PONew to C/C++ Using Android NDK to port Legacy code, getting compile errors
text
Body
copied!<p>I have been trying to take some old Symbian C++ code over to Android today using the NDK.</p> <p>I have little to no C or C++ knowledge so its been a chore, however has to be done.</p> <p>My main issue is that I'm having trouble porting what I believe is Symbian specifi code to work using the small C/C++ subset that is available with the Android NDK.</p> <p>Here is a picture of the compilation errors I'm getting using cygwin</p> <p>I was wondering if anyone could point me in the right direction on how to deal with these errors? For instance is TBool/Int/TUint/RPointerArray/RSocket a Symbian primitive and thats why it wont compile or is it something else?</p> <p>Also what is ISO C++?</p> <p>Any tutorials, guides or tips and help would be greatly appreciated.</p> <p>EDIT:</p> <p>Here is a code snippet from the .h file I am trying to import followed by the output for the snippet from the compiler.</p> <p>Could someone guide me on how I would port this Symbian specific code to normal C++? </p> <p>If I got an idea of whats Symbian specific and how to change it I believe I could change then begin to port the rest myself</p> <hr> <pre><code>#ifndef __RTPSTREAM_H__ #define __RTPSTREAM_H__ class CRTPParser; class MDataRecorderObserver { public: virtual void DataRecorded(const TDesC8& aData, TUint aCodec, TUint aFramesizeMs)=0; }; class MRTPStreamDataObserver { public: virtual void AudioDataSent()=0; virtual void DataReceived(const TDesC8& aData,TUint aCodec, TBool aMarker, TUint aSeq, TUint aTime)=0; virtual void DataReceived(const TDesC8& aData)=0; }; </code></pre> <hr> <pre><code>$ make APP=ndk-socket Android NDK: Building for application 'ndk-socket' Compile++ thumb: socket <= apps/ndk-socket/project/jni/rtpstream.cpp In file included from apps/ndk-socket/project/jni/com_ciceronetworks_utils_RTPJn i.h:2, from apps/ndk-socket/project/jni/rtpstream.cpp:4: build/platforms/android-3/arch-arm/usr/include/jni.h:489: note: the mangling of 'va_list' has changed in GCC 4.4 In file included from apps/ndk-socket/project/jni/rtpstream.cpp:11: apps/ndk-socket/project/jni/rtp/RTPStream.h:15: error: ISO C++ forbids declarati on of 'TDesC8' with no type apps/ndk-socket/project/jni/rtp/RTPStream.h:15: error: expected ',' or '...' bef ore '&' token apps/ndk-socket/project/jni/rtp/RTPStream.h:23: error: ISO C++ forbids declarati on of 'TDesC8' with no type apps/ndk-socket/project/jni/rtp/RTPStream.h:23: error: expected ',' or '...' bef ore '&' token apps/ndk-socket/project/jni/rtp/RTPStream.h:24: error: ISO C++ forbids declarati on of 'TDesC8' with no type apps/ndk-socket/project/jni/rtp/RTPStream.h:24: error: expected ',' or '...' bef ore '&' token apps/ndk-socket/project/jni/rtp/RTPStream.h:24: error: 'virtual void MRTPStreamD ataObserver::DataReceived(int)' cannot be overloaded apps/ndk-socket/project/jni/rtp/RTPStream.h:23: error: with 'virtual void MRTPSt reamDataObserver::DataReceived(int)' apps/ndk-socket/project/jni/rtp/RTPStream.h:30: error: 'TInt' has not been deca red </code></pre>
