[portets]

Ubuntu package name is libcurl4-gnutls-dev

thanks , did the job. but now i get:

You need glew >= 1.5.4 for the GL3.3 pieces.

[portets]

oops.. 8)

i should have looked at the previous posts to see that someone had that error already.

Why did you remove the "virtual" tag from drawEnabled?

Assumed there would be no classes derived from RenderModelExternalDrawable. Else might be a good idea to make the destructor virtual too.

But... RenderModelExternalDrawable is a derived class. It derives from RenderModelExternal. If I want to call drawEnabled on a base class (RenderModelExternal) pointer and have the RenderModelExternalDrawable drawEnabled method get called, RenderModelExternalDrawable::drawEnabled must be virtual too, right? It doesn't really matter because due to some other changes RenderModelExternalDrawable::drawEnabled no longer exists, but I'm curious.

[NaN]

Declaring a method virtual tells the compiler to look for it in the vtable. Try:

Code:

#include <iostream>

class Base
{
public:
    virtual void print() {
        std::cout << "base" << std::endl;
    }
};

class Derived : public Base
{
public:
    void print() {
        std::cout << "derived" << std::endl;
    }
};

int main() {
    Base a;
    Derived b;
    Base * c = &b;
    a.print();
    b.print();
    c->print();
    return 0;
}

[joevenzon]

Oh cool, thanks. It makes sense now.

Guys, is windows build broken or i missed something?

I've downloaded latest glew, rearranged files and now i'm getting:
"obj\Release\src\ai.o:ai.cpp|| undefined reference to `vtable for RenderModelExternalDrawable'|" etc

[NaN]

Project file needed to be updated.

finally got glew 1.5.8 installed. a friend said it might be good to put it in my /usr/local directory. after that it compiled. but won't link:

i still have the normal ubuntu10.10 glew around(1.5.0 i think). which i can't remove (via synaptic) without taking out gnome too. i know, i know, no real loss, but i don't have a good version of e17 on here yet.

anybody got any ideas?

[fudje]

anybody got any ideas?

Did you clean your vdrift tree before rebuilding?
It might also be necessary to trash SCons's cache - do 'rm .sconsign.dblite' from the vdrift directory.

Add this ppa, then update via synaptic. You'll have 1.5.6 properly installed.

[zimluura]

fudje: on your advice, i tried it. still wouldn't link same error i think.

skankerror: the ppa version got it to link, and now all is well.


thanks to both of you for the helpful suggestions!

[portets]

just tried the gl3 and get a black screen and segfault after "Loaded GUI successfully".

rv3076 datarv806, nvidia 9600m gs on 260.19.06 that reports gl3.3 capabilities.

Ubuntu 10.10 for amd64, vdrift rev. 3076.
I have tried to delete ~/.vdrift and restart but nothing. Also I have tried to compile and install latest glew from svn repository.

[gianni]

If it can be usefull, this is my output from gdb:
