Compile errors due to missing headers in OpenSSL project

Question

I am using preBuilt library of OpenSSL in project but i am getting error as:

Error:(62, 11) fatal error: 'openssl/asn1.h' file not found
Error:(62, 11) fatal error: 'openssl/asn1.h' file not found

and my Android.mk file is here

Android.mk

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE := myLibrary
TARGET_PLATFORM := android-3
LOCAL_SRC_FILES := native-lib.cpp
LOCAL_C_INCLUDES = $(LOCAL_PATH)/src/main/jni/include/openssl
LOCAL_LDLIBS := -llog

include $(BUILD_SHARED_LIBRARY)

getting error in rss.h

headers of rsa.h

# include <openssl/asn1.h>    
# ifndef OPENSSL_NO_BIO
#  include <openssl/bio.h>
# endif
# include <openssl/crypto.h>
# include <openssl/ossl_typ.h>
# ifndef OPENSSL_NO_DEPRECATED
#  include <openssl/bn.h>
# endif

the error here is cannot find OpenSSL

I have added .so files in appropriate folders. its been four days I am not able to fix this.

please help me guys.

What does `$(LOCAL_PATH)/src/main/jni/include/openssl` resolve to, and does `$(LOCAL_PATH)/src/main/jni/include/openssl/openssl/asn1.h` indeed exist? By the way, why are you setting `android-3` in your native makefile when your `minSdkVersion` is 19? — Michael, Jan 29 '18 at 09:00
@Michael Yes asn1.h file exist i checked in the include folder. — Gaju Kollur, Jan 29 '18 at 09:04
I'm sure the file exists _somewhere_, but does it exist _exactly_ at whatever `$(LOCAL_PATH)/src/main/jni/include/openssl/openssl/asn1.h` resolves to? (and not e.g. at `$(LOCAL_PATH)/src/main/jni/include/openssl/asn1.h`)? Also, note that those .h files may actually be symlinks, which may or may not work on Windows. — Michael, Jan 29 '18 at 09:12
@Michael file exactly exist here $(LOCAL_PATH)/src/main/jni/include/openssl..but totally openssl is not recognising ..i am using Ubuntu — Gaju Kollur, Jan 29 '18 at 09:19
_" file exactly exist here $(LOCAL_PATH)/src/main/jni/include/openssl"_ Then shouldn't you be adding `(LOCAL_PATH)/src/main/jni/include` to `LOCAL_C_INCLUDES`, if you expect statements like `#include ` to work? Btw, it looks like you've got a typo in your makefile: the `=` after `LOCAL_C_INCLUDES` ought to be either `:=` or `+=`. — Michael, Jan 29 '18 at 09:36
Also see [use libcryto.so and libssl.so in an android project?](https://stackoverflow.com/q/22531390/608639). — jww, Jan 29 '18 at 16:55

Your Android.mk is in ${proj}/src/main/jni, which becomes your $(LOCAL_PATH). Therefore, you should use

LOCAL_C_INCLUDES := $(LOCAL_PATH)/include

This will find ${proj}/src/main/jni/include/openssl/asn1.h as

#include <openssl/asn1.h>
