Question

我想从Ubuntu 16.04计算机将OpenCV从3.2.0升级到3.4.3。我正在尝试删除OpenCV 3.2.0作为第一步（否则，我想并行安装另一个版本会是个坏主意吗？）。由于是从源代码安装的，因此我进入了构建目录并执行了sudo make uninstall。短时间后，该过程将失败并显示

-- Configuring incomplete, errors occurred!

Makefile:10212: recipe for target 'cmake_check_build_system' failed
make: *** [cmake_check_build_system] Error 1

读取的错误日志条目（第一个，但其他相似）：

如here所述，我尝试用-Wmissing-prototypes注释掉这一行，但没有效果。

该错误表明cmake无法从var objectarray=[]; var customer={ name,address,postalcode,phone,email} function addToArray() { var customerobject={name,address,postalcode,phone,email}; customerobject.name=document.getElementById("name").value; customerobject.address=document.getElementById("address").value; customerobject.postalcode=document.getElementById("postalcode").value; customerobject.phone=document.getElementById("phone").value; customerobject.email=document.getElementById("email").value; objectarray.push(customerobject); displayList(); }目录中找到// RETRIEVING ALL Queries Query allQueries = firebaseFirestore .collection("yourcollection") .orderBy("timestamp", Query.Direction.DESCENDING) .limit(5); allQueries.addSnapshotListener(new EventListener<QuerySnapshot>() { @Override public void onEvent(QuerySnapshot documentSnapshots, FirebaseFirestoreException e) { for (DocumentChange doc : documentSnapshots.getDocumentChanges()) { if (doc.getType() == DocumentChange.Type.ADDED) { // get all ids String postId = doc.getDocument().getId(); contentProfileDashboard = doc.getDocument().toObject(ContentProfileDashboard.class); contentListDashboard.add(contentProfileDashboard); // fire the event adapterProfileDashboard.notifyDataSetChanged(); } } } });文件夹。确保您指向正确的路径。
