the build fails with glib 2.29.92-0ubuntu1 gcc-4.6 4.6.1-9ubuntu3 and binutils 2.21.53.20110810-0ubuntu3 with flto applied to compilation and linking stage: dpkg-buildpackage config APPEND CFLAGS -flto APPEND LDFLAGS -flto
See the attached buildlog It succeeds without -flto. When building with -U_FORTIFY_SOURCE the linking failure is solved but one gets this error: gcc -DHAVE_CONFIG_H -I. -I/tmp/glib2.0-2.29.92/./glib/tests -I../.. -g -I../.. -I../../glib -I/tmp/glib2.0-2.29.92/./glib -I/tmp/glib2.0-2.29.92/. -DSRCDIR=\""/tmp/glib2.0-2.29.92/./glib/tests"\" -DG_ENABLE_DEBUG -DG_DISABLE_SINGLE_INCLUDES -pthread -g -O2 -flto -U_FORTIFY_SOURCE -Wall -c /tmp/glib2.0-2.29.92/./glib/tests/mem-overflow.c /tmp/glib2.0-2.29.92/./glib/tests/mem-overflow.c:137:1: sorry, unimplemented: gimple bytecode streams do not support the optimization attribute ** Attachment added: "-flto added to default flags" https://bugs.launchpad.net/ubuntu/+source/binutils/+bug/856839/+attachment/2443193/+files/glib-default%2Blto.buildlog -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/856839 Title: libglib2.0-0 fails to build using dpkg-buildpackage when added "-flto" to CFLAGS and LDFLAGS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/binutils/+bug/856839/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
