commit 6ba7ae5 works:

❯ git checkout 6ba7ae5
Note: switching to '6ba7ae5'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

HEAD is now at 6ba7ae5 Add missing "b.le" on arm

Radare2 version 5.8.9 (although, looking at the latest r2dec commits, I don't think it matters)

❯ radare2 -v
radare2 5.8.9 31530 @ linux-x86-64
birth: git.5.8.8-888-g4ceb8ebba3 2023-11-23__19:36:13

options: gpl -O? cs:5 cl:2 make

[wargio]

yes ofc. @trufae you should use tags not master as is, unless you update it to use meson and the new folder structure.

[trufae]

I updated the package and it should work. Did you updated the database?

[wargio]

@dguerri please confirm this is fixed and close the issue :)

[trufae]

r2pm -Uci r2dec

-U updates the database There’s also r2dec-duk which picks then last commit that used duktape. The default pkg uses master

[dguerri]

It seems to be failing silently as b doesn't contain a valid build tree:

[dguerri]

This worked:

cd /root/.local/share/radare2/r2pm/git/r2dec
meson . b
ninja install

[dguerri]

I think it's somehow trying to use the old build "system" with meson and ninja instead of make

[trufae]

works fine here

i added an rm -rf b at the begining to force meson rebuild the directory. it should work well for you too. thanks for reporting

[dguerri]

Weird! Could it be the meson version?

I will look into it as soon I am back home.

[dguerri]

I am still seeing the above issue on a vanilla Ubuntu 22.04.3. Meson version 0.61.2

I see you are using MacOS, and the version of meson shipped with homebrew is 1.3.0:

❯ brew info meson
==> meson: stable 1.3.0 (bottled), HEAD

Maybe a safe option could be to wipe b and then use

meson . b

Instead of

meson b --reconfigure

[trufae]

try again, i removed the --reconfigure flag
