<h1 id="toc_0">Building Exiv2 dependencies with conan</h1>
<p>Conan is a portable package manager for C/C++ libraries. It can be used to create all dependencies needed to build Exiv2, without needing to install system packages.</p>
<p>This document provides a step-by-step guide to show you the basic usage of conan. For more details about the tool,
please visit the <a href="http://docs.conan.io/en/latest/">Conan documentation website</a>.</p>
<p>Although we provide step-by-step instructions to enable you to build Exiv2 with conan, we recommend that you read conan's documentation to understand the main concepts: <a href="http://docs.conan.io/en/latest/getting_started.html">Getting started with Conan</a></p>
<p>To build Exiv2 with conan, you will also need to install CMake. https://cmake.org/download/</p>

<h5 id="toc_13">Default Profile</h5>
<p>When you run conan install for the first time, it will detect and write the default profile ~/.conan/profile/default. On my Ubuntu system with GCC 4.9, this is:</p>
<div><pre><code class="language-bash">[settings]
os=Linux
os_build=Linux
arch=x86_64
arch_build=x86_64
compiler=gcc
compiler.version=4.9
compiler.libcxx=libstdc++
build_type=Release
[options]
[build_requires]
[env]</code></pre></div>
<h5 id="toc_14">Changing profile settings</h5>
<p>One of the most important <strong>profile</strong> settings to be adjusted in your conan profile when working on Linux is the field</p>
<div><pre><code class="language-bash">compiler.libcxx=libstdc++11 # Possible values: libstdc++, libstdc++11, libc++</code></pre></div>
<p>With the arrival of the c++11 standard, and the growing popularity of the <em>clang</em> compiler, it is increasingly important which version of the standard library to use (corresponds to the <code>-stdlib</code> compiler flag).</p>
<p>Recommended <strong>libcxx</strong>
settings works with conan and different compilers:</p>
<div><pre><code class="language-bash">compiler.libcxx=libstdc++11 # will use -stdlib=libstdc++ and define _GLIBCXX_USE_CXX11_ABI=1
compiler.libcxx=libstdc++ # will use -stdlib=libstdc++ and define _GLIBCXX_USE_CXX11_ABI=0
compiler.libcxx=libc++ # will use -stdlib=libc++
</code></pre></div>
<p>As a rule of thumb, set <code>compiler.libcxx=libstdc++11</code> when using a version of gcc >= 5.1.</p>
<p>More information about the standard library and GCC <a href="https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_dual_abi.html">dual ABI in gcc</a> with GCC works.</p>
<p>Please, be aware that normally when using gcc >= 5.1, _GLIBCXX_USE_CXX11_ABI is set to 1 by default. However some linux
distributions might set that definition to 0 by default. In case you get linking errors about standard c++ containers or
algorithms when bringing the Exiv2 dependencies with conan, this might indicate a mismatch between the value set in
<strong>compiler.libcxx</strong> and the default values used in your distribution.</p>

<h3 id="toc_15">2.2) Visual Studio Notes</h3>
<h3 id="toc_16">Profiles for Visual Studio</h3>
<p>You can build Exiv2 with either Visual Studio 2015 (version 14) or 2017 (version 15). You create profiles in %HOMEPATH%.conan\profiles with a text editor.</p>
<p>If you have an installation of Visual Studio 2017, the profile msvc2017Release64 is as follows:</p>
<div><pre><code class="language-ini">[build_requires]
[settings]
arch=x86_64
build_type=Release
compiler=Visual Studio
compiler.runtime=MD
compiler.version=15
os=Windows
arch_build=x86_64
os_build=Windows
[options]
[env]</code></pre></div>
<h3 id="toc_17">CMake Generators for Visual Studio</h3>
<p>In the step-by-step guide, the command <code>$ cmake ..</code> uses
the default CMake generator. Always use the generator for your version of Visual Studio. For example:</p>
<div><pre><code class="language-bash">c:\....\exiv2\build> conan install .. --profile msvc2017Release64 --build missing
c:\....\exiv2\build> cmake .. -G "Visual Studio 15 2017 Win64" -DCMAKE_BUILD_TYPE=Release
c:\....\exiv2\build> cmake --build . --config Release</code></pre></div>
<p>CMake provides 4 Generators. The 64 and 32 bit Generators have different names:</p>

<h3 id="toc_23">Changing profile settings with the conan command</h3>
<p>It is recommended that you create 8 profiles for msvc{2017|2015}{Release|Debug}{64|32}.</p>
<p>You can modify profile settings on the command line.
The following example demonstrates making substantial changes to profile settings by performing a 32 bit build using Visual Studio 2015 with a 2017 profile! This example is not considered good practice, it is an illustration to some conan flexibility which be useful when your build environment is automated.</p>
<div><pre><code class="language-bash">$ conan install .. --profile msvc2017Release64 -s arch_build=x86 -s arch=x86 -s compiler.version=14
$ cmake .. -G "Visual Studio 2015"
$ cmake --build . --config Release</code></pre></div>
<h3 id="toc_24">CMake/Cygwin Collisions on the build machine</h3>
<p>If you have Cygwin installed on your build machine, you may encounter the situation
that CMake erroneously finds library files in Cygwin directories and adds <code>c:\\cygwin64\\usr\\include</code> to the
compiler header search path. FindIntl is a prime suspect and I believe this issue is caused by %PATH%.</p>
<p>I recommend that you disable Natural Language Support when building with Visual Studio:</p>
<div><pre><code class="language-none">$ cmake .. -G "Visual Studio 15 2017 Win64" -DCMAKE_BUILD_TYPE=Release -DEXIV2_ENABLE_NLS=Off</code></pre></div>
<p>If necessary, temporarily rename c:\cygwin64\usr\include as c:\cygwin64\usr\uncle to hide those files when working with CMake.</p>

<h3 id="toc_25">2.3) Cygwin Notes</h3>
<p>Do not use conan on the Cygwin Platform. To build Exiv2 for Cygwin use CMake without conan. We recommend installing or building dependences (expat, zlib) with platform tools.</p>
<p><name id="2-4"></a></p>
<h3 id="toc_26">2.4) MinGW Notes</h3>
<p>Team Exiv2 supports MinGW msys/2. Team Exiv2 does not support MinGW msys/1.0.</p>
<p>As with Cygwin, we recommend installing or building dependencies with platform tools dependencies and using CMake to build Exiv2.</p>

<p>A <em><strong>recipe</strong></em> is a python file which indicates how to build a library from sources. The recipe
understands configurations: Platform/Compiler/Settings. If the remote server has a pre-compiled package for
your configuration, it will be downloaded. Otherwise, conan will compile the libraries on your machine using instructions in the recipe.</p>
<p>To illustrate, here is list of packages that returned by the command <code>$ conan search</code></p>
<div><pre><code class="language-bash">$ conan search --remote conan-center zlib/1.2.11@conan/stable</code></pre></div>
<p>The output should be:</p>
<div><pre><code class="language-bash">Existing packages for recipe zlib/1.2.11@conan/stable:

<p>Conan searches remote servers for a <em><strong>recipe</strong></em> to build the dependency. You can list them with the command:</p>
<div><pre><code class="language-bash">$ conan remote list</code></pre></div>
<p>You can add servers to the conan server search path:</p>

<p>Conan stores its configuration and local builds in the directory ~/.conan (%HOMEPATH%\.conan on Windows).</p>
<p>Conan installs several files and two directories:</p>
<div><pre><code class="language-bash">$HOME/.conan/profiles Configuration files for compilers/platforms

<p>The first time you run <code>$ conan install</code>, it will auto-detect your configuration and store a default profile in the file
$HOME/.conan/profiles/default</p>
<p>Normally you will want to define new profiles for choosing different compilers (msvc, gcc, clang), different
build_type (Release, Debug), runtimes (MD, MT, MDd, MTd)</p>
<p>The expected output should be something like this, in case it's the first time you run conan:</p>

<p>Note that it first downloads the recipes, and then the binary packages. When everything goes well, conan found
the recipes in the remotes, and it also found packages for our configuration (msvc2017, Release, MD).</p>
<p>However, if you use other configuration for which there are no packages in the remotes, you will get an error such as:</p>
<div><pre><code class="language-bash"> PROJECT: WARN: Can't find a 'zlib/1.2.11@conan/stable' package for the specified options and settings:

- Options: shared=False
ERROR: Missing prebuilt package for 'zlib/1.2.11@conan/stable'

Or read "http://docs.conan.io/en/latest/faq/troubleshooting.html#error-missing-prebuilt-package"</code></pre></div>
<p>In that case, we can tell conan to build the library:</p>
<div><pre><code class="language-bash">$ conan install .. --profile MyEsotericProfile --build missing</code></pre></div>

<code>$HOME/.conan/data</code>). When you execute the command <code>conan install</code> with the same profile, the following output is typical:</p>

<h2 id="toc_33">4 Building Exiv2 with Adobe XMPsdk 2016</h2>
<p>With Exiv2 v0.27, you can build Exiv2 with Adobe XMPsdk 2016 on Linux/GCC, Mac/clang and Visual Studio 2017.
Other platforms such as Cygwin are not supported by Adobe. Adobe/XMPsdk is built as a external library.
Applications which wish use the Adobe XMPsdk directly should build Exiv2 in this configuration and the
library can be used by the application and Exiv2. The Adobe XMPsdk can be built as a static or shared library (.DLL)</p>
<p>To build Exiv2 with Adobe XMPsdk 2016, should perform steps 1.1, 1.2 and 1.3 described above, then perform the following:</p>
<p><name id="4-1"></p>
<h5 id="toc_34">4.1) Add a remote directory to conan's recipe search path</h5>
<p>By default, conan knows about several public conan repositories. Exiv2 requires
the <strong>piponazo</strong> repository to find the XmpSdk dependency which is not available from <strong>conan-center</strong> repository.</p>
<div><pre><code class="language-bash">$ conan remote add conan-piponazo https://api.bintray.com/conan/piponazo/piponazo</code></pre></div>
