Title: [MinGW] or and not interpreted as || and !
Post by: MoonKid on May 28, 2007, 02:46:11 pm

I am using Code::Blocks on WinXP with MinGW gcc.

I have a foreign project and try to compile it.
There is this piece of code

SEARCHPGM {         /* search program */
  SEARCHSET *msgno;      /* message numbers */
  SEARCHSET *uid;      /* unique identifiers */
  SEARCHOR *or;         /* or'ed in programs */
  SEARCHPGMLIST *not;      /* and'ed not program */
  SEARCHHEADER *header;      /* list of headers */
  STRINGLIST *bcc;      /* bcc recipients */

Look at '*or' and '*not'. I am not sure but I think the compiler interpret it as '*||' and '*!' what have to occure an error of course. This is the error:

Is it C++ standard to interpret or and not as the operators? If not, how can I turn that off?

The code works fine on MSVC.

AFAIK, "or" and "not" are compiled as operators, at least within gcc (edit: for g++, i.e. not in C but in C++). No idea on how to avoid it, but i think that the easiest way is "search and replace in files" and use another identifiers (initial capital or final underscore, for instance).

 :shock: Does it work fine or simply compiles without errors?

In any case, I think it's a bad idea to use such keywords for identifiers. Microsoft has a long historial of being too soft on programmers, and that leads to errors like this one.
