Bob cannot find oggz-validate on Linux

[hillsofsteel]

Is it a private platform, and a platform specific issue? (i.e. would it break your NDA?)

Then please report your issue in the corresponding extension repository!

Describe the bug (REQUIRED)
Building wasm with bob.jar in a GitLab runner with an Alpine Linux image, build step fails if you have .ogg sounds in the project due to
java.io.IOException: Cannot run program "/tmp/13879549146032368337/x86_64-linux/oggz-validate": error=2, No such file or directory

Build completes successfully with the same command and environment if there are no sound files in the project.

To Reproduce (REQUIRED)
Steps to reproduce the behavior:

1. Deploy VM from eclipse-temurin:17-alpine image (not tested other linux distros)
2. (Optional) Install missing packages: libxext libxi luajit libstdc++ liboggz
3. Download bob.jar
4. Command used: java -jar bob.jar --archive --platform js-web --architectures wasm-web --liveupdate yes --texture-compression true --variant debug resolve distclean build bundle
5. Run to see error

Expected behavior (REQUIRED)
Build should complete without errors.

Defold version (REQUIRED):

• Version 1.8.0 (9141d9d)
• Version 1.7.0 (bf4dc66)

Platforms (REQUIRED):

• Platforms: HTML5
• OS: Linux Alpine (Eclipse Temurin with OpenJDK 17)

Note that "Bob cannot find oggz-validate on Linux" isn't strictly true.
The error says "Cannot run program".

I can see a few common reasons:

• A missing dependency
• The wrong architecture for the OS

Q: What architecture does your runner use? x86_64 or arm64 ?

Q: What if you output the dependencies for the executable on that machine?

I.e. unpack the bob.jar file, and run ldd on the oggz-validate tool.
On my local docker (Ubuntu), it looks like this:

builder@ubuntu:~$ ldd ./com.dynamo.cr/com.dynamo.cr.bob/libexec/x86_64-linux/oggz-validate
	linux-vdso.so.1 (0x00007fff36be0000)
	liboggz.so => /home/builder/./com.dynamo.cr/com.dynamo.cr.bob/libexec/x86_64-linux/liboggz.so (0x00007f65c6c93000)

x86_64. GitLab refers to them as amd64 though if that makes any difference.

Q: What if you output the dependencies for the executable on that machine?

$ ldd ./bob/libexec/x86_64-linux/oggz-validate

Should I edit the title?

So indeed this was an issue in the environment rather than bob. After installing the required dependencies missing from Alpine (apk add gcompat in this case) the build completes successfully again.
