I have enhanced the -lib option to take environment variables as well as the special variable {@latest}. Here is a real example used for Windows Presentation Foundation (WPF) which was the main inspiration for this:

Code: Select all: # at the command line: cobra -lib:'{ProgramFiles|ProgramFiles(x86)}\Reference Assemblies\Microsoft\Framework\.NETFramework\{@latest}' foo.cobra ...

# or you can put it in your source code with @args:
@args lib:'{ProgramFiles|ProgramFiles(x86)}\Reference Assemblies\Microsoft\Framework\.NETFramework\{@latest}'

@ref 'WindowsBase'
@ref 'PresentationCore'
@ref 'PresentationFramework'
@ref 'System.Xaml'

use System.Windows
use System.Windows.Media
# ...

As you can see from the example you can actually have more than one env var separated by vertical bars: {foo|bar|baz}

The first path that actually exists on disk at the time of compilation "wins". Then {@latest} can be used to distinguish between directories like "v4.0", "v4.5" and "v4.5.1". The "v" prefix is optional.

Those of you who run the compiler test suite shouldn't see any more WPF errors. If you do, let me know.

For everyone: If you have problems with this, let me know here. If you come up with other uses for it besides WPF, please share in this thread.

Still gives WPF compile errors on my system ( Windows 7 64 bit Net4)

The new expansion code works fine but on this system there is no '.NetFramework' dir in
'{ProgramFiles|ProgramFiles(x86)}\Reference Assemblies\Microsoft\Framework\''

theres only version dirs for net version 3 (v3.0 and v3.5).

The requisite files are in '{WinDir}\Microsoft.NET/{Framework|Framework64}/' but then you have to somehow wire/detect/use the
correct platform bitsize (64 or 32 bit platform) so a simple either-or existence option test is still insufficient.

I went through this when doing the patch for ticket:332
and vaguely recollect that one of the SDK/IDE installs sets up the 'Reference Assemblies' dir for some platforms - but not mine - or I just havent installed the 'right' IDE/SDK software pkg or something ... Its subject to installation/config instability anyway.

Think you're better off providing a magic static tag value for most of the framework path that the compiler expands for the platform...
It does its own probing/detection/lookup to work out what that is exactly.....

Thanks for the report and details. How sad that the .NET cannot decide where to put their damn files.

What exactly do you see in your '{WinDir}\Microsoft.NET/{Framework|Framework64}/' directory? In other words, does that have "v4.0" and "v4.5"?

What shall we call the special {@var}? Maybe {@framework}

Just 4, nothing later ( no 4.5)

Code: Select all: 591 xx:...wkspace1/Source> ls /Windows/Microsoft.NET/Framework64 SharedReg12.dll sbscmp20_mscorwks.dll v2.0.50727 v3.5 sbscmp10.dll sbscmp20_perfcounter.dll v3.0 v4.0.30319 592 xx:...wkspace1/Source> ls /Windows/Microsoft.NET/Framework NETFXSBS10.exe sbs_system.data.dll SharedReg12.dll sbs_system.enterpriseservices.dll netfxsbs12.hkf sbs_wminet_utils.dll sbs_VsaVb7rt.dll sbscmp10.dll sbs_diasymreader.dll sbscmp20_mscorwks.dll sbs_iehost.dll sbscmp20_perfcounter.dll sbs_microsoft.jscript.dll v1.0.3705 sbs_microsoft.vsa.vb.codedomprocessor.dll v1.1.4322 sbs_mscordbi.dll v2.0.50727 sbs_mscorrc.dll v3.0 sbs_mscorsec.dll v3.5 sbs_system.configuration.install.dll v4.0.30319 593 xx:...wkspace1/Source>

Have a look at the ticket/patch
I made two variables one for the full (latest) frame work path ( called {_FWP} -> '{@FullFrameworkPath}')
and one for just the
single directory for current Framework-with-wordsize expansion ( '{_FW}' -> '{@FrameworkSize}' (??)

this allows simple compiler determine spec of 'system' path

Code: Select all: @args -lib:'{_FWP}\WPF' @ref 'PresentationFramework' @ref 'PresentationCore' @ref 'WindowsBase' # can also fully detail overiding #@ref '{_FWP}\WPF\PresentationCore' #@ref 'C:\Windows\Microsoft.NET\{_FW}\v4.0.30319\WPF\WindowsBase' @ref 'System.Xaml'

or full detail specified breakdown

Code: Select all: @ref 'C:\Windows\Microsoft.NET\{_FW}\v4.0.30319\WPF\PresentationFramework' # better #@ref 'C:\Windows\Microsoft.NET\{_FW}\{@latest}\WPF\PresentationFramework' or @args -lib: '{WinDir}\Microsoft.NET\{_FW}\{@latest}\WPF' @ref 'PresentationFramework' @ref 'PresentationCore' @ref 'WindowsBase' @ref 'System.Xaml' or (current only allow @latest last) @args -lib: '{WinDir}\Microsoft.NET\{_FW}\{@latest}' @ref 'WPF\PresentationFramework' @ref 'WPF\PresentationCore' @ref 'WPF\WindowsBase' @ref 'System.Xaml'

I haven't tried these yet and I'm about to turn in, but I noticed you have "...\WPF" in your lib paths, but there is no WPF subdirectory in the .NET 4.5.1 SDK on Win 8.1. It's simply:

C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5.1

PresentationCore.dll is directly in there right next to various other DLLs like System.Data.dll. So a directive, whether -lib or @ref, that uses "\WPF" will still fail in some environments (and vice versa).

@hops, can you give me the output for this on your system:

re WPF
I'm on Windows 7 (Microsoft Windows 6.1.7601).
I dont have Net4.5 installed SFAICT - no Net 4.5 dirs

Both /Windows/Microsoft.NET/Framework/v4.0.30319 and /Windows/Microsoft.NET/Framework64/v4.0.30319
have WPF directories
( those examples were out of the ticket patch I made - all passed )

Part of your output came through as:

Code: Select all: Directory of C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\ .0

In any case, what I have read is that \Windows\Microsoft.NET... is the GAC which is read only at run-time and \Program Files...\Reference Assemblies\... contains reference assemblies that are only read at compile-time. Although I haven't read a clear explanation of what the motivation or benefit is for separating the two.

Getting back to your machine, it's apparent that you have installed the .NET 4 client, but not the SDK or Visual Studio. So the question is whether or not we want to require the SDK when developing for Cobra?

I thought I also read somewhere that the .NET run-time no longer ships with csc.exe which we rely on. That would add more weight to requiring the SDK if that's true.

Also, I'm curious where your msbuild for .NET 4 is located or if you even have one.

MSBuild.exe should be in C:\Windows\Microsoft.NET\Framework|Framework64\v4.0.30319 for .NET 4. It will no longer be shipped with .NET in the future and instead is bundled with Visual Studio or as part of a separate SDK install.
