问题描述
Error: Can't load '/home/oracle/.cpan/build/DBD-Pg-2.16.1/blib/arch/auto/DBD/Pg/Pg.so' for module DBD::Pg: libpq.so.5: cannot open shared object file: No such file or directory at /usr/lib/perl5/5.8.8/i386-linux-thread-multi/DynaLoader.pm line 230.
在安装DBD :: Pg perl模块时是否有人有类似的错误？我该怎么做才能解决它？
Did anyone have similar error while instaling DBD::Pg perl module ? what can I do to fix it ?
推荐答案
您应该使用perl来解决这些动态链接问题。使用 strace程序&>退出，然后对 libpq.so.5 使用grep。我的猜测是您的 libpq.so.5 放在错误的位置，或者您的配置错误。阅读 @dl_library_path 上的文档。
You should go under perl to solve these dynamic linking problems. Use strace program &> out, and then grep for libpq.so.5. My guess is your libpq.so.5 is in the wrong location, or your DynaLoader is misconfigured. Read the docs on @dl_library_path.
您可以看到您的搜索路径是什么（strace还会通过检查每个目录来显示它试图查找.so的路径）：
You can see what your search path is with this (the strace will also show it trying to find the .so by checking each directory):
perl -MDynaLoader -le'print for @DynaLoader::dl_library_path;'
确保您的 libpq.5.so 属于其中之一。 strace 还将显示内核是否正在向DynaLoader返回错误，表明该错误是伪装的。此外，它肯定会告诉您DynaLoader所知道的一切。
Make sure your libpq.5.so falls in one of those. The strace will also show if the kernel is returning an error to DynaLoader that it is cloaking; moreover, it will certainly tell you everything DynaLoader knows.
