I did a git pull today of IronLanguages\main, and noticed a giant stack of changes on December 30, 31 and Jan 1 - which look like they’re related to Win8 and Mango, amongst other things. I’m trying to build the IronRuby installer - the process also builds the IronPython installer along with it. It ( msbuild /p:Configuration=Release Installer.proj ) now fails with several errors: 1 - IronRubyTools.dll fails to build. It complains about "A reference was created to embedded interop assembly ‘…\VSLangProj.dll’ - I fixed this by setting Embed Interop Types = false on that reference (what happened to break this??) 2 - The build now fails because it couldn’t find silverlight 4 dll’s, whereas it used to work (did it used to reference silverlight 3 which ships with VS2010??). - I fixed the error by installing the silverlight 4 SDK 3 - Two proj files have gone missing: c:\Dev\ironlanguages-main\Msi\Installer.proj(23,9): error MSB3202: The project file “Python\Chm\IronPython.Chm.proj” was not found. c:\Dev\ironlanguages-main\Msi\Installer.proj(23,9): error MSB3202: The project file “Python\Msi\IronPython.Msi.wproj” was not found. It seems these have vanished?? I tried to work around this by manually building only Ruby\Msi\IronRuby.Msi.wproj 4 - This now fails with c:\Dev\ironlanguages-main\Msi\Ruby\Msi\Silverlight.wxi(14): error CNDL0150: Undefined preprocessor variable ‘$(var.OutputPath)’. [c:\Dev\ironlanguages-main\Msi\Ruby\Msi\IronRuby.Msi.wproj] It looks like that Wxi file hasn’t changed recently, so presumably something else is ruining the outpath? - I fixed this by editing IronRuby.wxs and removing all mention of silverlight… This is fine for me, as I don’t want to go near silverlight, but others may require a better solution 🙂 5 - Now there’s a bunch of errors all like this: c:\Dev\ironlanguages-main\Msi\Ruby\Msi\IronRuby.wxs(92): error LGHT1055: The InstallExecuteSequence table contains an action ‘NetFxScheduleNativeImage’ which cannot be merged from the merge module ‘c:\Dev\ironlanguages-main\bin\Release \IrbRedist.msm’. This action is likely colliding with an action in the database that is being created. The colliding action may have been authored in the database or merged in from another merge module. If this is a standard action, it is likely colliding due to a difference in the condition for the action in the database and merge module. If this is a custom action, it should only be declared in the database or one merge module. [c:\Dev\ironlanguages-main\Msi\Ruby\Ms i\IronRuby.Msi.wproj] This is where I give up… The giant stack of changes mostly came from Tomas M. / JDHardy / couple of other IronPython devs… Would one of those people mind please having a look at this?

Yes, the installer is broken. Jeff is working on some better installer building scripts. I’m not sure what the status is atm.

The IronPython ones should be working, and nothing I did should change IronRuby’s installer builds. However, the old build script may reference IronPython installers that no longer exist. - Jeff On Tue, Jan 3, 2012 at 8:14 PM, Tomas M.
