Why cant capture any data?

[gfa99]

#include <string>
#include "easy/profiler.h"
#include "easy/arbitrary_value.h"
#include <iostream>

int main()
{
  EASY_MAIN_THREAD;
  EASY_PROFILER_ENABLE;
  EASY_FUNCTION();
  EASY_BLOCK("main");
  auto sum = 0;
  for(long i=0; i< 100'000'000; i++) {
    EASY_BLOCK("loop");
    sum +=i;
  }
  std::cout << "hello world" << std::endl;
  EASY_END_BLOCK;
  auto blk_cnt = profiler::dumpBlocksToFile("easy_profile2.prof");
  std::cout << "Blocks count: " << blk_cnt << std::endl;
  return 0;
}

cmake_minimum_required(VERSION 3.5)
project(demo)

find_package(easy_profiler REQUIRED)

add_executable(demo ./test.cpp)
target_compile_definitions(demo PUBLIC BUILD_WITH_EASY_PROFILER)
target_link_libraries(demo easy_profiler)

My test demo is shown above, but I always get a block of size 0, at the same time the easy_profiler_gui tips
Cannot read profiled blocks Reason: Wrong memory size == 0 for 0 blocks
Did I do something wrong？
btw: I'm using version 2.1.0

Try remove EASY_MAIN_THREAD, i never use it

May be try connect on runtime via gui, for this add

EASY_PROFILER_ENABLE;
profiler::startListen();

Hello @gfa99,

Thanks for reporting this issue.

You need to close all opened blocks using EASY_END_BLOCK.

In your case, you have opened two blocks with:

EASY_FUNCTION();
EASY_BLOCK("main");

Therefore, you should explicitly close them twice using EASY_END_BLOCK, or alternatively, move the logic inside a function so that the block gets closed automatically in the destructor.

I believe we should handle this within the dumpBlocksToFile function, but we need to carefully consider the synthetic case.
