Hyperledger-fabric fails to instantiate chaincode

I am unable to instantiate chaincode in Hyperledge Fabric.

When executing:

peer chaincode instantiate -o orderer -n test_cc -C test-channel -v 0.1 -c '{"Args":["initLedger"]}'

I get the error:

peer0       | 2018-04-17 13:02:11.097 UTC [dockercontroller] Start -> ERRO 046 start-could not start container: API error (400): {"message":"OCI runtime create failed: container_linux.go:348: starting container process caused \"exec: \\\"chaincode\\\": executable file not found in $PATH\": unknown"}

When searching the internet, the error message is the same as on the original post at [OCI Runtimer Error when installing Hyperledger Chaincode via Java-SDK and [OCI runtime error when sending Hyperledger Fabric's chaincode instantiation request to peers, but the comments on these posts did not led me to the solution.

I am using the following software versions: Hyperledger 1.1.0 Docker version 18.03.0-ce (on Linux), Hyperledger Docker images: x86_64-1.1.0

The following steps succeed:

(Steps according to Hyperledger documentation: [http://hyperledger-fabric-docs.readthedocs.io/en/latest/chaincode4noah.html])

In the CLI Docker container, files are located in the directory /opt/gopath/src/chaincode/go/test_cc/, where 4 files are present: test_cc, test_cc.go, test_cc_pack.out, test_cc_signed_pack.out (the binary, source file, packaged file and signed package file).

The full output of the orderer and peer is:

orderer    | 2018-04-17 13:29:44.648 UTC [orderer/common/server] func1 -> DEBU 16a Closing Broadcast stream

It looks like there is some path issue, but the process of the creation of the chaincode container and the variables which influence this process.

I'm messing around with this issue for few days(!) now, tried all path combinations like placing the file in /opt/gopath/bin, etcetera, but to no avail.

Someone who can shine a light on this issue? Or knows what the correct paths are and where they are, or where they should be defined?

Thanks

The issue was that in the Go source files I used 'package test_package', which, when building, does not create an executable file, but a linkable object file.

Having 'package main' in my Go files, then rebuilding and repackaging, made the 'peer chaincode install' and 'peer chaincode instantiate' commands working as expected.
