compilation error

[tkona]

Hi,

I tired you library, but I am getting fatal error:

[danaack]

Hi @tkona,

Thanks for reaching out! What was your method of cloning the library, are you using v2.20 from https://www.arduinolibraries.info?

[tkona]

Hi, Danaack,

no, I dowloaded it from github. Found it on google..

Shell I use the one you provided a link for?

Best regards, Natko

If you will be compiling on Arduino, that will be the simplest option for you. You can accomplish this by either:

• Downloading the .zip file from https://www.arduinolibraries.info/libraries/ion-db

• Or in the Arduino IDE selecting Sketch -> Include Library -> Manage Libraries... -> search for IonDB

Example use sketches can be found in the examples folder or File -> Examples -> IonDB.

If you are not compiling on Arduino, please let me know what error you were getting and I can try and help you further.

Thank you very much for helping. It is compiled for esp32. I will try this tomorrow, and let you know.

Best regards, Natko

Hi, Danaack,

I have change the library, so it compiles now. However, when using it as a Ditctionary<char, int>, I am getting wrong results from the get function.

For example,

Dictionary < char, int > *m_Numbers = new SkipList<char, int>(-1, key_type_char_array, sizeof(char), sizeof(int), 21);

m_Numbers->insert('0', 0); m_Numbers->insert('1', 1); m_Numbers->insert('2', 2); m_Numbers->insert('3', 3); m_Numbers->insert('4', 4); m_Numbers->insert('5', 5); m_Numbers->insert('6', 6); m_Numbers->insert('7', 7); m_Numbers->insert('8', 8); m_Numbers->insert('9', 9); m_Numbers->insert('A', 10); m_Numbers->insert('C', 11); m_Numbers->insert('E', 12); m_Numbers->insert('F', 13); m_Numbers->insert('H', 14); m_Numbers->insert('J', 15); m_Numbers->insert('L', 16); m_Numbers->insert('P', 17); m_Numbers->insert('S', 18); m_Numbers->insert('U', 19); m_Numbers->insert('-', 20);

m_Numbers->get('A') - returns 4, should be 10, m_Numbers->get('C') - returns 10, should be 11, m_Numbers->get('-') - returns 10, should be 20...

Hi Natko,

I'm glad you were able to get it compiling! As for the wrong value being returned, I tried it out on Arduino and I was able to get the correct output with the following sketch:

void
setup(
) {
  Serial.begin(9600);

  Dictionary < char, int > *m_Numbers = new SkipList<char, int>(-1,
  key_type_char_array, sizeof(char), sizeof(int), 21);

  m_Numbers->insert('0', 0);
  m_Numbers->insert('1', 1);
  m_Numbers->insert('2', 2);
  m_Numbers->insert('3', 3);
  m_Numbers->insert('4', 4);
  m_Numbers->insert('5', 5);
  m_Numbers->insert('6', 6);
  m_Numbers->insert('7', 7);
  m_Numbers->insert('8', 8);
  m_Numbers->insert('9', 9);
  m_Numbers->insert('A', 10);
  m_Numbers->insert('C', 11);
  m_Numbers->insert('E', 12);
  m_Numbers->insert('F', 13);
  m_Numbers->insert('H', 14);
  m_Numbers->insert('J', 15);
  m_Numbers->insert('L', 16);
  m_Numbers->insert('P', 17);
  m_Numbers->insert('S', 18);
  m_Numbers->insert('U', 19);
  m_Numbers->insert('-', 20);

  /* Retrieve a value by providing a key */
  int my_value1 = m_Numbers->get('A');

  /* You should check the status on every operation to ensure good data integrity */
  if (err_ok != m_Numbers->last_status.error) {
    printf("Oh no! Something went wrong with my get operation\n");
  }

  printf("A -> %d\n", my_value1);

  my_value1 = m_Numbers->get('C');

  /* You should check the status on every operation to ensure good data integrity */
  if (err_ok != m_Numbers->last_status.error) {
      printf("Oh no! Something went wrong with my get operation\n");
  }

  printf("C -> %d\n", my_value1);

  my_value1 = m_Numbers->get('-');

  /* You should check the status on every operation to ensure good data integrity */
  if (err_ok != m_Numbers->last_status.error) {
      printf("Oh no! Something went wrong with my get operation\n");
  }

  printf("- -> %d\n", my_value1);

  /* Always clean up your dictionaries when you're done with them! */
  delete m_Numbers;
}

void
loop(
) {}

Was your code similar?

Hi Danaack,

Yes, almost the same, only without error checking after the get method. However, the result of the get method is totally different.

I don't have time right now to debug it thoroughly, and I ended writing my own methods, but I will try to help identify the problem when I catch some spare time.

Thank you for your cooperation.

Best regards, Natko
