在C++中,不同的架构意味着一些基本数据类型(int和long)和指针有不同的位宽。CMake 利用指针大小来收集目标机器的信息。通过CMAKE_SIZEOF_VOID_P变量可获得此信息,对于 64 位该值为8(因为指针是 8 字节宽)和对于 32 位该值为4(4 字节): 代码语言:javascript 代码运行次数:0 运行 复制 if(CMAKE_SIZEOF_V...

Q: Why no support for 64-bit word-size? A: All calculations are done in a temporary variable, which needs to be bigger than the word-size (to detect overflow etc.). So 64-bit word-size would need e.g. 128-bit temp-var. C99 only supports portable integers up to 64-bits. ...
Josée would like to thank Gabby Silberman, Karen Bennet, and the team at the Centre for Advanced Studies for their support while writing this book. And a big thank you goes to Stan for taking her 7 along on this great adventure. Finally, wed both like to thank the wonderful editorial ...
