[John-Yao]

Type: Debugger
Input information below
Conflict occurs when using unordered_map and cout/cin:
Mingw-w64 runtime failure:
Unknown pseudo relocation protocol version 16777216.

Describe the bug

• OS and Version: windows10
• VS Code Version: 1.32.3
• C/C++ Extension Version:
• Other extensions you installed (and if the issue persists after disabling them):
• A clear and concise description of what the bug is.

To Reproduce
Please include a code sample and launch.json configuration.

src:

include

using namespace std;

include

include

include

int main()
{
std::unordered_map mymap;
mymap["Bakery"]="Barbara"; // new element inserted
mymap["Seafood"]="Lisa"; // new element inserted
mymap["Produce"]="John"; // new element inserted
// printf("hello"); //work!!!
//Error occurs such as that:

Nothing！

Is this a bug with MinGW or do you think our extension has a bug?

[John-Yao]

Thanks for your reply!
I try to compile the same code with CMD(windows):
clang++ test.cpp -o test.exe
And I run the exe. It worked !
So. I think there has a bug in VSCODE or extension.

[sean-mcmanus]

When you run it via VS Code, it goes through the debugger (and doesn't just run the executable(. You may need to add "-g" to your args setting in order for the debugger to work. Or it could be some other debugger issue @WardenGnaw .

I try to run the gdb debugger . And I cat logs such as that(It run normally):

I seem to find the way to solve the problem,and the debugger and runner work:
Modify the settings.json（by remove --target=x86_64-w64-mingw ）
// "code-runner.executorMap": {
// "c": "cd $dir && clang $fileName -o $fileNameWithoutExt.exe -Wall -g -Og -static-libgcc -fcolor-diagnostics --target=x86_64-w64-mingw -std=c11 && $dir$fileNameWithoutExt",
// "cpp": "cd $dir && clang++ $fileName -o $fileNameWithoutExt.exe -Wall -g -Og -static-libgcc -fcolor-diagnostics --target=x86_64-w64-mingw -std=c++1z && $dir$fileNameWithoutExt"
// },
"code-runner.executorMap": {
"c": "cd $dir && clang $fileName -o $fileNameWithoutExt.exe -Wall -g -Og -static-libgcc -fcolor-diagnostics -std=c11 && $dir$fileNameWithoutExt",
"cpp": "cd $dir && clang++ $fileName -o $fileNameWithoutExt.exe -Wall -g -Og -static-libgcc -fcolor-diagnostics -std=c++1z && $dir$fileNameWithoutExt"
},
Modify the task.json（by remove --target=x86_64-w64-mingw ）:
"command": "clang++", // 如果用MinGW，编译C用gcc，编译c++用g++
"args": [
"${file}",
"-o", // 指定输出文件名，不加该参数则默认输出a.exe
"${fileDirname}/${fileBasenameNoExtension}.exe",
"-g", // 生成和调试有关的信息
"-Wall", // 开启额外警告
"-static-libgcc", // 静态链接
"-fcolor-diagnostics",
// "--target=x86_64-w64-mingw", // 默认target为msvc，不加这一条就会找不到头文件
"-std=c++1z" // c++1z即c++17，C语言最新标准为c11，或根据自己的需要进行修改
], // 编译命令参数

Thank you, I solve my problem following your instructions, although I don't why it works.
