HOWTO BUILD
cross is used for cross compiling zkgroup.
-
download new release from
https://github.com/signalapp/zkgroup/releases -
unzip + change into directory
-
run
cross build --target x86_64-unknown-linux-gnu --releaserun
cross build --target armv7-unknown-linux-gnueabihf --releaserun
cross build --target aarch64-unknown-linux-gnu --releaseto build the library forx86-64,armv7andarm64 -
the built library will be in the
target/<architecture>/releasefolder
Why?
Building zkgroup every time a new docker image gets released takes really long (especially for cross platform builds with docker/buildx and QEMU). Furthermore, due to this bug here (https://github.com/docker/buildx/issues/395) we would need to use an ugly workaround for that right now. As zkgroup isn't released very often I guess it's okay to manually build a new version once in a while.
