Hi all,
I'm trying to install and run libhbalinux. I had it working,
but it didn't seem to ever use libpciacess() or find any HBAs,
due to a failure of readlink on /sys/class/fc_host/hostX since
that's a directory and not a symlink.
I think the intent must have been to read /sys/class/fc_host/hostX/device.
I don't see how that ever worked, or any change that obviously
broke it. The kernel hasn't changed that from a link to a
directory recently, as far as I can tell.
So, I fixed that, but now I'm getting a failure to load
libpciaccess which results in the symbol pci_system_init()
not getting found.
Can anyone tell me what I might be doing wrong? I've
run ldconfig. I've linked libhbalinux against libpciaccess.
Here's the patch (cut/paste, not applicable):

Here's the error I get:
# ./fcoeadm -i
./fcoeadm: symbol lookup error: /usr/lib64/libhbalinux.so.2: undefined symbol:
pci_system_init
Thanks for any help you can give.
