2 未解决的外部因素
我正在尝试编译 hello world php 扩展项目，但收到 2 个有关未解析外部的错误。我不确定如何解决这个问题，有人可以告诉我可能是什么问题吗？

I'm trying to compile a hello world php extension project and I'm getting 2 errors about unresolved externals. I'm not sure how to troubleshoot this, can someone tell me what might be the problem?

确定
estrndup()和zend_parse_parameters()位于哪个 *.lib 或 .o 文件中，并告诉链接器在链接阶段添加此类文件。Determine in which *.lib or .o file
estrndup()andzend_parse_parameters()are located and tell the linker to add such file(s) during the link phase.
