Here is the solution, updated to NDK8c
step zero: download and fix the Android NDK
I don't know how but the ndk has a very interesting flaw, which (in my oppinion) doesn't allow you to compile lot's of stuff, so to be able to compile OpenSSL you need to make a small fix, extract the ndk8c whereever you keep your tools, and then edit the file :
android-ndk-r8c/build/gmsl/__gmsl
line 512 :
change line
int_encode = $(__gmsl_tr1)$(wordlist 1,$1,$(__gmsl_input_int))
with line
int_encode = $(__gmsl_tr1)$(wordlist 1,$(words $1),$(__gmsl_input_int))
And you're good to go!
step one : Download OpenSSL and compile for Android :
either compile a ported version found here
or Download the official 1.0.0c version of OpenSSL and then compile it for android using the manual provided in the github I linked for the Android compatible version
So the next step is to get the libssl.so and libcrypto.so
and put the them in the NDK folder for easy access, so copy them from
openssl-folder/libs/armeabi/
to
android-ndk-r8c/platforms/android-8/arch-arm/usr/lib
this way when compiling you can include the libs using a simple linker switch -lssl -lcrypto
Step two : get Curl's latest source for here
Open the file in Docs/INSTALL and follow the steps needed to make the standalone toolchain and put in your desired folder, and then the tricky part, I needed to have android's source code for the config to continue, even though I have a standalone compiled openssl you can include the header files from there too, in anycase this is the more complicated version so you choose what you do, I did not choose to evade them so you can go to Google AOSP site and go trough the steps to build and initialize the environment.
so it would be something like :
1.download,
go to root of the source code and run :
~: build/envsetup.sh; lunch 1; make;
So finally we need to compile curl with SSL support, so,
Step three
extract curl to the desired folder
(I have a specific desire of disabling everything except http/s to keep the library as small as possible meaning about ~300k, if you want more protocols in your lib, remove the --disable-protocol for the desired protocol)
run the following :
make clean
export PATH=/opt/arm-linux-androideabi-4.4.3/bin:$PATH
export LDFLAGS="
-lssl
-lcrypto
-L/home/user/Development/Tools/sdk/android/ndk/platforms/android-8/arch-arm/usr/lib"
export CFLAGS="
-I/home/user/Development/AOSP/2.3.7/system/core/include
-I/home/user/Development/Tools/sdk/android/ndk/platforms/android-8/arch-arm/usr/include"
./configure --host=arm-linux-androideabi
--with-ssl=/home/user/Development/Projects/portingLibs/openssl-android-master
--disable-ftp
--disable-gopher
--disable-file
--disable-imap
--disable-ldap
--disable-ldaps
--disable-pop3
--disable-proxy
--disable-rtsp
--disable-smtp
--disable-telnet
--disable-tftp
--without-gnutls
--without-libidn
--without-librtmp
--disable-dict
make
Note that in the block above, if you don't want to use the AOSP source, you could switch
-I/home/user/Development/AOSP/2.3.7/system/core/include
with the include folder for your ssl distribution.
So finally you have :
static :
curl-7.28.1/lib/.libs/libcurl.a
and shared :
curl-7.28.1/lib/.libs/libcurl.so.5.3
So that's it.. take the file, and compile away :)
