AM5716: [Cross Compile] Cross compilation toolchain compilation error

zhicheng zhang

Part Number: AM5716

I refer to the following guide document to use the cross compilation toolchain in SDK9.2 to compile applications, but an error occurred and I couldn't find the header file. May I ask why the cross compilation toolchain in the installed SDK is missing the header file?

Hello Zhicheng,

Can you try sourcing the environment script? as explained below on the page?

Hello Zhicheng,

The first error happens because you are not passing the sysroots,

So this can be alleviated by passing the --sysroot=<PATH_TO_SYSROOT> or sourcing the environment setup as mentioned before.

So that's when you get to the next issue:

zhicheng zhang said:

This is due to not using the same compilation options for this particular processor or ABI (Application Binary Interface) as the source files. This will be fixed by passing the correct ARM compilation Flags:

-march=armv7-a -mthumb -mfpu=neon -mfloat-abi=hard

Example:

The paths and Flags can all be found in the Rules.make file in the top SDK directory.
