    <p>I am getting unsatisfied link error when I'm trying to launch my C++ based app on Android. The problem only appear if I use any of STL mechanism, when I comment out all <code>std::vector</code> etc. the problem disappears.</p> <p>EDIT: I found out that this is about all C++, not only STL (ie. <code>new operator</code> also cause unsatisfied link error)</p> <p>I am using custom, standalone toolchain to build binary (targeting android 1.6), and link it with <code>libstdc++.a</code>, <code>libGLESv1_CM.a</code>, <code>liblog.a</code> and <code>libm.a</code>.</p> <p>In Java I call:</p> <pre><code>static { System.loadLibrary("GLESv1_CM"); System.loadLibrary("Game"); } </code></pre> <p>The exact build order is:</p> <pre><code>engine_sources -&gt; libengine.a game_sources + libengine.a + all mentioned libraries (using --whole-archive for each) -&gt; libGame.so Java_framework + libGame.so -&gt; Game.apk </code></pre> <p>Is there something I'm missing?</p> <p>Edit2: As suggested in <a href="http://mpigulski.blogspot.com/2010/09/debugging-dlopen-unsatisfiedlinkerror.html" rel="nofollow">http://mpigulski.blogspot.com/2010/09/debugging-dlopen-unsatisfiedlinkerror.html</a> I run <code>arm-linux-androideabi-ld.exe libGame.so</code> and got this:</p> <pre><code>arm-linux-androideabi-ld.exe: warning: cannot find entry symbol _start; defaulting to 00008270 libGame.so: undefined reference to `__aeabi_fadd' libGame.so: undefined reference to `__aeabi_fcmpgt' libGame.so: undefined reference to `__aeabi_i2f' libGame.so: undefined reference to `__aeabi_dmul' libGame.so: undefined reference to `__aeabi_d2f' libGame.so: undefined reference to `vtable for OpenGLRenderer' libGame.so: undefined reference to `__aeabi_fsub' libGame.so: undefined reference to `__aeabi_idiv' libGame.so: undefined reference to `__aeabi_fdiv' libGame.so: undefined reference to `__aeabi_uidiv' libGame.so: undefined reference to `__aeabi_fcmpeq' libGame.so: undefined reference to `__aeabi_fmul' libGame.so: undefined reference to `__aeabi_fcmplt' libGame.so: undefined reference to `__aeabi_f2d' </code></pre> <p>I am especially concerned about</p> <pre><code>libGame.so: undefined reference to `vtable for OpenGLRenderer' </code></pre> <p><code>OpenGLRenderer</code> is a child of abstract class which I am creating with <code>new</code>. Am I missing something here?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
