Console Input Output file for GNU C

This is conio.h compatible header file for gcc. Tried and tested on ubuntu linux from 9.10 to 19.04

You don’t need to any special installation for this file. Simply copy the ‘conio.h’ file to your ‘include’ directory. e.g. sudo cp conio.h /usr/include

Hint — installation copied from conio4gcc:

sudo make install copies conio.h to the include directory. sudo make uninstall removes conio.h from the include directory.

It will work without copying the conio.h to /usr/include First compile the example file gcc example.c -o example Run the example ./example

GNU C++ requires namespaces so you must enable them in the header file before using them. Please uncomment line number 54 and 207 in conio.h

README.md

If you see at the top of some C/C++ code, 90% of the time you’ll see the line #include .

We’re including the file into our main program. The header file contains certain library functions that peform input and output operation.

#include is a header file, conio stands for console-input-output and (.h) is basically header file extension.

It contains some functions and methods for formatting the output and getting input in the console.

The error will be shown like below :

cprintf cscanf gotoxy clrscr textcolor textbackground wherex wherey getch getche ungetch kbhit putch putchar cputs clreol insline (not implemented) delline (not implemented) cgets (not implemented) getpass (not implemented) gettext (not implemented) _cprintf _cscanf _cputs _getche _kbhit _putch _ungetch 

Some of it’s functions which are often used :

• kbhit — Determines if a keyboard key was pressed.
• gcgets — Reads a string directly from the console.
• cscanf — Reads formatted values directly from the console.
• putch — Writes a character directly to the console.
• cputs — Writes a string directly to the console.
• cprintf — Formats values and writes them directly to the console.
• clrscr — Clears the screen.
• getch — Get char entry from the console

How To Install Library #include

This is a library conio.h for linux. Just copy file and paste file conio.h on /usr/include/ but don’t forget before you want copy paste on /usr/include/ you must open folder as ADMINISTRATOR first !!

• Open your terminal can as root
• sudo apt-get update
• sudo apt-get upgrade
• sudo apt-get install git
• git clone https://github.com/zoelabbb/conio.h.git or Click to Clone Repos
• cd conio.h

Now you can using library #include .

conio.h: No such file or directory using Linux?

I don’t know what function is causing this error in Linux. I read details about how conio.h is not part of the C standard library. My code:

G++ Conio.H: No Such File or Directory

There’s no direct equivalent for g++. conio.h is specific to some DOS compilers. But you can get what you want using ncurses library, its functions are similar to ones in conio.h .

Here’s a link to a very elaborate tutorial: http://tldp.org/HOWTO/NCURSES-Programming-HOWTO/

Where is the conio.h header file on Linux? Why can’t I find conio.h ?

conio.h is a C header file used with old MS-DOS compilers to create text user interfaces. Compilers that target other operating systems, such as Linux-based, 32-bit Windows and OS/2, provide equivalent functionality through other header files and libraries.

The #include will give you almost all of the functionality provided by conio.h .

«ncurses» needs to be installed in the first place.

If you use the Apt package manager:

sudo apt-get install libncurses5-dev libncursesw5-dev

sudo yum install ncurses-devel ncurses

For getch , take a look at the «NCURSES Programming HOWTO» article.

An error while compiling a C file. fatal error: ‘conio.h’ file not found

• dos.h is, as the name hints, the MS DOS API provided by Borland for their Turbo C and Turbo C++ compilers. It contains everything you need for MS DOS programming. You need to compile with Turbo C on a MS DOS compatible computer for
  that code to run. Some Windows version like Win
  95/98 still had MS DOS emulation.
• conio.h is a console user interface API, supported at some extent by several other MS DOS compilers.
• graphics.h is Borland’s fancy EGA graphics library «Borland Graphics Interface». You need a fancy EGA graphics card to run it. And of course, a MS DOS computer with Borland Turbo C. A monitor that supports 16 colors is recommended.

So first you have to download Turbo C from The Borland Museum — Antique Software: Turbo C version 2.01.

After doing so, you need to contact technical museums and ask around if anyone have preserved an ancient computer that you could borrow. Or alternatively, you could spend weeks trying to get some «DOSBox» emulator working on your Mac. You might have to run the DOS emulator in a Windows emulator, I would assume.

Visual Studio Code python.h: No such file or directory windows gcc

The problem was a combinations of simple mistakes and as a beginner I solved it by some digging in gcc -l -L option flags for library link example and gcc arguments docs.

There are several simple and important points that should be observed:

1. The order of options is really important. If its wrong, compiler wont work. It should be like -I(capital i),-g,-L,-l(lower case L),-o.

2. To embed python in C++ firstly the path to python include files have to be known to compiler by -I option. Then the path to python libraries by a -L option. Then name of the each required python .lib file contained in libs folder of python.

 "-IC:/Users/MPC/AppData/Local/Programs/Python/Python38-32/include",=>(path to python include files) 
"-g",=>(debug option specified by ide) 
"$", 
"-LC:/Users/MPC/AppData/Local/Programs/Python/Python38-32/libs",=>(path to python libraries) 
"-lpython38",=>(python lib contained in python libs) 
"-lpython3",=>(python lib contained in python libs) 
"-l_tkinter",=>(python lib contained in python libs) 
"-o",=>(output argument specified by ide) 
"$\\$.exe"

I hope that with this answer, the beginners like me, get to the conclusion faster.
There is also a good youtube tutorial of Embedding python in C++ with CMake and Pybind11 and VS Code

Errors when compiling C program with pointers

1. conio.h is not a standard C header. It might be unavailable on your system. Nevertheless, it’s not needed for printf(). That’s why stdio.h is here. Remove it, and also remove clrscr(). It won’t work without the conio libraries. By doing this, you’ll able to compile your file, since the other messages are «just» warnings, not errors.
2. Change your main() function’s return type to int and return 0. That’s what the C standard specifies. You want this.
3. Use the %d format specifier in place of %u . As the compiler message directly points out, %u is for unsigned integers, and int is explicitly signed. For integers >= 2 ^ 31, you’ll experience strange behavior problems.
4. You’re using a wrong specifier one more time. Use %p for addresses/pointers, not %u/%d/whatever.
5. Don’t explicitly believe/copy-paste from tutorials. Tutorials are not for copy-pasting, they’re to be thought of and learnt from.

Fatal error: iostream: No such file or directory in compiling C program using GCC

Neither nor are standard C header files. Your code is meant to be C++, where is a valid header. Use a C++ compiler such as clang++ or g++ (and a .cpp file extension) for C++ code.

Alternatively, this program uses mostly constructs that are available in C anyway. It’s easy enough to convert the entire program to compile using a C compiler. Simply remove #include and using namespace std; , and replace cout
