# This is a "Prebuilt" Android Makefile provided as an example/template (or direct use if no tweaking is required).
5
+
# The idea is that you have already built the lua .so and .a libraries using CMake.
6
+
# Now you want to use those prebuilt libraries in your own project.
7
+
# Android support prebuilt exteneral modules through its ndk-build system, but you need to have all the pieces setup and in the right place. This is one of those pieces.
8
+
#
9
+
# This file assumes you built all your lua libs and put things into a directory structure like so:
10
+
#
11
+
# Android.mk (this file)
12
+
# libs/armeabi/liblua.a
13
+
# libs/armeabi/liblua.so
14
+
# libs/armeabi-v7a/liblua.a
15
+
# libs/armeabi-v7a/liblua.so
16
+
# libs/x86/liblua.a
17
+
# libs/x86/liblua.so
18
+
#
19
+
# include/lua/lua.h
20
+
# ... (the other header files here)
21
+
#
22
+
# Note that this file is copied into the directory above libs and include.
23
+
# Below is the code you need to make this Makefile export the correct headers, libraries, and flags for both dynamic and static versions.
24
+
25
+
# LOCAL_PATH needs to be before include
26
+
LOCAL_PATH := $(call my-dir)
27
+
28
+
# For the dynamic library
29
+
include $(CLEAR_VARS)
30
+
# This is the name of module the caller will use in LOCAL_SHARED_LIBRARIES
31
+
LOCAL_MODULE := SDL_gpu_shared
32
+
LOCAL_SRC_FILES := libs/$(TARGET_ARCH_ABI)/libSDL2_gpu.so
33
+
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include
34
+
# Use LOCAL_EXPORT_CFLAGS to automatically export the correct flags (as necessary) to the calling module so the caller doesn't need to know the details.
35
+
# LOCAL_EXPORT_CFLAGS :=
36
+
# The .so is already linked so we don't really need to export this.
37
+
#LOCAL_EXPORT_LDLIBS := -lm
38
+
include $(PREBUILT_SHARED_LIBRARY)
39
+
40
+
41
+
## For the static library
42
+
#include $(CLEAR_VARS)
43
+
## This is the name of module the caller will use in LOCAL_STATIC_LIBRARIES
44
+
#LOCAL_MODULE := ALmixerLuaBindings_static
45
+
#LOCAL_SRC_FILES := libs/$(TARGET_ARCH_ABI)/libALmixerLuaBindings.a
46
+
# Use LOCAL_EXPORT_CFLAGS to automatically export the correct flags (as necessary) to the calling module so the caller doesn't need to know the details.
47
+
#LOCAL_EXPORT_CFLAGS :=
48
+
## Since the .a isn't linked, it's link dependencies must be passed on to the calling project.
49
+
# LOCAL_EXPORT_LDLIBS :=
50
+
#LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include/lua
51
+
#include $(PREBUILT_STATIC_LIBRARY)
52
+
53
+
54
+
55
+
# Two other pieces are needed to make this work which fall outside the scope of this file.
56
+
# First, you must have a directory convention for the calling makefile.
57
+
# So let's say we put all the above in a directory called lua. The layout looks like this:
58
+
# lua/
59
+
# Android.mk (this file)
60
+
# libs/armeabi/liblua.a
61
+
# libs/armeabi/liblua.so
62
+
# libs/armeabi-v7a/liblua.a
63
+
# libs/armeabi-v7a/liblua.so
64
+
# libs/x86/liblua.a
65
+
# libs/x86/liblua.so
66
+
#
67
+
# include/lua.h
68
+
# ... (the other header files here)
69
+
70
+
# So the calling makefile looks something like:
71
+
# LOCAL_PATH := $(call my-dir)
72
+
# include $(CLEAR_VARS)
73
+
# LOCAL_MODULE := hello-jni
74
+
# LOCAL_SRC_FILES := hello-jni.c
75
+
# These are the LOCAL_MODULE names as defined in the prebuilt module's Android.mk. Define either shared or static, but not both. If you use dynamic, don't forget you need to do a System.loadLibrary("lua") in your Java code.
76
+
# LOCAL_SHARED_LIBRARIES := lua_shared
77
+
# #LOCAL_STATIC_LIBRARIES := lua_static
78
+
# include $(BUILD_SHARED_LIBRARY)
79
+
# Android build system will look for folder `lua` in all import paths:
80
+
# $(call import-module,lua)
81
+
# ------ end -----
82
+
83
+
# Second, you need to set the environmental variable NDK_MODULE_PATH to list the directory containing lua.
84
+
# So if lua is in /Library/Frameworks/Android/PrebuiltModules
85
+
# export NDK_MODULE_PATH=/Library/Frameworks/Android/PrebuiltModules
86
+
# Note that NDK_MODULE_PATH may contain multiple directories like the PATH environmental variable.

+
# Android CMake toolchain file, for use with the Android NDK r5-r8
3
+
# Requires cmake 2.6.3 or newer (2.8.5 or newer is recommended).
4
+
# See home page: http://code.google.com/p/android-cmake/
5
+
#
6
+
# The file is mantained by the OpenCV project. And also can be found at
7
+
# http://code.opencv.org/projects/opencv/repository/revisions/master/changes/android/android.toolchain.cmake
8
+
#
9
+
# Note: There are now two flavors of this toolchain file: 32-bit toolchain and 64-bit toolchain.
10
+
#
11
+
# Usage Linux:
12
+
# $ export ANDROID_NDK_ROOT=/absolute/path/to/the/android-ndk
13
+
# $ mkdir build && cd build
14
+
# $ cmake -DCMAKE_TOOLCHAIN_FILE=path/to/the/android.toolchain.cmake ..
15
+
# $ make -j8
16

#
17

# Usage Linux (using standalone toolchain):
18

# $ export ANDROID_STANDALONE_TOOLCHAIN=/absolute/path/to/android-toolchain
19
+
# $ mkdir build && cd build
20
+
# $ cmake -DCMAKE_TOOLCHAIN_FILE=path/to/the/android.toolchain.cmake ..
21
+
# $ make -j8
22
+
#
23
+
# Usage Windows:
24
+
# You need native port of make to build your project.
25
+
# Android NDK r7 (or newer) already has make.exe on board.
26
+
# For older NDK you have to install it separately.
27
+
# For example, this one: http://gnuwin32.sourceforge.net/packages/make.htm

# Options (can be set as cmake parameters: -D<option_name>=<value>):
38
+
# ANDROID_NDK=/opt/android-ndk - path to the NDK root.
39
+
# Can be set as environment variable ANDROID_NDK_ROOT. Can be set only at first cmake run.
40
+
#
41
+
# ANDROID_STANDALONE_TOOLCHAIN=/opt/android-toolchain - path to the
42

# standalone toolchain. This option overrides ANDROID_NDK
43
+
# (and subsequentally the enviroment variable ANDROID_NDK_ROOT).
44
+
# Can be set as environment variable. Can be set only at first cmake run.
45
+
#
46
+
# ANDROID_ABI=armeabi-v7a - specifies the target Application Binary
47
+
# Interface (ABI). This option nearly matches to the APP_ABI variable
48
+
# used by ndk-build tool from Android NDK.
49
+
#
50
+
# Possible targets are:
51
+
# "armeabi" - matches to the NDK ABI with the same name.
52
+
# See ${ANDROID_NDK_ROOT}/docs/CPU-ARCH-ABIS.html for the documentation.
53
+
# "armeabi-v7a" - matches to the NDK ABI with the same name.
54
+
# See ${ANDROID_NDK_ROOT}/docs/CPU-ARCH-ABIS.html for the documentation.
55
+
# "armeabi-v7a with NEON" - same as armeabi-v7a, but
56
+
# sets NEON as floating-point unit
57
+
# "armeabi-v7a with VFPV3" - same as armeabi-v7a, but
58
+
# sets VFPV3 as floating-point unit (has 32 registers instead of 16).
59
+
# "armeabi-v6 with VFP" - tuned for ARMv6 processors having VFP.
60
+
# "x86" - matches to the NDK ABI with the same name.
61
+
# See ${ANDROID_NDK_ROOT}/docs/CPU-ARCH-ABIS.html for the documentation.
62
+
# "mips" - matches to the NDK ABI with the same name
63
+
# (not testes on real devices)
64
+
#
65
+
# ANDROID_NATIVE_API_LEVEL=android-8 - level of Android API compile for.
66
+
# Option is read-only when standalone toolchain used.
67
+
#
68
+
# ANDROID_FORCE_ARM_BUILD=OFF - set true to generate 32-bit ARM instructions
69
+
# instead of Thumb-1. Is not available for "x86" (inapplicable) and
70
+
# "armeabi-v6 with VFP" (forced) ABIs.
71
+
#
72
+
# ANDROID_NO_UNDEFINED=ON - set true to show all undefined symbols as linker
73
+
# errors even if they are not used.
74
+
#
75
+
# ANDROID_SO_UNDEFINED=OFF - set true to allow undefined symbols in shared
76
+
# libraries. Automatically turned on for NDK r5x and r6x due to GLESv2
77
+
# problems.
78
+
#
79
+
# LIBRARY_OUTPUT_PATH_ROOT=${CMAKE_SOURCE_DIR} - where to output binary
80
+
# files. See additional details below.
81
+
#
82
+
# ANDROID_SET_OBSOLETE_VARIABLES=ON - it set, then toolchain defines some
83

# obsolete variables which were set by previous versions of this file for
84
+
# backward compatibility.
85
+
#
86
+
#
87
+
# What?:
88
+
# android-cmake toolchain searches for NDK/toolchain in the following order:
89
+
# ANDROID_NDK - cmake parameter
90
+
# ANDROID_NDK_ROOT - environment variable
91
+
# (ANDROID_NDK - environment variable as legacy fallback)
92
+
# ANDROID_STANDALONE_TOOLCHAIN - cmake parameter
93
+
# ANDROID_STANDALONE_TOOLCHAIN - environment variable
94
+
# ANDROID_NDK - default locations
95
+
# ANDROID_STANDALONE_TOOLCHAIN - default locations
96
+
#
97
+
# Make sure to do the following in your scripts:
98
+
# SET( CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${my_cxx_flags}" )
99
+
# SET( CMAKE_C_FLAGS "${CMAKE_C_FLAGS} ${my_cxx_flags}" )
100
+
# The flags will be prepopulated with critical flags, so don't loose them.
101
+
# Also be aware that toolchain also sets configuration-specific compiler
102
+
# flags and linker flags.
103
+
#
104
+
# ANDROID and BUILD_ANDROID will be set to true, you may test any of these
105
+
# variables to make necessary Android-specific configuration changes.
106
+
#
107
+
# Also ARMEABI or ARMEABI_V7A or X86 will be set true, mutually exclusive.
108
+
# NEON option will be set true if VFP is set to NEON.
109
+
#
110
+
# LIBRARY_OUTPUT_PATH_ROOT should be set in cache to determine where Android
111
+
# libraries will be installed.
112
+
# Default is ${CMAKE_SOURCE_DIR}, and the android libs will always be
113
+
# under the ${LIBRARY_OUTPUT_PATH_ROOT}/libs/${ANDROID_NDK_ABI_NAME}
114
+
# (depending on the target ABI). This is convenient for Android packaging.

176
+

177
+
# - modified March 2012
178
+
# [~] fixed incorrect C compiler flags
179
+

180
+

181
+
# [+] added assembler language support (.S)
182
+

183
+
# - modified April 2012
184
+
# [+] updated for NDK r7c

188
+

189
+
# [+] added mips architecture support
190
+
# - modified August 2012
191

195
+
# [+] updated for NDK r9 (standalone)

+
# [+] Addded Perl helper scripts to make it easier to build multiple architectures in one shot.
197
+
# [~] Breaking change of behavior to so that ANDROID_STANDALONE_TOOLCHAIN overrides ANDROID_NDK because the latter uses semi-standard environmental variables that people may already have defined for other conflicting purposes.
198
+
# [~] Changed environmental variable to look for ANDROID_NDK_ROOT because this is the semi-official/blessed one according to Google via the NDK mailing list. ANDROID_NDK is still checked for backwards compatibility.
199
+
# [~] Changed a lot of flags to try to match stock Android more closely due build problems I was trying to track down. In the end, I lost track of which specific flags were the problem. See Additional Notes for flag differences between this and stock.
200
+
# [~] Changed armeabi-v7a to use -mfpu=vfpv3-d16 instead of -mfpu=vfp to conform with stock Android.
201
+
# [~] Changed VFPV3 mode to use -mfpu=vfpv3-d32
202
+
# [~] Use --sysroot=${ANDROID_SYSROOT} to match stock Android
203
+
# [~] Use -fstack-protector -no-canonical-prefixes -Wa,--noexecstack to match stock Android
204
+
# [~] Use -no-canonical-prefixes -Wl,--no-undefined -Wl,-z,noexecstack -Wl,-z,relro -Wl,-z,now to match stock Android
205
+
# [~] Use -lc -lm to match stock Android
206
+
# [~] Removed -fsigned-char and -Wno-psabi because these don't appear in stock Android
207
+
# [~] Removed -f[no]exceptions flags from C flags because those are C++ options
208
+
# [~] Changed arm debug optimization level to O0 from Os
209
+
# [~] Added -funswitch-loops -finline-limit=300 to match stock Android
210
+
# [~] Changed arm debug optimization level to O0 from Os
211
+
# [~] Separated ANDROID_CXX_FLAGS into ANDROID_CXX_FLAGS and ANDROID_C_FLAGS
212
+
# [*] Note: MIPs settings were not changed/tested.

288

289

# -funwind-tables has been completely removed for arm by this file. It looks like the author intentionally did this for performance.

# Optimization flags are using O3 in this file as opposed to stock 02 for Release. It looks like the original authors have done some benchmarking so I am deferring to them.
