8</code> builds ImageMagick using 8-bit quantums. Most computer display adapters use 8-bit quantums. Currently supported arguments are 8, 16, or 32. We recommend the default of 16 because some image formats support 16 bits-per-pixel. However, this option is important in determining the overall run-time performance of ImageMagick. 287 <br /><br /> 288 The number of bits in a quantum determines how many values it may contain. Each quantum level supports 256 times as many values as the previous level. The following table shows the range available for various quantum sizes. 289 <br /><br /> 290<pre class="highlight"><code>Quantum Depth Valid Range (Decimal) Valid Range (Hex) 291 8 0-255 00-FF 292 16 0-65535 0000-FFFF 293 32 0-4294967295 00000000-FFFFFFFF 294</code></pre> 295 <br /><br /> 296 Larger pixel quantums can cause ImageMagick to run more slowly and to require more memory. For example, using sixteen-bit pixel quantums can cause ImageMagick to run 15% to 50% slower (and take twice as much memory) than when it is built to support eight-bit pixel quantums. 297 <br /><br /> 298 The amount of virtual memory consumed by an image can be computed by the equation <var>(5 * Quantum Depth * Rows * Columns) / 8</var>. This an important consideration when resources are limited, particularly since processing an image may require several images to be in memory at one time.

If ImageMagick's installation prefix is not the same as PERL's PREFIX, then you may find that PerlMagick's <code>sudo make install</code> step tries to install into a directory tree that you don't have write permissions to. This common when PERL is delivered with the operating system or on Internet Service Provider (ISP) web servers. If you want PerlMagick to install elsewhere, then provide a PREFIX option to PERL's configuration step via "--with-perl-options=PREFIX=/some/place". Other options accepted by MakeMaker are 'LIB', 'LIBPERL_A', 'LINKTYPE', and 'OPTIMIZE'.

The configure script tests for headers and libraries by executing the compiler (CC) with the specified compilation flags (CFLAGS), pre-processor flags (CPPFLAGS), and linker flags (LDFLAGS). Any errors are logged to the file <code>config.log</code>. If configure fails to discover a header or library please review this log file to determine why, however, please be aware that *errors in the <code>config.log</code> are normal* because configure works by trying something and seeing if it fails. An error in <code>config.log</code> is only a problem if the test should have passed on your system.</p> 455 456<p>Common causes of configure failures are: 1) a delegate header is not in the header include path (CPPFLAGS -I option); 2) a delegate library is not in the linker search/run path (LDFLAGS -L/-R option); 3) a delegate library is missing a function (old version?); or 4) compilation environment is faulty.</p> 457<p>If all reasonable corrective actions have been tried and the problem appears be due to a flaw in the configure script, please send a bug report to the <a href="https://github.com/ImageMagick/ImageMagick/issues">ImageMagick Defect Support Forum</a>. All bug reports should contain the operating system type (as reported by <code>uname -a</code>) and the compiler/compiler-version. A copy of the configure script output and/or the relevant portion of <code>config.log</code> file may be valuable in order to find the problem. If you post portions of <code>config.log</code>, please also send a script of the configure output and a description of what you expected to see (and why) so the failure you are observing can be identified and resolved.</p> 458 459<p>ImageMagick is now configured and ready to build</p> 460 461<h2><a class="anchor" id="build"></a>Build</h2> 462 463<p>Once ImageMagick is configured, these standard build targets are available from the generated <code>make</code> files:</p> 464 465<dl class="row"> 466<dt class="col-md-4">make</dt> 467 <dd class="col-md-8">Build ImageMagick.</dd> 468<dt class="col-md-4">sudo make install</dt> 469 <dd class="col-md-8">Install ImageMagick.</dd> 470<dt class="col-md-4">make check</dt> 471 <dd class="col-md-8">Run tests using the installed ImageMagick (<code>sudo make install</code> must be done first).
