问题 I've made some access control program with PAM, and it can be compiled on Solaris 11 sparc and x86 now. I know that the architecture is difference between sparc and x86. Would I test on each platform? or just one platform case? thank you, read it. 回答1: It is hard to tell without knowing precisely what APIs and features your program is using but assuming it compiles well in both platforms and works fine in one of them, the risk for it to fail in the other is extremely low.
