5 min readTo use the <random> library with g++ on a Mac, you simply need to include the header file <random> in your C++ program and compile it with the g++ compiler. You can include the header file at the beginning of your program by adding the line #include <random>.When compiling your program with g++, you will also need to use the -std=c++11 flag to enable C++11 features, as the <random> library is part of the C++11 standard.

4 min readTo install g++ on Fedora, you can use the following steps:Open the terminal on your Fedora system. Update the package repository cache by running the command: sudo dnf update Install the g++ compiler by running the command: sudo dnf install gcc-c++ Verify the installation by checking the g++ version: g++ --version After following these steps, you should have successfully installed g++ on your Fedora system and can start compiling C++ programs.

5 min readWhen linking static libraries with g++, you need to specify the library files you want to link with using the -l flag followed by the name of the library (without the lib prefix and the .a extension). You also need to specify the directory where the library files are located using the -L flag.For example, if you have a static library named libfoo.a located in the /path/to/lib directory, you would link it with the following command:g++ -o myprogram main.
-
4 min readTo build a static library in g++, you first need to compile all the source files that you want to include in the library using the g++ compiler. After compiling the source files, you can use the ar command to create the static library archive file.First, compile all the source files using the g++ compiler: g++ -c file1.cpp file2.cpp file3.cpp Next, create the static library archive file using the ar command: ar rcs libexample.a file1.o file2.o file3.

6 min readTo link with the -lrt library using g++, you can simply add it to the command line when compiling your program. You can do this by including the -lrt flag after specifying your source files and any other necessary libraries. For example, you would compile your program by running the command:g++ myprogram.cpp -o myprogram -lrtThis will tell the g++ compiler to link your program with the real time library (-lrt) when creating the executable file.
-
4 min readTo use a function defined in another file with g++, you need to follow a few steps.First, make sure the function is declared in a header file (.h) that is included in both the file where the function is defined and the file where you want to use the function.Next, compile the file where the function is defined using g++. This will generate an object file (.o).Then, compile the file where you want to use the function, along with the object file generated in the previous step.
-
7 min readTo construct a class defined in another file with g++, you first need to include the header file containing the class definition in your source file using the #include directive. This will allow the compiler to recognize the class and its member functions.Next, you need to compile both the source file and the file containing the class definition using g++. You can do this by running the g++ command in the terminal and providing the names of the source files as arguments.
-
8 min readWhen encountering a memory range overlap issue with the g++ compiler, it typically means that there is a problem with the way memory is being allocated or accessed in your code. This can lead to unpredictable behavior and potentially crash your program. To fix this issue, you need to carefully review your code and ensure that you are properly managing memory allocation and deallocation, as well as accessing memory within the correct boundaries.
-
5 min readTo use a shared library via g++, you need to compile your code with the -l flag followed by the name of the library you want to link. For example, if you have a shared library called libexample.so, you would compile your code with the command g++ -o myprogram myprogram.cpp -lexample. This tells g++ to link your program with the libexample.so shared library.In addition to specifying the library to link, you may also need to specify the path to the directory where the shared library is located.
-
5 min readWhen using g++ to compile C++ code, the -include flag is used to specify a file that should be included in the compilation process before the actual source file is compiled. This can be useful for including a common header file or a file containing preprocessor directives that need to be applied to multiple source files. The contents of the specified file will be inserted at the beginning of the source file during compilation.
-
5 min readTo change the version of g++ in a makefile, you can specify the compiler version by setting the CC variable to the desired g++ version. For example, if you want to use g++ version 7, you would set CC=g++-7 in your makefile. This will instruct the makefile to use g++ version 7 for compiling the code instead of the default version. Make sure that the specified g++ version is installed on your system before updating the makefile.
