Bazel asks for interactive questions

[dml33]

Hi.

I have just tried to compile your FreeBSD port for Tensorflow 1.15 in a FreeBSD 12.2-RELEASE-p11 jail with NOAVX support.

I noticed that, at the beginning of the making process, bazel asks for interactive questions as it was happening in the original photoprism-freebsd-port long time ago:

Preconfigured Bazel build configs. You can use any of the below by adding "--config=<>" to your build command. See .bazelrc for more details.

huo-ju fixed it huo-ju/photoprism-freebsd-port@5a6019d

I think that a couple of things are missing in the Makefile, such as:

• TF_NEED_MPI=0
• For the OpenCL SYCL, huo-ju made it as an option at the make configure stage:

TF_NEED_OPENCL_SYCL_DESC=       OpenCL SYCL
TF_NEED_OPENCL_SYCL_VARS=       TF_ENV+="TF_NEED_OPENCL_SYCL=1"
TF_NEED_OPENCL_SYCL_VARS_OFF=   TF_ENV+="TF_NEED_OPENCL_SYCL=0"

• And maybe these last options could help with all the warnings at compile stage and use all the instruction set supported by the given processor:

TF_DOWNLOAD_CLANG=0 CC_OPT_FLAGS="-march=native -Wno-sign-compare" 

Thanks!

+1. As long as there is no solution to this, you could use the program "expect" to supply user input into the pipe.
