i686-pc-windows-gnu package missing required DLLs

[Diggsey]

This package used to include libgcc_s_dw2-1.dll and libstdc++-6.dll in the rustc/bin folder. In the latest releases these DLLs are missing, which results in rustc failing to start.

This is possibly a result of #29009

[alexcrichton]

I believe this should be fixed by #29195

[alexcrichton]

Fixed in #29195

Still experiencing this on 1.5.0-nightly (1210fb9 2015-10-23)

[alexcrichton]

@tikue are you sure? Can you show the steps you're reproducing with? Downloading the nightly shows that the DLLs are in the right locations for me.

@alexcrichton I can reproduce with today's 1.5 nightly installer. libstdc++-6.dll is missing:

@iliekturtles are you sure you also downloaded the most recent nightly? I just downloaded the 32-bit gnu msi and the files were installed.

[Diggsey]

This seems to have fixed it for me: the latest nightly works both on appveyor and locally.

[tikue]

@Diggsey try uninstalling any other versions of rust before testing

[rouge8]

I'm having what I think is the same issue with the 64bit installers on Appveyor:

Start-FileDownload "https://static.rust-lang.org/dist/rust-nightly-${env:TARGET}.exe"
rust-nightly-%TARGET%.exe /VERYSILENT /NORESTART /DIR="C:\Rust"
SET PATH=%PATH%;C:\Rust\bin
SET PATH=%PATH%;C:\MinGW\bin
rustc -V
*hangs indefinitely*

[iliekturtles]

I just noticed that this patch fixed the i686 installer. There is also an issue with the x86_64 installer.

@rouge8 Definitely, the missing DLL pops up a dialog box.
