Fix Net::zookeeper cannot find the dynamic link library symbol problem

Reference Net::zookeeper This package, may be reported this error

Can ' t load '/usr/local/lib64/perl5/auto/net/zookeeper/zookeeper.so ' for module Net::zookeeper:/usr/local/lib64/ perl5/auto/net/zookeeper/zookeeper.so:undefined symbol:zoo_perm_create at/usr/lib64/perl5/xsloader.pm Line 70. AT/USR/LOCAL/LIB64/PERL5/NET/ZOOKEEPER.PM Line 109.

View the 70 lines of XSLOADER.PM:

My $libref = dl_load_file ($file, 0) or do {require Carp; Carp::croak ("Can ' t load ' $file ' for Module $module: ". Dl_error ()); 73};

is actually loading zookeeper.so this dynamic link library. Let's objdump to see if this missing symbol is in this link library.

Marked as UND, which indicates that this is an external symbol and should be referenced by other libraries, is estimated to be the zookeeper library. But the Lib package has joined the Ld_library_path, very strange.

Try recompiling zookeeper.so (source under Zookeeper Contrib/zkperl), discover that the release package is organized with Makemaker, first generate makefile, and get the following hint:

[Email protected] zkperl]$ Perl makefile.pl Warning (Mostly harmless): No library found for-lzookeeper_mtgenerating a Un Ix-style makefilewriting Makefile for net::zookeeperwriting mymeta.yml and Mymeta.json

Note the first line of warning, which is the key to solving the problem. Most harmless,but harm this time. View the 31st line of makefile.pl

GetOptions (+ ' zookeeper-include=s ' + \ @zk_inc_paths, ' zookeeper-lib=s ' and ' = ' @zk_lib_paths 34);

Visible the second option is required.

Recompile.

[Email protected] zkperl]$ perl makefile.pl--zookeeper-lib=/home/zhangbin/env/libchecking If your kit is complete ... Looks goodgenerating a unix-style makefilewriting Makefile for net::zookeeperwriting mymeta.yml and Mymeta.json

Then make && sudo make install. Problem solving.

It may xsloader that there is no mechanism to automatically find available libraries and symbol tables from Ld_library_path.
