Barry is correct. I wanted to note that this is fixed in petsc-dev.<br><br> Matt<br><br><div class="gmail_quote">On Fri, Sep 18, 2009 at 4:21 AM, David Colignon <span dir="ltr"><<a href="mailto:David.Colignon@ulg.ac.be">David.Colignon@ulg.ac.be</a>></span> wrote:<br>

<br>
I already have had the same kind of problem and here is the answer I got from Barry Smith :<br>
<br>
<br>
This happens because the BuildSystem inherits the bad feature of autoconf that checks for functions<br>
using the C compiler even when the C++ compiler will be used to actually compile the package.<br>
<br>
Edit $PETSC_ARCH/include/petscconf.h and remove the lines<br>
<br>
<br>
#ifndef PETSC_HAVE_ISINF<br>
#define PETSC_HAVE_ISINF 1<br>
#endif<br>
<br>
<br>
#ifndef PETSC_HAVE_ISNAN<br>
#define PETSC_HAVE_ISNAN 1<br>
#endif<br>
<br>
DO NOT rerun config/configure.py just do the make all again.<br>

Hi,<br>
<br>
I am trying to compile petsc on snow leopard. I need to have complex support and support for C++. I am using the gcc and g++ compilers that come packaged with the developers tools<br>
<br>
i686-apple-darwin10-gcc-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5646)<br>
Copyright (C) 2007 Free Software Foundation, Inc.<br>
This is free software; see the source for copying conditions. There is NO<br>
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.<br>
<br>
and the gfortran compiler from <a href="http://hpc.sourceforge.net/" target="_blank">http://hpc.sourceforge.net/</a>. The configuration file I am using is<br>
<br>
#!/usr/bin/env python<br>
<br>
configure_options = [<br>
'--FFLAGS=-m64',<br>
'--CFLAGS=-m64',<br>
'--CXXFLAGS=-m64',<br>
'--LDFLAGS=-L/usr/lib',<br>
'--with-python=0',<br>
'--with-shared=0',<br>
'--with-dynamic=0',<br>
'--with-mpi-dir=/Users/nmoran/local/openmpi',<br>
'--with-clanguage=C++',<br>
'--with-scalar-type=complex',<br>
'--with-debugging=yes',<br>
'--with-gcov=0'<br>
]<br>
<br>
if __name__ == '__main__':<br>
import sys,os<br>
sys.path.insert(0,os.path.abspath('config'))<br>
import configure<br>
configure.petsc_configure(configure_options)<br>
<br>
<br>
I am getting errors that the macros isinf and isnan cannot be found in the scope for various files. The first one listed is src/sys/ftn-custom/zutils.c on the lines<br>
<br>
return (PetscTruth) PetscIsInfOrNanScalar(*v);<br>
and<br>
return (PetscTruth) PetscIsInfOrNanReal(*v);<br>
<br>
These macros are defined in /usr/include/architecture/i386/math.h. No errors are found if scalar-type is real. It seems the #include<complex> somehow undefines these macros. I have got petsc to compile by redefining these macros at the top of each of the problem files but this is not a very elegant solution.<br>
<br>
Regards.<br>
<br>
Niall.<br>
