Unable to use --target option during native-image command

[amrutprabhu]

Describe the issue
When I use the --target option to build a target architecture image, the native-image command fails with an output

Error: Unrecognized option: --target

I am currently using a native-maven-plugin from org.graalvm.buildtools to build my image.

My laptop is MacBook pro M2
macos: 13.3.1
graalvm version : GraalVM CE 22.3.0

I installed graalvm jdk using Sdkman.

Now, picked out the command that the plugin ran, and I have reduced the full command and removed the -cp option.

/Users/ap/.sdkman/candidates/java/22.3.r19-grl/bin/native-image \
--no-fallback \
-H:Path=/Users/ap/projects/home-assistant/Home-Assistant/target \
-H:Name=Home-Assistant \
-H:ConfigurationFileDirectories=/Users/ap/projects/home-assistant/Home-Assistant/target/graalvm-reachability-metadata/bae22b6d4f0631f4339c34681a2baf10e3887c14/org.apache.tomcat.embed/tomcat-embed-core/10.0.20,/Users/ap/projects/home-assistant/Home-Assistant/target/graalvm-reachability-metadata/bae22b6d4f0631f4339c34681a2baf10e3887c14/ch.qos.logback/logback-classic/1.4.1 \
--target linux-amd64

Even If I run it independently, it fails. ( without the -cp option) it gives me the same error.

I am trying to build a native image that I can run on an Ubuntu machine.

Hi @amrutprabhu, thanks for reporting the bug. We'll look into it.

I am trying to build a native image that I can run on an Ubuntu machine.

--target will unfortunately not help you with this as Native Image does not support cross-compilation yet. To generate Linux binaries on a macOS machine, please use a containerized environment for now. Or generate binaries for different platforms on CI, for example using GitHub Actions.

[amrutprabhu]

ok. I was referring to the build options from here: https://docs.oracle.com/en/graalvm/enterprise/22/docs/reference-manual/native-image/overview/BuildOptions/
If you say it's not supported yet I can use the alternative you mentioned.

Note that the correct way to use the option is --target=linux-amd64.
