When $development is unset, GDB_AC_SELFTEST defaults to enabling selftests. I don't think the macro was written with this intention in mind, it just happens to be that way. So gdbsupport thinks selftests are enabled, while gdb thinks they are disabled. gdbsupport compiles in code that calls selftests:: functions, which are normally provided by gdb, but gdb doesn't provide them, hence the undefined references. Fix this by sourcing bfd/development.sh in gdbsupport/configure.ac, so that the development variable is set. gdbsupport/ChangeLog: * configure.ac: Added call development.sh. * configure: Regenerate. --- diff --git a/gdbsupport/ChangeLog b/gdbsupport/ChangeLog index c47bb4ebbba..6bfd6768727 100644 --- a/gdbsupport/ChangeLog +++ b/gdbsupport/ChangeLog @@ -1,3 +1,8 @@ +2020-03-05 Vyacheslav Petrishchev + + * configure.ac: Added call development.sh. + * configure: Regenerate. + 2020-03-05 Tankut Baris Aktemur * .gitattributes: New file. diff --git a/gdbsupport/configure b/gdbsupport/configure index a4871f8d5bc..e7a99e3ddfb 100755 --- a/gdbsupport/configure +++ b/gdbsupport/configure @@ -6569,6 +6569,9 @@ fi am_cv_prog_cc_stdc=$ac_cv_prog_cc_stdc +# Set the 'development' global. +. $srcdir/../bfd/development.sh + # We require a C++11 compiler.
