preprocessing operation: gcc vs visual studios

[David Harel]

The code below works on VS but fails on gcc. Any idea?


#include <stdio.h>

#include <stdlib.h>
#include <string.h>

#define  STRINGIT(a)          #a
#define  FULL_PATH(d,f)    STRINGIT(d##/##f)

int main()
{
   char buf[1024];

   strcpy(buf, FULL_PATH(c:/root, config));
   printf("should be: c:/root/config. found: %s\n", buf);
}


Compilation and errors (on eclipse with CDT):

gcc -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"test.d" -MT"test.d"
-o"test.o" "../test.c"
./test.c:12:1: error: pasting "root" and "/" does not give a valid
preprocessing token
./test.c:12:1: error: pasting "/" and "config" does not give a valid
preprocessing token
