I had no problem building python for cygwin. I think your problem is that you also installed python for Windows (outside cygwin) and it comes first in your PATH variable.
You could either remove C:\Python25 from your PATH variable or after running configure open user-config.jam and replace using python line by using python : 2.5 : /usr ;

Hello all,
I am trying to install the Boost.Python library (and then compile C++ python extensions after that) using cygwin and am not having much luck. I know I have the main part of boost working because I was
able to compile and run the basic example for testing the boost configuration. Then to install Boost.Python I did the following:
$ ./configure –with-libraries=python
This generates the following output:
Building Boost.Jam with toolset gcc... tools/jam/src/bin.cygwinx86/bjam
Detecting Python version... 2.5
Detecting Python root... c:\Python25
Unicode/ICU support for Boost.Regex?... not found.
Backing up existing Boost.Build configuration in user-config.jam.2
Generating Boost.Build configuration in user-config.jam...
Generating Makefile...
I then type “make install”, which generates the following output:
./tools/jam/src/bin.cygwinx86/bjam --user-config=user-config.jam --prefix=/usr/local --exec-prefix=
/usr/local --libdir=/usr/local/lib --includedir=/usr/local/include --with-python install
WARNING: No python installation configured and autoconfiguration
failed. See http://www.boost.org/libs/python/doc/building.html
for configuration instructions or pass --without-python to
suppress this message and silently skip all Boost.Python targets
warning: Python location is not configured
warning: the Boost.Python library won't be built

...found 7812 targets...
Those warnings look rather problematic. And indeed, when I try to compile the basic example (/boost_1_34_0/libs/python/example/tutorial) by typing “bjam target-os=cygwin toolset=gcc”, I get the
following errors:
Jamroot:17: in modules.load

/cygdrive/p/c_libs/boost_1_34_0/libs/python/example/boost-build.jam:7: in module scope
Any ideas? Am I missing something obvious? Any help would be greatly appreciated. Thanks,
