How to build Boost in Android NDK?

I am trying to debug v8 in my Android app.
I integrated v8 and it is currently running.
I've found this repo which seems to be interesting as a starting point:
https://github.com/ahmadov/v8_inspector_example
This implementation uses Boast.Beast for socket related operations.
I got a Boast.Beast build for Android by using:
https://github.com/moritz-wundke/Boost-for-Android
I already imported libs and includes into my project and now I am trying to build NDK, but I have some problems with headers' files.
My Android.mk looks like this:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := v8_monolith
LOCAL_SRC_FILES := v8-dist/dist/$(TARGET_ARCH_ABI)/libv8_monolith.a
include $(PREBUILT_STATIC_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE := boost
LOCAL_SRC_FILES := boost/dist/$(TARGET_ARCH_ABI)/lib/libboost_system-clang-1_80.a
LOCAL_CPPFLAGS := \
-fexceptions \
-frtti
include $(PREBUILT_STATIC_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE := en8
LOCAL_C_INCLUDES := \
$(LOCAL_PATH) \
$(LOCAL_PATH)/v8-dist/include
BOOST := $(wildcard $(LOCAL_PATH)/boost/include/*.hpp)
LOCAL_C_INCLUDES += $(BOOST:$(LOCAL_PATH)/%=%)
LOCAL_SRC_FILES := \
en8.cpp \
marshall.cpp \
instrument.cpp \
localstorage.cpp \
runtime.cpp \
cpu_profile.cpp \
page_size.cpp \
disk_cleanup.cpp
LOCAL_CPPFLAGS := \
-std=c++17 \
-Wall \
-Wextra \
-Wpedantic \
-Wno-unused-parameter \
-Wno-variadic-macros \
-Wno-gnu-include-next \
-DV8_DEPRECATION_WARNINGS \
-DLEVELDB_PLATFORM_ANDROID
# Pointer compression should be enabled for 64-bit archs
ifeq ($(TARGET_ARCH), $(filter $(TARGET_ARCH),arm64 x86_64))
LOCAL_CPPFLAGS += -DV8_COMPRESS_POINTERS
endif
LOCAL_LDLIBS := -llog
LOCAL_STATIC_LIBRARIES := v8_monolith leveldb boost
include $(BUILD_SHARED_LIBRARY)
I am trying to import this files:
#include <boost/beast/core.hpp>
#include <boost/beast/websocket.hpp>
#include <boost/asio/ip/tcp.hpp>
When building NDK I get: fatal error: 'boost/beast/core.hpp' file not found
Thanks.

ndk-build No rule to make target

This is my android.mk:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
FREETYPE_SRC_PATH :=
LOCAL_MODULE := freetype
LOCAL_CFLAGS := -DANDROID_NDK \
-DFT2_BUILD_LIBRARY=1
LOCAL_C_INCLUDES := $(LOCAL_PATH)/include_all \
$(FREETYPE_SRC_PATH)include \
$(FREETYPE_SRC_PATH)src
LOCAL_SRC_FILES := \
$(FREETYPE_SRC_PATH)src/autofit/autofit.c \
$(FREETYPE_SRC_PATH)src/base/basepic.c \
$(FREETYPE_SRC_PATH)src/base/ftapi.c \
$(FREETYPE_SRC_PATH)src/base/ftbase.c \
LOCAL_LDLIBS := -ldl -llog
include $(BUILD_SHARED_LIBRARY)
And this is Application.mk:
APP_PLATFROM := android-20
APP_ABI := armeabi-v7a x86
After i hit ndk-build on the terminal Android Studio, i got an error message:
make: *** No rule to make target '/app/src/main/jni/src/base/basepic.c
I've checked android.mk:
$(FREETYPE_SRC_PATH)src/autofit/autofit.c \
$(FREETYPE_SRC_PATH)src/base/basepic.c \
there is no whitespace. But still got an error.
Gradle model version=6.0.1, NDK version=21.1.6352462
I need to ndk-build without problem.. any i can do to solve this issue?

In your android.mk file you have FREETYPE_SRC_PATH empty. I guess it must be assigned as /app/src/main/jni/.

Any help will appreciate

If you use LOCAL_MODULE := libjni_terminal in any other project this error will happen.
When using the same LOCAL_MODULE name in different places lead to problems while creating and accessing intermediate files.

Compiling native android library with multiple c files using ndk build errors * No rule to make target

I am having an issue compiling a shared C library into a .so for android. I've copied all the .c and .h files into the jni folder. I posted a screenshot below to show the contents of the Android.mk file as well as the folder hierarchy.
below is the output of ndk-build run in the project root folder NTRUMLS
[kenway#jackdaw NTRUMLS]$ ndk-build
make: *** No rule to make target '/media/bigdata/Android/Sdk/ndk-bundle/build/core/crypto_hash_sha512.c', needed by 'obj/local/arm64-v8a/objs/ntrumls/crypto_hash_sha512.o'. Stop.
i checked for spaces and typo's. here's the contents of my Android.mk copied directly below.
include $(CLEAR_VARS)
LOCAL_ARM_MODE := arm
LOCAL_PATH := $(call my-dir)
LOCAL_MODULE := libntrumls
LOCAL_CFLAGS := -Werror
LOCAL_SRC_FILES := crypto_hash_sha512.c \

Move
LOCAL_PATH := $(call my-dir)
to be the first statement of your Android.mk script.

Try following
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_ARM_MODE := arm
LOCAL_MODULE := libntrumls
LOCAL_CFLAGS := -Werror
LOCAL_SRC_FILES := Main_M1_play.cpp
LOCAL_LDLIBS := -llog
include $(BUILD_SHARED_LIBRARY)

how to config android.mk when i need to export several native library

Now i export one native library and my folder is like this :
JNI\ANN*.cpp.
android.mk file is like this:
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_C_INCLUDES := $(LOCAL_PATH)/../
LOCAL_MODULE := libann
LOCAL_LDLIBS := -llog
NDK_TOOLCHAIN_VERSION := clang
LOCAL_CPPFLAGS += -std=c++11
LOCAL_SRC_FILES := \
ANN.cpp \
bd_pr_search.cpp \
bd_tree.cpp \
kd_pr_search.cpp \
kd_split.cpp \
kd_util.cpp \
bd_fix_rad_search.cpp \
bd_search.cpp \
brute.cpp \
kd_fix_rad_search.cpp \
kd_search.cpp \
kd_tree.cpp \
kd_dump.cpp \
perf.cpp\
sample.cpp
include $(BUILD_SHARED_LIBRARY)
Now i want to add some other cpp files and export another native lib.
for example, i add two files: graph.h,dijkstra,cpp
how should i config the android.mk file?
