<p class="MsoNormal">Hi,<u></u><u></u></p>
<p class="MsoNormal"> <u></u><u></u></p>
<p class="MsoNormal">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. <u></u><u></u></p>
