I'm running centos 6.0 Using python 2.7 and boost 1.44 installed numpy scipy, expat and other dependencies when I run configure ./configure --prefix=/opt LDFLAGS=-L/opt/lib CPPFLAGS=-I/opt/include CXXFLAGS=-I/opt/include I am producing an error: (I have Python.h installed since I compiled python2.7 from source) checking consistency of all components of python development environment... no configure: error: Could not link test program to Python. Maybe the main Python library has been installed in some non-standard library path. If so, pass it to configure, via the LDFLAGS environment variable. Example: ./configure LDFLAGS="-L/usr/non-standard-path/python/lib" ============================================================================ ERROR! You probably have to install the development version of the Python package for your distribution. The exact name of this package varies among them. ============================================================================ -- View this message in context: http://main-discussion-list-for-the-graph-tool-project.982480.n3.nabble.com/...
