Since you are using main.cpp, you need to do it like this.

gpio_set_pull_mode((gpio_num_t)4, GPIO_PULLUP_ONLY);

esp-idf supports C++, but it's a bit cumbersome.

gpio_set_pull_mode((gpio_num_t)4, GPIO_PULLUP_ONLY);

esp-idf supports C++, but it's a bit cumbersome.

No one should ever use C-style casts in C++. If the function expects an enumeration value as an argument, you should give that function an enumeration value as an argument:

gpio_set_pull_mode(GPIO_NUM_4, GPIO_PULLUP_ONLY);
