MongoDB.so: 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

Fetching http://www.cpan.org/authors/id/F/FR/FRIEDO/MongoDB-0.702.1.tar.gz ... OK
Configuring MongoDB-0.702.1 ... OK

cpanm报错了，使用--force参数文章源自运维生存时间-https://www.ttlsa.com/mongodb/mongodb-so-undefined-symbol-heutf8/

看起来一切完好。测试脚本

use MongoDB;
my $connection = MongoDB::Connection->new( host => 'localhost', port => 27017);

# 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：文章源自运维生存时间-https://www.ttlsa.com/mongodb/mongodb-so-undefined-symbol-heutf8/

# 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.文章源自运维生存时间-https://www.ttlsa.com/mongodb/mongodb-so-undefined-symbol-heutf8/
