- The 'uts_name' stuff has changed in 2.6.19, which also
necessitates a minor mod to the Access Library code. The thing I
don't know how to handle correctly is that the new variable
'init_uts_ns' (in linux-2.6.x/init/version.c) is exported as
EXPORT_SYMBOL_GPL, which as I've learned, means that a non-GPL module
can't link to the symbol. So the ixp400.ko module has an 'unknown
symbol' error when it is loaded. This could be easily fixed, but not
correctly or (dare I say) legally. So what's the best way to solve
this problem?
I don't recall hitting this. What did you have to change in the
AccessLibrary code for this?
I've attached a diff of what I did for this. It still has the original
code, I just conditionally compiled in my slight change to get to it build.
Oh, Ok, I see. We changed ours to so that 2.6.19 and above it uses:
utsname()->sysname
utsname()->release
(Which are defined in linux-2.6.19/include/linux/utsname.h)
Regards
Greg
