Hello,

I decided to test gentoo-sources-3.4.0 and this is what happened.

Code:

drivers/scsi/advansys.c:71:2: attention : #warning this driver is still not properly converted to the DMA API


Warning are treated as errors so this stopped the compilation. I desactivated advansys from .config (I do not need this module, it was just there for no special reason) but if other people need I could find a patch. http://kerneltrap.org/mailarchive/linux-kernel/2008/5/21/1899454

Code:

  CC [M]  drivers/scsi/lpfc/lpfc_bsg.o
cc1: warnings being treated as errors
drivers/scsi/lpfc/lpfc_scsi.c: In function ‘lpfc_bg_setup_bpl’:
drivers/scsi/lpfc/lpfc_scsi.c:1900:11: error: unused variable ‘rc’


Again, -Werror problem. This thread http://comments.gmane.org/gmane.linux.kernel/1301034 says we can just remove -Werror from /usr/src/linux/drivers/scsi/lpfc/Makefile so I did it.

Code:

  CC      util-linux/volume_id/sysv.o
util-linux/mkfs_ext2.c:51:27: fatal error: linux/ext2_fs.h : No such file or folder


This is where I gave up for now.

If you have advices they are welcome
Thank you

ecko

How did you configure the kernel? When moving between some major release points (possibly like 3.3.x to 3.4.x) the kernel should be configured from scratch and not by using the previous config file with "make oldconfig".

I usually copy the file from the old major release to the new directory, then make menuconfig, do some dummy editing even if do not want to change anything, then exit and save. In the present case it was done several times since I wanted to remove some device drivers I do not need.

Now the picture changed, I think genkernel-3.4.24_p1 (stabilized yesterday, see bug #415483) is guilty.

I compile with
Code:
genkernel --no-clean --no-mrproper --makeopts=-j9 --oldconfig all


I can go into /usr/src/linux, type make && make modules, and it compiles. But if I run again the genkernel (3.4.24_p1) command, it fails the same way. I reverted to genkernel 3.4.20 and it works.
