Line concatenation in define

Line concatenation in define - 22/08/2005 14:56

I've included some headers now and i get a parser error everywhere where i've used line concatenation in a define.

It compiles fine with VC++ but not with gcc. I know that this looks like a newbie question, but i really don't understand why i get a parse error.

Code:

#define x \
10

#define xxxxx \
blah

warning: blah declared as function returning a function

Should work fine. Is there any whitespace after the backslash? If you're using a Unix gcc, that may include CR.

No, just the required whitespace in front of the backslash. But i am using Visual Studio under Windows to edit my files, maybe gcc doesn't like the newline?

Ok, i've checked some other code for the empeg in the hex editor and my code, my code has a 0x0D 0x0A as a newline while the other had just a 0x0A.

After i've removed the 0x0D the file compiles.

Seems like i have a problem now

Just get a dos2unix program. I know UltraEdit32 has it built in.

Windows uses \r\n for EOLs and Unix uses just \n. The fact that you're editing Unix text files with a Windows text editor is 100% the problem. You can fix them after the fact with the nearly ubiquitous dos2unix command.

Here is a plug in for the Visual Studio that allows to set the end of line: http://www.codeguru.com/Cpp/V-S/devstudio_macros/textoperations/article.php/c3161/
