fdpp configure fails without thunk_gen

[taviso]

I was following the instructions on the wiki to build dosemu from source and got this meson error when configuring fdpp:

subprojects/libfdpp/meson.build:132:5: ERROR: custom_target keyword argument 'depends' was of type array[LocalProgram] but should have been array[BuildTarget | CustomTarget | CustomTargetIndex]

I think it's trying to tell me that I need to install thunk_gen, but I didn't because the docs said:

fdpp also requires thunk-gen, but if you still haven't installed it, don't worry

So I guess this error is unexpected?

$ meson --version
1.11.1

mesonbuild/meson#15774
This seems to be a regression in 1.11.

[stsp]

They targeted the solution to 1.11.3,
which hell knows when will be released.
Given that the fix is already over 2
months in their git, I'd say this is a
big breach of trust from their side.
Probably sufficient enough to think
about dropping meson completely.

For now you need to use meson-1.10.

Thanks for investigating! It is weird they'd just break builds and not seem to worry about it too much, but oh well. I think I can downgrade for now.

[taviso]

Apparently recent fontconfig requires meson >=1.11.0, everything else seems to be fine with a downgrade to 1.10.x.

[stsp]

You mean you re-build everything?
Generally fontconfig is pre-instelled,
so who cares what it needs?

[taviso]

I'm using gentoo, so updates require build dependencies. I can downgrade and pin easily emerge =dev-build/meson-1.10*, but that broke updates by creating unsolvable dependencies.

It's no problem, just an annoyance.

[stsp]

Of course you can still install
thunk-gen externally and build
fdpp with plain make...

[stsp]

Update: they targeted the solution
towards 1.11.3 AND 1.12, so we are
not in an unfixable situation. 1.12
will come before 1.11.3.

[stsp]

meson-1.12 released.
