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 24 Feb 2017I run the whole procedure again, and the problem has apparently disappeared!
My OS is Debian Jessy.

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'
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?
