<h1 id="loading-a-macos-native-librarys-dependencies">Loading a MacOS
Native Library's Dependencies</h1>
<p>Assume we have <code>libBindingtest1p1.dylib</code>, which links to
<code>libtest1.dylib</code>, i.e. requires the OS native library to load
<code>libtest1.dylib</code> to resolve symbols.</p>
<p>Usually we just se <code>DYLD_LIBRARY_PATH</code> including the path
where <code>libtest1.dylib</code> is located and we are good to go.</p>
<h2 id="just-use-dynamic-loading-via-gluegens-procaddresstable">Just use
dynamic loading via GlueGen's ProcAddressTable</h2>
<p>Note, the above problem does not occur when using GlueGen's
ProcAddressTable, i.e. loading the underlying tool library
<code>libtest2.dylib</code> w/ dlopen and passing all symbols to the JNI
library <code>libBindingtest1p2.dylib</code>.</p>
<h2 id="cant-pass-dyld_library_path-to-usrbinjava">Can't pass
<code>DYLD_LIBRARY_PATH</code> to <code>/usr/bin/java</code></h2>
<p>This is supposed to be related to MacOS's
<code>System Integrity Protect (SIP)</code>.</p>
<h2
id="workaround-inability-to-pass-dyld_library_path-to-usrbinjava">Workaround
inability to pass <code>DYLD_LIBRARY_PATH</code> to
<code>/usr/bin/java</code></h2>
<h3 id="use-explicit-openjdktemurin-jdk-java-executable-path">Use
explicit OpenJDK/Temurin JDK <code>java</code> executable path</h3>
<p>Interestingly passing <code>DYLD_LIBRARY_PATH</code> works using the
explicit <code>java</code> executable path, set by default as
follows:</p>
<pre><code># MacOS: Select JVM path to allow DYLD_LIBRARY_PATH
JAVA_HOME=`/usr/libexec/java_home -version 17`
PATH=$JAVA_HOME/bin:$PATH
export JAVA_HOME PATH</code></pre>
<h3 id="using-loader_path-within-dependent-library">Using
``@loader_path` within dependent library</h3>
<p>Set location of referenced library <code>libtest1.dylib</code> to
same path of dependent library <code>libBindingtest1p1.dylib</code>
using <code>@loader_path</code>.</p>
<pre><code>cd build-macosx/test/build/natives/
otool -L libBindingtest1p1.dylib
install_name_tool -change libtest1.dylib @loader_path/libtest1.dylib libBindingtest1p1.dylib
otool -L libBindingtest1p1.dylib </code></pre>
<p>Further we could try <code>@executable_path</code> and
<code>@rpath</code>.</p>
<p>See <a
href="https://www.joyfulbikeshedding.com/blog/2021-01-13-alternative-to-macos-dyld-library-path.html">An
alternative to macOS's DYLD_LIBRARY_PATH</a>.</p>
