# Compiling CCExtractor
You may compile CCExtractor across all major platforms using `CMakeLists.txt` stored under `ccextractor/src/` directory. Autoconf and custom build scripts are also available. See platform specific instructions in the below sections.
Downloads for precompiled binaries and source code can be found [on our website](https://www.ccextractor.org?id=public:general:downloads).
Clone the latest repository from Github
```
git clone https://github.com/CCExtractor/ccextractor.git
```
## Linux
1. Make sure all the dependencies are met.
Debian:
```bash
sudo apt-get install -y libglew-dev libglfw3-dev cmake gcc libcurl4-gnutls-dev tesseract-ocr tesseract-ocr-dev libleptonica-dev clang libclang-dev
```
RHEL:
```bash
yum install -y glew-devel glfw-devel cmake gcc libcurl-devel tesseract-devel leptonica-devel clang
```
Rust 1.54 or above is also required.[Install Rust](https://www.rust-lang.org/tools/install). Check specific compilation methods below, on how to compile without rust
**Note:** On Ubuntu Version 18.04 (Bionic) and (probably) later, install `libtesseract-dev` rather than `tesseract-ocr-dev`, which does not exist anymore.
**Note:** On Ubuntu Version 14.04 (Trusty) and earlier, you should build leptonica and tesseract from source
2. Compiling
### Using the build script
By default build script does not include debugging information hence, you cannot debug the executable produced (i.e. `./ccextractor`) on a debugger. To include debugging information, use the `builddebug` script.
```bash
#Navigate to linux directory and call the build script
cd ccextractor/linux
# compile without debug flags
./build
# compile without rust
./build -without-rust
# compile with debug info
./builddebug
# test your build
./ccextractor
```
### Standard linux compilation through Autoconf scripts
```bash
sudo apt-get install autoconf #Dependency to generate configuration script
cd ccextractor/linux
./autogen.sh
./configure # OR ./configure --without-rust
make
# test your build
./ccextractor
# make build systemwide
sudo make install
```
### Using CMake
```bash
#Create and navigate to directory where you want to store built files
cd ccextractor/
mkdir build
cd build
#Generate makefile using cmake and then compile
cmake ../src/ # options here
make
# test your build
./ccextractor
# make build systemwide
sudo make install
```
`cmake` also accepts the options:
`-DWITH_OCR=ON` to enable OCR
`-DWITHOUT_RUST=ON` to disable rust.
`-DWITH_HARDSUBX=ON` to enable burned-in subtitles
### Compiling with GUI:
To build CCExtractor with a GUI, you will additionally need to install [GLEW](http://glew.sourceforge.net/build.html) and [GLFW](http://www.glfw.org/docs/latest/compile.html)
In order to compile it, you'll need to configure it using autoconf by passing the `-with-gui` option.
```bash
./autogen.sh
./configure --with-gui
make
# make build systemwide
sudo make install
```
Once set up you can run the GUI interface from the terminal `./ccextractorGUI`
## macOS
1. Make sure all the dependencies are met. Decide if you want OCR; if so, you'll need to install tesseract and leptonica.
Dependencies can be installed via Homebrew as:
```bash
brew install pkg-config
brew install autoconf automake libtool
# optional if you want OCR:
brew install tesseract
brew install leptonica
```
If configuring OCR, use pkg-config to verify tesseract and leptonica dependencies, e.g.
```bash
pkg-config --exists --print-errors tesseract
pkg-config --exists --print-errors lept
```
### Compiling
#### Using build.command script:
```bash
cd ccextractor/mac
./build.command # OR ./build.command OCR
# test your build
./ccextractor
```
#### Using CMake
```bash
#Create and navigate to directory where you want to store built files
cd ccextractor/
mkdir build
cd build
#Generate makefile using cmake and then compile
cmake ../src/ # options here
make
# test your build
./ccextractor
```
`cmake` also accepts the options:
`-DWITH_OCR=ON` to enable OCR
`-DWITHOUT_RUST=ON` to disable rust.
`-DWITH_HARDSUBX=ON` to enable burned-in subtitles
#### Standard compilation through Autoconf scripts:
```bash
cd ccextractor/mac
./autogen.sh
./configure # OR .configure --without-rust
make
# test your build
./ccextractor
```
#### Compiling with GUI:
To use CCExtractor with a gui you will additionally need to install GLEW and GLFW. You can do that by installing it via homebrew using:
```bash
brew install glfw
brew install glew
```
In order to compile it, you'll need to configure it using autoconf by passing the `-with-gui` option.
```bash
./autogen.sh
./configure --with-gui #OR .configure --with-gui --without-rust
make
```
Once set up, you can run the GUI interface from the terminal `./ccextractorGUI`
## Windows
Dependencies are clang and rust. To enable OCR, rust i686-pc-windows-msvc target should be installed
Note: Following screenshots and steps are based on Visual Studio 2017, but they should be more or less same for other versions.
1.Open `windows/` directory to locate `ccextractor.vcxproj`, `ccextractorGUI.vcxproj` (blue arrows) and `ccextractor.sln` (red arrow).
![Project Files](img/projectFiles.png)
2.Accept the security prompt (if any), to proceed with compilation.
![A warning you can receive](img/Warning.png)
3.Using Visual Studio (2015 or above), open ccextractor.sln. This will build both CCExtractor and its GUI. To build them separately, open the respective .vcxproj file.
4.In Solution Explorer, you'll see two projects with the VS version and Windows release version in parenthesis. Change them to parameters which are true for you by clicking right mouse button on project and selecting properties.
![Project Section](img/ProjectSection.png)
![Properties, that you have to change](img/Properties.png)
5.Right click and select `build` to compile the project and generate executable file.
![Building button](img/Building.png)
6.Find the executable file in `Debug` or `Release` folder, based on selected configuration.
![Path to Binaries](img/Binaries.png)
Configurations options are: `(Debug|Release)-Full`
Configurations options include dependent libraries which are used for OCR.
### Using CMake
You may also generate `.sln` files for Visual Studio and build using build tools, or open `.sln` files using Visual Studio.
```bash
cmake ../src/ -G "Visual Studio 14 2015"
cmake --build . --config Release --ccextractor
```
### Using MSBuild
Run the following command in `windows/` directory
```bash
msbuild ccextractor.sln /p:Configuration=Release /p:Platform=x64
```
Different configuration options are,
| Configuration | Platform | Rust target required |
| ------------- |:-------------:| -----:|
| Release | x64 | default |
| Debug | x64 | default |
| Release-Full(OCR) | Win32 | i686-pc-windows-msvc |
| Debug-Full(OCR) | Win32 | i686-pc-windows-msvc |
## Building Installation Packages
### Arch Linux
Go to the package_creators folder using `cd` and run the `./arch.sh`
### Redhat Package Manager (rpm) based Linux Distributions
