In Qt you can add this line to your .pro file to force the compiler to look there for header files. Change it to the folder where your header files are stored. INCLUDEPATH += <your path> 1 solved I am really confused with this kind of compilation error( C ffmpeg Qt)
You have source files card.c, deck.c, and main.c. It is reasonable to suppose that card.c and deck.c each define functions, at least one of which is called by something in main.c, else there would be no need for your header.h. Presumably, the functions named in your link errors are among those. The command gcc main.c … Read more
Your issue is that you are confusing the compiler: spi_start(); initialize(); Are function calls and not function declarations. Please include the return types: void spi_start(); void initialise(); 2 solved Compilation error: expected constructor, destructor, or type conversion before ‘;’ token [closed]
In C and C++ as opposed to C# and Java, variables do not need to be allocated in dynamic memory, which includes strings and character arrays. If you need or want to return pointers from a function, they must point to some variable that won’t disappear after execution leaves the function. The two popular techniques … Read more
Do the following steps: Open your terminal (or) command-line window. Type the following command and then press ENTER sudo apt-get update It will ask for the password. Type your sudo user password and press ENTER Then type the following command and then press ENTER again. sudo apt-get install g++ This will install the g++ compiler … Read more
It’s optimization on level 3, basically a shortcut for several other options related to speed optimization etc. (see link below). I can’t find any documentation on it. … it is one of the best known options: https://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html http://docs.nvidia.com/cuda/cuda-compiler-driver-nvcc/#options-for-altering-compiler-linker-behavior solved What is option -O3 for g++ and nvcc?
use “objdump -D lib_file” the left column will be the ‘binary object code’ and right column – disassembled one. solved How to find object code of c++ file
y = 0; should be int y = 0; because y has not yet be declared at this point and you are defining a variable. 3 solved ‘y’ was not declared in this scope,
This is no specialization, this is instanciation. Templates are managed in two passes. The first is almost syntactic; the compiler just verifies if the code looks like something correct. Then when you use the template (instanciate it) with the given or deduced types, it tries to generate the code (if not already done), so when … Read more
If you check CompilerResults compres it shows that there’s an exception and the compilation was not successful and hence it’s not writing out Assembly.exe and there is a System.IO.FileNotFound exception from Process.Start() Try this public void compile() { CSharpCodeProvider myCodeProvider = new CSharpCodeProvider(); ICodeCompiler myCodeCompiler = myCodeProvider.CreateCompiler(); string myAssemblyName = @”Assembly.exe”; CompilerParameters myCompilerParameters = new … Read more
printf is unusual in that it has no single function signature. In other words, there’s no mechanism to automatically take the actual arguments you pass and convert them into the type that’s expected. Whatever you try to pass, gets passed. If the type you pass does not match the type expected by the corresponding format … Read more
You can compile the program with Visual Studio 2019 (Community Edition will be good) The published github is not friendly…you have to create the project from scratch, follow those steps Create a new WPF project (WPF App (.NET Framework)) Copy all files in the project folder (overwrite MainWindow.xaml and MainWindow.xaml.cs) Add all .cs file to … Read more
Once a binary is created from C++ source files, the original source files are not needed in order to run the program. You can distribute only the compiled program. solved How to compile C++ codes in Linux with source files hidden? [closed]
First profile. Second, turn up optimizations levels on you compiler. Thirdly, replace your for loop with multiplication / algebra. For example, the linea+=N is the fundamental basis for multiplication (repetitive addition), and the loop can be replaced by:a += j * N; N -= j; Replacing the loop will speed up your program (if your … Read more
It seems that the code is buggy, so new compilers refuse to compile it. Edit the code and use a const_cast<char*> (variablename) to remove the constness of the variable. 1 solved sourcecode compilation in linux
