There are several alternatives for compiling C on Linux. Let's look at 2 of them − GCC. Almost all Linux distros come with GCC installed. Check whether GCC is installed on your system by entering the following command from the command line −. Virtual Package: libcurl-dev. This is a virtual package.

Download graphics.h to the include/ subdirectory of the Dev-C directories. Download libbgi.a to the lib/ In order to use the WinBGIm subdirectory of the Dev-C directories. Whenever you #include in a program, you must instruct the linker to link in certain libraries.

- The C Standard Library provides several generic containers, functions to utilize and manipulate these containers, function objects, generic strings and streams (including interactive and file I/O), support for some language features, and functions for everyday tasks such as finding the square root of a number.

The C library function int atoi(const char *str) converts the string argument str to an integer (type int).

C Libraries In general, libraries are created from many library source files, and are either built as archive files (libmine.a) that are statically linked into executables that use them, or as shared object files (libmine.so) that are dynamically linked into executables that use them.
Following is the declaration for atoi() function.
str − This is the string representation of an integral number.

To install and run Flutter,your development environment must meet these minimum requirements:
- Operating Systems: Linux (64-bit)
- Disk Space: 600 MB (does not include disk space for IDE/tools).
- Tools: Flutter depends on these command-line tools being availablein your environment.
- Shared libraries: Flutter

Get the Flutter SDK
On Linux, you have two ways you can install Flutter.
Install Flutter using snapd
The easiest way to install Flutter on Linux is byusing snapd. For more information,see Installing snapd.
Once you have snapd, you caninstall Flutter using the Snap Store,or at the command line:
Note: Once the snap is installed, you can use the following command to display your Flutter SDK path:
Install Flutter manually
If you don’t have
snapd, or can’t use it, you caninstall Flutter using the following steps.
Download the following installation bundle to get the lateststable release of the Flutter SDK:
For other release channels, and older builds,see the SDK releases page.
Extract the file in the desired location, for example:
If you don’t want to install a fixed version of the installation bundle, you can skip steps 1 and 2. Instead, get the source code from the Flutter repoon GitHub with the following command:
You can also change branches or tags as needed.For example, to get just the stable version:
fluttertool to your path:
This command sets your
PATHvariable for thecurrent terminal window only.To permanently add Flutter to your path, seeUpdate your path.
Optionally, pre-download development binaries:
fluttertool downloads platform-specific development binaries asneeded. For scenarios where pre-downloading these artifacts is preferable(for example, in hermetic build environments,or with intermittent network availability), iOSand Android binaries can be downloaded ahead of time by running:
For additional download options, see
flutter help precache.
You are now ready to run Flutter commands!
Note: To update an existing version of Flutter, see Upgrading Flutter.
Run flutter doctor
Run the following command to see if there are any dependencies you need toinstall to complete the setup (for verbose output, add the
This command checks your environment and displays a report to the terminalwindow. The Dart SDK is bundled with Flutter; it is not necessary to installDart separately. Check the output carefully for other software you mightneed to install or further tasks to perform (shown in bold text).
The following sections describe how to perform these tasks and finish the setupprocess.
Once you have installed any missing dependencies, run the
flutter doctorcommand again to verify that you’ve set everything up correctly.

flutter tool uses Google Analytics to anonymously report feature usage statistics and basic crash reports. This data is used to help improve Flutter tools over time.
Flutter tool analytics are not sent on the very first run. To disable reporting, type
flutter config --no-analytics. To display the current setting, type
flutter config. If you opt out of analytics, an opt-out event is sent, and then no further information is sent by the Flutter tool.
Moreover, Flutter includes the Dart SDK, which may send usage metrics and crash reports to Google.
Update your path
You can update your PATH variable for the current session atthe command line, as shown in Get the Flutter SDK.You’ll probably want to update this variable permanently,so you can run
flutter commands in any terminal session.
The steps for modifying this variable permanently forall terminal sessions are machine-specific.Typically you add a line to a file that is executedwhenever you open a new window. For example:
- Determine the directory where you placed the Flutter SDK.You need this in Step 3.
- Open (or create) the
rcfile for your shell.For example, Linux uses the Bash shell by default,so edit
$HOME/.bashrc.If you are using a different shell, the file pathand filename will be different on your machine.
Add the following line and change
[PATH_TO_FLUTTER_GIT_DIRECTORY]to bethe path where you cloned Flutter’s git repo:
source $HOME/.<rc file>to refresh the current window,or open a new terminal window toautomatically source the file.
Verify that the
flutter/bindirectoryis now in your PATH by running:
Verify that the
fluttercommand is available by running:
Note: As of Flutter’s 1.19.0 dev release, the Flutter SDK contains the
dart command alongside the
flutter command so that you can more easily run Dart command-line programs. Downloading the Flutter SDK also downloads the compatible version of Dart, but if you’ve downloaded the Dart SDK separately, make sure that the Flutter version of
dart is first in your path, as the two versions might not be compatible. The following command (on macOS, linux, and chrome OS), tells you whether the
dart commands originate from the same
bin directory and are therefore compatible. (Some versions of Windows support a similar
As shown above, the two commands don’t come from the same
bin directory. Update your path to use commands from
/path-to-flutter-sdk/bin before commands from
/usr/local/bin (in this case). After updating your shell for the change to take effect, running the

dart commands now come from the same directory.
To learn more about the
dart command, run
dart -h from the command line, or see the dart tool page.

Note: Flutter relies on a full installation of Android Studio to supply its Android platform dependencies. However, you can write your Flutter apps in a number of editors; a later step discusses that.
Install Android Studio
- Download and install Android Studio.
- Start Android Studio, and go through the ‘Android Studio Setup Wizard’.This installs the latest Android SDK, Android SDK Command-line Tools,and Android SDK Build-Tools, which are required by Flutterwhen developing for Android.
Set up your Android device
To prepare to run and test your Flutter app on an Android device,you need an Android device running Android 4.1 (API level 16) or higher.
- Enable Developer options and USB debugging on your device.Detailed instructions are available in theAndroid documentation.
- Windows-only: Install the Google USBDriver.
- Using a USB cable, plug your phone into your computer. If prompted on yourdevice, authorize your computer to access your device.
- In the terminal, run the
flutter devicescommand to verify thatFlutter recognizes your connected Android device. By default,Flutter uses the version of the Android SDK where your
adbtool is based. If you want Flutter to use a different installationof the Android SDK, you must set the
ANDROID_SDK_ROOTenvironmentvariable to that installation directory.

- EnableVM accelerationon your machine.
- Launch Android Studio, click the AVD Managericon, and select Create Virtual Device…
- In older versions of Android Studio, you should insteadlaunch Android Studio > Tools > Android > AVD Manager and selectCreate Virtual Device…. (The Android submenu is only presentwhen inside an Android project.)
- If you do not have a project open, you can choose Configure > AVD Manager and select Create Virtual Device…
- Choose a device definition and select Next.
- Select one or more system images for the Android versions you wantto emulate, and select Next.An x86 or x86_64 image is recommended.
- Under Emulated Performance, select Hardware - GLES 2.0 to enablehardwareacceleration.
Verify the AVD configuration is correct, and select Finish.
