Cobra Forums

Hello

I have installed Cobra 0.94 on Windows 7 amd64 successfully some time ago.

U:\projs\>cobra -about

The Cobra Programming Language 0.9.4
on .NET CLR v4.0.30319 on Microsoft Windows NT 6.1.7601 Service Pack 1
at C:\Cobra\Cobra-0.9.4\bin\cobra.exe

Usage: cobra -h

But while trying to build a Ubuntu installation I noticed that Cobra was now at 0.96. So after installing it on Ubuntu I downloaded the zip archive to update the Windows installation. I renamed the old installation directory from C:\Cobra to C:\__Cobra, just in case I need it later.

I then ran the installation script but received an error which I no longer have access to as I closed the CMD window after it recommended running the script as Administrator. I did that and I still got an Error as follows (this is the end of output):

==== Locate msbuild.exe

Found: C:\Windows\Microsoft.NET\Framework\v4.0.30319\msbuild.exe

Need help with the above error?
* Make sure you ran as a Windows Administrator.
* Install .NET or a Visual Studio product if you have not before.
* Review http://cobra-language.com/troubleshooting

I tried to use the "ldr64 setwow" tip found in the troubleshooting guide (as I remember faintly I had to use it for the 0.94 version-- or at least I investigated it before-- and then run the install script but I still got the same error. I have since ran "ldr64 set64" to switch back.

What am I doing wrong?

Thanks


PS I renamed the old Cobra installation to reactivate it and it is still running fine.

You probably don't have to rename the \Cobra directory, because Cobra actually installs the specific version under that.

Regarding your problems, the thing that really stands out is the mismatch in version numbers:

Code: Select all

Found: C:\Windows\Microsoft.NET\Framework\v4.0.30319\msbuild.exe
...
run: C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin\gacutil.exe -l Cobra.Core
: Microsoft (R) .NET Global Assembly Cache Utility. Version 3.5.30729.1

Looks like it finds msbuild from .NET 4 but then only finds the GAC from .NET 3.5.

I'm curious what your 0.9.4 cobra says for "cobra -about". This will report the .NET runtime which should be either 2.x or 4.x (.NET 3.0 and 3.5 and just libraries that run on the 2.x run-time).

I'm also curious about the output for:

Code: Select all

cd \Windows
dir msbuild.exe /s
cd \Program Files
dir gacutil.exe /s


With the above information, we may be able to improve the installer to work right, or at least detect the situation and give an informative message.

Ideas for getting 0.9.6 on your system:

-- Install the .NET SDK and the install from the SDK prompt.
-- Or, same thing, but install a recent Visual Studio Express.

Hello Charles,

The output of "Cobra --about" for version 0.94 is in my first post above. As for the other output you were interested in seeing, here it is:

I think I may have the .NET and Windows SDKs installed and I do have Visual Studio Express 2010 installed as well, if that makes a difference. Given how many of these exist and the how long ago they were installed, I have to say that I could be mistaken concerning the .NET SDK being on the system. Is there a test or output from some program(s) you suggest I run to make sure that the system meets the installation requirements of Cobra 0.96?

I say that also because I am curious as to why Cobra 0.94 found enough resources (of SDK, etc.) to get itself installed but Cobra 0.96 couldn't.

Regards

So it's interesting that you have a newer gacutil from your directory listing:
C:\Program Files\Microsoft SDKs\Windows\v7.1\Bin

Than what the installer picked up:
run: C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin\gacutil.exe -l Cobra.Core

Looking in CobraWorkspace/Source/InstallFromWorkSpace.cobra, I see these directories:

Obviously 7.1 is missing. Looking at the comments, that would obviously correspond to VS2010 which is congruent with your comments.

So I think you should be able to get the installer working by adding the path in there or installing VS 2012 or installing .NET SDK 4.5. Your choice. Let us know how it goes.

In the future, it might not hurt for us to add command line options for the location of gacutil and msbuild.

Okay. So I have tried the first option: adding the VS2010's binary path to the installation script, as suggested. That unfortunately didn't work. I even deleted the previously compiled Cobra files and the unzipped archive contents to start with a clean slate; still a no go.

So that leaves me with the other two options, which require relatively more time and effort. I'll report back when I have news.

Thanks

I didn't have to install anything new. It seems that the path to VS2010's gacutil.exe needed tweaking. Apparently this

Code: Select all

r'\Program Files\Microsoft SDKs\Windows\v7.1\Bin',    # VS 2010


does not work. But this does:

Code: Select all

r'\Program Files\Microsoft SDKs\Windows\v7.1\Bin\NETFX 4.0 Tools\x64', # VS2010
r'\Program Files\Microsoft SDKs\Windows\v7.1\Bin\NETFX 4.0 Tools', # VS2010


At any rate, I hope someone will benefit from this.

Regards

Thanks for reporting back. I'll add those paths to the installer though currently the .NET requirement has jumped to 4.5 which was released August 2012. (We could always roll back to 4.0 though some effort is required.)
