From: Simon Marchi Date: Thu, 12 Mar 2020 18:18:00 +0000 (-0400) Subject: Move sourcing of development.sh to GDB_AC_COMMON X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=db6878ac5538661c8d66c916a533bd4268217fcb;p=binutils-gdb.git Move sourcing of development.sh to GDB_AC_COMMON The same is done for gdb, gdbserver and gdbsupport. I therefore think it makes sense to move that to GDB_AC_COMMON. It is required to move the call to GDB_AC_COMMON so it is before GDB_AC_SELFTEST in gdbserver/configure.ac, otherwise the $development variable isn't set when the code behind GDB_AC_SELFTEST executes. gdb/ChangeLog: * configure.ac: Don't source bfd/development.sh. * selftest.m4: Modify comment. * configure: Re-generate. gdbserver/ChangeLog: * configure.ac: Don't source bfd/development.sh, move GDB_AC_COMMON higher. * configure: Re-generate. gdbsupport/ChangeLog: * configure.ac: Don't source bfd/development.sh. * common.m4: Source bfd/development.sh. * configure: Re-generate. --- diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 490d9cbae5c..eef1e6492ce 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,9 @@ +2020-03-12 Simon Marchi + + * configure.ac: Don't source bfd/development.sh. + * selftest.m4: Modify comment. + * configure: Re-generate. + 2020-03-12 Simon Marchi * selftest.m4 (GDB_AC_SELFTEST): Error out if $development is diff --git a/gdb/configure b/gdb/configure index dd34688687e..f690cf86078 100755 --- a/gdb/configure +++ b/gdb/configure @@ -2988,9 +2988,6 @@ fi -# Set the 'development' global. -. $srcdir/../bfd/development.sh - ac_ext=c ac_cpp='$CPP $CPPFLAGS' ac_compile='$CC -c $CFLAGS $CPPFLAGS conftest.$ac_ext >&5' @@ -12434,6 +12431,9 @@ $as_echo "$ac_cv_path_SED" >&6; } rm -f conftest.sed + # Set the 'development' global. + . $srcdir/../bfd/development.sh + { $as_echo "$as_me:${as_lineno-$LINENO}: checking for ANSI C header files" >&5 $as_echo_n "checking for ANSI C header files...
