From 4627b5df69fac65e35429b3f876748a59c1bb47a Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Thu, 9 Apr 2020 09:41:16 +0200 Subject: [PATCH] build: move symvers files to kernel build dir The symvers files of older kernel versions are incompatible with the ones from 5.4, so changing the kernel version without running make clean was causing build failures in kernel module packages. Fix this by moving the directory, ensuring that symvers files get thrown away with a kernel version change Signed-off-by: Felix Fietkau --- include/kernel.mk | 10 ++++++---- 1 file changed, 6 insertions(+), 4 deletions(-) diff --git a/include/kernel.mk b/include/kernel.mk index 02d0949a7210..40aa1a5163e9 100644 --- a/include/kernel.mk +++ b/include/kernel.mk @@ -138,11 +138,13 @@ endif PKG_EXTMOD_SUBDIRS ?= . +PKG_SYMVERS_DIR = $(KERNEL_BUILD_DIR)/symvers + define populate_module_symvers - @mkdir -p $(PKG_INFO_DIR) - cat /dev/null > $(PKG_INFO_DIR)/$(PKG_NAME).symvers; \ + @mkdir -p $(PKG_SYMVERS_DIR) + cat /dev/null > $(PKG_SYMVERS_DIR)/$(PKG_NAME).symvers; \ for subdir in $(PKG_EXTMOD_SUBDIRS); do \ - cat $(PKG_INFO_DIR)/*.symvers 2>/dev/null > $(PKG_BUILD_DIR)/$$$$subdir/Module.symvers; \ + cat $(PKG_SYMVERS_DIR)/*.symvers 2>/dev/null > $(PKG_BUILD_DIR)/$$$$subdir/Module.symvers; \ done endef @@ -154,7 +156,7 @@ define collect_module_symvers grep -F $$$$realdir $(PKG_BUILD_DIR)/$$$$subdir/Module.symvers >> $(PKG_BUILD_DIR)/Module.symvers.tmp; \ done; \ sort -u $(PKG_BUILD_DIR)/Module.symvers.tmp > $(PKG_BUILD_DIR)/Module.symvers; \ - mv $(PKG_BUILD_DIR)/Module.symvers $(PKG_INFO_DIR)/$(PKG_NAME).symvers + mv $(PKG_BUILD_DIR)/Module.symvers $(PKG_SYMVERS_DIR)/$(PKG_NAME).symvers endef define KernelPackage/hooks -- 2.30.2
