title: Porting to AIX 6.1 (ld: 0711-317 ERROR: Undefined symbol) with Xerces
body: <h1>AIX 6.1</h1>
  
  <p>Porting an application from AIX 5.3 to AIX 6.1, Where it is building successfully in AIX 5.3. 
  I am getting following errors while trying to build the same in 6.1.</p>
  
  <ol>
  <li>Able to compile and create libraries from C and C++ source code</li>
  <li>While trying to create a run time executable by using libraries the following error occurs</li>
  </ol>
  
  <h1>Observations</h1>
  
  <p>Following errros are seems to be while trying call functions from the "libdocxml.a" library, which built successfully with xlC compiler earlier.</p>
  
  <p>Compiler used: xlC_r, same compiler used for building all the libraries and application.</p>
  
  <h2>NOTE:</h2>
  
  <p>Executables are building properly in 5.3 refering to this library.
  But the same in 6.1 is giving above errors.</p>
  
  <p>This library is related with xml parsers (xercesparser: XML4C and Xerces-C) </p>
  
  <p>Please go through the end of the following error description. Actual errors are defined at the end. </p>
  
  <p>Any help would be highly appreciated. Thanks in advance.</p>
