Reversed it to use gcc/g++ as the default C and CXX compilers for Darwin 10.X
systems.
Tested: duck (darwin 11), wren (darwin 12) and fred (darwin 10).
Use Clang as the compiler for the Mac platform.
Changed all Mac to use clang/clang++ as the default C and CXX compilers if
not provided by the user. Still use gfortran as the default fortran
compiler since Apple does not provide any fortran compiler.
Tested: passed all three macs OS, snow leapord (fred), lion (duck) and
mountain lion (wren). Also passed test using Apple gcc, Gnu gcc, Intel
as the C compilers and all corresponding CXX compilers fits in.
Did not run h5committest or other non-mac platform since this change
affect Apple platforms only.
Fixes for HDF5 1.8.10 p1
HDFFV-7975
Changed the max single I/O operation size on Darwin/Mac OS X.
HDFFV-8124 and HDFFV-8158
Fixed a core VFD bug when large blocks of data are read.
HDFFV-8246
Added more fields to the VFD read/write error messages.
Tested on:
64-bit Windows 7, Visual Studio 2010, CMake
64-bit Mac OS X Snow Leopard (Fred), Fortran, C++
64-bit BE Linux (Ostrich), Fortran, C++
32-bit LE Linux (jam), Fortran, C++ (also parallel w/ Fortran)
dt_arith would fail in Lion and Mountain Lion system when GCC version 4.2.1
is used with --enable-production. Somehow the -O optimization will fail some of
the hard conversion code.
Solution:
This is just a temporary patch by detecting if this is a Lion or Mountain Lion
system using GCC 4.2.1, then just remove the any -O option from the PROD_CFLAGS.
A better fix should be deviced later.
Tested: Duck(lion) and Owl (mountain lion) tested with --enable-production.
Also tested in Fred and Tejeda, both Snow Leopard systems to verify there is
no undesired side effect.
Description: The Fortran compiler flags were all set to "-O". They should be
different setting for different situations. E.g, "-g" for debug and
"-pg" for profile, etc.
Fix: set them to appropriate different values.
Tested: in Remote ADA AIX machines using 3 different settings:
configure --enable-fortran --enable-cxx # default to --disable-production
configure --enable-fortran --enable-cxx --enable-production
configure --enable-fortran --enable-cxx --disable-production
