- Subject: [patch 1/2] Make gdbtui a shell script
Hi,
it is discussed for years it is not great to have almost the same gdb and
gdbtui binaries, each ~5MB. Make gdbtui a shell script.
I am not so sure how well is the shell script portable across Unices.
I assume MinGW is out of question anyway but that may not be a concern.
Fedora has been using gdb<->gdbtui hardlink but according to Tom argv[0]
should not be used. GNU Coding Standards IMO do not say exactly this thing.
Thanks,
Jan

Replace gdbtui binary by a shell script.
* Makefile.in (INSTALL_SCRIPT): New variable.
(SUBDIR_TUI_OBS): Remove tui-main.o.
(SUBDIR_TUI_SRCS): Remove tui/tui-main.c.
(all-tui): Remove its $(TUI)$(EXEEXT) dependency.
(install-tui): Change INSTALL_PROGRAM to INSTALL_SCRIPT, add .sh to
source $(TUI) and remove $(EXEEXT) from the target.
(uninstall-tui): Remove $(EXEEXT) from the target.
($(TUI)$(EXEEXT)): Remove.
(clean-tui): Remove its only recipe.
(tui-main.o): Remove.
(all_object_files): Remove tui-main.o.
* gdbtui.sh: New file.
* tui/tui-main.c: Remove.
