RawTherapee is a powerful, cross-platform raw photo processing program, released under the GNU General Public License Version 3. It is written in C++ using a GTK+ front-end and a patched version of dcraw for reading raw files. It is notable for the advanced control it gives the user over the demosaicing and developing process.

## Compilation, patching and Git
Refer to RawPedia for dependency requirements:
http://rawpedia.rawtherapee.com/Linux

The instructions below will be merged into that article on RawPedia soon.

Clone the source code either using HTTPS:
```
git clone https://github.com/Beep6581/RawTherapee ~/repo-rt
```
or using SSH (see https://help.github.com/articles/generating-ssh-keys/ ):
```
git clone git@github.com:Beep6581/RawTherapee.git ~/repo-rt
```
or update a previously cloned repository:
```
cd ~/repo-rt && git fetch
```

Apply a patch:
If you want to apply a patch, use "git apply" if you just want to apply without committing, or "git am" if you want to automatically apply and commit:
```
git apply /downloads/some.patch
```
or
```
git am /downloads/some.patch
```

Compile:
To find out how many threads your CPU supports, run:
`grep -c processor /proc/cpuinfo`
Then replace the number in `-j8` below with this number. This will make compilation faster but it will have no effect on the speed of running RawTherapee.

Now you will make an out-of-source compilation of RawTherapee, it will be built into the ~/repo-rt/build/release folder, and then you will move this folder to your home directory and rename it to "rawtherapee", so make sure there is no ~/rawtherapee folder already!
```
mkdir build && cd build && \
cmake -DCMAKE_BUILD_TYPE="release" -DPROC_TARGET_NUMBER="2" -DBUILD_BUNDLE="ON" -DBINDIR="." -DDATADIR="." -DCACHE_NAME_SUFFIX=4 .. && \
make -j8 install && \
mv release ~/rawtherapee
```

Run RawTherapee:
`~/rawtherapee/rawtherapee`
