Hello
I installed eclipse ide 2020 and trying to set dialect flag
My test code

int main() {
  std::cout << __cplusplus << std::endl;
  return 0;
}

If I use terminal command $ g++ -std=c++1z -Wall -o hello 2_w_1_t_1.cpp
index.php/fa/38495/0/

Output is 201703 . It's what i am waiting
But if I try to set -std=c++1z flag in Eclipse IDE Settings this flag don't work.
C/C++ -> Build -> Settings -> GCC Built-in Compiller Settings
${COMMAND} ${FLAGS} -std=c++1z -E -P -v -dD "${INPUTS}"
I have 201402 not 201703

Please tell what I am doing wrong

Set the Allocate Console in the Builtin Compiler Settings provider
index.php/fa/38503/0/

You should be able to see the command being executed
index.php/fa/38504/0/

Understand that this only affects the Indexer.
To create makefiles with -std=c++1z you need to set it in
Project --> C/C+ Build --> Settings --> Tool Settings tab --> <c++ compiler> --> Dialect
It's not a standard setting so you will probably have to use the Other dialect flags edit box
This will then use the dialect in compiles.
