[Solved] QT Compile Error: nmake: fatal error u1077

One possibility is that the installation path of VS is not added to the environment variable
an error is reported:
nmake 👎 Error: u1077: “D:\program files (x86)\Microsoft Visual Studio 14.0\VC\bin\AMD64\link.Exe”: return code “0x486”

Solution:

Add to the environment variable:

D:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\BIN

reason:
After adding a new file on another computer or another operating system, submitting it to GitHub, and then returning to the current computer to pull the code, the new file is not imported into the VS project

Solution:
Add the newly created file to the current project, “head/source file→ \rightarrow→Add to→ \rightarrow→Existing items”

[Solved] CMake Error: Could not create named generator Visual Studio 16 2019 -A Win64

Preface
CMake Error: Could not create named generator Visual Studio 16 2019 -A Win64
When using vcpkg to compile OsgEarth, the official compilation method is:
cmake -S osgearth -B build -G “Visual Studio 15 2017 Win64” -DCMAKE_BUILD_TYPE=RelWithDebInfo -DWIN32_USE_MP=ON -DCMAKE_INSTALL_PREFIX=[installroot] -DCMAKE_TOOLCHAIN_FILE=[vcpkgroot]\scripts\buildsystems\vcpkg.cmake


Change the commands below:
cmake -S osgearth -B build -G “Visual Studio 15 2017 Win64” -DCMAKE_BUILD_TYPE=RelWithDebInfo -DWIN32_USE_MP=ON -DCMAKE_INSTALL_PREFIX=[installroot] -DCMAKE_TOOLCHAIN_FILE=[vcpkgroot]\scripts\buildsystems\vcpkg.cmake
to:
cmake -S osgearth -B build -G “Visual Studio 16 2019” -DCMAKE_BUILD_TYPE=RelWithDebInfo -DWIN32_USE_MP=ON -DCMAKE_INSTALL_PREFIX=E:\osgEarth\vcpkg\vcpkg\build -DCMAKE_TOOLCHAIN_FILE=E:\osgEarth\vcpkg\vcpkg\scripts\buildsystems\vcpkg.cmake
That is
(1) Remove Win64
(2) Then change installroot to your OsgEarth generation project path, for example, here is: the path to generate OsgEarth.sln project

(3) Set the path of vcpkg.cmake to

Vs + QT reports an error “vs cannot open the source file qchartview”

Vs + QT reports an error “vs cannot open the source file qchartview”

Just started to develop QT program with VS, not familiar with VS, #include & lt; QChartView> always reports an error and cannot open the source program. The solution is as follows:


add the two directories shown in the figure to the included directory. If qtcharts are not found, it indicates that qtcharts was not installed when QT was installed, and the qtcharts component needs to be reinstalled.

Error occurred during Microsoft Visual Studio execution. Msb8020 reported an error

Project scenario:

Version inconsistency and error report during using Visual Studio

Solution:
The reason is that in Debug mode, some libraries are used in conflict, we just ignore the conflicting libraries.

Vs2019 + QT parses the XML file and reports an error at doc.setcontent (& file)

Vs2019 + QT parses the XML file and reports an error at doc.setcontent

Made a very low-level mistake. Record the process.

A QT project was established long ago. Now to add a function of parsing XML files using the qdom class, there is always an error in the sentence doc.setcontent (& amp; file) , and there is no error message. The relevant C + + codes are as follows:

QString error;
int line, column;
if (doc.setContent(&file, &error, &line, &column)) {
    qDebug() << doc.toString(4);
}
else {
    qDebug() << "Error:" << error << "in line " << line << "column" << column;
}
file.close();

When doc.setcontent (& amp; file, & amp; error, & amp; line, & amp; column) , critical error detected c00000374 is displayed

The first reaction is that the XML file is incorrectly written. For example, there is no space in the space, Chinese punctuation is entered, or the two sides of the tag are inconsistent
after repeatedly confirming that the XML file is correct, the stackoverflow search said that the relative path cannot be used, but the absolute path must be used… Another attempt of the absolute path is useless.

Create a new project and run it with the same code without error. Through careful comparison, it is found that in the new project, I added the XML class library

but not in the original project!

So far, add $(qtdir) \ include \ qtxml in the C/C + + include directory, add qt5xmld.lib [debug mode] and qt5xml. Lib [release mode] in the linker, and the operation is successful!

Finally, I found that if the XML file is written incorrectly, the above program can locate the error location. Direct reporting of fatal error/critical error or unresolved external symbols like this__ declspec(dllimport) public: __ Cdecl , the probability is that the Lib file link is wrong rather than the code problem. You need to check whether the environment is configured correctly.

A simple question has been wordy for a long time… Mainly to warn yourself that you must think more and think more about ways to expose the problem when you encounter a problem that has no solution on the Internet!

Error 1 fatal error LNK1220: ‘/PGD‘ requires ‘/LTCG:[PGINSTRUMENT|PGOPTIMIZE]‘ specification

VS2008 compilation of an MFC project pop-up error, looking for a long time, did not find the problem.

  resolvent,

According to the official article:/PGD (specify database for profile guided optimizations) | Microsoft docs

  It says how to solve this problem,

  Setup steps,

1. Open the project property setting (right click on the solution project and select properties),

2. Select link = & gt; Optimization=> Profile Guided Database

3. Select & lt; inherit from parent or project defaults>, Click apply and confirm. Then compile and solve the problem.
