Could not find GIR file 'Folks-0.6.gir'
folks 0.15.1 fails to build with the error:
Could not find GIR file 'Folks-0.6.gir'; check XDG_DATA_DIRS or use --includedirerror parsing file R:/winlibs64-9.2.0/folks-0.15.1/build_both/backends/dummy/lib/FolksDummy-0.7.gir: Failed to parse included gir Folks-0.6
Solution:
After changing 0.6 to 0.7 on the line specifying the Folks version (<include name="Folks" version="0.6"/>
) in file backends/dummy/lib/FolksDummy-0.7.gir generated by meson. So the real solution is to fix the version in the source this file is generated from.
