Using Clang Diagnostics
I just started using this extension and it has been working wonderfully for auto-completion. However, I am not able to get it to work for any kind of clang diagnostics. All the diagnostic settings are at their default values: // Enable diagnostic "clang.diagnostic.enable": true,
// The delay after which diagnostic starts (in millisecond) "clang.diagnostic.delay": 500,
// Tolerable size of the clang output for diagnostic "clang.diagnostic.maxBuffer": 262144,
I've also updated the clang.cflags setting to the following: "clang.cflags": ["-std=c99", "-Wall"]
Is there anything else I need to do in order to get diagnostics working? Thanks!
Probably you need to determine include paths and definitions for the project. You need to create "settings.json" file like this "YOUR_PROJECT_ROOT/.vscode/settings.json".
{
"clang.cflags":
[
"-DSTM32F40_41xxx",
"-DHSE_VALUE=8000000",
"-DARM_MATH_CM4",
"-I${env.ARM_NONE_EABI_PATH}/lib/gcc/arm-none-eabi/6.3.1/include",
"-I${env.ARM_NONE_EABI_PATH}/arm-none-eabi/include",
"-I${workspaceRoot}/src",
"-std=gnu99",
"-Wall",
"-fsyntax-only",
"-Wunused-macros",
//"-Weverything",
"-Wno-parentheses"
]
}
Hi, I have added the include paths in the global user settings, but still I am not seeing any diagnostic output. I also tried adding these settings to the workspace settings file (the one you mentioned) without any change. Here are my user settings:
"clang.cxxflags": [
"-std=c++11",
"-Wall",
"-I${workspaceRoot}",
"-I/usr/include/c++/4.2.1",
"-I/usr/local/Cellar/gcc/6.3.0_1/include/c++/6.3.0/"
],
Can you show me what the diagnostic output looks like? Is there a particular way to trigger it or is it triggered automatically?
Are you using the Microsoft "C/C++" extension? I can get an output like the one you showed if I enabled the Microsoft "C/C++" extension. However, if I disable it and try just using the Clang extension, I don't see any output in the Problems tab whatsoever, even when there are known errors (ie, missing semi-colon).

Hello guys,
I'm using VSCode 1.27.2.
Clang diagnostic not working with arm-none-eabi-gcc, but the auto-completion works normally.
Here's the "setting.json"
{
"files.trimTrailingWhitespace": true, // 保存时，删除每一行末尾的空格
"editor.minimap.enabled": false, // 我个人不用minimap，就是右边那个东西
"editor.dragAndDrop": false, // 选中文字后，可以拖动它们调整位置。我是不需要
"editor.mouseWheelZoom": true,
// "files.defaultLanguage": "c", // ctrl+N新建文件后默认的语言
"editor.formatOnType": true, // 输入时就进行格式化，默认触发字符较少，分号可以触发
"editor.snippetSuggestions": "top", // snippets代码优先显示补全
// "code-runner.runInTerminal": true, // 设置成false会在“输出”中输出，无法输入
// "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++17 && $dir$fileNameWithoutExt"
// }, // 设置code runner的命令行
// "code-runner.saveFileBeforeRun": true, // run code前保存
// "code-runner.preserveFocus": true, // 若为false，run code后光标会聚焦到终端上。如果需要频繁输入数据可设为false
// "code-runner.clearPreviousOutput": false, // 每次run code前清空属于code runner的终端消息

"C_Cpp.intelliSenseEngine": "Default", // 可以为Default或Tag Parser，后者较老，功能较简单。具体差别参考cpptools扩展文档
"C_Cpp.errorSquiggles": "Disabled", // 因为有clang的lint，所以关掉

diagnotic not working in the underlying pic
Here's the VSC extensions installed
How can I get it work?
thanks.
Are you using the Microsoft "C/C++" extension? I can get an output like the one you showed if I enabled the Microsoft "C/C++" extension. However, if I disable it and try just using the Clang extension, I don't see any output in the Problems tab whatsoever, even when there are known errors (ie, missing semi-colon).
I'm experiencing the same problem. Have you ever solved this?
