Self SDK depends on some native libraries to manage encryption libself_olm and libself_omemo. Below you’ll find the instructions to get them working on your system.

Debian/Ubuntu

$ curl -O https://download.joinself.com/olm/libself-olm_0.1.17_amd64.deb
$ curl -O https://download.joinself.com/omemo/libself-omemo_0.1.2_amd64.deb
$ apt install libsodium-dev
$ apt install ./libself-olm_0.1.17_amd64.deb ./libself-omemo_0.1.2_amd64.deb

Redhat/Centos

$ rpm -Uvh https://download.joinself.com/olm/libself-olm-0.1.14-1.x86_64.rpm
$ rpm -Uvh https://download.joinself.com/omemo/libself-omemo-0.1.2-1.x86_64.rpm

Mac (x86_64)

$ brew tap joinself/crypto
$ brew install libself-olm libself-omemo

Mac (m1/arm64)

Brew on M1 macs currently lacks environment variables needed for the sdk to find the olm and omemo libraries, so you will need to add some additional configuration to your system:

In your ~/.zshrc, add:

export C_INCLUDE_PATH=/opt/homebrew/include/
export LIBRARY_PATH=$LIBRARY_PATH:/opt/homebrew/lib

You should then be able to run:

$ source ~/.zshrc
$ brew tap joinself/crypto
$ brew install --build-from-source libself-olm libself-omemo

Note, you may also need to create /usr/local/lib if it does not exist:

$ sudo mkdir /usr/local/lib
