Could not find a task generator for the name 'six-python'

[JBUserGame]

I'm trying to build ngaSix. I did this successfully a few months ago, but now the install is complaining. I possibly installed a new version of python in the interim. I first did this:

  `  ./waf configure --prefix=install

`
That seemed to be successful. But then the install failed:

./waf install --targets=six-python
Waf: Entering directory `/home/userjb/src/ngaSIXLibrary/target'
Waf: Leaving directory `/home/userjb/src/ngaSIXLibrary/target'
Could not find a task generator for the name 'six-python'

What am I doing wrong?

Can you post the output of the waf configure command here? My guess is that waf is either not finding Python at all or doesn't like something about it. When it can't build the Python bindings, it doesn't add the Python targets in which I think is why it can't find a task generator for it.

Here are the relevant parts of the output of 'waf configure'

I'm using a locally installed version of python so it's quite possible something isn't right.

Thanks for the log.

Yeah you can take a look at /home/userjb/src/Work/Software/ngaSIXLibrary/target/config.log to get a little more detail (you'll see waf actually trying to compile the various things that are failing and see the compiler/linker errors). I'm betting that you'll see a linker error; if that locally installed Python is one you built from source, Python doesn't build with PIC by default. You'll want to rebuild your Python and in its configure step use --with-pic (I think that's the configure option).

It looks like I have two separate errors in the config.log. They happen close together. The first is:
err: g++: error: unrecognized command line option '-fp-model'
The second is a g++ compile command that is defining

    -DPYTHONDIR="/home/userjb/src/ngaSIXLibrary/install/lib/python2.7/site-packages
    -DPYTHONARCHDIR="/home/userjb/src/ngaSIXLibrary/install/lib/python2.7/site-packages

The error message is
not found
It advises:
try again with -L$python_LIBPL (some systems don't install the python library in $prefix/lib)
But that isn't a waf command-line option. How can I tell waf where the python libraries are?

[JBUserGame]

I recompiled python with -fPIC (setenv CFLAGS "-fPIC") and the ngaSIX install was successful. Thanks for helping with this.

OK great!
