How to build OpenSSL on macOS for Android Arm / x86 ? ( removing '-mandroid' from Makefile helps )

[esutton]

Building OpenSSL on macOS is a challenge!! One day wasted and counting...

• Qt 5.9 Android app works fine on Android Kit Kat 4.4.
• On Android 7.0 I get run time messages:

qt.network.ssl: QSslSocket: cannot call unresolved function SSL_CTX_ctrl

I got past the '-mandroid' issue by removing it from the Makefile

What I have tried so far:

Qt 5.9 Adding OpenSSL Support for Android

Follow this first: Qt 5.9 Adding OpenSSL Support for Android

File: Setenv-android.sh

_ANDROID_NDK="android-ndk-r9"
_ANDROID_EABI="arm-linux-androideabi-4.9"
# _ANDROID_ARCH=arch-x86
_ANDROID_ARCH=arch-arm

Attempt to build OpenSSL

1. Edit Makefile.shared to remove -Bsymbolic
2. Edit Makefile.shared to replace -soname with -install_name

Example:

#DO_GNU_SO=$(CALC_VERSIONS); \
#	SHLIB=lib$(LIBNAME).so; \
#	SHLIB_SUFFIX=; \
#	ALLSYMSFLAGS='-Wl,--whole-archive'; \
#	NOALLSYMSFLAGS='-Wl,--no-whole-archive'; \
#	SHAREDFLAGS="$(CFLAGS) $(SHARED_LDFLAGS) -shared -Wl,-Bsymbolic -Wl,-soname=$$SHLIB$$SHLIB_SOVER$$SHLIB_SUFFIX"
# https://stackoverflow.com/questions/4580789/ld-unknown-option-soname-on-os-x

O_GNU_SO=$(CALC_VERSIONS); \
	SHLIB=lib$(LIBNAME).so; \
	SHLIB_SUFFIX=; \
	ALLSYMSFLAGS='-Wl,--whole-archive'; \
	NOALLSYMSFLAGS='-Wl,--no-whole-archive'; \
	SHAREDFLAGS="$(CFLAGS) $(SHARED_LDFLAGS) -shared -Wl,-install_name,$$SHLIB$$SHLIB_SOVER$$SHLIB_SUFFIX"

3. Create Makefile

./Configure shared android

4. Remove '''CFLAG''' option '''-mandroid''' from Makefile

5. Build
   make CALC_VERSIONS="SHLIB_COMPAT=; SHLIB_SOVER="

Resulting error: syntax error near unexpected token `;'

I think there is something still wrong with my -install_name syntax? How do you build OpenSSL on macOS?

I need to build boih arm7 and x86 so I can test in Genymotion emulator.

@ekke @mabedMRD @alexgarret @machinekoder Qt guys? Any tips or suggestions are greatly appreciated.

I found a solution that works for building OpenSSL on Arm, Arm7, x86, on macOS. You just have to use Android NDK r10e or earlier.

[ekke]

good to hear that you found a solution.
BTW: I'm only developing on macOS, allways using NDK r10e. Never tried x86.

[esutton]

I am developing Android and iOS on macOS using Qt C++ and React Native. React Native requires r10 e. I plan to stick with r10e. Until I have reason to not use it.

x86 build make it quick and easy to debug using Android x86 emulators such as Genymotion. I only tried Ubuntu because I was desperate and suspected the OpenSSL build could have been failing on macOS because of a clang issue. I do not know cause. But r10e just works.
