perl操作MongoDB报错undefined symbol: HeUTF8解决方法

因为shell操作mongo比较麻烦,只好尝试使用perl操作mongo,perl需要操作mongodb必须先安装相应的驱动,大部分人使用cpan安装,个人觉得太麻烦,使用cpanm安装perl模块。

# cpanm MongoDB
--> Working on MongoDB
Fetching http://www.cpan.org/authors/id/F/FR/FRIEDO/MongoDB-0.702.1.tar.gz ... OK
Configuring MongoDB-0.702.1 ... OK
Building and testing MongoDB-0.702.1 ... FAIL
! Installing MongoDB failed. See /root/.cpanm/work/1376540233.15152/build.log for details. Retry with --force to force install it.

cpanm报错了,使用–force参数

# cpanm MongoDB --force
--> Working on MongoDB
Fetching http://www.cpan.org/authors/id/F/FR/FRIEDO/MongoDB-0.702.1.tar.gz ... OK
Configuring MongoDB-0.702.1 ... OK
Building and testing MongoDB-0.702.1 ... FAIL
! Testing MongoDB-0.702.1 failed but installing it anyway.
Successfully installed MongoDB-0.702.1 (upgraded from 0.702.0)
1 distribution installe

看起来一切完好。测试脚本

脚本内容:

# cat /root/testMongo.pl
#!/usr/bin/perl
use MongoDB;
my $connection = MongoDB::Connection->new( host => 'localhost', port => 27017);

运行:

# perl /root/testMongo.pl
/usr/bin/perl: symbol lookup error: /usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi/auto/MongoDB/MongoDB.so: undefined symbol: HeUTF8

google查询“MongoDB.so: undefined symbol: HeUTF8”,只发现一篇相关文章.一群人讨论这个问题。其中一个人的解决方法如下:

# wget http://search.cpan.org/CPAN/authors/id/F/FR/FRIEDO/MongoDB-0.701.4.tar.gz
# tar -xzvf MongoDB-0.701.4.tar.gz
# cd MongoDB-0.701.4
添加如下内容到perl_mongo.h:
/* supply HeUTF8 if it's missing - ppport.h doesn't supply it, unfortunately */
 #ifndef HeUTF8
 #define HeUTF8(he) ((HeKLEN(he) == HEf_SVKEY) ?
 SvUTF8(HeKEY_sv(he)) :
 (U32)HeKUTF8(he))
 #endif
# perl Makefile.PL
# make
# make install

perl脚本运行ok.

实际上是因为不兼容的问题,对于系统RHEL5/CENTOS5发行版,mongodb的perl驱动最后的一个版本是v0.45

如下是国外网友的回复:

The latest version to compile, test and install properly on Rhel5/Centos5 is v0.45 by KRISTINA. (requires Any::Moose)
