We need a compiler that supports std=C++11.

[kilsoo_choi]

Hello

We are developing using the IMX.6 quad.
During software development
Protobuf needs to be cross-compiled and the "-std=c++11" build option is required.
However, our compiler (fsl-linaro-toolchain Ver:4.6.2)
"-std=c++11" is not supported, so the build will not work.
I need a higher version of the compiler, do you support it?

Thank you.

Hello kilsoo,

In order to export higher version of toolchain, you should follow these steps.

For example, assume you are using L4.19.35_1.1.0 BSP

1. Download documents for the version of linux BSP

Embedded Linux for i.MX Applications Processors | NXP 

2. Setup environment of Yocto BSP

Follow steps in i.MX_Yocto_Project_User's_Guide.pdf to set up environment of Yocto BSP, and compile it successfully.

3. export the toolchain from Yocto BSP

Follow steps described on standalone operations in i.MX_Linux_User's_Guide.pdf to export toolchain, and install it to /opt directory.

see "4.5.12 How to build U-Boot and Kernel in standalone environment" of the document, please!

if you want to get other version of toolchain, use the similar steps, please!

Hope these information is helpful to you.

Have a nice day!

B.R,
