22. 編譯報錯分析

常見編譯報錯彙總

關鍵字：
	error:
	make[
	FAILED:
	multiple definition

1. 攝像頭兼容個數超過16個 - 增大爲18個
	alps\kernel-3.18\drivers\misc\mediatek\imgsensor\src\mt6735m\kd_sensorlist.h
	#define MAX_NUM_OF_SUPPORT_SENSOR 16
	ACDK_KD_SENSOR_INIT_FUNCTION_STRUCT kdSensorList[MAX_NUM_OF_SUPPORT_SENSOR]=
	{
		...
	}
	
	報錯log: 
	excess elements in array initializer(給數組塞了超過初始化個數的元素)

		 {T4KA3_SENSOR_ID, SENSOR_DRVNAME_T4KA3_MIPI_RAW, T4KA3_MIPI_RAW_SensorInit},

2. 安卓5.1 新增驅動需要在alps\kernel-3.10\drivers\misc\mediatek\Kconfig.drivers中建宏

3. makefile從安卓6.0移植到安卓5.1，需要修改
	參照同一目錄其他Makefile修改

4. 缺少頭文件包含 - （安卓5.1）
	fae提供的代碼qma6981.c, 沒有包含包含頭文件accel.h, 導致編譯移植報結構體struct sensor_init_info定義不一致
	+	#include <accel.h>
	
	報錯log: 
	alps/kernel-3.10/drivers/misc/mediatek/accelerometer/qma6981/qma6981.c: In function 'qma6981_init':

	  acc_driver_add(&qma6981_init_info);
	  ^

5. 報錯信息爲轉義字符 - 服務器加密問題 - 重啓編譯服務器
	報錯log: 
	Line 2780: ./build/core/combo/include/arch/linux-arm/AndroidConfig.h:1:1: error: stray '\24' in program
	Line 2784: ./build/core/combo/include/arch/linux-arm/AndroidConfig.h:1:3: error: stray '#' in program

	Line 2819: ./build/core/combo/include/arch/linux-arm/AndroidConfig.h:1:13: error: stray '\320' in program

6. 兩個.c文件中重複定義 - 修改其中一個名字
	報錯log: 
	alps/kernel/mediatek/custom/out/kernel/accelerometer/mxc622x.c:1319: multiple definition of `gsensor_operate'
	mediatek/custom/out/kernel/accelerometer/mxc400x.o:alps/kernel/mediatek/custom/out/kernel/accelerometer/mxc400x.c:1845: first defined here
	make[4]: *** [mediatek/custom/out/kernel/built-in.o] Error 1
	
7. 編譯服務器空間不足 - [No space left on device] - 清除服務器多餘存儲
	例1:
	cp: writing `out/target/product/magc6580_we_t_n/obj/EXECUTABLES/e2fsck_intermediates/quota.P': No space left on device
	cp: failed to extend `out/target/product/magc6580_we_t_n/obj/EXECUTABLES/e2fsck_intermediates/quota.P': No space left on device

8. BoardConfig.mk分區不足

	！！！默認的分區，及大小是寫在alps/device/mediatek/build/build/tools/ptgen/MT6737M/partition_table_MT6737M.xls中
	此中方式只能修改大小，不能重新劃分分區
	
	1. 修改alps/device/haocheng/hct6580_we_a_l/BoardConfig.mk 在最後添加：
		BOARD_MTK_SYSTEM_SIZE_KB :=  1835008				// 需要比文件夾略大: alps\out\target\product\hct6580_weg_a_l\system
		BOARD_MTK_USERDATA_SIZE_KB :=  786432				// 注意大小是16的倍數
	2. rm –rf out\target\product\$PROJECT_NAME \obj\PTGEN	// 【重要】裏面有分區表，不刪除不會生效！！！
	3. source xxx; lunch xxx; make lk;						// 【重要】重新生成 MT6580_Android_scatter.txt	
	4. 查看【system】分區大小是否成功改變
		vi out/target/product/hct6580_weg_a_l/MT6580_Android_scatter.txt
			partition_index: SYS19
			partition_name: system			// 關鍵字[system]
			file_name: system.img
			is_download: true
			type: EXT4_IMG
			linear_start_addr: 0xa800000
			physical_start_addr: 0xa800000
		-	partition_size: 0x60000000		// 原本報錯的時候
		+	partition_size: 0x70000000		// 修改之後生成
			region: EMMC_USER
			storage: HW_STORAGE_EMMC
			boundary_check: true
			is_reserved: false
			operation_type: UPDATE
			reserve: 0x00
	5. Make snod 或 make systemimage	

	log:
	Target system fs image: out/target/product/hct6580_weg_a_l/obj/PACKAGING/systemimage_intermediates/system.img
	error: ext4_allocate_best_fit_partial: failed to allocate 3060 blocks, out of space?
	error: failed to build out/target/product/hct6580_weg_a_l/obj/PACKAGING/systemimage_intermediates/system.img from out/target/product/hct6580_weg_a_l/system

	Out of space? the tree size of out/target/product/hct6580_weg_a_l/system is (MB): 
	1511	out/target/product/hct6580_weg_a_l/system
	The max is 1536 MB.
	make: *** [out/target/product/hct6580_weg_a_l/obj/PACKAGING/systemimage_intermediates/system.img] Error 1

	#### make failed to build some targets (01:03:06 (hh:mm:ss)) ####

9. android.mk
	./vendor/mediatek/proprietary/hardware/sensor/Android.mk:59: *** commands commence before first target
	
	在C/C++語言中，可以用\來換行，此時要注意，在一行的最後面加上\, 而這個\後面不能再有任何字符，哪怕是空格，也不允許，否則出錯。
    對於makefile,也有類似的原則,最近寫makefile,一不小心,在\後多了個空格,結果編譯出現：commands commence before first target
	
10. kernel-3.18\arch\arm64\configs\k37mv1_64_bsp_debug_defconfig、k37mv1_64_bsp_defconfig
	-	CONFIG_FRAME_WARN=1400
	+	CONFIG_FRAME_WARN=1500
	
	函數調用棧過深，內核配置的棧緩存不夠用
