[LLVMdev] File reading in LLVM 2.8

[Abhirup Ghosh]

Hi,
     I am new to LLVM. I am trying to read a plain text file in a llvm
pass. But getting an error -

llvm[0]: Linking Release Loadable Module LLVMHello.so
/usr/bin/ld: /home/abhirup/llvm/llvm2.8_Install/llvm-2.8/lib/Transforms/Hello/Release/Hello.o:
relocation R_X86_64_PC32 against undefined symbol `(anonymous
namespace)::Hello::update_sec_read(char const*)' can not be used when
making a shared object; recompile with -fPIC
/usr/bin/ld: final link failed: Bad value
collect2: ld returned 1 exit status

I have used simple ifstream code -

void update_sec_read (const char* Filename)
{
  std::ifstream In(Filename);
  if (!In.good()) {
    errs() << "couldn't load file '" << Filename << "'!\n";
    return;
  }
  while (In) {
  }
}


Can anyone please help me out?
