             Bug #: 14326
           Summary: Cannot link to etext symbol in scripttempl/pe.sc
           Product: binutils
           Version: 2.22
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ld
        AssignedTo: address@hidden
        ReportedBy: address@hidden
    Classification: Unclassified


For the following main.cpp

#include <iostream>
using namespace std;
extern int etext;
int main(void)
{
    cout << (int*) &etext << endl;
      return 0;
}


compiling:

$ i686-w64-mingw32-g++ main.cpp -Wl,-verbose  | grep PROVIDE
    PROVIDE (etext = .);
    PROVIDE (end = .);
    PROVIDE ( _end = .);
/tmp/ccVghwrB.o:main.cpp:(.text+0x3fb): undefined reference to `etext'
collect2: error: ld returned 1 exit status

$ x86_64-w64-mingw32-g++ main.cpp -Wl,-verbose  | grep PROVIDE
    PROVIDE (etext = .);
    PROVIDE (end = .);
    PROVIDE ( _end = .);
$ 



so i686-w64-mingw32-g++ fails to link etext. I'm not sure what's the problem
exactly. Here is the a part of irc chat with ktietz on #mingw-w64:



<kkimlabs_> then do you think it's a bug?
<ktietz> it is a bug in i686's pe.sc
<ktietz> the symbol exported there has to be _etext, too
<ktietz> as a C symbol for 32-bit has to have an leading underscore, but pe.sc
(from binutils' ld) just provides symbol 'etext'.  So it is unreachable
<ktietz> btw for 64-bit it works, as here no underscore as prefixed for C
symbols
<ktietz> kkimlabs_ file a bug for it to binutils' bugzilla and add me to it CC
