cryptogen: cannot execute binary file: Exec format error

Question

cryptogen: cannot execute binary file: Exec format error

ronaldl29 opened this issue 5 years ago · 14 comments

Environment: Ubuntu 18.04
Node.js v8.14.0
NPM v6.13.4
Go 1.13.6

When I get to the step where I run:

./byfn.sh generate -o etcdraft

This is my output:

Generating certs and genesis block for channel 'mychannel' with CLI timeout of '10' seconds and CLI delay of '3' seconds
Continue? [Y/n] y

What is your python version?

as shown in the Hyperledger Fabric dependencies (which this guide is based on - https://hyperledger-fabric.readthedocs.io/en/release-1.4/prereqs.html) you will need Python 2.7.

The following applies to Ubuntu 16.04 users only.

By default Ubuntu 16.04 comes with Python 3.5.1 installed as the python3 binary. The Fabric Node.js SDK requires an iteration of Python 2.7 in order for npm install operations to complete successfully. Retrieve the 2.7 version with the following command:

sudo apt-get install python
Check your version(s):

python --version

I think this post may be the answer to your question - siyuyifang/balance-transfer-java#1

Answer 3 · 2020-01-26T18:20:09.000Z

@horeaporutiu
My python version is 2.7.17. Not sure if it matters but HLF is running fine on my machine when executing the first network from fabric-samples.

Answer 4 · 2020-01-27T17:49:45.000Z

@ronaldlong46

Got it - It seems to be because when you download Fabric binaries, they automatically sync with the platform you are using. Since I am using macOS it is different than Ubuntu so the binaries are not working properly.

I will rearrange the repo and change the steps to make sure the binaries will work for Ubuntu users. Stay tuned!

@ronaldlong46

I've just updated the steps for Linux users. Please see this part of the README. Let me know if this solves the problem. https://github.com/IBM/raft-fabric-sample#for-linux-users

Answer 6 · 2020-01-28T03:11:11.000Z

Thanks! You're awesome @horeaporutiu
I'm at step 3 (on the regular instructions). When I run this command:
./byfn.sh up -o etcdraft -l node

I get:

Error: could not assemble transaction, err proposal response was not successful, error code 500, msg error starting container: error starting container: API error (404): network _byfn not found
!!!!!!!!!!!!!!! Chaincode instantiation on peer0.org2 on channel 'mychannel' failed !!!!!!!!!!!!!!!!
========= ERROR !!! FAILED to execute End-2-End Scenario ===========

ERROR !!!! Test failed

Answer 7 · 2020-01-28T19:13:46.000Z

@ronaldlong46 Could you post the logs from peer0 org2?

you can do this by doing docker ps command and then docker logs <containerID of peer0org2 >

I see a similar error here - maybe this Stack post will help: https://stackoverflow.com/questions/46775044/error-when-try-to-instantiate-chain-code-on-hyperledger-fabric

You've also made sure that you did ./byfn.sh down and then docker stop $(docker ps -a -q) ; docker rm -f $(docker ps -aq) ; docker system prune -a ; docker volume prune ; docker ps -a ; docker images -a ; docker volume ls
before starting step 3 right?

Answer 8 · 2020-01-28T20:26:58.000Z

Yes, I ran the steps to clear existing docker containers prior to going to step 3. I will go through that link. Here are my logs for peer0org2: @horeaporutiu

Ok I've updated the instructions again. I just checked and it worked with my Ubuntu 18.04 machine.
Node version 8.10.0.

I've updated the instructions again. Note that it's important that you run all commands (byfn, etc) from the first-network folder inside the fabric-samples repo. Since the fabric-samples repo will have all the correct binaries for cryptogen that was giving us problems before. Try using the updated instructions again.

@ronaldlong46 I was having this same issue and can confirm that following @horeaporutiu updated instructions now works.

Thanks for both of you, I'm using Ubuntu 19.10 by the way.

Hello. Congratulations for your work, super job...
I did'nt see your linux remarks when I first cloned your code. I founded another way to get around.
I had another LUbuntu 18.04 LTS VM (in VirtualBox) with tries and tests on HLF 1.4.4. It was then very easy to copy the bin directory content from original HLF first-network sample (8 files) to my local directory in your example, and that's all.
Once more : a very demonstrative job. Thank's. I'll stay connected.

@dvauze

Thanks. That's actually much easier than my steps :)

Will update those when i get a chance. Thanks for your comment!

Answer 13 · 2020-02-05T23:11:43.000Z

Sorry the late reply. It's working! I still ran into an issue, one of the commands was downloading HLF 2.0 and the fabric versions weren't matching. I got around this by downloading binaries of a specific version by running:

curl -sSL http://bit.ly/2ysbOFE | bash -s -- 1.4.4 1.4.4 0.4.18

Thank you so much for your help!

Answer 14 · 2020-02-06T20:46:17.000Z

@ronaldlong46 will update the directions accordingly. Thanks for the update.
