5. 项目结构

CsVeryLoveXieWenLi commented 1 week ago

当CGO_ENABLED=1， 进行编译时， 会将文件中引用libc的库（比如常用的net包），以动态链接的方式生成目标文件。 当CGO_ENABLED=0， 进行编译时， 则会把在目标文件中未定义的符号（外部函数）一起链接到可执行文件中。

不明所以，但是不启用则编译成功，或许是符号没定义就检测了。

buke commented 1 week ago

谢谢反馈 ，另外windows 编译可参考 https://github.com/buke/quickjs-go/issues/151#issuecomment-2134307728

CsVeryLoveXieWenLi commented 1 week ago

我又看了一会，确实是CGO的开关？ 如果不启用，使用了CGO的文件会被排除在外，导致缺定义，并非编译成功。

CsVeryLoveXieWenLi commented 1 week ago

谢谢反馈 ，另外windows 编译可参考 #151 (comment)

谢谢您的答复，另外问一下，怎么链接动态库呢？我编译了动态库，也生成了.a文件，相当于vc的.lib文件。 我也查看了符号导出，可是，不论我如何在CGO中编写链接信息，最终结果就是找不到导出的函数。

buke commented 1 week ago

原quickjs https://github.com/bellard/quickjs 并不支持编译为动态库，因此本项目是采取预编译为静态库，然后通过cgo调用。关于编译静态库的步骤请参考 https://github.com/buke/quickjs-go/blob/main/.github/workflows/build_static_lib.yml

好的，谢谢。

链接pthread后，则编译成功

CsVeryLoveXieWenLi commented 1 week ago

经过我的再次编译，如果使用了win32协议的线程模型，链接时会报错，如果使用posix协议的线程模型，则不会。

CsVeryLoveXieWenLi commented 1 week ago

有没有可能判断并链接？

CsVeryLoveXieWenLi commented 1 week ago

奇怪，我搜索了一下，又说win32没有多线程，posix有？不知道，目前来看，使用posix即可，这也是推荐使用的线程模型。
