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: [Select all] [Expand/Collapse]

1. {
2.     "configurations": [
3.         {
4.             "name": "ESP",
5.             "cStandard": "c11",
6.             "cppStandard": "c++17",
7.             "includePath": [
8.                 "${workspaceFolder}/**",
9.                 "${config:idf.espIdfPath}/components/**"
10.             ],
11.             "browse": {
12.                 "path": [
13.                     "${config:idf.espIdfPath}/components",
14.                     "${config:idf.espIdfPathWin}/components",
15.                     "${workspaceFolder}"
16.                 ],
17.                 "limitSymbolsToIncludedHeaders": false
18.             }
19.         }
20.     ],
21.     "version": 4
22. }

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.
