annotate libinterp/parse-tree/pt-id.cc @ 15195:2fc554ffbc28
split libinterp from src
* libinterp: New directory. Move all files from src directory here
except Makefile.am, main.cc, main-cli.cc, mkoctfile.in.cc,
mkoctfilr.in.sh, octave-config.in.cc, octave-config.in.sh.
* libinterp/Makefile.am: New file, extracted from src/Makefile.am.
* src/Makefile.am: Delete everything except targets and definitions
needed to build and link main and utility programs.
* Makefile.am (SUBDIRS): Include libinterp in the list.
* autogen.sh: Run config-module.sh in libinterp/dldfcn directory, not
src/dldfcn directory.
* configure.ac (AC_CONFIG_SRCDIR): Use libinterp/octave.cc, not
src/octave.cc.
(DL_LDFLAGS, LIBOCTINTERP): Use libinterp, not src.
(AC_CONFIG_FILES): Include libinterp/Makefile in the list.
* find-docstring-files.sh: Look in libinterp, not src.
* gui/src/Makefile.am (liboctgui_la_CPPFLAGS): Find header files in
libinterp, not src.
