我在将 Botan 编译为 Visual C++ 中的静态库方面非常不成功。build.h 文件包含以下代码:
#ifndef BOTAN_DLL
#define BOTAN_DLL __declspec(dllexport)
#endif
然后,这个宏在 Botan 代码库中几乎无处不在,如下所示:
class BOTAN_DLL AutoSeeded_RNG : public RandomNumberGenerator
我对上一个问题的理解是,您需要做的就是在没有值的情况下定义 BOTAN_DLL,它应该可以编译为静态库。但是,这样做会导致大量构建错误,例如“缺少标签名称”。有人知道怎么做吗?
编辑:这是将 /D "BOTAN_DLL" 添加到 makefile 导致的错误示例:
cl.exe /Ibuild\include /O2 /EHsc /GR /D_CONSOLE /D "BOTAN_DLL" /nologo
