samplecode/helloworld

Hello,
I have problem with compilation a helloworld sample code .

I tried compilation on below docker images:
baiduxlab/sgx-rust:2004-1.1.3
baiduxlab/sgx-rust:1604-1.1.3
baiduxlab/sgx-rust:centos8-1.1.3

But each time, I obtained error:

--- stderr
: not found/sgx_unwind/../sgx_unwind/libunwind/autogen.sh: 2:
: not found/sgx_unwind/../sgx_unwind/libunwind/autogen.sh: 5:

make[1]: Leaving directory '/root/sgx/samplecode/helloworld/enclave'
make: *** [Makefile:165: enclave] Error 2

I found addition informations

Compiling sgx_unwind v1.1.4 (/root/sgx/sgx_unwind)
error: failed to run custom build command for `sgx_unwind v1.1.4 (/root/sgx/sgx_
unwind)`

Caused by:
process didn't exit successfully: `/root/sgx/samplecode/helloworld/enclave/tar
get/release/build/sgx_unwind-917f9251756f26e8/build-script-build` (exit status:
1)

Is someone who can help me ?

Reproduce the failure in samplecode/helloworld using one of the listed Docker images, then read samplecode/helloworld/enclave/Makefile and sgx_unwind/../sgx_unwind/libunwind/autogen.sh. Check the reported build-script and autoreconf errors first. Done means the helloworld enclave compiles successfully in a documented environment.
