为什么Eclipse 4.7.2 Release Build：4.7.2现在没有delta包下载？
我如何为eclipse-4.7.2创建delta-pack？ 如果有人有这个想法，请建议我......
答案 0 :(得分：3)
自 Eclipse 4.5 ， DeltaPack is no longer available。
解决方案1：
目前执行多平台构建的首选方法是将目标平台设置为适当的Eclipse存储库。有关详细信息，请参阅here。
解决方案2：
可以构建自己的Eclipse DeltaPack。
例如，您可以使用Eclipse's git repository中的ant脚本在IDE中执行DeltaPack来创建#include <iostream>
#include <string>
#include <fstream>
#include <stdio.h>
#include <vector>
#include <math.h>
using namespace std;
vector<unsigned char> header;
vector < vector<unsigned char> > img;
short int width = 0;
short int height = 0;
void read(string filename, short int &width, short int &height, vector < vector<unsigned char> > &img, vector<unsigned char> &header)
{
const char* path = (char*)filename.c_str();
cout << endl << "Opening: " << path << endl << endl;
ifstream inputfile;
inputfile.open(path, ios::binary);
inputfile.seekg(0);
if (!inputfile)
{
inputfile.clear();
string pathin;
cout << "File not found "<< endl <<"Enter name of image to open : ";
getline(cin, pathin);
read(pathin, width, height, img, header);
}
else
{ //copy header into array
unsigned char h = 0;
for (int x = 0; x < 5; x++)
{
inputfile >>(h);
header.push_back(h);
}
//extract width and height from array
width = (header[1]<<8 | header[0]);
height = (header[3]<<8 | header[2]);
//copy image data into array
char a = '0';
for (int x = 0; x < width; x++)
{
vector <unsigned char> row;
for (int y = 0; y < height; y++)
{
inputfile.get(a);
row.push_back(a);
a = '0';
}
img.push_back(row);
}
inputfile.close();
}
return;
