Install fabric-chaincode-java to raspberry 4 #fabric-chaincode #fabric-questions

Nikos Karamolegkos
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:
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' 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, -- Nikos Karamolegkos R & D engineer at ICS-FORTH Telecommunications and Networks Lab (TNL)

Hello; - The docker image you mention is from one of those that I know has done the build; normally the prereqs don't need building - so I can't really give you any pointers there I'm afraid.

Somewhere I have the instructions on how to build this, but the net-net is, the Java protobuf library doesnt have a native distribution for ARM. You need to clone the protobuf repo (which will also have a missing dependency that will require you to build it as well, though I can't remember off the top of my head which one), and you will need to build it, and deploy it to your local maven repo on your machine, so the chaincode-java build process can find these two dependencies prebuilt in your local maven repo. I'll try to dig up the RocketChat post, or mailing list post where I gave detailed instructions on doing this, but it's been a while and I'm not confident I'll find it. Brett Logan

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

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.

Hello, I have built
1) protobuf 3.12.0 using ../autogen, /configure, make, make check, sudo make install. No problems, the protobuf pack is installed in usr/local/lib 2) export LDFLAGS="-L/usr/local/lib/", export CXXFLAGS="-I/usr/local/include/". Not sure if needed 3) From grpc/compiler I run: a) ../gradlew java_pluginExecutable -Pprotoc=/usr/local/bin/protoc -PskipAndroid=true OK b) ../gradlew test -Pprotoc=/usr/local/bin/protoc -PskipAndroid=true OK c) ../gradlew publishToMavenLocal -PskipAndroid=true -Pprotoc=/usr/local/bin/protoc OK after changing assertEq "$format" "elf64-little" $LINENO to assertEq "$format" "elf64-littleaarch64" $LINENO.

I believe you need to add `mavenLocal()` to https://github.com/hyperledger/fabric-chaincode-java/blob/master/fabric-chaincode-protos/build.gradle#L13 like it is mentioned here: https://github.com/hyperledger/fabric-chaincode-java/blob/master/build.gradle#L23 The protos don't import your local maven repo.

I have already tried that. The same error.

I changed the grpc version to build.gradle file from 1.23.0 to 1.37.0-SNAPSHOT (latest) which was installed to local mvn repo and I solved the issue.No I have an new one :( | Results: FAILURE (229 tests, 227 successes,
1 failures, 1 skipped) | I checked the previous index.html file and the only failure I can
see is: <td class="failures"> I am looking to it. Any ideas? -- Nikos Karamolegkos R & D engineer at ICS-FORTH Telecommunications and Networks Lab (TNL)

Brett did you find anything about rapsberries? Is there a list for fabric-chaincode-java with people willing to help?

I decided to apply a workaround and set as comments the part of the test creating this problem (Will this be a problem?). I just want to see what is coming next. So, the next problem is that adoptopenjdk/openjdk11:jdk-11.0.4_11-alpine used by the Dockerfile does not exist for arm64. So the error is
> Task :fabric-chaincode-docker:buildImage Step 1/38 : FROM adoptopenjdk/openjdk11:jdk-11.0.4_11-alpine as builder > Task :fabric-chaincode-docker:buildImage FAILED :fabric-chaincode-docker:buildImage (Thread[Execution worker for ':' Thread 2,5,main]) completed. Took 5.526 secs. FAILURE: Build failed with an exception. * What went wrong: Execution failed for task ':fabric-chaincode-docker:buildImage'. > Could not build image: no matching manifest for linux/arm64/v8 in the manifest list entries Can I replace it with something else?
