在linux上为Windows编译,以便它输出可以在Windows上本机运行的Windows DLL文件(不需要cygwin或类似的东西)。基本上就像我在Windows框上运行编译一样,宁愿避免。
我已经尝试了很多方法,其中大多数似乎都可以成功编译,而使我留下* .la或* .so文件,而从没有* .dll。

我尝试使用dockcross,但是与本地执行时存在相同的问题,因此无法共享我为本地编译而调用的命令。正如您在下面看到的那样,我被告知要获取真正的本机DLL的唯一方法是安装了clang用于交叉编译,诸如mingw之类的东西将需要静态打包大多数库才能完全正常工作。

有人知道我在做什么错吗?我是交叉编译的新手。
