 A release build of the Java bindings library for Linux is available in git. Thus, the bindings should work as long as the `LD_LIBRARY_PATH` includes the top-level directory of this repository.
 
-To build the bindings locally, the bindings require some additional work which is still making its way upstream, for now it should be built against the [rust-lightning 2020-10-java-bindings-base branch on git.bitcoin.ninja](https://git.bitcoin.ninja/?p=rust-lightning;a=shortlog;h=refs/heads/2020-10-java-bindings-base). Check that branch out locally and run the `genbindings.sh` script in it to build the required binaries. Thereafter, in this repo, run the `genbindings.sh` script with the first argument pointing to the rust-lightning directory, the second the relevant JNI CFLAGS, the third argument set to `true` or `false` to indicate whether building in debug mode, and the third set to true or false to indicate if the bindings should be built with workarounds required for Android. JNI CFLAGS on debian are likely "-I/usr/lib/jvm/java-11-openjdk-amd64/include/ -I/usr/lib/jvm/java-11-openjdk-amd64/include/linux/". When running a program linking against the library in debug mode, LD_PRELOAD should likely include the relevant `libclang_rt.asan-platform.so` path.
