Packaging existing binaries for multiple platforms

[kevswims]

I have a set of binaries that are compiled for multiple platforms. ex: folder for Win32, Win64, Linux32 etc. I have been able to create a conan package for the Win64 binaries that works correctly. However, when using the Win32 binaries I cannot figure out how to specify the configuration setting to generate a different has for the Win32 configuration. How is this supposed to be defined in the package recipe or otherwise?

I have tried modifying the arch setting in the conaninfo.txt but this still produced the same hash as the Win64 package.

@memsharded Can you help with this one?

This is mostly resolved by this question I asked on StackOverflow: https://stackoverflow.com/questions/45202046/using-conan-to-package-multiple-configurations-of-preexisting-binaries

I think the documentation of this example should be updated to include the info given in the response. This is the line that should be mentioned:
$ conan package_files libname/1.1.1@name/testing -s arch=x86 # 32 bits instead of 64

The answer's explanation of profiles is not clear to me either but that is beyond the scope of this issue.

That's great! Can you please create a PR with the changes?

[kevswims]

Yes, I'll try and get a pull request submitted by the end of the weekend.

Ok, great, if @kevswims can help with this, really appreciated (sorry for the delay).

I also think that the example of consumer is a bit off-topic and also not the standard. Packages created with this technique are just regular packages, and can be consumed exactly the same as any other conan package, so not necessary.

I will also try to contribute when @kevswims does the PR. Thanks to both!

@memsharded Can you look at the changes? I am also planning to test packaging out with a custom non-default architecture so can improve the documentation once I play around with it.

Let me know if you need any more help with this use case. I ended up writing an automated script that runs through a set of directories containing binaries for multiple platforms, packages them, uses a set of profiles for each platform for the settings, and uploads them to an artifactory instance.

Ah awesome! Is the recipe something you can share? Maybe you can create another repo showcasing that? It would be really useful because I am just about to embark on that same journey!
