我指的是https://llvm.org/docs/GettingStarted.html从其源代码构建 LLVM。我使用的是 Ubuntu 18.04。

$ cmake -G Ninja -DCMAKE_BUILD_TYPE=RelWithDebInfo ../llvm
$ cmake --build .

以下是错误：

我的目标是从两个文件中读取数据并比较数据。我的输入文件是result3.json和result4.json。这些文件中的数据是逗号分隔的。

结果3.json

[
  "temp1.txt",
  "temp2.txt",
]

节点：

function readFromFile(file) {
    var fileNames = [];
    //setTimeout(function() {
        fs.readFile(file,function(err, data){
            if (err) {
                return console.log(err);
            }
            var temp = JSON.parse(data.toString().split(","));
            // console.log(temp.length);
            for (let index = 0; index < temp.length; index++) {
                //console.log(temp[index]);
                fileNames.push(temp[index]);
                //console.log(fileNames[index]);
            }
            Done(); // to block the async call
        });
        //},3000);
    //console.log(fileNames.length);
    return fileNames;
}

var baseListOfFiles = readFromFile('./output/result3.json'); // Assume this is the base file
var currentListOfFiles = readFromFile('./output/result4.json'); // Assume this is the current file

function …
