I am trying to build edgex app-service-configurable using cross-compilation.
Here I am using riscv sdk created from yocto.

Following is the error I am facing:

/home/root/workspace/sysroots/x86_64-oesdk-linux/usr/libexec/riscv64-oe-linux/gcc/riscv64-oe-linux/10.2.0/real-ld: $WORK/b068/_x008.o: in function x_cgo_thread_start': ../workspace/sysroots/riscv64-oe-linux/usr/lib/go/src/runtime/cgo/gcc_util.c:21: undefined reference to _cgo_sys_thread_start'
collect2: error: ld returned 1 exit status

You didn't even include the commands you're running, there's not much to work with here. The New Issue template has several questions, but you just deleted it, which is not... great.

Anyway I don't think riscv64 supports external linking in Go 1.15; you may have more luck with Go 1.16. Please try it.

Sorry for my inconvenience @ALTree
As you suggested, I was able to eliminate the error I was facing.
Thankyou.
