From e0b250b57dcf403529081e5898a9de717f96b76b Mon Sep 17 00:00:00 2001 From: Jonas Zeiger Date: Wed, 3 Jun 2020 15:34:05 +0200 Subject: Makefile: install modules.builtin even if CONFIG_MODULES=n Many applications check for available kernel features via: - /proc/modules (loaded modules, present if CONFIG_MODULES=y) - $(MODLIB)/modules.builtin (builtin modules) They fail to detect features if the kernel was built with CONFIG_MODULES=n and modules.builtin isn't installed. Therefore, add the target "_builtin_inst_" and make "install" and "modules_install" depend on it. Tests results: - make install: kernel image is copied as before, modules.builtin copied - make modules_install: (CONFIG_MODULES=n) nothing is copied, exit 1 Signed-off-by: Jonas Zeiger Signed-off-by: Masahiro Yamada --- Makefile | 14 +++++++++++--- 1 file changed, 11 insertions(+), 3 deletions(-) (limited to 'Makefile') diff --git a/Makefile b/Makefile index ee3ed9dfca2c..7b750dc0b2da 100644 --- a/Makefile +++ b/Makefile @@ -1322,6 +1322,16 @@ dt_binding_check: scripts_dtc # --------------------------------------------------------------------------- # Modules +# install modules.builtin regardless of CONFIG_MODULES +PHONY += _builtin_inst_ +_builtin_inst_: + @mkdir -p $(MODLIB)/ + @cp -f modules.builtin $(MODLIB)/ + @cp -f $(objtree)/modules.builtin.modinfo $(MODLIB)/ + +PHONY += install +install: _builtin_inst_ + ifdef CONFIG_MODULES # By default, build modules as well @@ -1365,7 +1375,7 @@ PHONY += modules_install modules_install: _modinst_ _modinst_post PHONY += _modinst_ -_modinst_: +_modinst_: _builtin_inst_ @rm -rf $(MODLIB)/kernel @rm -f $(MODLIB)/source @mkdir -p $(MODLIB)/kernel @@ -1375,8 +1385,6 @@ _modinst_: ln -s $(CURDIR) $(MODLIB)/build ; \ fi @sed 's:^:kernel/:' modules.order > $(MODLIB)/modules.order - @cp -f modules.builtin $(MODLIB)/ - @cp -f $(objtree)/modules.builtin.modinfo $(MODLIB)/ $(Q)$(MAKE) -f $(srctree)/scripts/Makefile.modinst # This depmod is only for convenience to give the initial -- cgit v1.2.3-58-ga151
