Description kevin martin 2012-01-24 16:21:14 UTC

Description of problem:attempting to compile the nvidia driver against the 3.3.0 kernel source finds missing include files.


Version-Release number of selected component (if applicable):kernel 3.3.0


How reproducible: always


Steps to Reproduce:
1.compile nvidia driver
2.compile fails

  
Actual results: nvidia driver won't compile due to missing kernel include files.


Expected results: nvidia driver compiles.


Additional info: kernel-devel-3.3.0 is missing (at least) the following include files:

/lib/modules/3.3.0-0.rc1.git0.3.fc17.x86_64/source/arch/x86/include/asm/unistd_32.h (needed by unistd.h)
/lib/modules/3.3.0-0.rc1.git0.3.fc17.x86_64/source/arch/x86/include/asm/unistd_64.h (needed by unistd.h)
/lib/modules/3.3.0-0.rc1.git0.3.fc17.x86_64/source/arch/x86/include/asm/unistd_32_ia32.h (needed by ia32_unistd.h)

Comment 1 Josh Boyer 2012-01-24 17:09:04 UTC

Those files are auto-generated by Kbuild now.  They are located in arch/x86/include/generated/ in the kernel-devel package.  The kernel build system adds -Iarch/x86/include/generated in the makefile invocation.

I'm not sure what problems the nvidia driver is having, but perhaps it needs to be adapted to the 3.3 kernel.

Comment 2 kevin martin 2012-01-24 17:18:43 UTC

Ah, I see.  the build needs to add the generated/asm directory to it's -I list.  Thanks.

Comment 3 kevin martin 2012-01-24 17:20:44 UTC

but how does ia32_unistd.h get the unistd_32_ia32.h file then?  It's asking for:


#define __SYSCALL_ia32_NR(x) (x)
#include <asm/unistd_32_ia32.h>


not the generated version.

Comment 4 kevin martin 2012-01-24 17:23:29 UTC

and unistd.h is not asking for the generated version either...it's looking for it in .....include/asm, not ....include/generated/asm.

You're aware of how the -I option works, correct?  It can be listed multiple times.  E.g.

-isystem /usr/lib/gcc/x86_64-redhat-linux/4.7.0/include -I/home/jwboyer/src/linux-2.6/arch/x86/include -Iarch/x86/include/generated -Iinclude  -include /home/jwboyer/src/linux-2.6/include/linux/kconfig.h -D__KERNEL__ 

which basically says "look for <asm/<whatever>.h> in the following directories in this order: /home/jwboyer/src/linux-2.6/arch/x86/include, arch/x86/include/generated/, include"

Comment 6 kevin martin 2012-01-24 18:50:57 UTC

Ah, my mistake, I had added a '-I/lib/modules/3.3.0-0.rc1.git0.3.fc17.x86_64/source/arch/x86/include/generated/asm' when all I needed was '-I/lib/modules/3.3.0-0.rc1.git0.3.fc17.x86_64/source/arch/x86/include/generated'.  Now it compiles.

Thanks.

Wonderful.  Closing this out.
