Failed to install in ruby docker image (vm_insnhelper.h missing)

[Adrian Marin]

Hi.

I'm getting the following error and don't know how to solve it. Can you please help me with this?

Context

I'm trying to install this in a docker image that starts from ruby:3.2.1 (tried 3.2.0 and 3.1.0).
I clone the repository, I build the gem and then try to install it.

RUN git clone --branch v0.2.5.beta2 https://github.com/ruby-debug/debase.git
RUN cd debase && gem build
RUN gem install debase ./debase/debase-0.2.5.beta2.gem

I see that vm_insnhelper.h is missing.

Seems like this may be solved with the solution mentioned in #102

I can confirm that 0.2.5.beta2 did not fix my issue.
I tried to install it from rubygems and from github from the 0.2.5.beta2 specific branch.

The error is different from #102
