Unordered_map declaration throws error with NDK (clang), works fine with gcc

I'm trying to run a C++ project on Android. The following statement appears in one of the source files (part of a big project).
std::unordered_map <int, std::shared_ptr<Frame>, std::hash<int>, std::equal_to<int>,
Eigen::aligned_allocator< std::pair<const int, std::shared_ptr<Frame> > > > idToKeyFrame;
The NDK build complains the following
sysroot/usr/include/c++/v1/unordered_map:1684:5: error: static_assert failed due to requirement 'is_same<value_type, typename allocator_type::value_type>::value' "Invalid allocator::value_type"
I cannot spot what part of declaration is incompatible. Please help in fixing this error.

Update
When I modify the allocator (as suggested in comment by Marc) to Eigen::aligned_allocator<std::pair<int, std::shared_ptr<Frame>>> The error message remains the same but line number changes
sysroot/usr/include/c++/v1/unordered_map:854:5: error: static_assert failed due to requirement 'is_same<value_type, typename allocator_type::value_type>::value' "Invalid allocator::value_type"
Update++
According to this answer :
libstdc++ does not static_assert, libstdc++ ignores the exact type of the allocator and rebinds it to the container's value type.
and
Clang/libc++ are not forgiving
Yet another Update
I have been able to go past the error by commenting out the line in the source for unordered_map. This is a resort for now (until I get a solution).

How to get the full information of runtime error instead of <Timeout exceeded getting exception details>?

So I'm trying out xamarin in VS2017, but found this undhandled error:
Unhandled Exception:
Java.Lang.SecurityException: <Timeout exceeded getting exception details>
This is very clueless. How can I get the full information of the runtime error like in Android Studio?

I had the same problem while calling some native API,
solved it by
Put a try catch around the block of got which is throwing the error.
Put a breakpoint in the catch block, you can get actual details of the exception.

After getting assistance from Microsoft, I finally found the solution.
TL;DR
Use VS Android device log and filter with "mono-rt" or "Error"
Complete Answer:
There are 2 solution:
1. Using Android Studio logcat:
Open the Android Studio logcat (View > Tool Windows > Logcat). From the logcat window, choose the device, choose the Xamarin.Android deployed application, and choose logcat for Error
Android logcat will display the runtime error:
2. Using Visual Studio Android Device Log:
Open the Visual Studio Android Device Log(Tools > Android > Device Log).
Here is the tricky bit: Unlike Android Studio, VS list all of the device log, not limited to the Xamarin.Android app deployed. So somehow we have to use the filter to get the relevant information. The problem is, what filter should we use? I used my application name and the error didn't show up. It turns out that when the error happen, the log doesn't contain any of the application name. Instead it has "mono-rt" tag with "Error" type.
So there you have it. Filter it with "mono-rt" tag or "Error" type and you will find the error information

Error building openframeworks for android: “ invalid use of incomplete type ‘class Poco::Path’”

I am trying to build an android application with OF. The application runs in two other computers. However, it does not work on mine. I am using a mac.
I run the command "make AndroidDebug" in the project folder, and this is the error I have:
/Library/openFrameworks/addons/ofxHTTP/libs/ofxHTTP/src/PostRouteFileHandler.cpp:98:46: error: invalid use of incomplete type 'class Poco::Path'
ss << Poco::Path(formFileName).getExtension();
I have installed poco, but nothing changes afterwards.
What can I do to solve this?
Thanks

Have you included Poco/Path.h?
A forward declaration might appeared earlier (possibly in another header) without complete definition.

Error while trying to apportable iOS app to Android

I have been trying to port my first iOS app to Android with apportable.
I have solved alot of warnings and errors but cannot get rid of this last one.
The App I made is a fitness application for jogging so it uses CoreLocation.
Everything looks good when I run apportable now except this last error:
Build/android-armeabi-debug/com.apptonix.easyrunner/testTabbedWithCore/libtestTabbedWithCore.a(DetailViewController.m.o):/Users/peterbodlund/Documents/xcodeprojects/Training/inlamning5/testTabbedWithCore/testTabbedWithCore/DetailViewController.m:function L_OBJC_CLASSLIST_REFERENCES_$_114: error: undefined reference to 'OBJC_CLASS_$_MKPinAnnotationView'
scons: * [Build/android-armeabi-debug/EasyRunner/apk/lib/armeabi/libverde.so] Error 1
scons: building terminated because of errors.
Exception AttributeError: "'NoneType' object has no attribute 'pack'" in > ignored

Usually this is an indicator that there were link errors. Check your output higher up and look for missing symbol errors.
The build log is confusing because the build is parallel by default.
Add the option -j1 to cause the build to stop immediately after the first error.

Android hprov-dump giving me Error: expecting 1.0.3

I've used the Dump HPROF File option in eclipses DDMS and made my hprof file called in.hprof, but when I try to do the hprov-conf in.hprof out.hprof from the command line it gives me the error "Error: expecting 1.0.3". Any ideas?

Never found out why it was giving me the error, but instead of trying to convert it and open it in the external MAT I ended up using the built in tool for Eclipse which worked perfectly and is much simpler. One click instead of exporting, converting and opening in a different window.
