Compile errors with Mbed CLI

[John Greene]

I’m trying to compile the AUTO_OTA_EXAMPLE from the Dot-Examples program for mDot using the Mbed CLI. I imported dot-examples and added LibmDot-mbed5 and mbed-os-5.4.7. Trying various configurations, I always get errors with “[abi:cxx11]” and “ __CXX11”. Following is an example:

I have tried using the -D_GLIBCXX_USE_CXX11_ABI=0 macro and using older versions of the GCC toolchain although nothing resolves the issue.

[Jason Reiss]

What gcc arm version are you using?
Have you tried gcc-arm-none-eabi-6-2017-q2-update?

[Matt Brown]

I’ve also tried to build Dot-Examples using GCC ARM, although I’m building OTA_EXAMPLE rather than AUTO_OTA_EXAMPLE.

The first undefined reference I see is mDot::getReturnCodeString.

Initially I was using ‘6 2017-q2-update’, which was installed by Mbed CLI. But, I’ve also tried ‘7 2017-q4-major’.

I changed to the online compiler but would much rather be using the CLI and ARM GCC.

HTH,
Matt

[Ryan Klaassen]

Have you tried GCC 4.9? If using mbed-5.4.7 GCC 4.9 is recommended.

[Matt Brown]

I have now.

I downloaded Arm GCC 4.9 from launchpad, it took me a while to find it. I went for 2015 Q3 update.

https://launchpad.net/gcc-arm-embedded/4.9

Now I can link.

Thanks,
Matt

[John Greene]

I used GCC-4.9 2015q3 because that is what was apparently used to compile mbed-0S-5.4.7 which, in turn, was used for mdot-library rev 3.0.0. I also tried with GCC-6 2017-q2-update the resultant log for which I provided upthread.

I just switched back to GCC-4.9 and ran it again before clicking “Submit” on this thread and it worked. Who knows, most likely user error. Thanks for your feedback/help.
