You are right, the bits/fcntl-32.h at the very end has a
#include <bits/fcntl-linux.h>
But, all lines in <bits/fcntl.h> are greyed (not active), except these I noted as bold (below). So it not become active.
I would assume __arm__ should be set by someone.
It seems it is not a problem for the compiler, but for the Eclipse viewer to show the code.
That is the problem here. I try to set ARCH=arm at various places in eclipse. but id doesn't have an effect.
Mhh.

Have you looked at the content of bits/fcntl-32.h?

Betreff: Re: [yocto] O_RDONLY ... missed bits/fcntl.h not as expectedCan you explain what the actual problem is?For me the include you'd use in programs <fcntl.h> includes <bits/fcntl.h> which includes <bits/fcntl-linux.h> which defines O_RDONLY.RossOn 12 March 2018 at 07:32, Arno Steffens <s...@gmx.li> wrote:I looked for
#define O_RDONLY 00
#define O_WRONLY 01
#define O_RDWR 02
and found it in : bits/fcntl-linux.h. According to this file it should not be included, but bits/fcntl.h.
And it requires something like that:
A minimal <bits/fcntl.h> contains just:
struct flock {...}
#ifdef __USE_LARGEFILE64
struct flock64 {...}
#endif
#include <bits/fcntl-linux.h>
But this doesn't finally include the fcntl-linux.h as expected. Am I doing something wrong?
Regards
Arno
