Bug 73088 – nvidia-kernel build fails because wrong ARCH gets passed to kernel

• Product: Gentoo Linux
• Status: RESOLVED TEST-REQUEST

[Description John Gluck 2004-12-01 16:11:49 UTC]

Bilding the nvidia-kernel used to work with the 3.3.4 version of gcc. So this seems to be a compiler related issue.

This applies tobith the nvidia-kernel-1.0.6111-r3 and the nvidia-kernel-1.0.6629

It looks for a file called:

/usr/src/linux-2.6.9-gentoo-r6/arch/x86/Makefile

But that doesn't exist because there is no "x86" architecture. I solved the problem by making a softlink as follows:

lrwxrwxrwx  1 root root 24 Dec  1 19:29 /usr/src/linux/arch/x86 -> /usr/src/linux/arch/i386

After which it builds and install the module properly.

Reproducible: Always
Steps to Reproduce:
1. emerge the package without the softlink as describe above.
2. build fails module is not installed (even though unless you look closely it seems like it installed)
3. unmerge the package
4. create the softlink as above.
5. emerge the package.
6. check the /lib/modules/blah-blah directory for the module. It's there
7. startx or whatever to test. It works. 

Actual Results:  
See above 

Expected Results:  
see above

Created attachment 45099 [details]
The attachment is the log for a failed build

[Comment 2 jack_mort 2004-12-01 23:52:22 UTC]

Same problem here on amd64...

[Comment 3 Donnie Berkholz (RETIRED) 2004-12-01 23:58:49 UTC]

Needs to use set_arch_to_kernel() and set_arch_to_portage() from eutils.eclass.

[Comment 4 Andrew Bevitt 2004-12-02 01:49:44 UTC]

Johnm : see the above comment, should this be done in the linux-info eclass?

[Comment 5 Andrew Bevitt 2004-12-02 01:50:37 UTC]

Actually for a point of reference, this doesnt happen here.

Which is very weird.

[Comment 6 John Mylchreest (RETIRED) 2004-12-04 13:39:05 UTC]

doesnt happen here either.
its actually caused simply by ARCH being set.
Will look at it shortly.

[Comment 7 Andrew Bevitt 2004-12-04 17:31:28 UTC]

The ebuilds used to unset ARCH before compiling...

That could just go back into them if necessary.

[Comment 8 John Mylchreest (RETIRED) 2004-12-10 15:08:13 UTC]

Could you please emerge sync, and then try again.
please re-open if you still have problems, and let me know how you get on with a comment.
cheers.

[Comment 9 John Gluck 2004-12-10 17:04:19 UTC]

I sucessfully emerged nvidia-kernel-1.0.6629 

on December 5th without having to make a softlink.

I guess the problem is fixed.

Excellent, glad its all working OK.

[Comment 11 jack_mort 2004-12-13 11:18:55 UTC]

Yep, I can confirm it also works for me.
