[64studio-devel] Missing "asm-x86_64/tsc.h" file in kernel headers 2.6.19 i386

[Brad Powell]

Installed gcc-4.0 using the snapshot.debian.net repository.  Rebuilt the rt2570 module, which went fine, but trying to modprobe still faulted:

FATAL: Error inserting rt2570 (/lib/modules/2.6.17-2-multimedia-486/kernel/drivers/net/wireless/rt2570.ko): Unknown symbol in module, or unknown parameter (see dmesg)

dmesg shows:

rt2570: no version for "struct_module" found: kernel tainted.
rt2570: no version magic, tainting kernel.
rt2570: Unknown symbol there_is_no_init_MUTEX_LOCKED_for_RT_semaphores


Free, getting this working is not critical for me; rather, I'm forging ahead in the hope that this is helping make 64Studio a better product in the future (and hopefully helping others who are in similar spots with trying to build kernel modules).  If you're getting tired of me bugging you about this, just let me know.

Brad

Hi Brad,

  BP> You are correct in that it appears I compiled the module with gcc-4.1, as that is what /usr/bin/gcc points to.  However, I do not have gcc-4.0 installed on my system (a stock install of 64Studio 1.0.0 i386).  Furthermore, I cannot find gcc-4.0 available as a package to install from the 64Studio or Debian stable/testing/unstable repositories.  Am I missing something?

I've just checked, you're right, the 1.0.0 releases misses the gcc-4.0
packages,    with    which    kernel   2.6.17-2-multimedia-486     was
compiled. That's a bug!

As a workaround you can use this APT source line (put it in sources.list):

deb http://snapshot.debian.net/archive pool gcc-4.0

and then

apt-get install gcc-4.0

and it  should  do the  trick  (remember  to change  the  /usr/bin/gcc
symlink). Let us know, ciao!
