[Gluster-devel] Change in glusterfs[master]: configure.ac: build glupy with installed python

[Anand Avati]

Ram Raja, Kaleb,
  This patch is "almost" right. However I think we need an extra 
AC_CHECK_HEADERS[Python.h]. This is because on systems where 
python-devel RPM is missing, BUILD_PYTHON_INC successfully gets set even 
though headers are not installed (that BUILD_PYTHON_INC variable is the 
location of where the headers will be, if at all. It does not guarantee 
the headers are actually installed).

Also please provide a way to disable glupy build. I was pretty much 
stuck (i.e, when python installed, python-devel not installed). As with 
all other autoconf tunables in our configure.ac, please use the 
following strategy:

- If neither --enable-<feature> nor --disable-<feature> is specified, 
auto detect availability of dependencies (Python.h, etc.) and decide.
- If --disable-glupy is specified, do not build even if dependencies 
might be met.
- If --enable-glupy is specified, check for dependencies and fail the 
configure script if unmet.
- Print the decision in the "configure summary" at the end in any case 
(unless script was failed in step 3)

This is the standard pattern followed in pretty much all the 
sub-sections of configure.ac and we need to stay uniform in this aspect.

Thanks!
Avati
