c++ - Compile error due to syntax error in header file -


i have program relies on several include files. when define includes in order shown below program compiles fine.

#include <iostream> #include "opencv2/cvconfig.h" #include "opencv2/core/core.hpp" #include "opencv2/highgui/highgui.hpp" #include "opencv2/core/internal.hpp" // tbb wrappers #include "arrayfire.h"

however, when switch last 2 includes shown below

#include <iostream> #include "opencv2/cvconfig.h" #include "opencv2/core/core.hpp" #include "opencv2/highgui/highgui.hpp" #include "arrayfire.h" #include "opencv2/core/internal.hpp" // tbb wrappers

i compiler errors:

1>d:\libraries\tbb41\tbb41_20130613oss\include\tbb\task.h(765): error c2059: syntax error : '{' 1>d:\libraries\tbb41\tbb41_20130613oss\include\tbb\task.h(765): error c2334: unexpected token(s) preceding '{'; skipping apparent function body

this unexpected , i'd fix it. of includes libraries (opencv , arrayfire). suggestions on may cause , how fix issue?

edit here's relevant part of task.h:

759 #if __tbb_task_group_context 760    //! method deprecated , removed in future. 761    /** use method group() instead. **/ 762    task_group_context* context() {return prefix().context;} 763 764    //! pointer task group descriptor. 765    task_group_context* group () { return prefix().context; } 766 #endif /* __tbb_task_group_context */

in line 765, ide complains {, saying error: expected identifier

this caused following evil in 1 of arrayfire headers:

#define group(...)  __va_args__

this defines function-like macro replaced list of macro arguments; group(a,b) expands a,b, , (more importantly here) group() expands nothing. since macros have no respect language-level concepts scopes, interferes later declaration:

task_group_context* group () { return prefix().context; }

converting to

task_group_context* { return prefix().context; }

which not valid declaration.

the fix include "arrayfire.h" last, , careful names try use in own code; or #undef group (and other evil might perpetrate) after including it. or, if possible, kill fire , use less evil instead.
