this java file converter.java http://pastebin.com/vnnpy7d5

thanks guys :)

if counted right this

ibhome3 = (button) findviewbyid(r.id.ibhome3);

is causing problem. have imagebutton in xml button in java declaration. change 

imagebutton ibhome3;

about logcat

also, little advice on logcat. if find first line says caused by after fatal exception can track down problem easier. here 

 caused by: java.lang.classcastexception: android.widget.imagebutton cannot cast android.widget.button

this gives exception

java.lang.classcastexception

then find first line after references package. here 

at com.jumoun.itemp.converter.oncreate(converter.java:41)

this tells problem starts in converter.java @ line 41

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).
