Building LibSass with Visual Studio

Requirements:

The minimum requirement to build LibSass with Visual Studio is "Visual Studio 2013 Express for Desktop".

Additionally, it is recommended to have git installed and available in PATH, so to deduce the libsass version information. For instance, if GitHub for Windows (https://windows.github.com/) is installed, the PATH will have an entry resembling: X:\Users\<YOUR_NAME>\AppData\Local\GitHub\PortableGit_<SOME_GUID>\cmd\ (where X is the drive letter of system drive). If git is not available, inquiring the LibSass version will result in [NA].

Build Steps:

From Visual Studio:

On opening the win\libsass.sln solution and build (Ctrl+Shift+B) to build libsass.dll.

To Build LibSass as a static Library, it is recommended to set an environment variable LIBSASS_STATIC_LIB before launching the project:

cd path\to\libsass
SET LIBSASS_STATIC_LIB=1
::
:: or in PowerShell:
:: $env:LIBSASS_STATIC_LIB=1
::
win\libsass.sln

Visual Studio will form the filtered source tree as shown below:

Header Files contains the .h and .hpp files, while Source Files covers .c and .cpp. The other used headers/sources will appear under External Dependencies.

If there is a LibSass code file appearing under External Dependencies, it can be changed by altering the win\libsass.vcxproj.filters file or dragging in Solution Explorer.

From Command Prompt:

Notice that in the following commands:

• If the platform is 32-bit Windows, replace ProgramFiles(x86) with ProgramFiles.
• To build with Visual Studio 2015, replace 12.0 with 14.0 in the aforementioned command.

Open a command prompt:

To build dynamic/shared library (libsass.dll):

:: debug build:
"%ProgramFiles(x86)%\MSBuild\12.0\Bin\MSBuild" win\libsass.sln

:: release build:
"%ProgramFiles(x86)%\MSBuild\12.0\Bin\MSBuild" win\libsass.sln ^
/p:Configuration=Release

To build static library (libsass.lib):

:: debug build:
"%ProgramFiles(x86)%\MSBuild\12.0\Bin\MSBuild" win\libsass.sln ^
/p:LIBSASS_STATIC_LIB=1

:: release build:
"%ProgramFiles(x86)%\MSBuild\12.0\Bin\MSBuild" win\libsass.sln ^
/p:LIBSASS_STATIC_LIB=1 /p:Configuration=Release

From PowerShell:

To build dynamic/shared library (libsass.dll):

# debug build:
&"${env:ProgramFiles(x86)}\MSBuild\12.0\Bin\MSBuild" win\libsass.sln

# release build:
&"${env:ProgramFiles(x86)}\MSBuild\12.0\Bin\MSBuild" win\libsass.sln `
/p:Configuration=Release

To build static library (libsass.lib):

# build:
&"${env:ProgramFiles(x86)}\MSBuild\12.0\Bin\MSBuild" win\libsass.sln `
/p:LIBSASS_STATIC_LIB=1

# release build:
&"${env:ProgramFiles(x86)}\MSBuild\12.0\Bin\MSBuild" win\libsass.sln `
/p:LIBSASS_STATIC_LIB=1 /p:Configuration=Release
