panic: Version is not set for fabric-ca library

Question

I followed the below link to install hyperledger fabric ca:

http://hyperledger-fabric-ca.readthedocs.io/en/latest/users-guide.html#setting-up-multiple-cas

which specifies the below command to install:

go get -u github.com/hyperledger/fabric-ca/cmd/...

I have all the dependencies:

Go version: 1.9.6

GOPATH environment variable is set correctly

libtool and libtdhl-dev packages are installed

However, when I run the fabric-ca-server natively, I get the following error:

In words, the error is shown below:

How do I set the version for the fabric ca library? Can some one help me?

Answer 1

The following procedure solved the problem for me:

The error message said: 'go/src/github.com/hyperledger/fabric-ca/lib/metadata/version.go:58 +0x60'. A peek into the version.go file showed me the following comment:

// Version specifies fabric-ca-client/fabric-ca-server version

// It is defined by the Makefile and passed in with ldflags

Hence, I did a make from go/src/github.com/hyperledger/fabric-ca/. During the make, the below message was printed to the screen:

[INFO] Server Version: 1.1.1-snapshot-e656889

After the make, when I start the fabric-ca-server present in go/src/github.com/hyperledger/fabric-ca/bin, its running fine!
