Hello Denis, I'm wondering if you ever came up with a better solution to the problem of struct packing size differences on Mono/Linux vs. Windows? From what digging around I have done[1], this seems to be a bug in Mono in that it doesn't correctly default to that platform's packing size but always uses 8.

I would really like to not resort to a compiler directive, but since the only way to explicitly set this is with an attribute, the only other option I see is to define two classes whenever such a struct is needed and use a factory method to generate the correct one at runtime.

My goal here is to allow the same compiled assemblies to run correctly on both Linux and Windows but there doesn't seem to be a very clean way to do this.

Thanks,
toby

Hi Toby,

Well, since you have to build and provide the subversion client DLL under Windows, what I thought would be nice to do, is to have a built of this DLL that use the same packing used by Linux. This way, you can avoid the issues found under mono, by fixing structure packing to a common value for both Windows and Linux. However, I have never investigate how to force the Windows compiler to use a particular structure packing, if it is possible.

Regards,

I hadn't really thought about going that route although I'm pretty sure I did see in the MS Compiler options, the ability to set the packing size. I will investigate this option, thanks...
