gametutorials.com

its all there, just take a look around

Can anyone please try compiling it and explaining me those

Thanks in advance

Presumably just a typo, but it's cone3d.gamedev.net

okay here are the errors i am getting
I am using glut32.dll and cygwin1.dll
anyone wanna have a look



one3dtga.cpp
error C4716: ''Cone3DOctree::toggleWirez'' : must return a value
error C4716: ''Cone3DOctree::setPolyz'' : must return a value
error C4716: ''Cone3DOctree::Draw'' : must return a value
error C2057: expected constant expression
error C2466: cannot allocate an array of constant size 0
error C2133: ''comment'' : unknown size
error C2070: illegal sizeof operand

these error messages are quite self-explanatory :

error C4716: ''Cone3DOctree::toggleWirez'' : must return a value
check the declaration of the method toggleWirez of the class Cone3DOctree ... according to this error message, the compiler expects a return statement in the method...

error C4716: ''Cone3DOctree::setPolyz'' : must return a value
same as above

error C4716: ''Cone3DOctree::Draw'' : must return a value
idem

error C2057: expected constant expression
error C2466: cannot allocate an array of constant size 0
i think these two errors are linked together, ie the second one will disappear if you correct the first one ... it seems that somewhere in the code a const or #define statement is fucked up so that it evaluates to 0, and then later when the array is allocated with this constant expression it tries to allocate 0 bytes of memory ... surely a typo at the line specified by the first error

error C2133: ''comment'' : unknown size
error C2070: illegal sizeof operand
i can''t extrapolate from these two error messages, you should look into the code there, and try to understand ...


by the way i''d like to point out that you seem to not understand some basic error reportings, thus i can extrapolate that you need some more C/C++ learning before trying to get into graphics programming ... or try another language yhou understand more ...

c ya,

The last message pretty much covers it -

However, without looking at the code I am going to go out on a limb and guess the error C4716 were because you forgot to specifically declare a return of void. If nothing is specified ( which can easily be mistaken for "dont return anything" ) it defaults to returning int - or at least most compilers will with the default options. In that case you get the error because the function was never intended to return anything.

Hope that helps a little -

Ok thanks a lot
I know all about what int and void
anyway I thought that it was a full working code which seems not to be the case
anyway I will have to check the entire code to make it work
thanks for the comments anyway
