I don't know about SDL :) numpy needs manifests at the configuration stage, because it build code snippet which it needs to run, and this requires manifest AFAIK, if you link against msvcr90.dll. I did not want to link with another dll at the configuration stage, because this could lead to subtle issues. > Instead I > link the DLLs against msvcr71.dll, making sure there are also static > libraries, then create the msvcr90.dll linked DLL's from the static > libraries.

My solution to this was to generate the manifest file, which was relatively easy to do since we control our build process in python (look at numpy/distutils/mingw32compiler.py). To run a program 'locally' (one which is not installed), having the manifest in the same directory as the .exe is enough, so we only need to generate it. The main difficulty is to make sure you are using the same version of the dll as python: this feature has been integrated in python 2.6.1. For 2.6.0, I just assume it is the same as the official python binary. > Yes, I've had my run in with manifest files. I avoid them by linking > test programs against msvcrt or msvcr71 instead.

This may be of some interest for you: http://cournape.wordpress.com/2008/09/02/how-to-embed-a-manifest-into-a-dll-with-mingw-tools-only/ that's a summary of my own findings about manifest using only open source tools. All the necessary code, including the manifest template is in the mingw32compiler.py file: http://projects.scipy.org/scipy/numpy/browser/trunk/numpy/distutils/mingw32ccompiler.py cheers, David _______________________________________________ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion
