unable to comile PostgreSQL with error message "could not find shared library for Python"

I've been trying to build the REL_10_STABLE version of PostgreSQL using MSYS2 in windows 10 environment.Here is the command that I execute for configuring the build:
./configure --enable-thread-safety --enable-nls --with-ldap
--with-openssl --with-ossp-uuid --with-libxml --with-libxslt --with-icu --with-tcl --with-perl --with-python
but I get this error message:
checking for python... no
checking for python3... no
checking for python2... /mingw64/bin/python2
checking for Python distutils module... yes
checking Python configuration directory... C:/msys64/mingw64/lib/python2.7/config
checking Python include directories... -IC:/msys64/mingw64/include/python2.7
checking how to link an embedded Python application... configure: error: could not find shared library for Python
You might have to rebuild your Python installation. Refer to
the documentation for details. Use --without-python to disable building
PL/Python.
As you can see python 2.7 is installed which is the version I need to use and I need the python to be built with python, but I keep getting the error message "could not find shared library for Python".Any help is very much appreciated.
Thank youSam

Most likely you have built your python executable without the --enable-shared flag.
The PostgreSQL documentation says the following:
Since PL/Python will be a shared library, the libpython library must be a shared library also on most platforms. This is not the case in a default Python installation built from source, but a shared library is available in many operating system distributions. configure will fail if building PL/Python is selected but it cannot find a shared libpython. That might mean that you either have to install additional packages or rebuild (part of) your Python installation to provide this shared library. When building from source, run Python's configure with the --enable-shared flag.

Config variable 'Py_DEBUG' is unset

I tried installing matplotlib whl file in python 3.6 on windows but I all I got was this error:
C:\Python36\lib\site-packages\wheel\pep425tags.py:77: RuntimeWarning: Config variable 'Py_DEBUG' is unset, Python ABI tag may be incorrect warn=(impl == 'cp')):
I tried debugging it but it seems to be a real issue here:
https://github.com/pypa/pip/issues/3383
Could someone please let me know how do I solve this error?
Any help would be appreciated.
Thanks.

Although this answer is irrelevant (and outdated) to the original question, people come here after Googling for this very error.
At the end of the day, it usually turn out to be some kind of package compilation error when using pip install . and build related installs. Most likely because the build config was made primarily for a unix OS and not windows. Who knows. So try to use a different compiler or make sure you have installed all the required compiler components. I.e. for Windows that is a >7 GB of Visual Studio C/C++ development/tools install. You may also try the 1 GB MinGW install.
However, the following official documentation clearly state the use for Py_DEBUG.
Compiling the interpreter with the Py_DEBUG macro defined produces what is generally meant by a debug build of Python. Py_DEBUG is enabled in the Unix build by adding --with-pydebug to the ./configure command. It is also implied by the presence of the not-Python-specific _DEBUG macro. When Py_DEBUG is enabled in the Unix build, compiler optimization is disabled.

Configure error while installing graph-tool on ubuntu 14.04

So I spent a whole day trying to find out the solution for this. I am trying to install graph-tool on my machine with 14.04 OS. Initially I was unable to succeed because I didn't have gcc 5 on my machine. After installing it, I am trying the following:
./configure CXX='g++5'
and I get the following error:
===========================
Using python version: 2.7.6
===========================
checking for boostlib >= 1.54.0... configure: We could not detect the boost libraries (version 1.54 or higher). If you have a staged boost library (still not installed) please specify $BOOST_ROOT in your environment and do not give a PATH to --with-boost option. If you are sure you have boost installed, then check your version number looking in <boost/version.hpp>. See http://randspringer.de/boost for more documentation.
checking whether the Boost::Python library is available... no
configure: error: No usable boost::python found
I see no solution on the mailing list of graph-tool or stackoverflow about this problem. I would be really grateful if somebody could help me with this.
Thanks in advance.

In Debian, the libraries are almost always split in two packages: One
containing the shared object and another one with "-dev" suffix which
contains the header files. For cairomm you need to install the
libcairomm-1.0-dev package, in addition to libcairomm-1.0.
And cairo support is optional. If you want to disable it, just pass
the --disable-cairo to the configure script.

There are some issues with the boost package on ubuntu 14.04 and some of the graph-tool functions (see graph-tool - k-shortest path - boost::coroutine was not found at compile-time and http://main-discussion-list-for-the-graph-tool-project.982480.n3.nabble.com/Debian-package-and-boost-at-compile-time-td4026383.html ). At current it seems neccessary to compile boost from source until a newer version of boost is uploaded to the repository in order for graph-tool to work fully.
Once this bug is fixed (https://bugs.launchpad.net/ubuntu/+source/boost1.54/+bug/1529289) it will no longer be a problem.

Installing graph-tool on Mac OS X (10.7) - already have Boost installed, but keep getting this error

I've been stuck on this issue for a while now. I'm trying to install graph-tool - http://graph-tool.skewed.de/download#macos - and I have the prereqs from following these steps, which the graph-tool site links to: https://gist.github.com/openp2pdesign/8864593
Instead of brew install, which didn't seem to give me all the files, I went to Boost's official site and downloaded from there properly, following these steps: http://www.boost.org/doc/libs/1_41_0/more/getting_started/unix-variants.html It's mainly getting a tar file and untarring it.
I then put my boost install here:
/usr/local/boost_1_55_0
I did a small C++ example and confirmed Boost works (using "Build a Simple Program Using Boost" from http://www.boost.org/doc/libs/1_41_0/more/getting_started/unix-variants.html.
Now the meat of the problem: trying to install graph-tool. In the very last step, I do
./configure PYTHON_EXTRA_LDFLAGS="-L/usr/local/bin"
(The PYTHON_EXTRA_LDFLAGS="-L/usr/local/bin" just makes the configure script find Python alright.)
But I get this error. (It finds Python fine, but not boost!)

please specify $BOOST_ROOT in your environment and do not give a PATH to --with-boost option.
If you are sure you have boost installed, then check your version number looking in

Attempt 2: I then tried setting BOOST_ROOT properly:
In my ~/.bash_profile:
export BOOST_ROOT="/usr/local/boost_1_55_0"
But it still did no good, so I unset that.
Attempt 3: I then tried explicitly specifying where boost is installed:
./configure --with-boost="/usr/local/boost_1_55_0" PYTHON_EXTRA_LDFLAGS="-L/usr/local/bin"
But it still can't find boost, and yields that same error in the end of "We could not detect the boost libraries (version 1.38 or higher)."
It's been bugging me all day. I've read carefully, and went to the randspringer.de/boost site and saw this in the FAQ - http://www.randspringer.de/boost/faq.html#id2514912:
Q: I do not understand the configure error message
At configure time I get:
checking for boostlib >= 1.33... configure: error: We could not detect
the boost libraries (version 1.33 or higher). If you have a staged
boost library (still not installed) please specify $BOOST_ROOT in your
environment and do not give a PATH to --with-boost option. If you are
sure you have boost installed, then check your version number looking
in . See http://randspringer.de/boost for more
documentation.
I don't know if I use a staged version of boost. What is it and what
can I do ?
A: If you did not compile Boost by yourself you don't have a staged
version and you don't have to set BOOST_ROOT. Look here for an
explanation of different kind of installations.
If you are sure you have Boost installed then specify the directory
with
./configure --with-boost=your-boost-directory.
If it still does not work, please check the version number in
boost/version.hpp and compare it with the version requested in
configure.ac.
And I don't know what to see when comparing version numbers. There's nothing I found interesting there.
Hoping someone has at least an idea on what other approaches to take.

Hooray, my first chance to give back to Stack Overflow! I've been dealing with this issue myself the past 2 days.
Solution
Upgrade clang via Xcode
Make a symlink to boost that includes the version number
/usr/local/include/boost-1_55.0 -> ../Cellar/boost/1.55.0/include/boost
(included because I installed Boost using Brew and had this issue)
Edit the generation of CXXFLAGS in configure so that it looks like this:
old_cxxflags="$CXXFLAGS"
CXXFLAGS="${CXXFLAGS} -std=gnu++11 -stdlib=libc++"
{ $as_echo "$as_me:${as_lineno-$LINENO}: checking whether C++ compiler supports -std=gnu++11" >&5
$as_echo_n "checking whether C++ compiler supports -std=gnu++11... " >&6; }
Run
./configure --disable-sparsehash CXX="/usr/bin/clang++" PYTHON_EXTRA_LDFLAGS="-L/usr/local/bin"
Versions
OS: Mac OS X 10.8.5
Clang: Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
Target: x86_64-apple-darwin12.5.0
Thread model: posix
Graph-tool: 2.2.29.1
Boost: 1.55.0
Explanation
If you go through the configure code and try and compile the confdefs.h files made in configure, you'll see clang error out upon encountering the -Wno-unused-local-typedefs flag. This is the actual cause of the "We could not detect the boost libraries (version 1.33 or higher)" error, not the fact that it can't find the boost files. This issue is fixed with newer versions of clang.
The configure test for version number is goofy. It expects the boost include directory to contain the version number.
While running make, you may run into the following errors:
./../graph_adjacency.hh:26:10: fatal error: 'tuple' file not found
This is caused by referencing the wrong standard library [1]
./../graph_adaptor.hh:655:39: error: expected ';' in 'for' statement specifier
for(typeof(removed_edges.begin()) iter = removed_edges.begin();
./../graph_adaptor.hh:655:39: error: use of undeclared identifier 'tier'
This is caused by referencing the wrong C++ standard (c++11 instead of gnu++11)
References
[1] No member named 'forward' in namespace 'std'
[2] I'm having some trouble with C++11 in Xcode

I think that you're currently pointing --with-boost to the boost parent directory, not the boost libraries.
Try
./configure --with-boost="/usr/local/boost_1_55_0/libs/" PYTHON_EXTRA_LDFLAGS="-L/usr/local/bin"

Basic Vim Installation, from Source Code

Tried installing Vim 7.3 so I first installed Mercurial, which allowed me to clone vim source code off Googlecode. This was done successfully.
Problem started from here:
cd vim/src
./configure --enable-pythoninterp --with-features=huge -prefix=$HOME/opt/vim
which drew this response from the terminal:
configure: loading cache auto/config.cache
checking whether make sets $(MAKE)... no
checking for gcc... no
checking for cc... no
checking for cl.exe... no
configure: error: in `/Users/JayEdge/vim/src':
configure: error: no acceptable C compiler found in $PATH
See `config.log' for more details.
Tried looking at config.log (in my case it was auto/config.log) but I'm not sure what to look out for.
Background: I've checked that Xcode is installed properly, and gcc.vim was found inside the route vim/runtime/compiler. Should I move this (or duplicate this) into another folder? If so, which folder to move it into?

Like Karoly said, you need a c compiler. Since it looks like you are running OSX (based on your xcode comment I would suggest grabbing the OSX-GCC installer at the following site:
https://github.com/kennethreitz/osx-gcc-installer
I would also look into grabbing homebrew for installing things like vim.
Cheers,
Sean

no acceptable C compiler found in $PATH
That's a pretty clear error message, you need to install a compiler, if you haven't done sone.
Install gcc.
If you already installed gcc you have to add the path so configure can find it, eg:
export PATH="$PATH:/usr/bin"

Problem has been solved and here's to share with anyone if they have the same problems, specifically for people who install xCode via the app store after March 2012. (Credits to my Python Mentor, Martin)
Xcode from the app store currently only allows you to download the IDE, which is not what we want. What we want is the Apple Developer Tools, which you can get via https://developer.apple.com/xcode/ after signing up as a Apple Developer. Search for "Command Line Tools, late March 2012", install it and the configure command earlier should work properly.
Otherwise, you may refer to Sean's answer earlier.
FYI, I do intend to install homebrew but as a beginner, compiling it from source code is a great way of picking up some basics, interact with some basic syntax (or learn to parse them).

you can try it:
yum install gcc
