hey I am new to Qt..
I am trying to study a program used to render font outlines using freetype2.
I am getting following error:

Qt Code: 
  1. (.bss+0x0):-1: error: multiple definition of `g_usageText'
  2. (.bss+0x0):-1: error: first defined here
  3. (.bss+0x0):-1: error: multiple definition of `g_usageText'
  4. (.bss+0x0):-1: error: first defined here
  5. :-1: error: collect2: ld returned 1 exit status
To copy to clipboard, switch view to plain text mode 


my .pro file is:

Qt Code: 
  1. QT       += core gui
  2.  
  3. TARGET = 2_sept_app1
  4. TEMPLATE = app
  5.  
  6. SOURCES += main.cpp\
  7.         widget.cpp
  8. MOC_DIR = ./moc
  9. LIBS += -lz -lfreetype
  10. INCLUDEPATH += $$MOC_DIR \
  11.         /usr/include/freetype2 \
  12.         /usr/lib
  13. HEADERS  += widget.h
To copy to clipboard, switch view to plain text mode 

I searched on Google and modified .pro file with that 'MOC_DIR' entries....but still problem persists

how do I solve this problem?
