使用OpenMS命名空間時未定義的符號問題

我試圖讓一些示例代碼與OpenMS一起愉快地工作，並且遇到了很大的麻煩。我有（即發貨作爲例子只是一個小樣本程序）：使用OpenMS命名空間時未定義的符號問題

#include <OpenMS/FILTERING/SMOOTHING/GaussFilter.h> 
#include <OpenMS/FORMAT/MzMLFile.h> 
#include <OpenMS/KERNEL/StandardTypes.h> 
#include <stdio.h> 

using namespace OpenMS; 
using namespace std; 

Int main(){ 
    PeakMap exp; 

    MzMLFile mzdata_file; 
    mzdata_file.load("../sampledata_Centroidmode.mzML",exp); 

    GaussFilter g; 
    Param param; 
    param.setValue("gaussian_width",1.0); 
    g.setParameters(param); 

    g.filterExperiment(exp); 

    return 0; 
}

我編譯：

g++ -Wall -IOpenMS-1.7.0/include -IOpenMS-1.7.0/contrib/include -I/Library/Frameworks/QtCore.framework/Headers -arch i386 scratch.cpp

它有錯誤的一大堆（其中約〜500KB大作，竟）。問題似乎在於「使用命名空間OpenMS;」這些錯誤的小樣本：

    "OpenMS::DataValue::DataValue(int)", referenced from:

...

沒有人有洞察力，以什麼我不這樣做對嗎？

嘗試將其編譯爲目標文件（-c）並查看問題是否仍然存在。 E .. g .:這是一個編譯問題或一個鏈接問題？

另請參見：應該有-L標誌來搜索特定的庫路徑？是否應該有一個-l標誌鏈接在特定的庫？

哦，很好的電話。我已經添加了OpenMS庫，但我認爲我仍然需要Qt - Qt庫通常安裝在哪裏？ – sbirch 2010-11-07 22:00:54

我認爲默認是/ usr/local/Trolltech/Qt- $ VERSION /，但我可能被誤認爲... – 2010-11-08 03:10:56

我實際上找到了另一種方法（Ree先生的方法也可能工作）。我用qmake -project編輯了.pro文件：（INCLUDEPATH + = OpenMS-1.7.0/include INCLUDEPATH + = OpenMS-1.7.0/contrib/include unix：LIBS + = OpenMS-1.7.0/contrib/lib unix：LIBS + = OpenMS-1.7.0/lib -lOpenMS）並使用qmake -makefile -spec macx-g ++/make。 – sbirch 2010-11-08 04:22:02
