[Bug fortran/33281] New: gfortran crt2.o not found under Vista

[DHConsultancy at skynet dot be]

I'm trying to run gfortran under Windows Vista. I ran into "ld: crt2.o: No such
file". I've found several reports on this, but no solution... Is there a
solution available already?

Do you compile yourself or use pre-made binaries (and which binaries)? What
version of gfortran do you use? If you build the compiler yourself, do you use
cygwin or mingw?

What does the compiler say when you add the -v flag? ("gfortran -v myfile.f90")
What is the value of your PATH environment variable?

The solution is to build gcc/gfortran wiith -D__USE_MINGW_ACCESS in CFLAGS;
>From mingw/include/io.h

/* Some defines for _access nAccessMode (MS doesn't define them, but
 * it doesn't seem to hurt to add them). */
#define F_OK    0       /* Check for file existence */
/* Well maybe it does hurt.  On newer versions of MSVCRT, an access mode
   of 1 causes invalid parameter error. */   
#define X_OK    1       /* MS access() doesn't check for execute permission. */
#define W_OK    2       /* Check for write permission */
#define R_OK    4       /* Check for read permission */


and later:
#ifdef __USE_MINGW_ACCESS
/*  Old versions of MSVCRT access() just ignored X_OK, while the version
    shipped with Vista, returns an error code.  This will restore the
    old behaviour  */
static inline int __mingw_access (const char* __fname, int __mode)
  { return  _access (__fname, __mode & ~X_OK); }
#define access(__f,__m)  __mingw_access (__f, __m)
#endif

I use the binaries for version 4.2.2, native Windows version, from
http://gcc.gnu.org/wiki/GFortranBinaries

the compilation works fine, the error occurs at the link phase:
" ld: crt2.o: No such file: No such file or directory"

I was hoping to avoid having to do the build. If all else fails, I'll 
try it.

Thnx for your help.

It might be worth putting into the tree. Danny, would you be OK with the

Daniel,

Can you try the updated binaries at
http://quatramaran.ens.fr/~coudert/gfortran/gfortran-windows.exe ? They are
built with the patch in comment #5.

> Fix committed to mainline.

As a MinGW administrator, I am dismayed that you consider this
__USE_MINGW_ACCESS kludge as a solution to this bug; I would like this
particularly nasty kludge to go away, from the MinGW code base, as soon as is
practicably possible.

My own view on this is, that since X_OK has no meaning on any platform
supported by MinGW, our headers simply should not define it.  Danny Smith has
advised me that I cannot do that, since GCC needs it, if I don't define it, GCC
will give an arbitrary value of one, which will simply reintroduce the old
broken behaviour; IMO, that is wrong: if I don't define it, then it is because
it should not be used, and GCC should respect that.

Danny has further advised me that, if I were to adopt the next best compromise,
and define X_OK with a value of zero, that that too would break GCC, because it
uses X_OK in other contexts than the mode argument to access(), and in those
contexts the value of zero would not work.  If this is indeed the case, then I
would respectfully suggest that such usage is a violation of IEEE-1003.1, which
explicitly defines F_OK, R_OK, W_OK and X_OK for use as values for composing
the mode argument to access(), (and for no other purpose).

Regards,
Keith.

You're welcome to contribute and provide a patch that implements your idea of
what would we the Right Thing To Do, as long as it doesn't break support of
existing MinGW versions. Post your patch to the gcc-patches mailing-list and it
will be reviewed.

Thanks for helping,
FX
