Mike and Abhinav

I have tried pytave configure.

Preparation
1. octave 4.1.0+ for windows + msys2 + python2.7
2. The python 2.7 for windows is used download from python's official web.

 Note : The python 2.7 for windows has libpython27.a in C:\Python27\lib


Step
1. execute octave-cli for 4.1.0+

2. execute bash
>> cd D:\usr\Tatsu\program\Pytave\PytaveBuild\Pytave\build #goto build directory
>> system bash # execute bash embedded to octave


3. setting and configure

$ export PATH=$PATH:/c/msys64_gcc530/usr/bin:/c/Python27:/c/Python27/scripts 
#PATH setting for msys2 and python

$ export CPPFLAGS='-I/c/Python27/include 
-I/d/usr/Tatsu/program/Pytave\/PytaveBuild/boost/boost_1_16_inst/include'
$ export LDFLAGS='-L/c/Python27/libs 
-L/d/usr/Tatsu/program/Pytave/PytaveBuild/boost/boost_1_16_inst/libs'
$ ../pytave/configure LIBS='-Lc:/Python27/libs' \
> --prefix=/d/usr/Tatsu/program/Pytave/PytaveInst 
> --with-octave=/c/octave/octave-4.1.0plus.2016-06-08-08-23

******************************************

As error message suggested, I set LIBS='-Lc:/Python27/libs'
However, that seems not to be detected.

configure:5612: checking python extra linking flags
configure:5619: result: None

Any suggestions?
