False Clang Intellisense Error

[dedvalson]

I am seeing the  following incorrect error marking in Clang Intellisense.
#include
#include
void foo() {
std::stringstream stream;
stream << "Some Text";
stream << std::string("Some Other Text");
}
The << has the squiggly red underline. Floating over the first one displays:
Error [Clang IntelliSense] Error: invalid operands to binary expression ('std::stringstream' (aka 'basic_stringstream') and 'const char *')
Floating over the second one displays:
Error [Clang IntelliSense] Error: invalid operands to binary expression ('std::stringstream' (aka 'basic_stringstream') and 'std::string' (aka 'basic_string'))
The error can be reproduced by taking the standard “Blink” demo project and adding the c++ file above to it.
Is there a workaround for this?

What happens if you wrap it in a __cplusplus guard? Looks like it is treating that source as a c file.

Just tried the __cplusplus guard, it made no difference.

Thanks for the suggestion.

Wow, I left out all the details.

This is an ESP-IDF 5.02 project.

I am using:

ESP32 toolchain 12.2.0/12.1/r1

VisualGDB 5.6R9 (build 4777)

Hi,

Sorry, it doesn’t look like any known issue. Most likely, some file somewhere got corrupt and is interfering with IntelliSense.

Our best advice would be to reset the environment (toolchain, ESP-IDF) and try creating a new project from scratch. If the problem doesn’t reappear on the new project, try comparing the project files between the working and non-working projects to pinpoint the setting that could be causing this.

Hi,

In response to your request, I reloaded my toolchain and it did in fact solve the problem.

Thanks for the help.
