java - Why does Avahi "ant test-browse" fail with "libavahi4j.so: undefined symbol: avahi_malloc"? -

-

i able build avahi per instructions, next step in quick start of running "ant test-browse" results in symbol lookup error, , i'm confused how proceed troubleshooting problem. did find following post showed similar problem, wasn't able make progress (it seems thread never publicly resolved anyway). here error output see:

myuser@ubuntu:~/downloads/avahi4j-0.1$ ant test-browse buildfile: /home/myuser/downloads/avahi4j-0.1/build.xml  init:  compile:     [javac] /home/myuser/downloads/avahi4j-0.1/build.xml:109: warning: 'includeantruntime' not set, defaulting build.sysclasspath=last; set false repeatable builds  jar:  jnilib:      [exec] make: entering directory `/home/myuser/downloads/avahi4j-0.1/src'      [exec] make: nothing done `all'.      [exec] make: leaving directory `/home/myuser/downloads/avahi4j-0.1/src'  test-browse:      [java] avahi4j v0.1-0      [java] /usr/lib/jvm/java-7-oracle/jre/bin/java: symbol lookup error: /home/myuser/downloads/avahi4j-0.1/libavahi4j.so: undefined symbol: avahi_malloc  build failed /home/myuser/downloads/avahi4j-0.1/build.xml:185: java returned: 127  total time: 0 seconds

finally found workaround: export ld_preload=/usr/lib/x86_64-linux-gnu/libavahi-common.so:/usr/lib/x86_64-linux-gnu/libavahi-client.so

if can shed light on why manual hacking required, love suggestions on why standard build process did not work me (this on ubuntu).

i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
