Coin3D & QT on Ubuntu12.10

這篇內容是如何建構開發環境!

OS: ubuntu 12.10 32bit

1. 安裝開發套件：

sudo apt-get install build-essential
sudo apt-get install libqt4-dev
sudo apt-get install libcoin60
sudo apt-get install libsoqt4-dev

2. 撰寫sample code

#include <Inventor/Qt/SoQt.h>
#include <Inventor/Qt/viewers/SoQtExaminerViewer.h>
#include <Inventor/nodes/SoBaseColor.h>
#include <Inventor/nodes/SoCone.h>
#include <Inventor/nodes/SoSeparator.h>

int main(int argc, char ** argv)
    {
    printf("hello");
    // Initializes SoQt library (and implicitly also the Coin and Qt
    // libraries). Returns a top-level / shell Qt window to use.
    QWidget * mainwin = SoQt::init(argc, argv, argv[0]);

    // Make a dead simple scene graph by using the Coin library, only
    // containing a single yellow cone under the scenegraph root.
    SoSeparator * root = new SoSeparator;
    root->ref();

    SoBaseColor * col = new SoBaseColor;
    col->rgb = SbColor(1, 1, 0);
    root->addChild(col);

    root->addChild(new SoCone);

    // Use one of the convenient SoQt viewer classes.
    SoQtExaminerViewer * eviewer = new SoQtExaminerViewer(mainwin);
    eviewer->setSceneGraph(root);
    eviewer->show();

    // Pop up the main window.
    SoQt::show(mainwin);
    // Loop until exit.
    SoQt::mainLoop();

    // Clean up resources.
    delete eviewer;
    root->unref();
    SoQt::done();

    return 0;
}

3.compile

產生project (QT.pro)

qmake -project

產生Makefile

qmake

compile

make

這時候會產生make error
是因為qmake產生Makefile沒有去做SoQT 和 Coin3D的動態連結

4 修改Makefile

在 LIBS後面加 -lSoQt -lCoin

LIBS = $(SUBLIBS)  -L/usr/lib/i386-linux-gnu -lQtGui -lQtCore -lpthread -lSoQt -lCoin

5 finish

make
./QT
