Cannot properly set Include and Defines with third-party compilers #4269

Describe the bug

OS and Version: Windows 10 (Windows_NT x64 10.0.17763)
VS Code Version: 1.38.1
C/C++ Extension Version: 0.25.1
It does not seem possible to use compileCommands plus other global includes/defines taken from includePath and defines properties respectively.

I'm using a third-party compiler (ARM) which has its own includes and defines, but I also need to use project-related include/defines taken from compile_commands.json (generated via CMake).
I'm trying to set compiler-specific includes/defines manually, and then use compileCommands property for project-specific includes/defines.

This is a minimal version of my c_cpp_properties.json:

{
    "configurations": [
        {
            "name": "ARM",
            "compilerPath": "",
            "cStandard": "c99",
            "cppStandard": "c++03",
            "intelliSenseMode": "gcc-x86",
            "compileCommands": "${workspaceFolder:Project}/.vscode/compile_commands.json",
            "defines": [
                "__ARM__"
            ],
            "includePath": [
                "\"C:\\Program Files (x86)\\ARM_Compiler_5.06u4\\include\""
            ]
        }
    ],
    "version": 4
}

Also I would like to set something like "intelliSenseMode": null, because neither MSVC, GCC nor CLang are correct choices for my case. Why does IntelliSense need this info?

This is the full Log Diagnostics output (except sensitive paths):

This is a screenshot to show the problems encountered:

I see 3 main problems:

Include paths: the include path list (inside Log Diagnostics) does not contain the includePath specified in c_cpp_properties.json, but only the paths found in compile_commands.json; Since my includePath is not present, the compiler headers are not recognized (e.g. string.h is not found as you can see from the screen);
Defines: viceversa, the defines list contains only the ones specified manually into c_cpp_properties.json but does not contain the ones from compile_commands.json; moreover, even if the macro is present in the list (e.g. __ARM__), the editor does not recognizes it and the wrong preprocessor branch is greyed out!
IntelliSense Mode: it seems that there is no suitable intelliSenseMode for my use case; I put gcc-x86, but CPPTools seems to ignore it anyway (you can see gcc-x64 in the Log Diagnostics); I would also like to avoid the section "Other Flags" which seems to contain gcc-related stuff.

Expected behavior
In the Log Diagnostics I expect to see the union of includes/defines from both c_cpp_properties.json and compile_commands.json, and I expect them to work in the editor.

The text was updated successfully, but these errors were encountered:

hi,
try to change this:
"includePath": [
""C:\Program Files (x86)\ARM_Compiler_5.06u4\include""
]
to this:
"includePath": [
""C:\Program Files (x86)\ARM_Compiler_5.06u4\include\**""
]

sean-mcmanus · 2019-09-18T19:45:52Z

@CfirTsabari Using "**" with system includes is not recommended because the ordering may not be correct. If subfolders are required, it's better to just list them in the correct order.

@gentooise Our compiler only supports emulation of cl.exe, gcc, and clang, so it needs to be set to one of these modes.

It looks like our C/C++: Log Diagnostics command has a bug in the compile_commands.json scenario where it is showing the c_cpp_properties.json instead of the defines obtained from the compile_commands.json -- I could file a new bug for that: #4270 .

Our compile_commands.json and configurationProvider were designed to ignore the includePath and defines in c_cpp_properties.json, unless a source file is encountered that doesn't have configuration info. One workaround is to set your compilerPath to a .bat (Windows) or .sh (Linux/Mac) script that outputs the system includes and defines you want, such as

@ECHO OFF
echo #include "..." search starts here:
echo #include ^<...^> search starts here:
echo End of search list.
echo #define MYDEF1=1

Let us know if that workaround doesn't work for you. We have a fix pending for the lack of support for "${workspaceFolder}" in the compilerPath and compilerArgs: #3440 .

sean-mcmanus · 2019-09-18T19:54:12Z

Actually, it looks like the arm compiler should be "the same" as gcc. Can you check what error occurs when you specific that compiler as the compilerPath? Is our mechanism for querying the compiler for system includes and defines failing? enabling debug logging might give better failure info.

sean-mcmanus · 2019-09-18T19:56:32Z

Is the ARM compiler you're using publicly available for us to try out?

sean-mcmanus · 2019-09-18T20:26:39Z

Also, we don't have the proper flags/settings enabled to give 100% correct results for ARM -- specifically we need to add intelliSenseMode's for gcc-arm, gcc-arm64, clang-arm, clang-arm64, windows-arm, windows-arm64 support. I should file a new issue to track that: #4271

I understand. I will try ASAP and let you know, but I do not understand some details of the expected output format (search starts here:, ^<...^>?). Could you directly give me an output example for the script?

Actually, it looks like the arm compiler should be "the same" as gcc. Can you check what error occurs when you specific that compiler as the compilerPath? Is our mechanism for querying the compiler for system includes and defines failing? enabling debug logging might give better failure info.

Unfortunately not, ARM Compiler is not the same as GCC, it is a commercial compiler that has its own includes, macros, and command line arguments. I can put it in compilerPath anyway and let you know ASAP, but I already know how this compiler works:

it has no specific arg to get built-in include paths (they are fixed and documented here);
it only has an argument to get builtin macros (--list_macros), but the output format does not seem equivalent to the gcc one.

My point is that it could be useful to have a generic way to handle compilers that are not specifically supported: your hint about a script file could be one way to do it. Another way could be to have the possibility to (manually) put other includes/defines in addition to the ones found in compile_commands.json.

Is the ARM compiler you're using publicly available for us to try out?

Unfortunately not, it can be only used by purchasing a license.

Also, we don't have the proper flags/settings enabled to give 100% correct results for ARM -- specifically we need to add intelliSenseMode's for gcc-arm, gcc-arm64, clang-arm, clang-arm64, windows-arm, windows-arm64 support. I should file a new issue to track that: #4271

Please note that the compiler is not gcc-arm or clang-arm. The correct names are armcc and armclang, and they have nothing to do with gcc. I already know it because I recently encountered similar issues for an eclipse plugin (here).

Finally, I have another question: which is the purpose of the configurationProvider? What does it add with respect to compileCommands option? Because in my case I'm using CMake with CMake Tools VSCode extension, and this extension is made to be a configuration provider. But to me this seems redundant, because the information provided by the CMake Tools is always taken from compile_commands.json, which is the unique source of information that comes out from CMake. So, which is the difference between using compileCommands only, configurationProvider only or both of them?

Yes it is failing because it seems to switch to MinGW GCC. This is the output of Log Diagnostics:

As you can see, it assumes that the compiler is MinGW GCC, and takes in all its include paths.

Anyway, I enabled debug logging but I don't see any output difference, please tell me where to find debug logs (if any).

I tried also this, and I got the same result as above (same Log Diagnostics), except for the line:
"compilerPath": "${workspaceRoot}/.vscode/compile.bat",

where compile.bat contains the following:

@ECHO OFF
echo #include "..." search starts here:
echo #include ^<...^> search starts here:
echo "C:\\Program Files (x86)\\ARM_Compiler_5.06u4\\include"
echo End of search list.
echo #define __ARM__=1

sean-mcmanus · 2019-09-20T00:50:54Z

Yeah, the defines being incorrect is a bug in the logging output.

The ^< is just to escape the < so the output should not contain the ^ but otherwise should appear the same -- you may need to escape other characters though too.

If you're using CMake and the CMake Tools extension, you would probably get better results if you set the configurationProvider setting and not the compileCommands setting. Is the CMake Tools extension able to get the correct system includes/defines?

The .bat file probably doesn't work because haven't shipped the fix for ${workspaceFolder} not working in compilerPath: #3440 . However, even after using the full path, I'm getting "Compiler include path not found"...so we need to investigate why that isn't working -- it might only work with Linux-style paths currently.

Got it, thanks.

I'm probably not using the CMake Tools extension correctly, because I get this when opening cpp files:

How does CMT get info from compile_commands.json? It reads the file directly from the current build directory? Or I have to copy it inside .vscode folder? (Consider I have different cmake-variants with different build directories).
Please tell me if this is the right place or I should open an issue for vscode-cmake-tools instead.

I used ${workspaceRoot} in fact, do you think is not working anyway?

UPDATE: I'm going on with the batch script strategy and I noticed that also parenthesis need to be escaped with ^. Right now I have the following situation (which is partially working).

        }
    ],
    "version": 4
}

compile.bat:

I think this is really close to be solved, but I still see the following issues:

The include path is correctly visible in the log at the end of Includes section, but VSCode is still unsure about where to find headers (the right one is only the third choice highlighted in red):

Why am I still seeing MinGW and other includes? This is a problem because later in the same cpp file I get undefined symbols because of wrong includes:

In this case, ARM compiler include is not considered at all, but I can confirm that the file string.h exists in C:\Program Files (x86)\ARM_Compiler_5.06u4\include and it contains a valid definition of snprintf (my code builds correctly).
Defines are not shown inside Log Diagnostics instead, but they are working correctly inside the editor: I think this is always due to C/C++: Log Diagnostics shows incorrect defines when compile_commands.json is used #4270
The IntelliSense Mode still seems to "randomly" switch to different modes (clang-x64 in this case), but I don't know which are the effects of this.

gentooise · 2019-09-20T14:24:27Z

UPDATE2: I made another step forward on issue 1 above:

I added #define __declspec(x)= to the compile.bat. This missing define was causing IntelliSense to get errors while parsing string.h ARM compiler header;
I tried a Reset IntelliSense Database (suggested here), not sure if this helped.

In general I understood that, as a rule of thumb, any non-standard compiler built-in directive should be defined manually (as __declspec() above) in order for IntelliSense to be able to parse compiler-specific headers without throwing errors.

Right now I think my only remaining issues are the following:

Since my compiler include directory has subdirectories that I need to exclude, I need a way to do it from compile.bat. I tried with:
echo C:\Program Files ^(x86^)\ARM_Compiler_5.06u4\include\* or
echo C:\Program Files ^(x86^)\ARM_Compiler_5.06u4\include\^*
but it doesn't work (all include directory is lost);
I need a way to get rid of the x64 IntelliSense Mode, that it seems to cause issues like this:

Here IntelliSense is expecting the wrong size of pointers (I think is due to clang-x64 mode). In this case, since I'm cross-compiling for arm32, I expect the error to be thrown on the first line, not on the second.

sean-mcmanus · 2019-09-20T21:13:56Z

The CMake Tools extension doesn't read compile_commands.json -- it reads the CMakeLists.txt (and/or the CMake cache files) directly.

Go to Def on #include doesn't use the IntelliSense include path and just queries the browse database (we have a bug tracking that).

You could try adding the folders to files.exclude (make sure it doesn't end with a "/", since we haven't shipped the fix for that case yet). We don't handle "*" (non-recursive paths) in the results from the compiler currently -- i.e. it's a bug: #4296 .

Ideally, we would add arm modes (#4271), but to get gcc-x86 to be used, you should set defines __GNUC__=8, __GNUC_MINOR__=0, __GNUC_PATCHLEVEL__=0, because without that it is falling back to a hardcoded default of clang-x64 version 5.0. We could probably also fix it to not use that fallback.

files.exclude seems enough as a workaround for now, thank you.

I added these lines to the compile.bat:

echo #define __GNUC__=8
echo #define __GNUC_MINOR__=0
echo #define __GNUC_PATCHLEVEL__=0

but cpptools now falls back to gcc-x64.

sean-mcmanus · 2019-09-28T02:34:20Z

@gentooise Ah, yeah, thanks for reporting that -- I see in the code where it's setting it to gcc-x64. I filed bug #4353 . I think we'll be able to fix that for our next release (update: it should be fixed in our next Insiders release, today or tomorrow).

sean-mcmanus · 2019-10-02T03:04:39Z

I'm coming late to the discussion. We should write up some documentation about how to work with unsupported compilers.

I think a better approach is to use a combination of the C_Cpp.default.systemIncludePath and C_Cpp.default.defines settings, but we should validate this will provide the expected results before writing up the documentation.

Thanks for the hint. I tried your approach, but it is partially working for me. It is ok for C_Cpp.default.systemIncludePath, but not for C_Cpp.default.defines.

In particular, I'm using C_Cpp.default.systemIncludePath and C_Cpp.default.defines in place of compile.bat, and I also set "C_Cpp.default.compilerPath": "" to avoid further compiler queries.

However, according to this article, C_Cpp.default.defines is ignored when compileCommands is set (case 1), and I verified that is happening in my case. I think it could be useful to have a corresponding C_Cpp.default.systemDefines.

Here diagnostic logs (which shows my system defines anyway, even if they are not used by IntelliSense):
