Continuation character fails in compile stage
Last modified: 2005-10-31 17:00:50 EST
I try to compile the following, I get a parse erorr: #include <stdio.h> /* the continuation character causes an error. If the chaharacter is removed and the following two line are joined, there is no problem */ #define PRINT (x) \ printf(x); main(){ PRINT("\nHello\n"); } Note I have created a similar file in vi so there is no CR/LF issues and the problem still occurs. I have a lot of source code that relies on the continuation character support. Please confirm this a soon as possible. Thanks, Gene
Well, the code you provided above should give a parse error, because you have space between PRINTF and (, which causes that PRINTF is not a function like macro and the body of main expands to (x) printf(x);("\nHello\n"); If you indeed have no space between PRINTF and ( and the above is just a typo, then make sure there are no spaces/tabs after the \ at the end of line.
It turns out I was a little premature in my bug report. The file I was working with was transferred to my pc form a NT box. When I ran vi the extra characters did not show up. It did however when I ran vi in binary mode. Sorry for the inconveience.
