maifestfile code is

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.archifiles.pointpakistan" android:versioncode="1" android:versionname="1.0" >  <uses-sdk     android:minsdkversion="10"     android:targetsdkversion="10" />  <permission     android:name="com.archifiles.pointpakistan.permission.maps_receive"     android:protectionlevel="signature" />  <uses-feature     android:glesversion="0x00020000"     android:required="true" />  <uses-permission android:name="com.archifiles.pointpakistan.permission.maps_receive" /> <uses-permission android:name="android.permission.internet" /> <uses-permission android:name="android.permission.write_external_storage" /> <uses-permission android:name="com.google.android.providers.gsf.permission.read_gservices" /> <uses-permission android:name="android.permission.access_coarse_location" /> <uses-permission android:name="android.permission.access_fine_location" />  <application     android:allowbackup="true"     android:icon="@drawable/ic_launcher"     android:label="@string/app_name"     android:theme="@style/apptheme" >     <activity         android:name="com.archifiles.pointpakistan.splashscreenactivity"         android:label="@string/app_name" >         <intent-filter>             <action android:name="android.intent.action.main" />              <category android:name="android.intent.category.launcher" />         </intent-filter>     </activity>     <activity android:name=".mainactivity"></activity>     <activity android:name=".poiactivity"></activity>     <activity android:name=".showmapactivity"></activity>      <meta-data         android:name="com.google.android.maps.v2.api_key"         android:value="aizasyde_pk7x98rwq2gtkaauuv0k0yri3trpua" />      <uses-library      android:name="com.google.android.maps"      android:required="true" />   </application>

layout file code

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".mainactivity" >  <fragment     android:id="@+id/map"     android:layout_width="match_parent"     android:layout_height="match_parent"     class="com.google.android.gms.maps.supportmapfragment" />  </relativelayout>

no log traces available in log cat.

actually used supportmapfragment. like

supportmapfragment gm;    gm = ((supportmapfragment)(getsupportfragmentmanager().findfragmentbyid(r.id.map))).getmap();

so in xml file must use 

      <fragment         android:id="@+id/map"       android:name="com.google.android.gms.maps.supportmapfragment"       />

hope work.

remove below line in manifest

<uses-library    android:name="com.google.android.maps"    android:required="true" />

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
