The cmake configuration looks for a native xdg-dbus-proxy executable, so building webkit-gtk in a sysroot fails because it's not installed via BDEPEND. Reproducible: Always Steps to Reproduce: 1. emerge --rage-clean xdg-dbus-proxy 2. cross-emerge -v webkit-gtk Actual Results: CMake Error at Source/cmake/BubblewrapSandboxChecks.cmake:14 (message): xdg-dbus-proxy not found and is needed for ENABLE_BUBBLEWRAP_SANDBOX Call Stack (most recent call first): Source/cmake/OptionsGTK.cmake:491 (include) Source/cmake/WebKitCommon.cmake:58 (include) CMakeLists.txt:173 (include) Expected Results: It should build and install. Looking at the build system, the only actual usage of xdg-dbus-proxy seems to be path substitution in Source/WebKit/UIProcess/Launcher/glib/BubblewrapLauncher.cpp to call it at runtime, so it doesn't actually call the native program (i.e. it's correct in RDEPEND). It could therefore be fixed by adding -DDBUS_PROXY_EXECUTABLE:FILEPATH=${EPREFIX}/usr/bin/xdg-dbus-proxy to cmake args (like it's already doing with -DBWRAP_EXECUTABLE) to work around the bad cmake test, as opposed to adding it to BDEPEND and needlessly compiling a native version. I just verified it works with the MYCMAKEARGS environment variable. This is probably the expected way to fix since it prints this warning when cross-compiling: ***--------------------------------------------------------*** *** Cannot check Bubblewrap version when cross-compiling. *** *** The target system MUST have version 0.3.1 or newer. *** *** Use the BWRAP_EXECUTABLE and DBUS_PROXY_EXECUTABLE *** *** variables to set the run-time paths for the 'bwrap' *** *** and 'xdg-dbus-proxy' programs. *** ***--------------------------------------------------------***

Keep passing -DNDEBUG for the time being again. * Improve cross-compilation by not requiring sys-apps/xdg-dbus-proxy on CBUILD * Build the MiniBrowser with USE=examples Bug: https://bugs.gentoo.org/761238 Closes: https://bugs.gentoo.org/760902 Closes: https://bugs.gentoo.org/758299 Package-Manager: Portage-3.0.12, Repoman-3.0.2 Signed-off-by: Mart Raudsepp <leio@gentoo.org> net-libs/webkit-gtk/metadata.xml | 1 + net-libs/webkit-gtk/webkit-gtk-2.30.4-r1.ebuild | 300 ++++++++++++++++++++++++ 2 files changed, 301 insertions(+)
