Install JDK 1.6 (recommended installation way), chmod a+x jdk-6u29-linux-x64.bin,./jdk-6u29-linux-x64.bin,Install Software,Configure Build Profile,gedit /.bashrc,Add you Java folder to System Path,source /.bashrc,(Not nessary, it will also be set by,mbldenv.sh,when,makeMtk,),Install Software,Configure Build Profile,gedit mbldenv.sh,then change the,Java,eabi, and,python,path for your computer,Take mine for example:,Install Software,Check Environment,If having finished installing your environment to build ALPS,You can use this command,./makeMtk check-env,to know if the environment is prepared,Install Software,Check Environment,From the sceenshot above, we know my environment is failed for my low physical memory.,Sometime our computers may not meet the lowest hardware requriement for APLS,So we need to cheat in environment check.,gedit mediatek/build/tools/checkEnv.py,Install Software,Check Environment,Now the environment is OK,Of course, you can change “,checkEnv.py,” for other failure if necessary.,Install Software,Build a new project,Take tinnopmt73_gb for Example,./makeMtk listp,You will get all the project supported in your source code,Build the whole project tinnopmt73_gb,./makeMtk tinnopmt73_gb r,Notice: If you fail in building android, try,make update-api,in ALPS root directory,Install Software,Build a new project,Install Software,Build a new project,You can review the logs in,/out/target/product, if there are any errors.,Install Software,Build a new project,You can find all you product images in,out/target/product/tinnopmt73_gb,Build ALPS,We use “makeMtk” build ALPS,If you type ./makeMtk or ./makeMtk h, you will get how to use the,makeMtk,Build ALPS,We use “makeMtk” build ALPS,Build ALPS,We use “makeMtk” build ALPS,For example,1.Build the whole project for tinnopmt73_gb,./makeMtk tinnopmt73_gb r,2.Build the Linux Kernel for tinnopmt73_gb,./makeMtk tinnopmt73_gb r k,./makeMtk tinnopmt73_gb bootimage,3. Build the Galley.apk for tinnopmt73_gb,./makeMtk tinnopmt73_gb r dr Gallery,Notice:,mk,is a link to makeMtk, so we can use,mk,to replace,makeMtk,Build ALPS,Build Scripts Introduction,1)makeMtk,./mbldenv.sh,#mentioned above, set your build env,If the following folders or files do not exsits, makeMtk will die,mediatek,mediatek/config,mediatek/build/tools,mediatek/config/$project/ProjectConfig.mk,Mainly use the following scripts,mediatek/build/makemtk.mk,Build ALPS,Build Scripts Introduction,2)makeMtk,.mk,It executes the command sent by makeMtk, like “custgen”, “rebuild”, “clean” and so on.,It will also save the,logs,for building.,Mainly uses the following scripts,mediatek/build/Makefile,defines several globe,variables in the function,codebase-path,for use,mediatek/build/custgen.mk,most important script which used by makeMtk.mk for “custgen”,Build ALPS,Build Scripts Introduction,3)custgen.mk,custgen.mk,is used to choose the source code and config for our own project.,Mainly use the following scripts,mediatek/build/,Makefile,mediatek/build/libs/,gmsl,mediatek/build/libs/,custom.mk,mediatek/build/libs/,config.mk,-The last three scripts is included in,mediatek/build/Makefile,The contents of custgen.mk is very simple,include mediatek/build/Makefile,$(call codebase-path),all: mtk-config-files mtk-custom-files,echo done,mtk-config-files := $(strip $(call mtk.config.generate-rules,mtk-config-files),mtk-custom-files := $(strip $(call mtk.custom.generate-rules,mtk-custom-files),Build ALPS,Build Scripts Introduction,3)custgen.mk,mediatek/build/libs/,gmsl,is an Extended Library for GNU make,It defines some API for make use,For example,define,path.split,$(patsubst %/,%,$(dir $(patsubst %/,%,$1) $(notdir $(patsubst %/,%,$1),endef,Usage:,$(call path.split, kernel/imgsensor/ov7675_yuv,/,ov7675yuv_Sensor.c),output is,kernel/imgsensor/ov7675_yuv ov7675yuv_Sensor.c,define,wildcard2,$(strip $(if $(wildcard $(1),$(wildcard $(1),$(wildcard $(subst ,$(subst ,$(1),endef,Build ALPS,Build Scripts Introduction,3)custgen.mk,mediatek/build/libs/,custom.mk,is used to choose the correct source code for our project,define,mtk.custom.generate-rules,$(if $(MTK_ROOT_CUSTOM),$(strip ,$(eval _custflist_ :=) $(eval _custfmap_ :=) $(eval _custfgen :=) ,$(foreach d,$(addprefix $(MTK_ROOT_CUSTOM)/,$(MTK_CUSTOM_FOLDERS),$(eval _dirs := $(call wildcard2,$(if $(2),$(addprefix $(d)/,$(2),$(d) ,$(if $(_dirs),$(eval _files := $(filter-out $(_custflist_), ,$(patsubst $(d)/%,%,$(shell find -L $(_dirs) ( ! -name .* ) -type f) ,$(foreach f,$(_files), ,$(eval _ := $(call,.mtk.custom.map-module,$f) ,$(if $_, ,$(eval _src_ := $(firstword $_) ,$(eval _des_ := $(lastword $_) ,$(eval _custflist_ += $(_src_) ,$(eval _custfmap_ += $(MTK_ROOT_CUSTOM_OUT)/$(_des_):$(d)/$(_src_) ,) ,) ,) ,) ,Build ALPS,Build Scripts Introduction,3)custgen.mk,$(eval # TODO pre-generated files should be enforced directly by architecture ) ,$(if $(3),$(foreach f,$(filter-out $(_custflist_),$(3), ,$(eval _g_ := $(MTK_ROOT_CUSTOM_OUT)/$(patsubst $(MTK_ROOT_CUSTOM)/$(MTK_PROJECT)/%,%,$(f) ,$(if $(filter $(addprefix $(MTK_ROOT_CUSTOM_OUT)/,$(_custflist_),$(_g_), ,$(eval _custfgen += $(_g_) $(eval _custflist_ += $(f) $(eval _custfmap_ += $(_g_):$(f) ,),) ,$(if $(call wildcard2,$(MTK_ROOT_CUSTOM_OUT),$(foreach f,$(filter-out $(_custfgen) $(foreach f,$(_custfmap_),$(word 1,$(subst :, ,$f),$(shell find $(if $(2),$(addprefix $(MTK_ROOT_CUSTOM_OUT)/,$(2),$(MTK_ROOT_CUSTOM_OUT) ,!
