This project has begun being ported to Windows.  A working solution
file exists in this directory:
    google-perftools.sln

You can load this solution file into either VC++ 7.1 (Visual Studio
2003) or VC++ 8.0 (Visual Studio 2005) -- in the latter case, it will
automatically convert the files to the latest format for you.

When you build the solution, it will create a number of unittests,
which you can run by hand (or, more easily, under the Visual Studio
debugger) to make sure everything is working properly on your system.
The binaries will end up in a directory called "debug" or "release" in
the top-level directory (next to the .sln file).  It will also create
two binaries, nm-pdb and addr2line-pdb, which you should install in
the same directory you install the 'pprof' perl script.

Note that these systems are set to build in Debug mode by default.
You may want to change them to Release mode.

To use tcmalloc_minimal in your own projects, you should only need to
build the dll and install it someplace, so you can link it into
further binaries.  To use the dll, you need to add the following to
the linker line of your executable:
   "libtcmalloc_minimal.lib" /INCLUDE:"__tcmalloc" 

Here is how to accomplish this in Visual Studio 2005 (VC8):

1) Have your executable depend on the tcmalloc library by selecting
   "Project Dependencies..." from the "Project" menu.  Your executable
   should depend on "libtcmalloc_minimal".

2) Have your executable depend on a tcmalloc symbol -- this is
   necessary so the linker doesn't "optimize out" the libtcmalloc
   dependency -- by right-clicking on your executable's project (in
   the solution explorer), selecting Properties from the pull-down
   menu, then selecting "Configuration Properties" -> "Linker" ->
   "Input".  Then, in the "Force Symbol References" field, enter the
   text "__tcmalloc" (without the quotes).  Be sure to do this for both
   debug and release modes!

You can also link tcmalloc code in statically -- see the example
project tcmalloc_minimal_unittest-static, which does this.  For this
to work, you'll need to add "/D PERFTOOLS_DLL_DECL=" to the compile
line of every perftools .cc file.  You do not need to depend on the
tcmalloc symbol in this case (that is, you don't need to do either
step 1 or step 2 from above).

The heap-profiler has had a preliminary port to Windows.  It has not
been well tested, and probably does not work at all when Frame Pointer
Optimization (FPO) is enabled -- that is, in release mode.  The other
features of perftools, such as the cpu-profiler and leak-checker, have
not yet been ported to Windows at all.

I have little experience with Windows programming, so there may be
better ways to set this up than I've done!  If you run across any
problems, please post to the google-perftools Google Group, or report
them on the google-perftools Google Code site:
