Enabling Bitcoin Core Wallet during configuration? Getting "method not found"

The problem: I'm getting "Method not found" when running bitcoin-cli getwalletinfo on a new install.

I've compiled and installed Bitcoin Core 26.0 from source on a Ubuntu system, following the standard method:

./autogen.sh./configuremake make install 

I had to install a few missing modules (including gcc) but once done everything seemed to work correctly, and bitcoind is now happily downloading the blockchain. I didn't specify any additional commands to the configure script. However when I run bitcoin-cli getwalletinfo I get 'Method not found'.

If I run bitcoin-cli help |grep -i wallet then no results are returned.

I've checked and the disablewallet line in my bitcoin.conf is commented out. I tried flipping it to 0 just in case, no difference.

Looking in config.log in the build directory, I see this:

configure:34644: checking whether to build bitcoin-walletconfigure:34654: result: yes...configure:34826: checking if wallet should be enabledconfigure:34837: result: no

Is this what's causing the problem, and if so, how do I fix it? Or if not, what else should I be looking at?
