TDA2PXEVM: C++14 for RTOS

Hi,

Please take a look at this thread

Also mention which BIOS version, SDK version and compiler version.

Regards

Vineet

Yes, we are compiling C++ code, but especially C++14 we are facing this error message:

gcc-arm-none-eabi-4_9-2015q3/arm-none-eabi/include/c++/4.9.3/bits/c++14_warning.h: 

#error This file requires compiler and library support for the forthcoming \

ISO C++ 2014 standard. This support is currently experimental, and must be \

enabled with the -std=c++1y or -std=gnu++1y compiler options.

Any update for this topic?

Sorry for the delay, can you try with the flag CFLAGS += -std=c++11 ?

Regards

Hello Vineet,

I am the FAE working with this customer. They use the TDAx Vision SDK v3.8 on Windows. Our user's guide require that the GCC ARM tools 4.9-2015-q3-update be installed. On the other hand, my customer's application uses some third=party code that uses C++14. I am still trying to find out which features of C++14 they need, but the trouble is anyway that the above GCC version only has experimental support for C++14.

From what I see (link), my customer may require GCC 5.x. Have we already validated a GCC version more recent than 4.9 with our Vision SDK? Thank you.

Best regards,
François.

Francois,

Can you please clarify on which core you are trying to build the C++ code for and which tool chain is being used? You mentioned "gcc-arm-none-eabi-4_9-2015q3", but please double check.

If I look into the Vision SDK 3.8, it is recommended to use GCC 8.3 version and therefore I want to know how you/customer choose the GCC 4.9 and then make required corrections.

Hello Karthik,

My customer develops for TDA2P and referred to the corresponding Vision SDK UG (file:///C:/ti/PROCESSOR_SDK_VISION_03_08_00_00/vision_sdk/docs/UserGuides/VisionSDK_UserGuide_TDA2px.pdf). Its System Requirements section requires to install this version of the GCC ARM tools for the Cortex A15 core: launchpad.net/gcc-arm-embedded/+milestone/4.9-2015-q3-update

Best regards,
François

Francois,

I believe that this is incorrect. I will investigate this further and make another post, but for now can you please try to use https://developer.arm.com/-/media/Files/downloads/gnu-a/8.3-2019.03/binrel/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf.tar.xz
