error while including "dbpolyline.h"

error while including "dbpolyline.h"
hi all,
i've developed an mfc application for viewing and processing dwg files using dwgdirect 1.11.01.
for retrieve the coordinates for acdbpolyline entity, i included the header file 'dbpolyline.h' for getting the oddbpolylineptr, it show the following error.
ex\db2dpolyline.h(60) : error c2555: 'oddb2dpolyline::setcolor' : overriding virtual function differs from 'oddbentity::setcolor' only by return type or calling convention
ex\dbentity.h(49) : see declaration of 'oddbentity'
ex\db2dpolyline.h(69) : error c2555: 'oddb2dpolyline::setcolorindex' : overriding virtual function differs from 'oddbentity::setcolorindex' only by return type or calling convention
ex\dbentity.h(49) : see declaration of 'oddbentity'
ex\db2dpolyline.h(71) : error c2555: 'oddb2dpolyline::settransparency' : overriding virtual function differs from 'oddbentity::settransparency' only by return type or calling convention
ex\dbentity.h(49) : see declaration of 'oddbentity'
can anyone say the solution for this.
thanks & regards,
rajesh parameswaran.

it seems you are using mixed headers from 1.10 and 1.11.
oddbentity.h from one version and db2dpolyline.h from another.
between 1.10 and 1.11 return value of listed functions changed from void to odresult.

lib or dll configuration of dd? debug or release? are precompiled headers enabled? did you try rebuild all?

hi george & sergey,
yes, problem was solved. you are right. this is because of the header file version conflict. i used both 1.11.0 and 1.11.01. now the problem was solved.
thank you !!!!!!!!!
