installed the ogre packages... now what?

[Choad]

to clarify, c++ isn't my strong point. i am just trying to get to the point where i can compile an example app.

bla.cpp

#include "ExampleApplication.h"

class TutorialApplication : public ExampleApplication
{
protected:
public:
TutorialApplication()
{
}

~TutorialApplication()
{
}
protected:
void createScene(void)
{
}
};

#if OGRE_PLATFORM == OGRE_PLATFORM_WIN32
#define WIN32_LEAN_AND_MEAN
#include "windows.h"

INT WINAPI WinMain( HINSTANCE hInst, HINSTANCE, LPSTR strCmdLine, INT )
#else
int main(int argc, char **argv)
#endif
{
// Create application object
TutorialApplication app;

try {
app.go();
} catch( Exception& e ) {
#if OGRE_PLATFORM == OGRE_PLATFORM_WIN32
MessageBox( NULL, e.what(), "An exception has occurred!", MB_OK | MB_ICONERROR | MB_TASKMODAL);
#else
fprintf(stderr, "An exception has occurred: %s\n",
e.what());
#endif
}

return 0;
}

makefile

DEFINES =
LIBS = OGRE
CXX = g++
CXXFLAGS = $(shell pkg-config --cflags $(LIBS)) $(DEFINES)
LD = g++
LDFLAGS = $(shell pkg-config --libs $(LIBS))

all:
$(CXX) $(CXXFLAGS) $(LDFLAGS) -o bla bla.cpp

clean:
rm -f bla


terminal output


make

any help? gotta set up some environment variables? does the packaged ogre not come with this file?

It appears as if you forgot to copy the "ExampleApplication.h" header file from your tutorial (into the same directory as your code file).

Hint: Always look at the *first* error the compiler produces. The rest might be caused by the first one, so fix it first. In this case, it is:


bla.cpp:1:32: error: ExampleApplication.h: No such file or directory

i'm pretty sure that stuff is part of ogre tho. well anyway...

ok so i downloaded the source to get a copy of exampleApplication.h

stuck it in and then...

??

i'm guessing i now need ois/ois.h

i have simply never been able to get my head around c++ development. :(

with python, you type import <module> and it works. do the same in c++ and you spend the next week trying to figure out what the hell is going wrong! (i do want to learn tho)

well ok i got bored of trying to find out wtf OIS is called in synaptic so i just compiled it from source.

now i get a slightly different error but it's still talking about OIS
