meson bug with vala #10517

Open nda-cunh opened 2 years ago

nda-cunh commented 2 years ago

hello, i found a bug in meson.build with vala.

image

when i give the name of a function in glade then it can call it. the problem is that it gives me the following error in vala with meson. image however it is in my code: image

Whereas if I compile my vala file manually (valac main.vala --pkg=gtk4) then run it it works. why with meson I have the error?

dcbaker commented 2 years ago

What does your Meson build look like?

nda-cunh commented 2 years ago

its a simple meson.build :+1: 

project('calculatrice', ['vala', 'c'])

vala_dep = [dependency('gtk4'), dependency('glib-2.0'), dependency('gobject-2.0')]

executable('calculatrice',
           'main.vala',
           dependencies : vala_dep,
           install : true)

and my command compilation is just : valac main.vala --pkg=gtk4

@hydrasho could you provide a symbol dump of your executable? You can use nm

tristan957 commented 2 years ago

Do you not need to annotate your Vala function with [GtkCallback]?

nda-cunh commented 2 years ago

He dont work when i add [GtkCallback] in my code :/

tristan957 commented 2 years ago

@eli-schwartz didn't you recently make a change regarding the default value of gnu_symbol_visibility? Would that have affected this?

@hydrasho please provide a symbol dump using readelf --syms <my binary>

dcbaker commented 2 years ago

Wait, this is an undefined symbol issue, we’re probably injecting a command line option to make that happen. What is the command line for vala in the ninja.build file?

put_zero is not in the .dynsym section in the Meson buidl. Not obvious to me what this means.

nda-cunh commented 2 years ago

I don't want to make a Makefile just for that :/

tristan957 commented 2 years ago

Can you try configuring -Dc_args="-Wl,--export-dynamic"

dcbaker commented 2 years ago

Executable also has an export_dynamic keyword argument

nda-cunh commented 2 years ago

with: add_project_arguments(['-Dc_args="-Wl,--export-dynamic"'], language: 'c') still not working

dcbaker commented 2 years ago

that should be either add_project_link_args('-export-dynamic', language : c'), or:

executable('calculatrice',
           'main.vala',
           dependencies : vala_dep,
           export_dynamic : true,
           install : true)
dcbaker commented 2 years ago

I recomend the second, as Meson will just Do The Right Thing™

nda-cunh commented 2 years ago

it works now the functions are no longer ignored! thank you

tristan957 commented 2 years ago

So what is the solution on Meson's part here? Seemingly this used to work and now it doesn't unless you set export_dynamic.
