Hi there,

I'm trying to install gentoo several times with genkernel but I allways get the same error after running genkernel all: "Error: Failed to compile the "modules" target..." and I have absolutely no clue what's going wrong during compilation :)

I'm working with an Athlon II x2 B28 processor (64 bit, 2 cores).

This is my make.conf:
Code:

CFLAGS="-02 -pipe"
CXXFLAGS="${CFLAGS}"
CHOST="x86_64-pc-linux-gnu"
USE="mmx sse sse2 -qt4 -kde gtk gnome dvd alsa"
MAKEOPTS="-j3"
GENTOO_MIRRORS="ftp://ftp.spline.inf.fu-berlin.de/mirrors/gentoo/"
SYNC="rsync://rsync11.de.gentoo.org/gentoo-portage"


As you see, I didn't dare to change to much in make.conf.
There are some compiler warnings in the middle of the genkernel.log:

Code:

  CC [M]  drivers/usb/core/usb.o
  CC [M]  drivers/scsi/lpfc/lpfc_scsi.o
cc1: warnings being treated as errors
drivers/scsi/lpfc/lpfc_scsi.c: In function 'lpfc_bg_setup_bpl':

  CC [M]  drivers/usb/host/ehci-hcd.o
  CC [M]  drivers/usb/core/hub.o
  CC [M]  drivers/usb/core/hcd.o


But the compiler keeps going on with compilíng until this point:

Code:

  LD [M]  drivers/usb/storage/ums-karma.o
  LD [M]  drivers/usb/storage/ums-sddr09.o
  LD [M]  drivers/usb/storage/ums-sddr55.o
  LD [M]  drivers/usb/storage/ums-usbat.o
make: *** [drivers] Error 2
* Gentoo Linux Genkernel; Version 3.4.24_p2

It would help me a lot to know at least, where I could get more information what exactly is breaking and how I could work around this.

Thanks for your Help :)

From your last error:

Code:
* Please consult /var/log/genkernel.log for more information


Have you looked at this log? It's likely that anyone who can help you will also need to see it.

Don't post the whole log here; do you know how to use wgetpaste to post a link to the log?

Somehow you have a -Werror plugged into your compile flow.
It looks like you have a regular warning there, an unused variable is a warning... but it turned into an error, and stopped the flow...

You could try also disabling this:
Code:
config SCSI_LPFC
        tristate "Emulex LightPulse Fibre Channel Support"
        depends on PCI && SCSI
        select SCSI_FC_ATTRS
        help
          This lpfc driver supports the Emulex LightPulse
          Family of Fibre Channel PCI host adapters.
to work around the issue, if you don't really need this fiber channel scsi adapter.

Hi eccerr0r,

thanks for the tip I'm about to trying this out. After sleeping a night over the problem I also thought about dropping the modules where the compiler fails.

@pidsley: The last two snippets are the parts of genkernel.log which in my opinion must point to the problem.

eccerr0r,
you were wright. The fibre channel modules were the problem. To remove them, I did the following:

  • in kernel-config I commented out CONFIG_SCSI_LPFC=m
  • in modules_load I deleted the modules lpfc and scsi_transport_fc from MODULES_SCSI

Thank you for your help!

And thank you all for this helpful forum, where I seldom need to do more than search for a keyword like 'genkernel' or 'lpfc' in order to solve anything Gentoo.

After reading this, I just invoked genkernel with

Code:
genkernel --xconfig all


and removed the pesky lpfc module. I didn't find any modules_load, but when I rebooted into the new kernel, the system came up just fine.

BTW, it appears like this problem in the 3.4 kernel has been known and fixed upstream since May, but with 3.4.9 hitting stable today, the bug has not gone away.

leifbk,
which switch did you use to shut it off? The switches for SCSI Fibre Channel support in menuconfig didn't change anything on my system. That was why I edited the config files by myself.

I just searched for the string 'lpfc'. You can do the same in menuconfig.

I had exactly the same problem and this solved it for me, too. Thanks!!

This fixed for me too. Very annoying bug as this happened on a fresh install, if i wasn't already a long time user of gentoo i would probably have given up if the "it works" kernel compile didn't work. (Yes i know i should be compiling my own kernel and i do, just later on systems i need up and working fast.)

Code:
generkernel all --menuconfig


then / to get the search box up and searched for lpfc and turned off the options below.

Code:
  │Symbol: SCSI_LPFC_DEBUG_FS [=n]                                         │

  │ Type  : tristate                                                        │
  │ Prompt: Emulex LightPulse Fibre Channel Support                         │
  │   Defined at drivers/scsi/Kconfig:1450       
  │
  │   Depends on: SCSI_LOWLEVEL [=y] && PCI [=y] && SCSI [=y]               │
  │   Location:                                                             │
  │     -> Device Drivers                                                   │
  │       -> SCSI device support                                            │
  │         -> SCSI low-level drivers (SCSI_LOWLEVEL [=y])                  │
  │   Selects: SCSI_FC_ATTRS [=m]


Let it run after saving the config and all was well in the world.

PostPosted: Fri Sep 07, 2012 1:54 pm    Post subject: graphics card Reply with quote

yeah, I did the same and the kernel finally compiled properly, but then I faced another problem, the graphic card is not recognized by the kernel, and it was before, and the driver it used is in the kernel though, so I don't know what to do, maybe I really needed the lpfc driver compiled. This is my graphics card:
Code:

00:02.0 VGA compatible controller: Intel Corporation 82G965 Integrated Graphics Controller (rev 02)
   Subsystem: Intel Corporation Device 514d

the LPFC is a specific SCSI driver, it shouldn't be needed for the VGA chipset graphics adapter, you should submit a new post for it. But you need to make sure that i915 DRM is enabled as well as kernel mode setting enabled by default.

I did what you said, I mean, I hadn't the kernel mode setting enabled by default, and it worked before, now with the 3.4.9 version I activated it and the video card is recognized again, but, another problem with the new kernel remains, I don't know whether it is related with the problem of this thread, this is my rc log, where you can see that my system clock freaks out, a terrible problem for a gentoo user..

Please make a new post with this issue, the clock problem is unrelated to the SCSI compile issue problem.

I've seen hardware clock issues in the past but never rootcaused it. Some of my machines have this issue, perhaps with a fresh post others can chime in on what they seen.

For what it's worth, and strangely eerie, one machine that I have clock problems on is also a i965 machine... (Foxconn motherboard). Go figure...
