There are a number of barriers to building ASCEND on 64-bit Windows:

We are working towards fixing these items.

Steps to date:

  • install MSYS bundle to c:\msys as instructed here
  • install MinGW-64 bundle to c:\mingw64 as instructed (we used mingw-w64-bin_i686-mingw_20111220.zip
  • install 64-bit Python 2.7.2
  • append /c/Python27 and /c/Python27/Scripts to the PATH in MSYS.
  • download and extract source tarball for SCons 1.2.0. Build via python setup.py bdist_wininst then install resulting .exe in dist subfolder.
  • create 'scons' file in c:\Python27\Scripts containing
#!/bin/sh
python /c/Python27/Scripts/scons.py $*
  • svn checkout ASCEND source code (from trunk)
  • scons

For CUnit

  • use SVN trunk code
  • ./configure --prefix=/mingw --host=x86_64-w64-mingw32 --build=mingw32
  • make install

For SUNDIALS (used by the IDA solver):

  • ./configure --host=x86_64-w64-mingw --prefix=/mingw
  • make -j4
  • make install

GDB

Test suite

  • The CUnit test suites seem to be basically working.
  • Suite 'utilities_ascEnvVar' current crashing.

Python bindings

  • Installed SWIG 1.3.40
  • Seems to be an issue with linking to python27.lib. The problem may be that described here, or it could be a 64-bit specific problem (or both). Perhaps we should try what happens with Python 2.5 alternatively.

Things we need to work on:

  • A lot of new compiler warnings due to the very new GCC version used by MinGW-64 that will need to be worked through.
  • Installing the MinGW-64 toolchain with 'standard' (local) tool filenames (maybe a quick script to rename or symlink them?)
  • Detecting 32-bit vs 64-bit Windows
  • config.h.in etc for size of void * etc.
  • Detecting Python linker flags
  • Building PyGTK etc for our version of Python
  • Packaging it all (will NSIS 32-bit be OK to use?)
