clang 报错

修改 alps/art/build/android.common_build.mk 大概81行

-- ifneq ($(WITHOUT_HOST_CLANG),true)
++ ifeq ($(WITHOUT_HOST_CLANG),false)

如果解决，那么 OK。
如果没有解决。还需要如下修改：

# 请自行做好原始 ld 的备份
cp /usr/bin/ld.gold prebuilts/gcc/Linux-x86/host/x86_64-linux-glibc2.11-4.6/x86_64-linux/bin/ld
make update-api
make -j8 # 重新编译

如果仍然有报错，
那么回退上述的所有修改，修改 build/core/clang/HOST_x86_common.mk：

CLANG_CONFIG_x86_LINUX_HOST_EXTRA_CFLAGS := \

libcam 无法编译的问题

错误信息：

1
make: *** No rule to make target 'out/target/product/br6737m_65_s_m0/obj_arm/STATIC_LIBRARIES/libcam.halmemory_intermediates/export_includes', needed by 'out/target/product/br6737m_65_s_m0/obj_arm/SHARED_LIBRARIES/libcam_platform_intermediates/import_includes'.  Stop

解决方法：

aiiage@repo:~/alps$ cp -a vendor/mediatek/proprietary/hardware/mtkcam/legacy/platform/mt6735m/hal/memory vendor/mediatek/proprietary/hardware/mtkcam/legacy/platform/mt6735m/entry/

烧录问题@Linux

S_BROM_CMD_JUMP_DA_FAIL

是由于 Ubuntu14.04 / 16.04 环境问题。

是由于modemmanager包在ubuntu 14.04 或是更高版本中对于MTK的Flash 工具支持不完全，所造成的，如果想使用MTK的Flash工具，就要卸载这个包

sudo apt-get remove modemmanager    //卸载modemmanager包
sudo service udev restart       //从启udev

# 卸载这个服务之后可能会造成内核模块　cdc_acm　不可用．执行以下命令进行检查
lsmod | grep cdc_acm            //检查    

# 执行后出现：
	cdc_acm                36864  0     //表示可用

# 如果没有任何输出：
	sudo modprobe cdc_acm           //智能安装cdc_acm

ok

如果出现pmt changed for the rom; it must be downloaded这个错误，则选择固件升级，便可以下载。

S_INVALID_BBCHIP_TYPE

芯片类型不匹配

可能是 lunch 错工程。
