Linux的32位应用程序移植到64位？应用程序、Linux
我即将端口超大规模的应用到64位， 我注意到，在网上有一些物品演出 这种移植了很多陷阱， 我想知道是否有一个可以协助移植到64位的任何工具，这意味着 在找到需要code的地方被改变....也许与warnnings海合会启用......是不是不够好？有什么好？
i'm about to port very large scale application to 64 Bits, i've noticed in that in the web there some articles which shows many pitfalls of this porting , i wondered if there is any tool which can assist in porting to 64 bit , meaning finding the places in code that needs to be changed.... maybe the gcc with warnnings enabled... is it good enough ? is there anything better ?
编辑：大家好我搜索如果有的话，可能是一个完整的编译器工具， 我知道GCC可以ASIST，但我怀疑它会找到所有未移植的问题， 将在运行时被发现....也许静态code分析工具，它强调 移植到64位？
Guys i am searching for a tool if any that might be a complete to the compiler, i know GCC can asist , but i doubt it will find all un portable problems that will be discovered in run-time....maybe static code analysis tool that emphasize porting to 64 bits ?
感谢
推荐答案
一个很好的工具，叫做的grep ;-) DO
A good tool is called grep ;-) do
grep -nH -e '\<int\>\|\<short\>\|\<long\>' *
和通过适当的替换这些基本整数类型的所有裸露的用途：
and replace all bare uses of these basic integer types by the proper one:
在数组的下标应为size_t
指针类型转换应该是 uintptr_t形式
在指针的差异应该是
prtdiff_t
类型与宽度N的假设
应 uintN_t
array indices should be size_t
pointer casts should be uintptr_t
pointer differences should be
prtdiff_t
types with an assumption of width N
should be uintN_t
等等，我可能忘记了一些。 然后的 GCC 上会告诉你所有的警告。你也可以使用铛为编译器它提供了更多的诊断。
and so on, I probably forgot some. Then gcc with all warnings on will tell you. You could also use clang as a compiler it gives even more diagnostics.
