  2. Install fabric-chaincode-java to raspberry 4

Yes I found the trick with the binutils-gold. I made the changes to the Dockerfiles and I think that is enough. So I can build the fabric and the fabric-ca docker image and the native. The problem remains with the fabric-chaincode-java, I managed to compile the grpc after installing protobuf with the appropriate flags. Therefore, I add it to the maven local repository as suggested. However, the problem with the build of fabric-chaincode-java remains as it was. I don't know maybe I have to set some paths or envs.

Finally, if I make all this work I can write the steps to add it in your wiki.

Also, the ld failure I believe can be solve by adding the binutils-gold package to the image. You can see the same problem on ARM was solved here for the fabric images:  https://github.com/hyperledger/fabric/commit/33886a4febc58f7d5f1278fe2246daffb31067a7

Hello, I would like to build latest version of hypeledger fabric into a raspberry 4 (using java). As I can see in the bash script used by curl here (latest installation) the versions that are used are:

  • fabric 2.3.1
  • fabric-ca 1.4.9
  • fabric-chaincode-java 2.3.1

Unfortunately, there are not pre-built images for all these repositories so I have to build them from source. In order to build fabric 2.3.1 I can make some changes to the Dockerfile (as in master branch i.e add binutils-gold) in order to support raspberry. Respectively, I can do the same for the fabric-ca 1.4.9. The real problem is the fabric-chaincode-java 2.3.0 (there is no 2.3.1 tag in github!!), I have the same problem as here so I try to follow the suggested instructions but I fail. Specifically, when I run ../gradlew java_pluginExecutable -PskipAndroid=true

I end up with a message:

....

/usr/bin/ld: /usr/local/lib/libprotoc.a(plugin.pb.o):(.data.rel.ro+0x0): undefined reference to `descriptor_table_google_2fprotobuf_2fdescriptor_2eproto'
collect2: error: ld returned 1 exit status
FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':grpc-compiler:linkJava_pluginExecutable'.

      Linker failed while linking protoc-gen-grpc-java.

Are they any instructions with the prerequisites in order to build it?  Note that there is a  pre-build image but for the version 2.2.0 so there is way to build it. Finally, I have not seen any information about the compatible versions of the different repositories, for example can I use fabric 2.3.1 with the 2.2 fabric-chaincode-java or I would have a version mismatch? Thus, which versions are compatible with each other?

Thanks,
