Hi,
I've been tasked with getting owfs to work on our embedded Linux platform
which runs an older 2.6.10 kernel. I just finished back porting the latest
w1 ds2482 and fuse kernel modules. My initial goal is to talk to a w1
ds2450
over i2c and eventually hang other w1 slaves off the ds2482 master.
Not that old. (2.4 also should work) -- but each version/platform may have
issues.
Now, I'm trying to build an owfs that is very lightweight for the embedded
environment. I've turned off most everything except i2c and owfs. (see
info
below)
Should be fine.
With my very reduced config, multithreading is also turned off. I get a
compile error in ow_presence.c:
ow_presence.c:172: error: structure has no member named 'devices'
ow_presence.c:177: error: structure has no member named 'device'
Fixed in the CVS -- thank you.
Checking the discussion, it looks like non-multithreading is not the typical
environment. It builds fine with MT enabled.
True, it is less commonly tested. Multithreading is useful with multiple
clients, or when autodiscovery is used. Also owftpd needs multithreading.
My first question is: is my lightweight config valid? For now, I just need a
way to get to the 2450 via i2c. Another question is can I build owfs to
run
without shared libraries?
You'll need libfuse. There is no reason why it can't be statically linked.
Any other suggestions on building a lightweight owfs is greatly appreciated.
Once it works, you can configure without debugging code.
Also strip the binaries.

Bob Bloom
