Cobra Forums

Below is a list of recent improvements to the installer. These are the all the ones I have planned for the upcoming release. I have tested on Windows, Mac, Linux, .NET and Mono, with various versions. Please test on your current platform and chime in on this thread with your results ("success" or "problem ...") and your platform info (the first part of the installer output). See HowToInstallFromSource if you are not already setup with a Cobra source code workspace.

Recent improvements:

-- At the end of installation, you can and should change out of the workspace directory. On Windows, this is now done automatically. On Unix-family, where shells cannot have their directory changed by a child process, you are instructed to do so. (Thanks for the feedback, DelphiGuy.)

-- The gacutil.exe for .NET 4.0 on Windows is looked for in more places than before.

-- On Windows, if you install for .NET 4.0 and no gacutil.exe 4.0 can be found, then you are correctly instructed to install the Windows SDK and given the URL (only half a meg download).

-- The installer prints correct operating system and platform information. This was previously buggy on Windows and in need of better formatting in general.

-- On Unix-family, if "cobra" is not in the path and the path includes the directory "/usr/local/bin" then "cobra" is added there.

-- Cobra.Lang.Compiler.dll is now correctly installed and usable.

-- On a related note, "cobra -about" now prints good info about subversion revision, install date, Mono version, CLR version, op sys description and cobra's installed path.

Enjoy.

Success

After the predicted lack of gacutil.exe causes a failure installing for NET 4.0:
After using the SDK installer to install just the NET tools, fails with:

==== Install Cobra.Lang library to the GAC

run: C:\Program Files\Microsoft SDKs\Windows\v7.1\Bin\gacutil.exe -i Cobra.Lang.
dll -f
: Microsoft (R) .NET Global Assembly Cache Utility. Version 3.5.30729.1
: Copyright (c) Microsoft Corporation. All rights reserved.
:
: Failure adding assembly to the cache: This assembly is built by a runtime
newer than the currently loaded runtime and cannot be loaded.

** ERROR: Exit code from above command: 1

And the same error after installing the reference assemblies i.e. selecting the entire NET development part of the SDK installer.

I don't need NET 4.0, so I'm happy to install for a non-NET 4.0 version.

Regards, Obtuse.

I'd still like to fix this and I think I know how. Can you tell me the contents of:

dir "C:\Program Files\Microsoft SDKs\Windows\v7.1\Bin"

?

I did this earlier today with success. My info is below. The only thing I wasn't sure about was how to answer the question regarding installing for .NET 4.0 since I was on Ubuntu. I answered no so I'm not sure what version it was installed for. 2.0?

Mono 2.6 --> .NET 2.0

Mono 2.10 --> .NET 4.0 (and .NET 2.0)

Since you are on Mono 2.10 it should have defaulted to .NET 4.0 by having "...[y]" at the end of the question.

For the most part, it does not matter, unless you find yourself trying to call to the .NET 4.0 APIs.

I'm doing most of my Cobra work on Ubuntu 12.04 btw. I still test on the other platforms (Mac, Windows).

@ObtuseAngle, there is a program in Cobra\Supplements called find-gacutil.cobra. Can you run this and share the file output at the end where it summarizes what it found? That would be very helpful.

Thanks for the info about Mono and .NET versions. Good to know. I reinstalled and answered yes this time and everything still worked.

In regards to Ubuntu, any plans for a deb package or ppa?
