The patch controls the configure variab1e "development". Looking at the configure.ac script, I found that the selftest tests are only activated when it is set: if $development; then AC_DEFINE(GDB_SELF_TEST, 1, [Define if self-testing features should be enabled]) CONFIG_OBS="$CONFIG_OBS \$(SUBDIR_UNITTESTS_OBS)" CONFIG_SRCS="$CONFIG_SRCS \$(SUBDIR_UNITTESTS_SRCS)" fi I assume the error is related to the above, since it's a link failure related to selftests... | [...] | ../readline/libreadline.a ../opcodes/libopcodes.a ../bfd/libbfd.a -L./../zlib -lz ../libiberty/libiberty.a ../libdecnumber/libdecnumber.a -ldl -ldl -lncursesw -lm -ldl -lguile-2.0 -lgc -lpthread -ldl -lutil -lm -lpython2.7 -lexpat -llzma -lbabeltrace -lbabeltrace-ctf -lipt ../libiberty/libiberty.a build-gnulib/import/libgnu.a -ldl -Wl,--dynamic-list=../../binutils-gdb/gdb/proc-service.list | selftest.o: In function `selftests::run_tests(char const*)': | /home/gdb-buildbot-2/fedora-x86-64-4/fedora-x86-64/build/gdb/../../binutils-gdb/gdb/common/selftest.c:97: undefined reference to `selftests::reset()' | collect2: error: ld returned 1 exit status I think re-starting the build from scratch will make the problem disappear. -- Joel
