Cannot compile with MinGW

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Attempt to compile glog 0.3.0 with Mingw 4.4.1 (gcc.exe (TDM-2 mingw32)
4.4.1)

What is the expected output? What do you see instead?
Make produces following output:

Same trouble under wine-1.1.38/MinGW-4.4.0

I believe this is because ./configure creates a utilities.h file that should 
include windows/port.h instead of just port.h; however, fixing this simply 
leads to issue 15

I don't think that last solution is correct - though I do not have a Windows 
machine to test.  (To third parties, I'm implicated in this because Warren and 
I are working on a project and he's on the Windows side...)

Let's actually look at the files in the directory.

src/
  config.h
  # other stuff.
  glog/
    log_severity.h
    logging.h
    # other 

  windows/
    config.h
    port.h
    glog/
      log_severity.h
      logging.h
      # other stuff.

You can see that the windows/ subdirectory contains "amended" copies of files 
in the main directory.

So it seems to me that including windows/port.h is not the right thing - in 
fact, the writers of the code are intending to shadow window's "port.h" with 
their own.

It seems to me that the solution is that that src/windows subdirectory needs to 
be in the include path of your compilation before the src/ subdirectory.

 I have to say that I'm not sure how the include path really gets set inside config, but I'm pretty sure that this is the correct diagnosis of the issue.

I did a hack on Makefile to inlcude 'src/windows' with -I option. With this the 
src/windows/port.h is included automatically.

But the below problem remains:

src/windows/port.h: In function 'tm* localtime_r(const time_t*, tm*)':
src/windows/port.h:133:28: error: 'localtime_s' was not declared in this scope
src/windows/port.h: In function 'char* strerror_r(int, char*, size_t)':
src/windows/port.h:138:33: error: 'strerror_s' was not declared in this scope

So i opened the time.h and string.h from C:\MinGW\include to see whether the 
files have the functions localtime_s and strerror_s but there are no such 
definitions.

I have attached the files for reference!

Please advise on how to modify glog source for MINGW!

Hi,

Please dont use MSYS/MINGW for compiling GLOG builds. I fixed the errors with 
src/windows/port.h . But the errors related to src/logging.cc cant be solved as 
MSYS/MINGW does not have 'syslink' (symbolic link) in unistd.h 
(http://mingw.org/wiki/MSYS_1_0_12_Features)

So for WINDOWS environment better use Visual Studio or Cygwin environment!

Thanks
KDK
