Hi! I’m trying to build a command-line tool for non clojure using colleagues (or not yet 🙂 ). We need to run on linux (centos and ubuntu). I’ve used this docker image to create the native image.

# Dockerfile 
FROM 
WORKDIR /opt/graalvm
RUN gu install native-image
ENTRYPOINT ["native-image"] # // building the image
# docker build -t graalvm-native-image .

native-image-linux {:depends [uberjar]
                      :task (do
                              (def native-image-cmd
                                (str/join " "
                                          ["docker" "run" "--rm"
                                           "-v"
                                           (str (cd) "/:/opt/cp")
                                           "-v"
                                           (str (cd) "/:/opt/graalvm")
                                           "graalvm-native-image"
                                           ;; "-J-Xmx3g"
                                           ;; "-R:MaxHeapSize=3.5g"
                                           "-H:Name=dataloader"
                                           "-H:+ReportExceptionStackTraces"

                                           "--no-server"]))
                              (println "running: " native-image-cmd)
                              (shell native-image-cmd))}

@bocaj Is this a question or just an informative statement? ;)

Oops, hit the wrong keys, updating now

Broadly looking for help on how to debug this type of issue

What distribution is this base image based upon? I usually use ubuntu

Does centos have glibc?

I was just trying to round-trip the docker image that I used to build the native image

but maybe native image builds without have the libs required to run it

" I get “missing file” errror."

can you be more specific?

I usually see such a message when I build a dynamic image and run it on a system that doesn't have glibc

so you could either try a static (muslc) based build or try running the image in ubuntu (or centos)

ok, Thanks for pointing me in a direction. I’ll look through your CI configuration for more help as well. Is there a project of yours that has a simple CI build or docker? I’d prefer to build on my laptop for simplicity

yes, e.g. babashka or clj-kondo

what I usually do is run in ubuntu (in CI), then download graalvm via curl, etc. then build. and then copy the image into a docker image (to provide docker images with the binary in it, but this is optional)
