Re: [Boost-users] \boost\cstdint.hpp(129) : error C2059: syntax error : '::'

2014-03-05 12:11 GMT+01:00 Uthpal Urubail :

I am trying use boost in my application. I am getting compiler error, if I try to include headers after one of the application include file where uint64_t is defined.

#if defined(OS_WIN) && !defined(uint64_t) #define uint64_t unsigned __int64 #endif

Error:

[...]

Can some one help me find the better solution to resolve these type of issues?

Hi Uthpal, Are you allowed to modify the application file? It is generally a bad idea to #define identifiers, that can likely be used in other header files. So, the preferred solution is to modify that application header. Instead of: #define uint64_t unsigned __int64 try: typedef unsigned __int64 uint64_t; Or better yet, just use #include or <cstdint> if they are available, because they provide the typedef uint64_t and alike. On the other hand, if you are not allowed to modify the offending application file, then you'll need some trickery to work around this. I can elaborate on this if you need it. HTH, Kris
