copied!<p>I finally managed to figure this out! Here's how:</p> <p>In gdb, I printed all the shared libraries in memory with <code>info shared</code>. I copied this to a text file <code>shared.txt</code> and extracted the library names with:</p> <pre><code>cat shared.txt | grep -v \*|grep -v quit---|grep -v Syms\ Read|grep -v \(gdb\)|awk '{print $4}'>libs </code></pre> <p>From there, I checked the symbols in each library with:</p> <pre><code>for i in `cat libs|xargs`;do nm --demangle $i|grep checkPopulation; if [ $? -eq 0 ]; then echo \($i\); fi;done </code></pre> <p>Which prints all symbols containing "checkPopulation" followed by the name of the library that contains each. My output:</p> <pre><code>000adb18 T GlobalSearch::QueueManager::checkPopulation() 000adb8a T GlobalSearch::QueueManager::checkPopulation_() (/usr/lib/avogadro/1_1/contrib/randomdock.so) 000db682 T GlobalSearch::QueueManager::checkPopulation() (/usr/lib/avogadro/1_1/contrib/xtalopt.so) </code></pre> <p>So this "phantom" <code>checkPopulation_</code> symbol is coming from randomdock.so, which was built a long time ago against an older version of the static <code>libglobalsearch.a</code>, which contains the now removed <code>GlobalSearch::QueueManager::checkPopulation_()</code>. Removing randomdock.so causes everything to behave as it should.</p> <p>Thanks for all the suggestions -- I certainly learned a few new gdb tricks while tracking this down. There's also a lesson here about breaking API, too ;-)</p>
