From 7e736938985f72f01467d2d48c13adb74e9bda32 Mon Sep 17 00:00:00 2001 From: Angus Gratton Date: Tue, 8 Sep 2015 09:59:59 +1000 Subject: [PATCH] Rework component makefiles to have a default _ROOT This fixes a long-standing bug where build directories sometimes expanded many levels deeper than they should have. Component names can now no longer contains slashes (ie the component name for 'extras/i2c' is now just 'i2c') --- FreeRTOS/component.mk | 3 +-- axtls/component.mk | 7 +++---- common.mk | 3 +++ core/component.mk | 2 +- extras/bmp180/component.mk | 8 ++++---- extras/i2c/component.mk | 9 +++++---- extras/rboot-ota/component.mk | 8 ++++---- lwip/component.mk | 7 +++---- 8 files changed, 24 insertions(+), 23 deletions(-) diff --git a/FreeRTOS/component.mk b/FreeRTOS/component.mk index 437fccb..4b63b73 100644 --- a/FreeRTOS/component.mk +++ b/FreeRTOS/component.mk @@ -1,8 +1,7 @@ -INC_DIRS += $(freertos_MAIN)/include $(freertos_MAIN)/portable/esp8266 +INC_DIRS += $(freertos_MAIN)include $(freertos_MAIN)portable/esp8266 # args for passing into compile rule generation -freertos_ROOT = $(ROOT)FreeRTOS/ freertos_MAIN = $(freertos_ROOT)Source/ freertos_INC_DIR = $(freertos_MAIN)include $(freertos_MAIN)portable/esp8266 freertos_SRC_DIR = $(freertos_MAIN) $(freertos_MAIN)portable/esp8266 diff --git a/axtls/component.mk b/axtls/component.mk index 44da5a0..73859a2 100644 --- a/axtls/component.mk +++ b/axtls/component.mk @@ -6,13 +6,12 @@ # We supply our own hand tweaked config.h in the external 'include' dir. -AXTLS_DIR = $(ROOT)axtls/axtls/ -INC_DIRS += $(ROOT)axtls/include $(AXTLS_DIR)ssl $(AXTLS_DIR)crypto +AXTLS_DIR = $(axtls_ROOT)axtls/ +INC_DIRS += $(axtls_ROOT)include $(AXTLS_DIR)ssl $(AXTLS_DIR)crypto # args for passing into compile rule generation -axtls_ROOT = $(ROOT)axtls axtls_INC_DIR = $(AXTLS_DIR)include $(AXTLS_DIR) -axtls_SRC_DIR = $(AXTLS_DIR)crypto $(AXTLS_DIR)ssl $(ROOT)axtls +axtls_SRC_DIR = $(AXTLS_DIR)crypto $(AXTLS_DIR)ssl $(axtls_ROOT) #axtls_CFLAGS = $(CFLAGS) -Wno-address diff --git a/common.mk b/common.mk index 1c2424f..6772ba8 100644 --- a/common.mk +++ b/common.mk @@ -200,6 +200,7 @@ all: $(PROGRAM_OUT) $(FW_FILE_1) $(FW_FILE_2) $(FW_FILE) # Expects that the following component-specific variables are defined: # # $(1)_ROOT = Top-level dir containing component.
