C SDK Cross Compile

Hello all,

I try to cross compile C SDK thingworx on R700 impinj RFID reader (linux arm).

My host en is ubuntu x86 architecture.

Impinj Reader provide the tool chain to compile sources, but i don't know exactly how to configure it to compile thingworx sources too

Is there a document how to cross compile C SDK with a provided tool chain librairy ?

I join the compile guide of reader and the error message.

Thank you for your help
