Does not work on Ubuntu 20.10, with ruby 2.7.1p83

I'm sure I've followed instructions.
Issue with Stable and Unstable, and I can't see what problem is.

@jradxl Although I'm not a C programmer, I've recently experienced what I believe is the same problem, on another project.

In that case, the problem was the switch from GCC 9 to 10 (Ubuntu 20.04 ships GCC 9.3; 2010 ships GCC 10.2), which disables the so-called "common model".

If the problem is the same, either the flag -fcommon will fix the problem, or propertly declaring the variable. I'll take a look.

Yes, this is the problem: https://bugs.gentoo.org/705898

[64kramsystem]

@jradxl Can you try to build from my fork/branch, and see if it works (I can't test immediately)? If it does, I'll open a PR.

Repository: https://github.com/saveriomiroddi/ruby-packer-dev.git
Branch: sav/make_gcc_10_compatible

[64kramsystem]

@jradxl Can you rename the title to something like The project fails to compile on GCC 10? It describes the issue precisely.

[jradxl]

Hello, thanks @saveriomiroddi , but alas, I can't get a build of your branch or the main branch.
My failure shown below. This does show on a Google search, but
https://github.com/ruby/ruby/commit/47720e2255f34ecad49763c66a7ea02a55a3f60a
does not fix.
I have bison -V
bison (GNU Bison) 3.7

I may have a missing dependency. I'll keep looking.

@jradxl I think that it's the issue you've likely read (https://bugs.ruby-lang.org/issues/17106), and on my system, where the compilation fails, my Bison version is indeed older (3.5.1).

Note that in the issue, they mention that a certain commit (b971bad49b) fixes is on 2.7, however, I've checked the Ruby repo history, and it's included in Ruby 2.7.2. Try with that!

Any resolution to this?

Hello!

Based on your error log, it seems to be different from the other two problems in this issue. The log posted actually doesn't have much information about the exact error.

[temporarium]

It's almost identical output to the first post. What else can I provide you to get past this? Is my Ruby version too recent? I don´t know where to go from here :-(
