Bug 66558 – Failure to compile unmodified linux-2.6.9-rc3-mm2

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Greg Taylor 2004-10-06 12:27:56 UTC]

I emerged mm-sources (2.6.9-rc3-mm2), went on over to /usr/src/linux-2.6.9-rc3-mm2 and did a 'make menuconfig' and configured the kernel. I saved the config file, went to 'make && make modules_install' and I get the following error message:

arch/i386/kernel/irq.c:203: error: redefinition of 'is_irq_stack_ptr'
include/asm/hardirq.h:25: error: previous definition of 'is_irq_stack_ptr' was here
arch/i386/kernel/irq.c: In function `is_irq_stack_ptr':
arch/i386/kernel/irq.c:207: error: `hardirq_stack' undeclared (first use in this function)
arch/i386/kernel/irq.c:207: error: (Each undeclared identifier is reported only once
arch/i386/kernel/irq.c:207: error: for each function it appears in.)
arch/i386/kernel/irq.c:210: error: `softirq_stack' undeclared (first use in this function)
make[1]: *** [arch/i386/kernel/irq.o] Error 1
make: *** [arch/i386/kernel] Error 2



Reproducible: Always
Steps to Reproduce:
1. emerge mm-source
2. cd /usr/linux/linux-2.6.9-rc3-mm2
3. make menuconfig
4. make && make modules_install

Actual Results:  
The following error:

arch/i386/kernel/irq.c:203: error: redefinition of 'is_irq_stack_ptr'
include/asm/hardirq.h:25: error: previous definition of 'is_irq_stack_ptr' was here
arch/i386/kernel/irq.c: In function `is_irq_stack_ptr':
arch/i386/kernel/irq.c:207: error: `hardirq_stack' undeclared (first use in this
function)
arch/i386/kernel/irq.c:207: error: (Each undeclared identifier is reported only once
arch/i386/kernel/irq.c:207: error: for each function it appears in.)
arch/i386/kernel/irq.c:210: error: `softirq_stack' undeclared (first use in this
function)
make[1]: *** [arch/i386/kernel/irq.o] Error 1
make: *** [arch/i386/kernel] Error 2


Expected Results:  
Compiled the kernel :)

The kernel has not been modified at all and I'm running Gentoo on an Inspiron
5150, currently running linux-2.6.8-gentoo-r6.

Hum, and I can see that there is a fix to get reiser4 working with 4Kstacks
but reiser4 option still doesn't appear if CONFIG_4KSTACKS is enabled.

We don't support mm-sources, sorry.
