undefined: ibmmq.MQCNO after upgrading to golang 1.21.1 #68

Sparkz0629 · 2024-07-06T08:40:53Z

Hi.

We are busy with a golang upgrade from 1.15 to 1.21.1 across our microservices

One of the services uses the mq-golang-jms20 module.

When attempting to build the code in the new env, we get the following:

# github.com/ibm-messaging/mq-golang-jms20/jms20subset
/go/pkg/mod/github.com/ibm-messaging/[email protected]/jms20subset/MQOptions.go:5:32: undefined: ibmmq.MQCNO
/go/pkg/mod/github.com/ibm-messaging/[email protected]/jms20subset/MQOptions.go:8:25: undefined: ibmmq.MQCNO

this is our build stage:

build:
  stage: build
  only:
    refs:
    - master
  image: ${BUILD_IMAGE}
  script:
    - mkdir -p /opt/mqm
    - chmod a+rx /opt/mqm
    - export genmqpkg_incnls=1
    - export genmqpkg_incsdk=1
    - export genmqpkg_inctls=1
    - cp 9.2.4.0-IBM-MQC-Redist-LinuxX64.tar.gz /opt/mqm/
    - tar -zxf /opt/mqm/*.tar.gz
    - rm -f /opt/mqm/*.tar.gz
    - export LD_LIBRARY_PATH=.:/opt/mqm/lib64:/opt/mqm/java/lib64:$LIBPATH
    - export PATH=.:/opt/mqm/bin:$PATH
    - bin/genmqpkg.sh -b /opt/mqm
    - img build -t ${DOCKER_PUSH_URL}/mq-transfer-server:2.0 --build-arg GO_IMAGE=${GO_121_IMAGE}  .
    - echo "build done"
    - echo ${ENCODED_PASSWORD} | base64 -d | img login --username ${USER} --password-stdin ${DOCKER_PUSH_URL}
    - img push ${DOCKER_PUSH_URL}/mq-transfer-server:2.0
    - img logout ${DOCKER_PUSH_URL}

where GO_121_IMAGE is an image built from the below with our certificates added.

FROM golang:1.21.1-bookworm
ENV GOOS=linux 
ENV GOARCH=amd64 
ENV CGO_ENABLED=0

BUILD_IMAGE is FROM debian:12.1-slim with our certificates added.

Looking for any advised or assistance on the above... out of 15 microservices, this is the only one that we are stuck on the upgrade with. (Also the only one to use to mq libraries)

The text was updated successfully, but these errors were encountered:

Hi @Sparkz0629 - thanks for getting in touch.

I've updated the "openshift-app-sample" directory (which uses docker/podman to build the image in a similar way that you're using above) to use Golang 1.21.1 using this commit and it ran successfully on my Ubuntu VM.

So I suggest looking to see what the differences are between your build and the openshift-app-sample Dockerfile.

Some particular areas to investigate are:

Update your MQ client library to the latest 9.4.0.0-IBM-MQC-Redist-LinuxX64.tar.gz (it's backwards compatible with other queue manager versions)
Check your go.mod (+go.sum) files to ensure they point at the correct 1.11.0 version of mq-golang-jms20 and the related v5.6.0 version of mq-golang respectively
there is a similar error in this recent Stackoverflow question where in that case the issue looks to be a mismatch between different platform types, so that's worth checking into as well

Thanks @matrober-uk for the quick response.
Ive updated to the latest Redist file, and also conformed that the correct versions of mq-golang-jms20 and the related mq-golang or where we want to see them.

Still combing through to see if there are other differences.

Sparkz0629 · 2024-07-08T08:40:55Z

there is a similar error in this recent Stackoverflow question where in that case the issue looks to be a mismatch between different platform types, so that's worth checking into as well

This is running on a gitlab runner based on gitlab/gitlab-runner:alpine-v14.9.0.
To the best of my knowledge, this should mean the IBM-MQC-Redist-LinuxX64.tar.gz should be fine.

Also, something to note, the genmqpkg.sh runs fine:

$ bin/genmqpkg.sh -b /opt/mqm
Generate MQ Runtime Package
---------------------------
This program will help determine a minimal set of runtime files that are
required for a queue manager installation or to be distributed with a
client application. The program will ask a series of questions and then
prompt for a filesystem location for the runtime files.
Note that IBM can only provide support assistance for an unmodified set
of runtime files.
The MQ runtime package will be created in
/opt/mqm
Generation complete !
MQ runtime package copied to '/opt/mqm'

The failure occurs during the build stage:

You have set ENV CGO_ENABLED=0 which disables the C compilation phase. If I add that to Matt's Dockerfile, then it fails in the same way. Either remove that line, or set the value to 1 which might be clearer as to intention.

Thanks for this.

So i updated this and the build succeeds, the issue we have then is that the code doesnt run because of the below, which was the actual reason we added that flag:

/lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.32' not found (required by /usr/bin/kaas-mq-transfer-server)
/lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by /usr/bin/kaas-mq-transfer-server)

ibmmqmet · 2024-07-10T13:14:19Z

That is telling you that the container you are running on does not have an appropriate level of glibc installed.

The MQ 9.4 client library is built on RHEL8, so whatever glibc is in there will be the minimum for any other distro-based container. And that excludes anything using the musl libc typically used in alpine containers, and which is completely incompatible.

Sparkz0629 · 2024-07-10T14:32:25Z

So that happens even when running with the golang:1.21.1 runner image

Our cluster has RHEL 8.9 boxes as the underlying servers.
The gitlab runner is alpine based
and the runner images are debian based.

We had this issue in the past, and the only way we got around it was by setting the CGO_ENABLED to 0 on the build stage.

What is weird, is that using the exact same process for version golang 1.15 and 9.2.4.0 of the MQ Distro, all works 100% (Without having to set CGO_ENABLED). That runner image was debian:11.3-slim. As soon as we attempt to run on a later image like debian:12.1-slim we get the above.

Sparkz0629 · 2024-07-11T10:02:02Z

I decided to go back to the drawing board and attempt this step by step using the sample app initially supplied by Matt.

The code build works now.

Our image build and push step runs the following dockerfile:

FROM golang:1.21.1

COPY kaas-mq-transfer-server /usr/bin/kaas-mq-transfer-server

RUN mkdir -p /opt/mqm \
    && chmod a+rx /opt/mqm

ENV genmqpkg_incnls=1 \
    genmqpkg_incsdk=1 \
    genmqpkg_inctls=1 

COPY 9.4.0.0-IBM-MQC-Redist-LinuxX64.tar.gz /opt/mqm/

RUN cd /opt/mqm \
    && tar -zxf ./*.tar.gz \
    && rm -f ./*.tar.gz \
    && bin/genmqpkg.sh -b /opt/mqm

ENTRYPOINT [ "/usr/bin/kaas-mq-transfer-server" ]

I can also run this manually by spinning up the local image and running the commands one by one.
As soon as it tries to run in the pipeline, i get the following on the genmqpkg.sh step:

Building kaas-mq-transfer-server:v0.0.19
Setting up the rootfs... this may take a bit.

#9 9.253 Generate MQ Runtime Package
#9 9.253 ---------------------------
#9 9.253 This program will help determine a minimal set of runtime files that are
#9 9.253 required for a queue manager installation or to be distributed with a
#9 9.253 client application. The program will ask a series of questions and then
#9 9.253 prompt for a filesystem location for the runtime files.
#9 9.253 
#9 9.253 Note that IBM can only provide support assistance for an unmodified set
#9 9.253 of runtime files.
#9 9.253 
#9 9.2[95](kaas-mq-transfer-server/-/jobs/2309432#L95) 
#9 9.295 The MQ runtime package will be created in

#9 9.295 The package MANIFEST does not exist; no files can be removed from the MQ runtime package.

Ive edited the dockerfile and confirmed that the tar is getting extracted as expected and the file is present.

So atleast making progress as the initial build works, but now the image build and push doesnt.
