[Android-development] Fwd: OpenSSL Runtime Support

[Robert Iakobashvili]

Hello,
I'd like to make my Qt-5 application for Android
working with openssl.

So, I'm following QT5 Android wiki as below:
http://qt-project.org/wiki/Qt5ForAndroid and by using
git version since June 21, 2013

To enable run-time support and usage for openssl
related functions in my application, I've configured it
with added flags -openssl and -I/path-to-openssl-headers.

./configure -developer-build -xplatform android-g++ -nomake tests
-nomake examples -android-ndk /home/robert/dev/android-ndk-r8e-ma
-android-sdk /home/robert/dev/android-sdk-linux -android-ndk-host
linux-x86 -skip qttranslations -skip qtwebkit -skip qtserialport -skip
qtwebkit-examples -openssl -I/home/robert/dev/openssl-1.0.1e/include

and seen that openssl run-time support is configured

Trying to make, I'm getting the following compilation error:

ssl/qsslsocket_openssl_symbols.cpp: In function 'QStringList libraryPathList()':
ssl/qsslsocket_openssl_symbols.cpp:426:52: error: 'dl_iterate_phdr'
was not declared in this scope

When looking at link.h header file in
android-ndk-r8e-ma/platforms/android-9/arch-arm/usr/include

the following declarations are in use in link.h:

#ifdef __arm__
typedef long unsigned int* _Unwind_Ptr;
_Unwind_Ptr dl_unwind_find_exidx(_Unwind_Ptr pc, int* pcount);
#else
int dl_iterate_phdr(int (*cb)(struct dl_phdr_info*, size_t, void*), void*);
#endif

and instead of dl_iterate_phdr used for __arm__
dl_unwind_find_exidx

Does it mean that I need to patch ssl/qsslsocket_openssl_symbols.cpp
for __arm__ builds or there's another more conventional way to enable
run-time support for openssl on Android?

Sorry for the newbie question and for my limited understanding.

Thank you in advance!

Robert
