Summary0000408: Declaration of Makro ev in cenvir.h interferes with boost::system
DescriptionIn cenvir.h a Makro called "ev" in lower case is defined in line 67:

#define ev (*cSimulation::getActiveEnvir())

As boost uses a variable named "ev" in system_error.hpp, this leads to unwanted replacements and build breaks if you use boost libraries. I suggest to refactor it to a more meaningful name.

As a workaround you may change your include order, and include any boost using header first, but this is surely not wanted behavior.

"ev" cannot be renamed: that would cause extremely severe backward compatibility problems because all simulation models use it extensively.

Suggested workaround: undefine ev in your code before you include the boost headers. If you need to use ev in your code later, redefine with the original content (OMNeT++ version dependent).

#include <omnetpp.h>
#undef ev
