我正在寻找有关如何使用perl运行SIGAR API的任何信息或说明。我查看了放置Makefile.PL的绑定目录并创建了makefile，然后运行make命令，它运行良好但我无法运行任何示例。我还粘贴了运行“exmaples”目录中列出的示例程序时出现的错误。如果我错过任何东西，请告诉我。

尝试将libsigar-amd64-linux.so库放到Linux库加载器已知的位置，并明确告知ExtUtils :: MakeMaker路径：
…/sigar/bindings/perl$ perl Makefile.PL LIBS=-L/usr/lib64 INC=-I../../include

我已经在库路径中包含以下内容，这有助于。
export LD_LIBRARY_PATH = / u01 / test / hyperic-sigar-1.6.4 / bindings / perl /../../ sigar-bin / lib：/ usr / lib64
