I am attempting to compile Audacity 2.0.0 and am receiving the following error. I am new to C/C++ so am unsure how to troubleshoot it. I am using VS 2010 Professional SP1.

Error 449 error MSB4023: Cannot evaluate the item metadata "%(Extension)". The item metadata "%(Extension)" cannot be applied to the path ""C:\audacity-src-2.0.0\win\Debug\Audacity.vcxproj\analyze.ny"". Illegal characters in path. C:\audacity-src-2.0.0\win\ny.targets 65 6 Audacity

Here is my ny.targets file. I have done some Googling, but so far it has been fruitless.

For the record, your problem is caused by the quotation marks.

Turn:

""C:\audacity-src-2.0.0\win\Debug\Audacity.vcxproj\analyze.ny""

Into

"C:\audacity-src-2.0.0\win\Debug\Audacity.vcxproj\analyze.ny"

How you do that will depend on how you're passing in the input.

While I didn't figure out the root of the error, I did find the workaround.

The workaround is don't use VS2010 to compile Audacity.

Use VS2008 — it worked right off the bat with 2008.

This link, http://wiki.audacityteam.org/wiki/Developing_On_Windows#What_about_Visual_Studio_2010.3F__Or_64-bit.3F, gives detailed instructions.

VC++ 2008 Express installs side by side with 2010, no problems.

Here is the thread where they are trying to get it to work with 2010, http://forum.audacityteam.org/viewtopic.php?f=19&t=61946

The trick to compiling the very current code from Sourceforge in VS2010 is modifying the ny.props file in 1 place, and expanding the variables in the Pre-Build and Post-Build steps of portaudio-v19 and portmixer. I cannot seem to get the environment variables in VS2010 to take as used below, in the current solution. Expanding them seems to get past this. However, predeclared variables like the SDK directory environment variable work fine.

Also, the single fix for the quotes in the ny.props file fixes all cascades later on. This seems to be the minimal fix to get it to compile properly.

The fix is below:

ny.props original:

<?xml version="1.0" encoding="utf-8"?>
<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <PropertyGroup
    Condition="'$(copyBeforeTargets)' == '' and '$(copyAfterTargets)' == '' and '$(ConfigurationType)' != 'Makefile'">
    <copyBeforeTargets>Midl</copyBeforeTargets>
    <copyAfterTargets>CustomBuild</copyAfterTargets>
  </PropertyGroup>
  <PropertyGroup>
    <copyDependsOn
      Condition="'$(ConfigurationType)' != 'Makefile'">_SelectedFiles;$(copyDependsOn)</copyDependsOn>
  </PropertyGroup>
  <ItemDefinitionGroup>
    <copy>
      <OutputName>"$(OutDir)$(ProjectFileName)\%(Filename)%(Extension)"</OutputName>
      <CommandLineTemplate>copy /Y [inputs] %(OutputName)</CommandLineTemplate>
      <Outputs>%(OutputName)</Outputs>
      <ExecutionDescription>Copying %(Filename)</ExecutionDescription>
    </copy>

</Project>

I don't have enough reputation to comment on Tom Bonner's answer, but using that information, I found the solution for my identical problem (with a different code base) was to find the .props file in the same directory as the .targets file, and with the same name (i.e. QtUIBuild.props and QtUIBuild.targets), and look for the offending path. In my case it was a matter of changing

<Outputs>".\..\..\source\qt\GeneratedFiles\ui_%(Filename).h"</Outputs>

to

<Outputs>.\..\..\source\qt\GeneratedFiles\ui_%(Filename).h</Outputs>
