<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">This question may have been asked already, but I could not find a definitive answer in the mailing list. I would like to build a shared object version of pnetcdf so I can link it
to the IOR benchmark. I know a static version is faster, but a shared object file will allow me to profile IOR, so that is the reason why. Any help will be greatly appreciated. I could not find any configure flags for pnetcdf to allow me to build a shared
object version of the library. <o:p></o:p></p>
