Mbed-cli: [ERROR] Attribute 'default_build' not found in target 'LPC1768'

[sillevl]

Hi, I am using Ubuntu Mate 16.04.
I installed mbed-cli using pip, and installed GCC ARM Embedded from https://launchpad.net/gcc-arm-embedded

I added the GCC_ARM_PATH to the global config with
`mbed config --global ARM_PATH "/usr/bin"

I then import the example program as documented in the readme:
mbed import https://mbed.org/teams/mbed/code/mbed_blinky/

Then I try to compile the project with the following command:
mbed compile -m LPC1768 -t GCC_ARM

I get the following error:

[ERROR] Attribute 'default_build' not found in target 'LPC1768'
[mbed] ERROR: "python" returned error code 1.
[mbed] ERROR: Command "python -u /home/sille/mbed_blinky/.temp/tools/make.py -t GCC_ARM -m LPC1768 --source . --build ./BUILD/LPC1768/GCC_ARM" in "/home/sille/mbed_blinky"

The error is shown on other targets as well.

Verbose output:

I can confirm this issue, this is due to revision mbed 2.0 9bcdf88f62b0 onwards. Works prior.

Regards,

Andrea

I would suggest

For now, open the mbed.bld file in text editor and replace everything with:

http://mbed.org/users/mbed_official/code/mbed/builds/25aea2a3f4e3
Then use 'mbed deploy' to update libraries to this revision.

[sillevl]

Thank You, I can confirm that this works.

Hi,
is there are different workaround available? Reason: I can only get BLE working with the latest mbed 2 release 129 for all NRF51 targets (online ide). It would compile with release 127, advertising is working, but I just can't get a successfull connection(Gatt Error). I tested BLE HRM & UartLoopback against NRF51_DK and HRM1017 targets in booth Online IDE and mbed-cli.

Cheers,
Jens

@screamerbg @theotherjimmy

This is still an issue and really needs to be addressed.

[theotherjimmy]

@jensstruemper Right now you can replace the line (280) of toolchains/gcc.py:

elif target.default_build == "standard":
    use_nano = False
elif target.default_build == "small":
    use_nano = True

with

elif getattr(target, "default_build", None) == "standard" or getattr(target, "default_lib", None) == "std":
    use_nano = False
elif getattr(target, "default_build", None) == "small" or getattr(target, "default_lib", None) == "small:
    use_nano = True

you get this error instead:

[ERROR] Feature 'LWIP' is not a supported features

which you can get rid of by removing lines 675-678 of tools/config.py . That should be this:

        for feature in features:
            if feature not in self.__allowed_features:
                raise ConfigException(
                    "Feature '%s' is not a supported features" % feature)

Then it works.

PLEASE NOTE: This is clearly a hack. I'm working on updating the mbed-sdk-tools repo to use the most recent released version of the tools from mbed-os.

[jensstruemper]

@theotherjimmy Thanks! Working fine. Happy to apply this until mbed-sdk-tools are updated.

I have the same issue with NUCLEO_L152RE based program. I'm using mbed-dev, so a mbed-dev.bld and not mbed.bld. The 25aea2a3f4e3 revision doesn't exist for this variant.
However, @theotherjimmy hack did the trick. Looking forward to some definitive fix :-)

[theotherjimmy]

@abouillot This issue will persist until https://developer.mbed.org/users/mbed_official/code/mbed-sdk-tools/pull-request/1 is merged, and you update your tools for your project. In the mean time, you could clone the branch mentioned in that PR as your tools, or use the workaround I mentioned above.

[theotherjimmy]

That PR has been mainlined. Please run mbed update. Please close this issue if it's resolved..

[sillevl]

Did a small test and I could not reproduce the problem with revision ad3be0349dc5. I will close this issue
