An affiliate user reported the following:
I tried using the Windows ruby driver (cubrid-0.61-x86-mingw32), but it won't load. It brings up a Windows dialog box stating: 'The procedure entry point cci_glo_new could not be located in the dynamic link library cascci.dll'.
Basically, it appears to be compiled against a different version of CUBRID than the current Windows download, so it doesn't work.
