dravim, pri vytvarani okna pre OpenGL mi vzdy po zacati komplicie vybehne chyba...

za rady dakujem smiling smiley

sak este sa ta to pyta: tak ho tam skus pridat

taky sprosty niesom, ked tam vlozim stdafx, vypise mi 25 chyb v syntaxe. BTW, toto mi vypisuje takmer pri vsetkom.

popripade nemate nejaky dobry opne gl zdojak pre vytvorenie zalkadneho okna?


//edit :zistil som, ze mi to pise takmer pri vsetkych programoch.

Project -->> Settings ->>
vyber si trebars Release verziu;
vybel si prislusny *.cpp
-- >> Zalozka C/C++ -->> Category: Precompiled Headers:
.... tam si skus dat volbu: Not using precompiled headers; (pripadne skus aj inu volbu)

Vacsinou ten problem nastane, ak tam pridas novy subor nejakym nestandardnym sposobom, alebo potrebuje este nejaky makropreklad.
