Build Fails on MinGW32

[GoogleCodeExporter]

When trying to build the google-perftools on MinGW32 the build fails.

The problem is that when building with make, it is assumed that is is a 
Posix target, but it is a Win32 target. As a result it is required to have 
Visual Studio to build on Windows.

To reproduce the error: (On a Windows platform.)

1.  Install MinGW & MSYS.

2.  tar -xzvf google-perftools-0.93.tar.gz

3.  ./configure 

4.  make

This requires only a change in the buildsystem, since the code for Windows 
is already there.

MinGW is a tricky environment; it's some mix of win32 and posix.

It would be very helpful to see the rest of the error report.  What happens 
when you
type 'make'?  Seeing the configure output would be very helpful too.

To make a lang log short. It fails while trying to build against pthreads. I 
will
provide more details later. In my opinion is that it does not use the sources in
src/windows.

In my experience MinGW with MSYS is just win32 with gcc and gnu build 
environment.
The main thing to do is to make a conditional build, eg. with AM_CONDITIONAL. 
Cygwin
on the other hand is a different issue.

I will look into to issue and provide more info and implementation help in the 
coming
days.

I instaleld MinGW and MSYS to play around with, and ran into the same problems 
with
pthreads that you mention.  Looking on the web, I see that msys does not support
pthreads, so no surprise there's a problem.

The solution, as you point out, is to use the windows code we have to implement 
the
threading library, instead of using pthreads.  But I couldn't figure out how to 
get
that to work either.  I believe that MSYS is win32 with a unix build 
environment, but
I dont' know how to get access to the win32 part.  I don't see windows.h 
anywhere
inside the msys shell, for instance.

If you have any hints on how to get windows/port.h and port.cc to compile under 
msys,
I'll be happy to make the requisite configure changes to get that to work 
automagically.

Never mind, I found windows.h.  I'll see what I can do to get something to 
compile
under msys for the next release.

I've got the build working for mingw now (it was a lot of work!)  I expect 
something
will be out in the next release -- hopefully this week.  There are still some
problems with the linker (I think), so I'm not sure everything will work 
perfectly,
but it's a good start.

Should be fixed in perftools 0.94
