mbed-os working on mbed-CLI, but not mbed-classic

I've spent a while on this and read around without luck so hope someone can help.

I've downloaded and setup my mbed-cli as per: https://www.youtube.com/watch?v=cM0dFoTuU14 (minor deviation is I have installed 2016q3 first and 2016q2 second (2016q2 without 'Add path to environment variable' or 'Add registry information').

I've successfully imported and compiled mbed-os-example-blinky as per this great blog post: http://grbd.github.io/posts/2016/11/06/using-the-mbed-cli/

I'm trying to work with mbed classic projects and no success. I always get he same Linker issue. I have created my own projects using mbed-CLI (<<code>>new mbed-classic-program --mbedlib<</code>>), exported code and tried mbed_blinky from: https://developer.mbed.org/users/mbed_demo/code/mbed_blinky as per: https://www.youtube.com/watch?v=PI1Kq9RSN_Y

In all cases I get many issues around the Linker including <<code>>undefined reference to `__wrap_exit'<</code>>

I have tried this with 2016q3 and 2016q2 (by using: mbed config GCC_ARM_PATH "C:\Program Files (x86)\GNU Tools ARM Embedded\5.4 2016q2\bin"). Any ideas what is wrong? Below is a full cmd session showing the issue. The mbed build looks to be the same as in the youtube video (Unpacking library build "f9eeca106725" in "C:\SOURCE\retry\mbed_blinky\mbed").

Is anyone successfully working with mbed-classic under mbed-CLI?

Hey Chris,

This was a bug in mbed-sdk-tools. The bug was that the tools would not recognize the mbed 2 revisions after a particular number, and treat them as mbed-os. I have updated these tools to include the most recent versions of mbed 2 libraries. You should be able to replace the tools with the new version and have no problems

TL;DR: delete the ".temp" directory and "mbed deploy" and try again. It should work this time

The problem seems to be NOT solved. Compilation success with mbed-os-example-blinky, but fails with mbed_blinky! I tried with gcc-arm-none-eabi-5_4-2016q2 and gcc-arm-none-eabi-5_4-2016q3.

First, we use gcc_arm_embedded 4.9.3, but that's not related to your problem. As I cannot reproduce this error on my machine, I would like to know a bit more information.

The procedure I followed is (Linux, GCC ARM Embedde v 4.9.3):

1. `$ mbed import http://mbed.org/teams/mbed/code/mbed_blinky/`

2. `$ cd mbed_blinky`

3.`$ mbed compile -t gcc_arm -m k64f`

How does this compare to your process? Which OS are you running this on?

posted by the other jimmy 24 Feb 2017

I run the whole procedure again, and the problem has apparently disappeared!

My OS is Debian Jessy.

1 - '$ mbed import http://mbed.org/teams/mbed/code/mbed_blinky/'

2 - '$ cd mbed_blinky/'

I noticed that the library build downloaded is the ad3be0349dc5, which it is different from the previous one that I used The problem is now import project to Simplicity Studio V3 (import->Simplicity Studio -> MCU Project) after the command

- 7 '$ mbed export -i simplicityv3'
- 8 '$ ls'
posted by Antonello Lombardinilo 01 Mar 2017

Update!

I repeated all the steps necessary on OS Win7x64. I again the problem undefined reference to '_wrap_calloc_r' In this case the library build downloaded is the f9eeca106725

How can I force a different version from f9eeca106725?

f9eeca106725 does not seem to be a revision of mbed. OTOH, I'm glad that updating worked for you!
