Question

我正在尝试使用一些示例代码与OpenMS愉快地工作并遇到很多麻烦。我有（只是一个小样本程序，作为一个例子）：

#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;
}

我编译它：

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

它出现了一大堆错误（实际上约为500Kb）。问题似乎在于“使用命名空间OpenMS;”一小部分错误：

      OpenMS::Internal::MzMLHandler<OpenMS::MSExperiment<OpenMS::Peak1D, OpenMS::ChromatogramPeak> >::handleUserParam_(OpenMS::String const&, OpenMS::String const&, OpenMS::String const&, OpenMS::String const&, OpenMS::String const&)in cc7cSzjW.o

有没有人能够了解我做得不对？

Answer 1

尝试将其编译为目标文件（ - c），然后查看问题是否仍然存在。 E..g。：这是编译问题还是链接问题？

另外：是否应该有 -L 标志来搜索特定的库路径？是否应该在特定库中链接 -l </ strong>标志？

使用OpenMS命名空间时出现未定义的符号问题
