[SOLVED] Compilation error. Header missing

[tonysonney]

Hi all,
I am compiling Android code on 2.6.28.2. I have my code something like follows.

#include<linux/input.h>
#include<linux/uinput.h>
#include<lsys/time.h>

void func (foo)
{
struct uinput_user_dev uinp;
............................
.............................
}

But i get error

error: linux/uinput.h: No such file or directory.
error:storage size of 'uinp' is'nt known

Does anybody know why I am getting the header missing error. I am confused, because it finds the header linux/input.h and misses linux/uinput.h which also is in the same folder. I checked in /usr/src/include/linux and have the header there.

Any pointers are appreciated.

Thanks,
Tony

Is it possible that the "file" linux/uinput.h is not a (missing) link? Also, it may be that where you are looking is not where the compiler is looking. Check the -L options in your make file.

Hello Rubberman,
Thanks for the quick reply. Yes you are right. I wrote a simple program and compiled it. It is finding both linux/uinput.h and linux/input.h. Actually the problem I mentioned is when I compile Android. I think it might take a long time to find where they have mentioned the -L option.
Thanks,
Tony

When you compile android, it is a kernel build and the headers the compiler uses are in a different spot than /usr/include. Make sure you read the documentation on building kernels (and android) and understand what you need to do to make sure your build environment is correct.

Also, I meant the -I option for include files, not -L for link libraries. Sorry, my bad...

Hi Rubberman,
You were right. I found it was looking in the folder

/bionic/libc/kernel/common/linux

for the header files and uinput.h was missing. I added the header uinput from the normal kernel and it is working.

Thanks,
Tony
