CoinOptServices

[Frank Kampas]

Is anybody working on fixing CoinOptServices?

[Miles Lubin]

I'm not aware of any broken functionality in CoinOptServices, but it hasn't been updated to get rid of deprecation warnings on 0.5. We'd welcome a PR.

When I run Pkg.build("CoinOptServices") using Julia 5.0 and Windows 10, I get load errors and a build error message.

Please open an issue on the CoinOptServices repository with as much information as you can to help reproduce the problem.

[Frank Kampas]

I've attached the error messages

do you have the lapack dll opened by some other julia process?

the problem occurs when nothing else is open.  

I see on the GitHub page for CoinOptServices that the build is failing for Windows and Linux.

Look at the actual logs. It installs fine, just has a handful of known test failures that are due to bugs in the upstream library. Something is preventing the lapack dll from being overwritten on your system. That's not a problem that's been seen anywhere else as far as I'm aware.

Something is preventing the lapack dll from being overwritten on your system.

Try Process Explorer (https://technet.microsoft.com/en-us/sysinternals/processexplorer.aspx)

  "Find" menu -> "Find a Handle or DLL"

  search for "liblapack" and look at what process owns the handle.

[Frank Kampas]

Process Explorer does not indicate that lapack is being run when the problem occurs. 

I do have mingw installed elsewhere on my computer.

Does

  Find -> Find a Handle or DLL -> "liblapack"

Return any results? The goal is to look for any open handle to "liblapack.dll", which would lead to the "Can not delete" error indicated in the posted error log. (I would not expect "liblapack" to ever be listed in the main Process list)

If the search does not return any results, then the "Can not delete" error may have a different cause.

[Frank Kampas]

Handle or Dll substring "liblapack" returned 0 matching items

[Isaiah Norton]

Other suggestion: try temporarily (re)moving that file (`%/liblapack.dll`).

I wonder if Julia itself is opening the dll for some reason, before WinRPM tries to replace it. (check again with Process Explorer while Julia is still running?)

I removed CoinOptServices and WinRPM and was then able to add CoinOptServices
