[U-Boot-Users] How can a file in directory "u-boot-1.1.4\include\configs" be included?

[陈敏]

Hello guys

I'm a beginner at u-boot porting and have a question about how can a file in directory "u-boot-1.1.4\include\configs", say pxa255_idp.h, be included in the whole project? I just can not find any code line like "#include <pxa255_idp.h>". The question is easy for non-beginners but hard for me. Any advice is appreciated.

Those files are being included through the make file. See the Makefile under
appropriate configuration section.

Thanks & Regards,

There is no such file.  Both  '\i'  and  '\c'  are  undefined  escape
sequences in the C programming language.

You just include <config.h> - this takes care of all you need.

Best regards,

Hi Wolfgang,

The context here could be either cpp or shell.  Backslash \ is a valid 
escape in all shells that are worthy of being used at denx.de (I forgot 
if you prefer bash or csh).  Either way, your statement is still 
correct, there is no file "u-boot-1.1.4includeconfigs" (or 
"u-boot-1.1.4includeconfigspxa255_idp.h" to extrapolate the question).

$ ls -l u-boot-1.1.4\include\configs\pxa255_idp.h
/bin/ls: u-boot-1.1.4includeconfigspxa255_idp.h: No such file or directory

$ touch u-boot-1.1.4\include\configs\pxa255_idp.h

$ ls u-boot-1.1.4\include\configs\pxa255_idp.h
u-boot-1.1.4includeconfigspxa255_idp.h

$ cat x.c
/*
  * Test escaping in the C compiler
  */
#include "u-boot-1.1.4\include\configs\pxa255_idp.h"

int main(int argc, char *argv[])
{
         return(0);
}

$ make x
cc     x.c   -o x
x.c:4:53: u-boot-1.1.4\include\configs\pxa255_idp.h: No such file or 
directory
make: *** [x] Error 1
