[ECOS] build error in net directory

[ECOS] build error in net directory

[bgat]

Guys:


I just updated to the latest CVS and tried to build as follows:


ecosconfig new mbx
ecosconfig add net
ecosconfig add snmplib
ecosconfig add snmpagent
ecosconfig tree
make



Here's where I ended up:

[snip]

make[1]: Entering directory `/home/bgat/ecos/build-packages/net/tcpip/current'

make: *** [build] Error 2


I added -I<path-to-ecos>/packages/io/eth/current/include to the
include path in build-packages/net/tcpip/current/makefile, and I had
to do the same thing for
build-packages/net/snmp/agent/current/makefile.  I haven't run any
tests yet, but the build finishes, which I'll take to be a good
sign...  :^)


My main concern is that my setup is somehow broken, i.e. I haven't
used ecosconfig properly (I'm an ecos newbie).  If it's just a bug in
the build scripts, however, then here's a workaround.


Thanks!

Don't do it this way.  The 'net' package is not self sufficient.  What
you really want is:
  % ecosconfig new mbx net

The 'net' template adds both the basic network stack _and_ the ethernet
driver framework, which is where 'netdev.h' comes from.

Gary:


You know, I bet one of these days I'm going to need to RTFM.  :^)

Thanks for the help.  It also applies to snmp, I presume?

No, I don't think so.  I'm pretty sure that SNMP can be added, and be
sufficient, all by itself.

As for the manual, this point might have been hard to find there :-(
The problem is that the 'net' package, while mostly self contained in terms
of compilation, etc, needs additional packages such as the ethernet
driver framework to be complete.  It would be good [I'll look into this]
for the code which requires additional packages to make sure that they
are available and issue a more useful diagnostic when they are not.

In fact, the attached patch goes a long way towards this goal.

Indeed, so long as you have a working networked build, you can just add the
two (NB, two, snmplib and snmpagent) SNMP packages with "ecosconfig add ..."

I've always done it like this:

ecosconfig new rpsh2
ecosconfig add CYGPKG_NET CYGPKG_IO_ETH_DRIVERS CYGPKG_DEVS_ETH_ARM_KS32C5000

Is that method now depricated?

No, this is fine.  I was just pointing out that there is also the "net"
template which does part of this automatically.

No, just errorprone given a handy alternative :-). Another approach is to
do:

ecosconfig new mbx all
ecosconfig remove uitron libm

or whatever else you _don't_ want :).

RE: [ECOS] build error in net directory

[Doug Fraser]

Bill,

Congrats on getting things working.

It is still in too big a state of flux for my product
but I am tracking things anyway. I have a neat little board
here with an MPC850, 8MB flash, 16MB of SDRAM.
It is called QS850, I got it from SNMC < http://www.snmc.com >
My first real goal is to get QNX running on it.
In the background I am going to bring up RedBoot,
which may end up being my startup and IPL of choice.
