Ubuntu 20.04

1. Install basic libraries

First install required development packages using apt-get

sudo apt install -y build-essential cmake git # basic compiler libraries if needed

sudo apt install -y libboost-all-dev libphysfs-dev liblua5.1-dev libssl-dev
sudo apt install -y libglew-dev libvorbis-dev libopenal-dev zlib1g-dev
sudo apt install -y liblzma-dev nlohmann-json3-dev

and if you are using 18.04, you may also need sudo apt-get install -y libogg-dev

2. Manually install protobuf library

Protobuf from ubuntu's apt repository is outdated and will fail You'll require installing protobuf as well. To do so you have to compile it by youself.

First, get the source code:

git clone https://github.com/protocolbuffers/protobuf.git
cd protobuf
git checkout v3.19.4 # or find latest stable version

git submodule update --init --recursive
./autogen.sh

To build:

./configure
make
make check
sudo make install
sudo ldconfig # refresh shared library cache.

If you find any problem during this process, you can find more information here.

3. Installing otclient

Get the sources, compile and run

git clone git://github.com/mehah/otclient.git
cd otclient && mkdir build && cd build
cmake ..
make

4. Common Ubuntu problems:

4.1 libphysfs.a

If you have any error about missing libphysfs.a at the end of the make process, then do install physfs manually like this:

sudo apt install -y libncurses5-dev
git clone https://github.com/icculus/physfs.git
cd physfs; git checkout stable-3.0; mkdir build; cd build
cmake ..
make
sudo make install
  • Try again. If the problem persist then do:
sudo mv /usr/local/lib/libphysfs.a /usr/lib/x86_64-linux-gnu/.

4.2 libvorbis.a

If you have any error about libvorbis.a at the end of the make process, then remove everything and run cmake with these arguments:

cd build;
rm -fr *;
cmake .. -DVORBISFILE_LIBRARY:FILEPATH=/usr/lib/x86_64-linux-gnu/libvorbisfile.so -DVORBIS_LIBRARY:FILEPATH=/usr/lib/x86_64-linux-gnu/libvorbis.so

4.3 Compiling protobuf generated codes

Make sure you did install protobuf from step 2.

If you still have any error when building *.pb.cc or *.pb.h files, maybe you'll need to regenerate those files.

cd src/framework/protobuf/proto/
./generate.sh
  • Try compiling again.

5. Run the client

Once the make process has finished correctly, you can just execute otclient file inside the build folder.

./otclient

6. Updating

After any modification or git pull, just execute make again to recompile. If there have been any cmake modifications, you might need to execute the cmake command again too.

7. Tips

If you want to speed up the make process and you have multiple cores, you can use -j to build using multiple cores.

For example, to build using 8 cores:

make -j8
