Can you please show
  - the source code passed to gperf?
  - the version number of gperf being used to generate the processed file?
  - the processed file?
  - the source code of the source file that #includes the processed file?
  - the gcc command line that compile that compilation unit?
  - the output of
       $ nm --dynamic .libs/libwebkit-1.0.so | grep findEntity

I'm asking because
  - it could be that you are using a gperf version older than 3.0.3,
  - it could be that the functions are compiled as C functions and you
    refer to them from C++ without 'extern "C"' declarations.
  - if it's a problem in gperf, please provide a small reproducible test case.
