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
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
