Well, looks like I'm going to continue this long monologue. I got my access to
a mips-irix6.5 back, and it's still failling:

$ ../gcc/configure --prefix=/tmp/debug/irun --enable-languages=c,fortran
--with-gmp=$HOME/gfortran/gfortran_libs/mips-irix
--with-mpfr=$HOME/gfortran/gfortran_libs/mips-irix
--with-as=$HOME/gfortran/gfortran_libs/mips-irix/bin/as
--with-ld=$HOME/gfortran/gfortran_libs/mips-irix/bin/ld --disable-libssp
--disable-libmudflap

[configure works fine]

$ gmake
[... works fine until ...]
gmake[3]: Entering directory `/tmp/debug/ibin/mips-sgi-irix6.5/libgfortran'

I have no idea what is going on here.

[wilson at gcc dot gnu dot org]

------- Comment #7 from wilson at gcc dot gnu dot org  2005-10-23 21:27 -------
I would guess a GNU make bug.  What version of GNU make are you using?  Try a
newer release.

Alternatively, this could be a shell bug.  What shell and version are you
using?  Try using a different shell and/or a more recent shell version. 
Preferably a recent version of bash.

There should be a "gmake all-am" line right before the failure.  The
libgfortran all rule does a recursive make, and it appears that the value of
CC, which is $(CC_FOR_TARGET) is getting clobbered somehow by this recursive
make invocation.  It was OK before this recursive make, because there are some
rules invoked before the recursive make, and they didn't fail for you.

I had GNU Make version 3.78.1, which seems too old. 3.80 works fine. But...
later I have the following failures:

I'm investigating. For now, all I can say is I *hate* C99.

[Bug libfortran/22097] libgfortran build failure on mips-sgi-irix6.5

[fxcoudert at gcc dot gnu dot org]

------- Comment #9 from fxcoudert at gcc dot gnu dot org  2005-11-10 15:35 -------
On mips-irix6.5, the libgfortran config.h contains:
#define HAVE_CABSF 1
and
/* #undef HAVE_COMPLEX_H */

and in math.h it does have the following:

struct __cabsl_s { long double a,b; };
extern long double cabsl( struct __cabsl_s );

while the correct definition of cabsl is provided in complex.h. I don't know
why on earth all this is happening, but I guess the root of the problem is
that:

$ cat a.c
#include <math.h>
#include <stdio.h>

int main (void)
{
  long double __complex__ z;

  printf ("%Lg\n", cabsl(z));
  return 0;
}
$ ./bin/gcc -std=c99 a.c
a.c: In function 'main':
a.c:8: error: incompatible type for argument 1 of 'cabsl'

while the cabsl man page clearly states that cabsl is to be found in <math.h>.
I'd like to have the opinion of mips-irix experts here: should the above code
compile fine? what is the right way of doing things here?

Moving to "target" component. This bug is still present and it prevents
building gfortran on mips-sgi-irix6.5.

I am not (though it shouldn't take too much time, I'm positively squashed under
real life work). And, IIRC, the mips maintainers don't have access to IRIX any
more. So, if you want to submit something for this, please do!

Subject: Re:  libgfortran build failure on mips-sgi-irix6.5

Okay, I will try!

Is there a preprocessor macro defined, which identifies IRIX?

As I see, there are two macros which are candidates IMHO:

_SGI_SOURCE
sgi, __sgi, __sgi__

any hints?

Created an attachment (id=10794)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=10794&action=view)
fixes bootstrap failure in ligfortran/instrisics/c99_functions.c for
mips-sgi-irix6.5

It's similiar as http://gcc.gnu.org/ml/gcc-patches/2005-12/msg01578.html
There is one open question. Is the "#ifdef __sgi__" the right way to
distinguish between IRIX and other mips systems?
This patch applies cleanly to 4.1 and mainline.
I ask for comments.

Looking at config.guess and other occurences of __sgi__ in the gcc source, I
think it's the right way.

Submit the patch on the gcc, gcc-patches and fortran along with the question,
and if there is no objection from the mips maintainers in the next few days,
I'll approve it.

Thanks for the patch!
