- 编译 .lib 或者 .dll
wolfssl 很好的提供了 win32 的工程=》sln 文件
这样就不用折腾 CMakeLists 文件了,使用 Visual Studio 打开 sln 文件后,设置好 Static 编译库即可,开箱即用
- 编译 .a 文件
如果需要编译 .a 库,可以借助 MINGW64 终端
因为 wolfssl 已经提供了 CMakeLists.txt,所以编译起来还是省事不少
在 MINGW64 终端中 cd 到 wolfssl/src,执行以下命令行:
cmake -S . -B build -G Ninja -DCMAKE_FLAGS="-DWOLFSSL_CRYPT_ONLY:BOOL=ON -DWOLFSSL_CRYPT_TESTS:BOOL=OFF -DWOLFSSL_DSA:BOOL=ON -DWOLFSSL_ECC:BOOL=OFF -DWOLFSSL_RSA:BOOL=OFF -DWOLFSSL_FILESYSTEM:BOOL=OFF -DWOLFSSL_ASYNC_THREADS:BOOL=OFF -DWOLFSSL_OLD_NAMES:BOOL=OFF -DBUILD_SHARED_LIBS:BOOL=OFF"
接着 ninja,可能会提示缺少 <stdint.h>
可以在源码中添加以下代码,
#if defined(__MINGW64__)
#include <stdint.h>
#endif
这样重新编译后就成功了
不过这样编译出的库名字有点奇葩,会编译出 libwolfssl.dll.a 的库
故可以采用 sh 脚本方法一步到位,也不会报缺少头文件的错误

另附鸿蒙库的编译脚本:
