Hi,
I try to compile a fltk2 program with a GlWindow element, with Code::Blocks,
under Ubuntu. This program compiled correctly under my last system (Debian) and
under Windows with Dev-cpp. But after installing fltk-2.0.x-r6525 and OpenGl
libraries, I have still a linking problem. It's look like the compiler doesn't
find the fltk2_gl library whereas it's linked. I put below the part of the code
with errors and the compilation results.
mainWindow.glWindow->mode(DOUBLE_BUFFER | DEPTH_BUFFER | STENCIL_BUFFER |
RGB24_COLOR | ACCUM_BUFFER);
mainWindow.glWindow->listeRobots=listeRobots;
mainWindow.glWindow->listeObstacles=listeObstacles;
mainWindow.glWindow->listeObstacles=listeObstacles;
mainWindow.glWindow->nbCases=nbCases;
mainWindow.glWindow->longueurCases=dimCases;
mainWindow.glWindow->additionalDisplay=&affichageSupplementaire;
mainWindow.glWindow->action=&action;
mainWindow.doubleWindow->show();
glwindow is an instance of a MyGlWindow class is derived from fltk::GlWindow
class.
And the result of the compilation is :
obj/Debug/main.o||In function `main':|
main.cpp|792|undefined reference to `fltk::GlWindow::mode(int)'|
obj/Debug/mainWindow.o||In function `fltk::GlWindow::GlWindow(int, int,

If you have an idea about the problem...
Thanks in advance for your answers and please sorry for my really not fluent
english...
