mbed-net-sockets does not appear in github https://github.com/ARMmbed

What steps did I miss?

Hello Andy,
Did you set the target?
For example " yotta target frdm-k64f-gcc"

Thanks Stanley.

You’re right I didn’t set the target. I didn’t understand that this has to be done on every project, or it defaults to trying to build native on the build OS.

That got me a bit further, but I am can’t clear dependencies for mbed-client-examples. specifically mbed-example-network

error: sockets does not meet specification ~0.3.0 required by mbed-example-network
error: mbed-drivers does not meet specification ~0.6.3 required by mbed-example-network

Current sockets is 1.0.2 and mbed-drivers 0.11.1… mbed-example-network seems old.

I can build it, but the build fails with a couple of errors, if I hack the errors away (missing include file, and confusion if YOTTA_CFG_UVISOR_PRESENT is set or not, then I can build and run it. But he just says “Error occured” after a couple of seconds (Ethernet is plugged into network with a dhcp server).


(Andy Green) #4

Ah I read your other thread

They still have the wrong URL in the source…

With that I think it is working.

However I am not interested in the cloud part right now, just basic network function by itself.

So I will study the code.

Thanks for your help earlier ^^

Hello Andy,
I has tested mbed-example-network before, and it was built successfully.
Below is the commands procedure.

  1. git clone https://github.com/ARMmbed/mbed-example-network.git
  2. cd mbed-example-network
  3. yotta target frdm-k64f-gcc
    4.yotta build

I try to clone mbed-example-network again, and just built it 10 minutes ago, I also encounter build error, I check the module.json for many modules, and I found that many modules version are revised recently, so it cause the build errror.
I upload the previous tested version to git , you can try it.

Thanks Stanley.

I have managed to get the git client app to work by replacing uvisor-libs and mbed-example-network with git versions down yotta_modules instead of what was pulled in by yotta install, and update the JSON to want the ^1.0.0 versions that are in git.

The problems are mainly coming from nobody updated the registry with git pieces.

But there is a bug around YOTTA_CFG_UVISOR_PRESENT not being defined, in uvisor_libs. I can hack it to work and the application can build and run then. But it seems there should be a proper fix.


(Andy Green) #7

I pushed my changes to the new stuff to github (and sent pull requests).

The client app itself

And you need to git clone this down ./yotta_modules

before doing the yotta install

Then it should build and run OK – I only really tested it as far as DHCP. But without these fixes it won’t even build.


(Alessandro Angelino) #8

Hello @warmcat,
Thank you for reporting the issue with the YOTTA_CFG_UVISOR_PRESENT symbol. We fixed it and everything should be now back to normal. I also closed your PR as the fix needed to be done at the target level. Please check out my comment here and let me know if the problem persists.
