I had the same issue. I'm assuming a regression in Meson, but I haven't checked.

With colord, packagekit, and webp installed, Meson is building invalid args for the main build step, which prevents the project from building. The build declaration (meson.build) generates a Python list of vala_args. The list of args looks OK getting passed into executable(). However, the auto-generated build.ninja is missing the required -D(efine) flags. As a result, it treats some of defines as filenames, and crashes. Vala/Meson/Ninja are new to me, so I'm not sure if the problem is with the build file, or the Meson generator, or what. # ./src/meson.build # If all three packages are installed, they're built into the Python list. Somehow, the -D flags disappear during build generation vala_args = [ '--pkg=posix', '--vapidir=' + meson.current_source_dir () ] dependencies = [ glib_dep, gtk_dep, zlib_dep, cairo_dep, gdk_pixbuf_dep, gusb_dep, sane_dep ] if colord_dep.found () vala_args += [ '-D', 'HAVE_COLORD' ] dependencies += colord_dep endif if packagekit_dep.found () vala_args += [ '-D', 'HAVE_PACKAGEKIT' ] dependencies += packagekit_dep endif if webp_dep.found () and (not colord_dep.found () or webpmux_dep.found ()) # Webpmux only required if colord vala_args += [ '-D', 'HAVE_WEBP' ] dependencies += [ webp_dep, webpmux_dep ] endif simple_scan = executable ('simple-scan', [ 'config.vapi', 'app-window.vala', 'authorize-dialog.vala', 'book.vala', 'book-view.vala', 'page.vala', 'page-view.vala', 'preferences-dialog.vala', 'simple-scan.vala', 'scanner.vala', 'screensaver.vala', 'autosave-manager.vala' ] + resources, dependencies: dependencies, vala_args: vala_args, c_args: [ '-DVERSION="@0@"'.format (meson.project_version ()), '-DGETTEXT_PACKAGE="simple-scan"', '-DLOCALE_DIR="@0@"'.format (localedir), '-DICON_DIR="@0@"'.format (icondir), '-DI_KNOW_THE_PACKAGEKIT_GLIB2_API_IS_SUBJECT_TO_CHANGE' ], link_args: [ '-lm' ], install: true ) # ./build/build.ninja # Snippet of the bad build step.
