AppVeyor builds fail due to missing LZ4 #355

Closed brawer closed 2 years ago

brawer commented 2 years ago

The AppVeyor configuration for libosmium appears to be broken. For example, see this AppVeyor build for a pull request that fails with the following error message. The pull request is unrelated to the error; probably the AppVeyor config needs to be updated.

Nuget has an LZ4 package: https://www.nuget.org/packages/lz4/

brawer commented 2 years ago

@smasherprog, since you’re maintaining a bunch of nuget packages including lz4, would you perhaps be interested to build and maintain a nuget package lz4.v140 with pre-compiled native object files?

Context: Osmium is a multiplatform C++ library for processing OpenStreetMap data. To make sure it doesn’t break on Windows, there’s a continuous build on AppVeyor, but it’s been broken for a while due to a newly added dependency on LZ4. I tried fixing this by using @smasherprog’s lz4 nuget package. However, the linker fails because it cannot open file C:\projects\lz4.1.3.1.2\build\native\lib\x64\Debug\liblz4d.lib; see error log. Indeed, looking at the package contents, there’s no content in build\native\lib\x64\Debug. Could that be added? I know very little about nuget, Visual Studio, or the Windows platform in general (my last serious project had been on Windows NT 3.51, ahem), so I don’t feel confident to do this myself.

The appveyor build isn't actually that important. It is rather an old setup and I just left it in, because I had it anyway. It would be more important to fix the Github Windows builds.

Oh, that’s good to know! In that case, should the AppVeyor project be shut down, and its config file deleted? Assuming there’s not much value in keeping a broken build around.

Just saw this comment. I dont maintain that library any more. I am more than happy to make you a contributor on it if you want!
