I've tried to compile the 2.4.20-20.9 kernel and kernel modules time and again in a number of different ways, all to no avail. In my description, I apologize for the lack of details on the first few compilations....but here goes.

I decided to rebuild my kernel to include wireless lan support.

First, I compiled the preset kernel (a lot included that I don't have but it works so far) with CONFIG_NET_WIRELESS=y & CONFIG_NET_RADIO=y. I got a whole bunch of errors.

Then, figuring that I should refine the kernel config in the hope that it should match my version, I loaded a ready-made and changed only the processor type and disabled BlueTooth, ISDN, IrDA, and Ameteur Radio, all items that I don't have on my PC and never intend to use. The kernel compile errored out with numerous errors including dummy.o and kallsyms.

I then tried to compile the kernel with only the preset configuration, figuring that out of the box it would work. The kernel compiled fine but I got some module compilation errors.

Then I decided to compile it with everything enabled out of frustration and the kernel compilation failed.

Just now, I rebuilt the config from scratch with only what I have enabled and I got this at the end:

base.c: In function `is_devfsd_or_child':
base.c:1417: structure has no member named `p_opptr'
base.c:1417: structure has no member named `p_opptr'
base.c: In function `devfsd_ioctl':
base.c:3433: warning: unused variable `lock'
make[3]: *** [base.o] Error 1
make[3]: Leaving directory `/usr/src/linux-2.4.20-20.9/fs/devfs'
make[2]: *** [first_rule] Error 2
make[2]: Leaving directory `/usr/src/linux-2.4.20-20.9/fs/devfs'
make[1]: *** [_subdir_devfs] Error 2
make[1]: Leaving directory `/usr/src/linux-2.4.20-20.9/fs'
make: *** [_dir_fs] Error 2

I've seen the "first_rule" Error plenty of times.

Now, one of these times, I got the kernel and drivers to compile and install successfully, but it wouldn't boot:

kernel panic: can't mount root [ / ] file system

I've been attempting this for weeks and I just can't figure it out. I've compiled a FreeBSD kernel time and again without a hitch, so this is a little frustrating. Any analysis would be helpful, I can supply any info that's needed.

Pues, hasta

Hello

I am getting the same compile error when compile the 2.4.20.8 in the fs/devfs/base.c file (line #1417). Did you resolve this error, if so please let me know how to get rid of this compile error.

Thanks,

u have to patch your /usr/src/linux/fs/devfs/base.c
with above mentioned lines.

Bye.
