Compile errors when installing required module in opennao VM and NAO Robot OS (based on Gentoo OS)

[chan71]

In which file did you encounter the issue?

https://github.com/GoogleCloudPlatform/python-docs-samples/blob/master/speech/grpc/requirements.txt

Did you change the file? If so, how?

No

Describe the issue

In order to run transcribe_streaming.py, I had to install the following modules among other things as per requirements.txt
grpcio==1.0.3
grpc-google-cloud-speech-v1beta1==0.11.1

When tried to install these on opennao vm (GNU/Linux distribution based on Gentoo), compiler errors were noted.
CompileError: command 'i686-pc-linux-gnu-gcc' failed with exist status 1

What could be the reason for above modules not getting installed in opennao vm.

More observations

1. pip.log says

• pip.log.grpcio at line 2077 shows termination due to stdalign.h

• pip.log.grpc-google-cloud-speech-v1beta1 at line 1781 shows termination due to stdalign.h

• Both module or package terminated due to stdalign.h

2. Installation Steps in OpenNaoVM:
   a. Install portaudio using emerge - OK
   b. Install pyaudio using emerge - OK
   c. Install package as per requirements.txt
   - google-cloud-core==0.22.1 - OK
   - grpcio==1.0.3 - FAIL
   - PyAudio==0.2.9 - OK
   - grpc-google-cloud-speech-v1beta1==0.11.1 - FAIL
   - six==1.10.0 - OK
   d. python transcribe_streaming.py – Throws an error

3. We used the OpenNao VM that define in this URL http://doc.aldebaran.com/1-14/dev/tools/vm-intro.html. We saw “binaries are built for i486 targets” in the snapshot as below but OS is i686. Not sure this cause the error.

@chan71 thanks for the detailed report.

1. Can you tell me which version of pip you're using? grpcio distributes manylinux wheels, so there shouldn't be any compilation unless you have an old pip or a very unique linux environment.
2. If you do need to build grpc, you'll need your distributions' equivalent of debian's build-essential, autoconf, and libtool packages.

@jonparrott you are right. my opennao VM box has pip 1.0.2 where as the windows machine has pip 9.0.1. Does pip 1.0.2 needs compilation? If so, should I upgrade pip in opennao VM and try out?

[theacodes]

@chan71 yeah pip 1.0.2 doesn't have wheel support. I highly, highly recommend updating because 1.0.2 was released in 2011.

I'm going to go ahead and close this issue, but feel free to continue to comment if you need any more assistance.

@jonparrott thanks a lot for your insights into this issue. I will upgrade the pip and let you know.

@jonparrott after updating the pip in the opennao VM, we were able to proceed installing grpcio and grpc packages. We could run the latest sample but it threw an error due to input device (mic) not being present in the vm. I think this is fine.
