Setup G3D app with Makefile

[bcallebaut]

Hello,
I am starting up using G3D (version 7.01 compiled from source ).
To start a use de starter app (App.cpp/App.h). I need to compile the
app using a makefile and g++.
The reason is:
* the final application will be integrated with other libraries
* final application will be multi platform (MAC OSX/Windows/
Linux...)

I tried to compile the app under Linux (Ubuntu 8.10) using command
line and a CodeBlocks project.
cmdline command :g++ -o App -I /usr/local/include -L/usr/local/lib -
lG3D -lGLG3D -lzip App.cpp
I have linking problems :
here is a snap of the command line build:

eCountedPointer<G3D::Lighting> const&,
G3D::ReferenceCountedPointer<G3D::ShadowMap>)'
App.cpp:(.text+0x2a9): undefined reference to
`G3D::RenderDevice::pushState()'
App.cpp:(.text+0x2b4): undefined reference to
`G3D::RenderDevice::enableLighting()'
App.cpp:(.text+0x2f0): undefined reference to
`G3D::RenderDevice::setLight(int, G3D::GLight const&)'
App.cpp:(.text+0x343): undefined reference to
`G3D::RenderDevice::setAmbientLightColor(G3D::Color3 const&)'

Same kind of thing happens with codeblocks:

ToneMap.cpp:(.text+0x2149)||undefined reference to `G3D::GImage::GImage
(int, int, int)'|
ToneMap.cpp:(.text+0x21b6)||undefined reference to

Could someone help me ?

You need to fix your linking order. Dependencies need to be linked
first, then the libraries containing the dependencies.
