maybe its time for a shameless plug one more time:

   http://pear.php.net/package/CodeGen_PECL/docs

this approach will shield you from autoconf/make details as
much as possible, it will also generate windows VS 6.0 .dsp
project files, too

its not mentioned in the above docs, but compiling the generated
extension code staticly into PHP just requires these simple steps:

  - place the generated code directory into PHPs ext/ directory
  - run buildconf (in the top level src directory)
  - if you've already built php from this source tree before do

     config.nice ...any-options-specific-to-your-extension

    else extract the configure string for the current php installation
    from "php -i" output, re-use this configure line and add your
    extensions options to it
  - make
  - optional: make test
  - make install (may require sudo)

i don't know / use Kdevelop, but i'm pretty sure that it allows
to integrate standard unix projects based on configure/make ...

using CodeGen_PECL you'll get a full self contained extension
project, including a package.xml file suitable for automatic
installation using the pear installer
