freertos

[gmereness]

Cannot find a file included in the freertos library - reent.h.
I get a compiler warning and sometimes cannot build/flash the ESP32 part.
Using VSCode to build a project on Ubuntu 18.0.4.
Very annoying - could anyone help out.

I'm having the exact same problem. Any progress on this?

Just found a suggested solution in this forum: viewtopic.php?f=40&t=17818&p=66817&hilit=reent#p66817

But it does not work for me.

What's your c_cpp_properties.json look like?

[slompf]

It looks like this:

Code: Untitled.js Select all

{

    "configurations": [

        {

            "name": "ESP",

            "cStandard": "c11",

            "cppStandard": "c++17",

            "includePath": [

                "${workspaceFolder}/**",

                "${config:idf.espIdfPath}/components/**"

            ],

            "browse": {

                "path": [

                    "${config:idf.espIdfPath}/components",

                    "${config:idf.espIdfPathWin}/components",

                    "${workspaceFolder}"

                ],

                "limitSymbolsToIncludedHeaders": false

            }

        }

    ],

    "version": 4

}

But the sys/reent.h cannot be found in any of the (sub)directories. In fact I did not find it on my system. I'm using esp-idf 4.2. I guess the include was added to FreeRTOS.h in a recent release.

Try add the following (at same depth as "name"):

Code: Select all

"compilerPath": "${config:idf.toolsPath}/tools/xtensa-esp32-elf/esp-2020r3-8.4.0/xtensa-esp32-elf/bin/xtensa-esp32-elf-gcc",
"compileCommands": "${workspaceFolder}/build/compile_commands.json"

Check compilerPath is correct, you may have a different version.

That helped. Thank you very much.
