Hello!
I am trying to bind to libfuse from a Vala program. I see that in
libfuse
I must specify a define to the version of the API I want to
use[4]. I read
the Vala documentation as to how to define a symbol[3]. I see that
there
is documentation in meson for how to add arguments to valac[1] but
when I
set my flag, add_project_arguments('-D FUSE_USE_VERSION=26',
language:
Try to split the arguments in two or remove the space between '-D' and 'FUSE_USE_VERSION=26'. Like mentioned elsewhere, you will have to set language: 'c' for this case to work.
'vala'), valac complains that it doesn't recognize the option and in the build output panel in Gnome Builder it appears to wrap the expression in single quotes. When run valac directly from the command line and sidestep meson, it seems that the define is ignored[2]. As a sanity test, if I modify the header to define the value, I get the behavior I want. My question is, how can I set a preprocessor symbol to a specific value via Meson or valac?
