If you downloaded a pre-compiled version of XBeach, you can skip this entire step.XBeach is written in Fortran and can be compiled on either a 32-bit Windows system or a UNIX system.
XBeach is tested with two compilers on the following platforms: Windows XP 32-bit with the Intel Fortran compiler CentOS Linux (similar to Red Hat Linux) with the Intel Fortran or GFortran compiler Other Windows and Linux platforms may not pose any problems, but it hasnt been tested officially yet. If you experience any problems on other Windows of Linux platforms, please describe the problem in the Compiling XBeach forum in the Forum page and we will try to help you out. Other compilers may pose problems and are not supported for now. Fortran Compiler Software Development SuitesUse the Intel Fortran compiler If you use the Intel Fortran compiler, the easiest way is to use this compiler from either the Visual Fortran or the Visual Studio 2008 (see figure) software development suites. You can open the corresponding project files in the trunk or the trunkVS2008 directory and compile the entire project after selecting the right build (MPI, netCDF, debug, etc.) compiletest0 Use the GFortran compiler From the UNIX command line, go to the trunk directory of the XBeach source code location. You can now compile XBeach by issuing the following commands: compilecode1. In fact, XBeach is always compiled as library, possibly with a wrapper binary calling this library. Fortran Compiler How To Deal WithSee the following examples on how to deal with this new program structure and the GFortran compiler. Havent tried the gccg compilers I built, just used the system ones. However, I failed to get this to compile SciPy, and later saw in SciPys README that it is known to generate buggy scipy binaries. They provide instructions and a script for Building a Universal Compiler, but, again, this hasnt been updated for Mountain Lion yet. So, if I was to build dynamic libraries made with GCCs gfortran v4.6, could they then be linked with C code compiled by Xcodes native compiler At a minimum, I figure resulting Mach-O binaries need both x8664 and i386 code paths. Do GCC provide backwards compatibility with Apples (forks of) GCC I know gfortran has the -ff2c flag, but is this stable across versions. I had been including the flags -arch x8664 -arch i386 in both CFLAGS and FFLAGS environment variables on earlier OSX versions (Snow Leopard to Lion). Pythons distutils, and probably other OSX compilers, expect these flags to work, when configured to build apps or frameworks, using Xcodes universal SDK. Even Intel are still having problems integrating ifort into Xcode 4.4, so this is not something I expect to work. Im in the process of writing a build script to get this to work. Unfortunately, Ive had to apply a couple of patches, and learn about the Apple way of building GNU software. Any reasons why it shouldnt be Ill update with an answer if I get it to work. First time it said that only apps from App Store can be installed. After installing gfortran, python setup.py build and python setup.py install worked fine. ![]() I dont have that gfortran; the Xcode I have (4.5) only came with OSX SDKs 10.7 and 10.8 (Lion and Mountain Lion). The compiler that came with Xcode was built for Lion - the target (from gcc -v ) is i686-apple-darwin11. I do have the command line tools installed btw (as also described in the link from 2nd line of question), but have started using GCC4.7 from MacPorts, as it compiles faster code than Apples quite ancient GCC4.2, as well as clang, according to some ATLAS and numpy benchmarks I ran. ![]() This seems to be working okay now - Ive successfully compiled x86-64 and i386i686 LAPACK, ATLAS and BLAS fortran libraries - but there are some ranlib tests which fail, when running make -k test in the build directories. I could provide more info on that pastebin or somewhere, if someone wants.). The build takes about 30-60 minutes on my quad-core 2.8GHz Mac Pro, and became quite an involved process, so I wrote a set of build scripts for it, which Ive shared at github.com. You can test installname s with otool -L filename (more info on the reasons for this is here ). There were only minor changes between 4.2.1 and 4.2.4, and the build scripts include the patches needed to upgrade the code. I mostly copied code from the buildllvm and buildgcc bash scripts provided with Apples llvmgcc42, but had some of it had to be modified, including a few lipo and installnametool commands. I thought this should work just byadding fortran to the LANGUAGES variable in buildgcc. Ive had to use clang and clang as CC compilers, or else I get EXCBADACCESS malloc errors.
