我试图在C中编译我的程序（使用cygwin）并且我一直在使用一个“冲突”的类型＆＃39;和一个隐含的声明＆＃39;当试图调用hide_game（）和show_game（）函数时。如果有人可以帮我解决这个问题，我会非常感激！

答案 0 :(得分：4)
您需要转发声明这两个函数，编译器在调用这些函数时不知道UILevel:
INSTALLUILEVEL_NONE 2 Completely silent installation.
INSTALLUILEVEL_BASIC 3 Simple progress and error handling.
INSTALLUILEVEL_REDUCED 4 Authored UI, wizard dialogs suppressed.
INSTALLUILEVEL_FULL 5 Authored UI with wizards, progress, errors.
或hide_game()。
在show_game()之前添加void hide_game();和show_game();将解决问题，通常这两个声明会添加到文件的顶部。
