--- Comment #10 from Alan Griffiths <alan at octopull dot co.uk> --- It took me some time and effort to reproduce too. :( Building in my normal development environments showed no problems. And I've yet to reproduce on Ubuntu (although the builders we use fail building for 17.10). The steps I took (on Fedora 27): $ sudo dnf install mock $ sudo usermod -a -G mock $USER $ wget https://copr-be.cloud.fedoraproject.org/results/ngompa/mir-prerel-fedora/fedora-27-x86_64/00685833-mir/mir-0.29~git20171208.1.5500595-0.fc27.1.src.rpm $ mock -r fedora-27-x86_64 mir-0.29~git20171208.1.5500595-0.fc27.1.src.rpm $ mock -r fedora-27-x86_64 --shell # cd /builddir/build/BUILD/mir-5500595810c28c150a3bd9edf19b392c2aeab932/x86_64-redhat-linux-gnu/src/server/frontend/wayland && /usr/bin/c++ -DLOG_NDEBUG=1 -DMESA_EGL_NO_X11_HEADERS -DMIR_DRMMODEADDFB_HAS_CONST_SIGNATURE -DMIR_LOG_COMPONENT_FALLBACK=\"mirserver\" -DMIR_SERVER_EGL_OPENGL_API=EGL_OPENGL_ES_API -DMIR_SERVER_EGL_OPENGL_BIT=EGL_OPENGL_ES2_BIT -DMIR_SERVER_GLEXT_H="<GLES2/gl2ext.h>" -DMIR_SERVER_GL_H="<GLES2/gl2.h>" -DMIR_SERVER_GRAPHICS_PLATFORM_VERSION=\"MIR_GRAPHICS_PLATFORM_0.27\" -DMIR_SERVER_INPUT_PLATFORM_VERSION=\"MIR_INPUT_PLATFORM_0.27\" -DMIR_SERVER_PLATFORM_PATH=\"/usr/lib64/mir/server-platform\" -DMIR_VERSION=\"0.29.0\" -DMIR_VERSION_MAJOR=0 -DMIR_VERSION_MICRO=0 -DMIR_VERSION_MINOR=29 -D_FILE_OFFSET_BITS=64 -D_GNU_SOURCE -I/builddir/build/BUILD/mir-5500595810c28c150a3bd9edf19b392c2aeab932/include/core -I/builddir/build/BUILD/mir-5500595810c28c150a3bd9edf19b392c2aeab932/include/common -I/builddir/build/BUILD/mir-5500595810c28c150a3bd9edf19b392c2aeab932/include/cookie -I/builddir/build/BUILD/mir-5500595810c28c150a3bd9edf19b392c2aeab932/src/include/common -I/builddir/build/BUILD/mir-5500595810c28c150a3bd9edf19b392c2aeab932/x86_64-redhat-linux-gnu/src/capnproto -I/builddir/build/BUILD/mir-5500595810c28c150a3bd9edf19b392c2aeab932/x86_64-redhat-linux-gnu/src/protobuf -I/builddir/build/BUILD/mir-5500595810c28c150a3bd9edf19b392c2aeab932/include/platform -I/builddir/build/BUILD/mir-5500595810c28c150a3bd9edf19b392c2aeab932/include/client -I/builddir/build/BUILD/mir-5500595810c28c150a3bd9edf19b392c2aeab932/include/server -I/builddir/build/BUILD/mir-5500595810c28c150a3bd9edf19b392c2aeab932/include/renderer -I/builddir/build/BUILD/mir-5500595810c28c150a3bd9edf19b392c2aeab932/include/renderers/gl -I/builddir/build/BUILD/mir-5500595810c28c150a3bd9edf19b392c2aeab932/include/renderers/sw -I/builddir/build/BUILD/mir-5500595810c28c150a3bd9edf19b392c2aeab932/src/include/platform -I/builddir/build/BUILD/mir-5500595810c28c150a3bd9edf19b392c2aeab932/src/include/client -I/builddir/build/BUILD/mir-5500595810c28c150a3bd9edf19b392c2aeab932/src/include/server -I/builddir/build/BUILD/mir-5500595810c28c150a3bd9edf19b392c2aeab932/src/include/cookie -I/usr/include/glib-2.0 -I/usr/lib64/glib-2.0/include -O2 -g -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -m64 -mtune=generic -pthread -g -std=c++14 -Werror -Wall -fno-strict-aliasing -pedantic -Wnon-virtual-dtor -Wextra -fPIC -Wno-psabi -flto -ffat-lto-objects -o CMakeFiles/mirfrontend-wayland.dir/wayland_connector.cpp.o -c /builddir/build/BUILD/mir-5500595810c28c150a3bd9edf19b392c2aeab932/src/server/frontend/wayland/wayland_connector.cpp
