error compiling for board arduino mega or mega 2560

Most Arduino boards consist of an Atmel-8-bit AVR microcontroller (ATmega8, ATmega168, ATmega328, ATmega1280, ATmega2560), each microcontroller consists of varying amounts of flash memory, pins and functions. The boards use single- or double-row female pins/headers that facilitate connections and incorporation into other circuits.[26] The board has 14 digital pins.
The board has 14 digital pins, 6 analog pins programmable with the Arduino IDE (Integrated Development Environment) via USB cable. It can be powered by the USB cable or by an external 9-volt battery, although it accepts voltages between 7 and 20 volts. It is the flagship of Arduino as it is the most popular board, the one that everyone uses to get started and the simplest to use. It is the starting point for many electronics programming enthusiasts.
The board with the most powerful microcontroller in the Arduino family. With 54 digital pins that function as input and output; 16 analog inputs, a 16 MHz oscillator crystal, a USB connection, a reset button and an input for board power. Arduino MEGA is the board that is used when Arduino UNO falls short of a project’s needs. It has been widely used as a control and computation center in 3D printers….

error compiling for the arduino one card

Is it possible to upload the code and also the errors that I get so that the most knowledgeable people could solve it, for me it would be very useful because I could use that code for other future and thus be able to catch up little by little.
Is it possible to upload the code and also the errors that it gives me so that the most knowledgeable people could solve it, for me it would be of great utility since I could use that code for other futures and in that way to be able to put myself little by little up to date.
For all the previous thing it is of my gratefulness to those but advanced that they did a code to me with those libraries that sure you will know. If I had to provide more data, please ask for it. Let you know that I saw many videos about matrices but I can’t get the code.

Arduino is an open source electronics creation platform, which is based on free hardware and software, flexible and easy to use for creators and developers. This platform allows the creation of different types of single-board microcomputers that can be put to different types of use by the maker community.
Free software is software whose code is accessible by anyone so that anyone can use and modify it. Arduino offers the Arduino IDE (Integrated Development Environment) platform, which is a programming environment with which anyone can create applications for Arduino boards, so that they can be given all kinds of utilities.
The result was Arduino, a board with all the necessary elements to connect peripherals to the inputs and outputs of a microcontroller, and that can be programmed in Windows, macOS and GNU/Linux. A project that promotes the ‘learning by doing’ philosophy, which means that the best way to learn is by tinkering.

exit status 1 error compiling for board arduino/genuino uno solution

I also understand that if it were a library problem, running the «verification» would give me an error in this specific aspect, but not only does it not give a specific error, but it only indicates «Compiling error», which leaves me absolutely unable to find any solution.
I have tried with other sketches that I am sure that they work and the result is correct, they work and it checks them correctly, so I deduce that it is either an error in the sketch, or in the holy library.
It will be more productive if you put the code of your sketch, so we can check it better, because as you say, it does not make sense that parenthesis without previous opening. The 13:19 refers to the line and column in which the error jumps, which does not have to be the place where the error is made.
