cardano-node: error while loading shared libraries: libsecp256k1.so.0:

Question

I compiled cardano-node 1.35.3 on another Ubuntu box and copied over, but it seems a library is missing.

cardano-node: error while loading shared libraries: libsecp256k1.so.0: cannot open shared object file: No such file or directory

What can I do to fix this?

Answer 1

You need to download, compile and install libsecp256k1:

git clone https://github.com/bitcoin-core/secp256k1
cd secp256k1
git checkout ac83be33
./autogen.sh
./configure --enable-module-schnorrsig --enable-experimental
make
make check
sudo make install
sudo ldconfig

Answer 2

Only took my second node for me to realize there is a line missing from the https://developers.cardano.org/docs/get-started/installing-cardano-node version. The line below is missing from the docs but you can see it in sunapi386's answer

sudo ldconfig
