[omniORB] CORBA.h and std::min collision in VC++ 7.1

[Stefan Wegele]

Hello,

I have a problem using std::min and a corba object in the same file.
Here is the example:

#include <iostream>
#include <omniORB4/CORBA.h>
int main(int argc, _TCHAR* argv[])
{
long a=23, b=345;
long c = std::min(a, b);
std::cout << c << std::endl;
return 0;
}

I get:
error C2589: '(' : illegal token on right side of '::'
error C2059: syntax error : '::'
for the line with std::min.
If I remove the include of Corba.h then it works perfectly.

I declared: __WIN32__,__x86__,_WIN32_WINNT=0x0400, __NT__ and
__OSVERSION__=4
VC++ version: 7.1.6

Thanks, Stefan

What difference should that make?

I'd try including the correct header:

#include <algorithm>

Sounds like you have a macro definition of min somewhere in the headers
included by CORBA.h. Try
#undef min
bellow the
#include <omniORB4/CORBA.h>
line.

I think that this is a known problem on Win32. Take a look at this link:

Unfortunately Microsoft #define's macros min and max (yes, in lower
case). When working with that compiler in the past we have had to do

#undef min
#undef max

before using the those functions. Remember that macros do not respect
scope or namespaces. It really irks me when people don't put
MACRO_NAMES_IN_ALL_UPPER_CASE.
