Compile OpenSSL for Android with Bazel

Question

I'm building a native library for my Android application with bazel.

I'd like to use some OpenSSL functions on it like this:

#include <jni.h>
#include <openssl/aes.h>
...
AES_encrypt(in, out, key);

How to add the openssl library to bazel build ?

Subsidiary question: which archive I should use ?

openssl-1.1.0c.tar.gz
openssl-1.0.2j.tar.gz
openssl-1.0.1u.tar.gz
openssl-fips-2.0.13.tar.gz
openssl-fips-ecp-2.0.13.tar.gz

What I've tried

I've downloaded the openssl-1.0.2j archive. and added a cc_library entry to my BUILD file.

cc_library(
    name = "openssl",
    srcs = glob([
         "openssl-1.0.2j/crypto/**/*.h",
         "openssl-1.0.2j/crypto/**/*.c"
         ]),
    includes = [
        "openssl-1.0.2j",
        "openssl-1.0.2j/crypto/",
        ],
    visibility = ["//visibility:public"],
)

I've this error:

openssl-1.0.2j/crypto/dh/p512.c:60:24: fatal error: openssl/bn.h: No such file or directory
 #include <openssl/bn.h>

But I don't understand why this code is trying to include a file from openssl while it's in openssl-1.0.2j/crypto/

With openssl-1.1.0c

openssl-1.1.0c/include/openssl/e_os2.h:13:34: fatal error: openssl/opensslconf.h: No such file or directory
 # include <openssl/opensslconf.h>

Even if I run the Configure command, no opensslconf.h file is generated.

Answer 1

Based on @Ulf Adams' answer, I gave up trying to compile OpenSSL with bazel. I used BoringSSL instead.

BoringSSLis a fork of OpenSSL, and can easily be incorporated to a bazel project by doing:

git_repository(
    name = "boringssl",
    commit = "_some commit_",
    remote = "https://boringssl.googlesource.com/boringssl",
)
