在CMamke生成的VS项目中插入程序

1. 在主文件夹的CMakeLists.tex中加入SET(COMPILE_WITH_LSVM OFF CACHE BOOL "Compile with LSVM")
   
   再添加IF(COMPILE_WITH_LSVM) MESSAGE("Compiling with: LSVM") ADD_DEFINITIONS(-DCOMPILE_WITH_LSVM) ADD_SUBDIRECTORY(LSVM) LIST(APPEND SRC LSVM_wrapper.h LSVM_wrapper.cpp) ENDIF()

之后再按CMake添加程序
把该加的都加进主文件夹和子文件夹中的CMakeLists.tex里
都加好之后再用Cmake congfigure就会出现我们新加的程序，在value列上打上对号，再congfigure

2. 在VS中添加
   一个头文件：LSVM_wrapper.h

#pragma once#include "svm_template.h"class LSVMData : public SvmData
{
public:int Load(char *filename, SVM_FILE_TYPE file_type, SVM_DATA_TYPE data_type);
};class LSVMModel : public SvmModel
{
public:int Train(SvmData *data, struct svm_params * params, struct svm_trainingInfo *trainingInfo);int StoreModel(char *model_file_name, SVM_MODEL_FILE_TYPE type);
};

和一个源文件：LSVM_wrapper.cpp

#include "ohdSVM_wrapper.h"
#include "OHD-SVM/ohdSVM.h"
#include "utils.h"
#include <string>extern int g_ws_size;
extern std::string g_imp_spec_arg;int ohdSVMData::Load(char *filename, SVM_FILE_TYPE file_type, SVM_DATA_TYPE data_type)
{svm_memory_dataformat req_data_format;req_data_format.allocate_pinned = false;req_data_format.allocate_write_combined = false;req_data_format.dimAlignment = 32;req_data_format.vectAlignment = 32;req_data_format.transposed = false;req_data_format.labelsInFloat = true;req_data_format.supported_types = SUPPORTED_FORMAT_DENSE | SUPPORTED_FORMAT_CSR;  //no sparse yetSAFE_CALL(SvmData::Load(filename, file_type, data_type, &req_data_format));//filename=argv[1]=a9a.txt,file_type = LASVM_BINARYreturn SUCCESS;
}int ohdSVMModel::Train(SvmData *data, struct svm_params * params, struct svm_trainingInfo *trainingInfo)
{this->data = data;this->params = params;alphas = (float *)malloc(data->GetNumVects() * sizeof(float));float rho = 0;try{size_t pos = g_imp_spec_arg.find(',');if (pos != std::string::npos){int sliceSize = atoi(g_imp_spec_arg.c_str());int threadsPerRow = atoi(g_imp_spec_arg.c_str() + pos + 1);ohdSVM::useEllRT(true, sliceSize, threadsPerRow);}bool is_sparse = data->GetDataType() == SVM_DATA_TYPE::SPARSE;ohdSVM::Data x;if (is_sparse)x.sparse = (ohdSVM::csr *)data->GetDataSparsePointer();elsex.dense = data->GetDataDensePointer();ohdSVM::Train(alphas, &rho, is_sparse, x, (const float *)data->GetVectorLabelsPointer(),data->GetNumVects(), data->GetNumVectsAligned(),data->GetDimVects(), data->GetDimVectsAligned(),params->C, params->gamma, params->eps, g_ws_size);}catch (std::exception & e){std::cerr << "Exception in OHD-SVM: " << e.what() << std::endl;}params->rho = rho;SAFE_CALL(CalculateSupperVectorCounts());return SUCCESS;
}int ohdSVMModel::StoreModel(char *model_file_name, SVM_MODEL_FILE_TYPE type)
{return StoreModelGeneric(model_file_name, type);
}

3. 在svm-train.cpp中加入

#ifdef COMPILE_WITH_LSVM
#include "LSVM_wrapper.h"
#endif

添加

	#ifdef COMPILE_WITH_LSVMcase 17:printf("Using LSVM...\n\n");data = new LSVMData;model = new LSVMModel;return SUCCESS;
#endif
