我们最常用的 DBD::mysql 模块，我发现是难住很多人的地方。因为安装老是失败，下面我介绍一下解决方法，比如我使用 cpanm 安装，有时就出 /home/nue2501j/work/DBD-mysql-4.010/blib/arch/auto/DBD/mysql/mysql.so: undefined symbol: DBIc_TRACE_LEVEL at /usr/lib/perl5/5.8.5/i386-linux-thread-multi/DynaLoader.pm line 230.
如下
cpanm DBD::mysql出错
# Tried to use 'DBD::mysql'.
# Error: Can't load '/home/nue2501j/work/DBD-mysql-4.010/blib/arch/auto/DBD/mysql/mysql.so' for module DBD::mysql: /home/nue2501j/work/DBD-mysql-4.010/blib/arch/auto/DBD/mysql/mysql.so: undefined symbol: DBIc_TRACE_LEVEL at /usr/lib/perl5/5.8.5/i386-linux-thread-multi/DynaLoader.pm line 230.

$ sudo perl -MCPAN -e shell
cpan> install Bundle::DBD::mysql
/usr/bin/make -- OK
/usr/bin/make test -- OK
/usr/bin/make install -- OK
cpan> install DBD::mysql
DBD::mysql is up to date.
