				This is from gnozal at http://www.purebasic.fr/english/viewtop ... 13&t=47397 which appears to originate from http://pbasic.spb.ru/phpBB3ex/viewtopic ... ebfabbff76
I try running with F5 and get "OCI ERROR 0 (Cannot load OCI symbols from shared library)". I have libocilibw.a and set temp executable to same directory as source along with ocilibw.dll and ocilibw.lib. Do I have to set environment variables somewhere? I'm am only starting to use libraries and such. Please point me in the right direction.
From the OCILIB site under Download > "Installation":
copy ocilib\include\ocilib.h to any place located in your include’s path ( It's not in gnozal's example. Is this necessary?)
copy ocilib\lib32|64\ocilib[x].lib to any place located in your libraries path (does this mean C:\Program Files (x86)\PureBasic\PureLibraries\UserLibraries or \Windows\Libraries ?)
copy ocilib\lib32|64\ocilib[x].dll to any place located in your windows path (C:\Windows\System32 or same location as source?)
