I want to include header files from /usr/src/linux/include because
I want to compile a module. I use the gcc -I option. It include header
files from the correct path but the header files alse include header
files , and those header files are included from /usr/include which is
my common include path. I don't know how to fix it , can anyone help
me ?
I dont think you are meant to use kernel header files directly so this
is the rule you are breaking here. But if you insist then the following
may help you.
Try using:
gcc -v -Iyourdir blah... blah...
To see where files are being included from and in what order.
Check out the options:
-nostdinc -nostdinc++
Then maybe reintroduce header files in the specific order you want.
Alternatively maybe the simplest trick is to add a symlink:
/usr/src/linux/kinclude -> include
To add -I/usr/src/linux
Then use:
#include <kinclude/linux/foobar.h>
#include <kinclude/asm/foobar.h>
You shove the verbatim linux kernel header files down the include file
hierarchy one level with a new unique subdirectory name "kinclude" which
doesn't clash with anything else.
