Hi Folks,
A quick question.
I have two kld modules, the second of which has an external linkage
dependence (a variable called mybla ) on the first. I have checked
that the symbol is exported in the one.ko module
nm one.ko | grep bla
0000000000012b30 D mybla
kldload one.ko
kldstat
Id Refs Address Size Name
1 2 0xe000000000500000 6d4e78 kernel
2 1 0xa000000004b34000 20000 one.ko
nm two.ko | grep bla
U mybla
but when I "kldload two.ko" I get
kldload: can't load two.ko: No such file or directory
and I a console message.
link_elf: symbol mybla undefined
I also tried to use the MODULE_DEPEND macro and to not
kldload one.ko. I can get the one.ko automatically loaded, I
then get the same console message, and one.ko gets automatically
unloaded.
If I take the one.o and two.o and create a three.ko I can kldload
quite happly and see both modules.
The question is "is this normal for FreeBSD 5.x" or is this an IA64
problem. I currently have no way of testing this on any another
FreeBSD 5.x
