We don't build GDB selftests bits when $development is false. However, if we turn bfd/development.sh:$development to false, common/selftest.c is compiled which is not expected. It causes the build failure, selftest.o: In function `selftests::run_tests(char const*)': binutils-gdb/gdb/common/selftest.c:97: undefined reference to `selftests::reset()' collect2: error: ld returned 1 exit status I fix this issue by putting selftest.o selftest-arch.o into CONFIG_OBS only when $development is true. After this is fixed, there are other build failures in maint.c, this patch fixes them as well. In the release mode, the output of these commands are: (gdb) maintenance selftest Selftests are not available in a non-development build. (gdb) maintenance selftest foo Selftests are not available in a non-development build. (gdb) maintenance info selftests Selftests are not available in a non-development build. gdb: 2018-01-08 Yao Qi <yao.qi@linaro.org> Simon Marchi <simon.marchi@ericsson.com> * Makefile.in (COMMON_SFILES): Remove selftest-arch.c and common/selftest.c. (COMMON_OBS): Remove selftest.o. * configure.ac: Append selftest-arch.c and common/selftest.c to CONFIG_SRCS. Append selftest-arch.o and selftest.o to COMMON_OBS. * configure: Re-generated. * maint.c (maintenance_selftest): Wrap selftests::run_tests with GDB_SELF_TEST. (maintenance_info_selftests): Likewise. gdb/testsuite: 2018-01-08 Simon Marchi <simon.marchi@ericsson.com> * gdb.gdb/unittest.exp: Match output in non-development mode.
