C Standard
Code in
PostgreSQL should only rely on language
- features available in the C89 standard. That means a conforming
- C89 compiler has to be able to compile postgres, at least aside
- from a few platform dependent pieces. Features from later
- revision of the C standard or compiler specific features can be
- used, if a fallback is provided.
-
- For example static inline and
- _StaticAssert() are currently used, even
- though they are from newer revisions of the C standard. If not
- available we respectively fall back to defining the functions
- without inline, and to using a C89 compatible replacement that
- performs the same checks, but emits rather cryptic messages.

==========
This directory contains the tools required to build PostgreSQL using
-Microsoft Visual Studio 2005 - 2017. This builds the whole backend, not just
+Microsoft Visual Studio 2013 - 2017. This builds the whole backend, not just
the libpq frontend library. For more information, see the documentation
chapter "Installation on Windows" and the description below.
Mkvcbuild.pm module containing the code to generate the Visual
Studio build (project/solution) files
MSBuildProject.pm module containing the code to generate MSBuild based
- project files (Visual Studio 2010 or greater)
+ project files (Visual Studio 2013 or greater)
Project.pm module containing the common code to generate the
Visual Studio project files. Also provides the
common interface of all project file generators
Solution.pm module containing the code to generate the Visual
Studio solution files.
-VCBuildProject.pm module containing the code to generate VCBuild based
- project files (Visual Studio 2005/2008)
VSObjectFactory.pm factory module providing the code to create the
appropriate project/solution files for the current
environment
These configuration arguments are passed over to Mkvcbuild::mkvcbuild
(Mkvcbuild.pm) which creates the Visual Studio project and solution files.
It does this by using VSObjectFactory::CreateSolution to create an object
-implementing the Solution interface (this could be either a VS2005Solution,
-a VS2008Solution, a VS2010Solution or a VS2012Solution or a VS2013Solution,
+implementing the Solution interface (this could be either a VS2013Solution,
or a VS2015Solution or a VS2017Solution, all in Solution.pm, depending on
the user's build environment) and adding objects implementing the corresponding
-Project interface (VC2005Project or VC2008Project from VCBuildProject.pm or
-VC2010Project or VC2012Project or VC2013Project or VC2015Project or VC2017Project
-from MSBuildProject.pm) to it.
+Project interface (VC2013Project or VC2015Project or VC2017Project from
+MSBuildProject.pm) to it.
When Solution::Save is called, the implementations of Solution and Project
save their content in the appropriate format.
-The final step of starting the appropriate build program (msbuild or vcbuild)
-is performed in build.pl again.
