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
I suggest you start by following the directions at http://www.boost.org/libs/python/doc/building.html. In particular, try adding --debug-configuration to your bjam options to see what's going on. To get that with configure, it looks like one sets the option in the BJAM_CONFIG shell variable. In bash: BJAM_CONFIG=--debug-configuration ./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
Like the other poster implied, it appears the system is finding your non-cygwin Python installation. That's the downside of using the configure script: it isn't as smart as the bjam python toolset ;-)
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
warning: Unable to construct ./install-unversioned
<schnipp>
...found 7812 targets...
Those warnings look rather problematic.
Those are outside my domain of expertise :(
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:
If building from the cygwin bash prompt with a cygwin-compiled bjam, you shouldn't need to specify the target-os.
Jamroot:17: in modules.load
rule python-extension unknown in module Jamfile
Any ideas? Am I missing something obvious? Any help would be greatly appreciated. Thanks,
I don't know a about the tutorial example in libs/python/example/tutorial, but the one in libs/python/example/quickstart needs the following patch: -- Dave Abrahams Boost Consulting http://www.boost-consulting.com The Astoria Seminar ==> http://www.astoriaseminar.com
