Compiling 2.5.32

Hi,

can anybody give me hint. I don't think it is a bug, but i don't know what this error means for me. It is in "make bzImage" and the config is attached. Symlink asm is on asm-i386 and i added "ln -s /usr/src/linux/include/asm-generic /usr/include/asm-generic". Build environment is Athlon, Kernel 2.4.18, gcc 2.95.3

From what I understand this happens when these conditions are met:
1. You use a recent version of binutils (Debian has one)
2. CONFIG_HOTPLUG is not set
3. You compile a driver that doesn't properly use __devexit_p macro

I fixed this in the IPS driver:

So, find and fix the driver, use hotplug, or get an older binutils.

Michael's problem is drivers/net/tulip/de2104x.c and this problem is known since several months.

There are two possible solutions:

1. make the driver hot-pluggable
2. #ifdef the .remove away

Jeff Garzik doesn't want 1. until "someone actually tells me they are trying to hot-plug such a card" and he didn't apply the following patch to #ifdef the .remove away if the driver is compiled statically into the kernel:

You only think this is a free country. Like the US the UK spends a lot of
time explaining its a free country because its a police state.

#if defined(MODULE) || defined(CONFIG_HOTPLUG)
#define __devexit_p(x) x
#else
#define __devexit_p(x) NULL
#endif

With the .config of Michael a __devexit_p in de2104x.c doesn't help because CONFIG_HOTPLUG is defined...
