Created attachment 346678 [details] gucharmap-3.6.1-vala-version-fix.patch Relevant config.log entry: ---- configure:14372: $PKG_CONFIG --exists --print-errors "$vapigen_pkg" Package vapigen-0.18 was not found in the pkg-config search path. Perhaps you should add the directory containing `vapigen-0.18.pc' to the PKG_CONFIG_PATH environment variable No package 'vapigen-0.18' found configure:14375: $? = 1 configure:14389: error: vapigen-0.18 >= 0.16 not found ---- Latest unstable for vala is 0.20, so without setting the max version and vala-0.18 not being installed the package will not compile. The attached ebuild patch fixes this issue.
I have hit same issue after I left only vala-0.20 in the system and confirm that gucharmap-3.6.1 will not build without vala-0.18 package
You shouldn't mix stable and testing. If you want to do that, you need to run testing versions of more packages. In this case, you need latest gucharmap to work with latest vala -> gucharmap-3.8 has vala-0.20 support
