SFML for android Gradle Build Fails
« on: October 12, 2018, 11:12:12 pm »
I'm using NDK r18, SFML 2.5, Android API 24, Clang on MacOSX. STL=c++_shared.

And I made sure the STL value was the same across cmake and the generated makefiles.

I followed both the SFML official guide and a template found here on the forums. Both end with the same error. I'll show the command line example from the official guide only:

Here is the output

Error: undefined reference to 'sf::String::String(char const*, std::__ndk1::locale const&)'

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

Here is the makefile

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE    := sfml-example

LOCAL_SRC_FILES := main.cpp

LOCAL_SHARED_LIBRARIES := sfml-activity
LOCAL_SHARED_LIBRARIES += sfml-graphics
LOCAL_SHARED_LIBRARIES += sfml-window
LOCAL_SHARED_LIBRARIES += sfml-audio
LOCAL_SHARED_LIBRARIES += sfml-network
LOCAL_SHARED_LIBRARIES += sfml-system
LOCAL_SHARED_LIBRARIES += openal

LOCAL_WHOLE_STATIC_LIBRARIES := sfml-main

include $(BUILD_SHARED_LIBRARY)

$(call import-add-path,/Users/maverick/Library/Android/ndk/sources)
$(call import-module,third_party/sfml)
 

Someone on IRC said it might be link order so I've tried every possible combination. And I know it has to be a specific order: dependent libraries first so graphics then window then audio/network then system. As you can see I have that too.

I tried static and it installed but crashed on startup. Reading the official android C++ docs, they mention static is not suggested and use shared instead.

Help me get this to build and run right on android.
