node-20.x静态库vs2022下编译后的使用问题
Opened this issue · 4 comments
系统：win11
nodejs：20.x
编译命令：.\vcbuild.bat debug nonpm static openssl-no-asm vs2022 dll
问题描述：
静态库libnode编译成功，然后新建项目将test\embedding\embedtest.cc的代码复制到vs新建的其他项目运行结果报错：
错误信息：
c++新手求问，不胜感激

可以尝试找下看哪个文件有这些符号，看它编译到那个库。
不过最终搞不通也是常态，嵌入式方式不是nodejs的常规使用方式，我之前也是一个个版本的找到能使用的版本。而且还可能需要一些小修改满足各平台的编译。
