Error while installing: "no configuration information is in src/secp256k1"

[zerotobtc]

I am trying to install libwally on my debian machine. I followed the installation guide but running ./configureI got the warning

=== configuring in src/secp256k1 (/home/standup/libwally-core/src/secp256k1)
configure: WARNING: no configuration information is in src/secp256k1

so when I run make I get the error

make[2]: Entering directory '/home/standup/libwally-core/src'

I see that it's an issue with the secp256k1 so I did some research and found this suggestion to install secp256k1 seperately in the /src directory (I simply cloned the repo and built it within /src). This brought me a bit further (no warning while running ./configure) but I still get this error after running make:

There is no secp256k1/include/secp256k1_ecdsa_s2c.h file ...

How can I fix this? It already seemed strange to me that I had to install the secp256k1 manually...

I installed the fork of bitcoin-core's secp256k1 manually, now it works.

Hi @zerotobtc

I think you may have missed the README section on building:

# Initialise the libsecp sources (Needs to be run only once)
$ git submodule init
$ git submodule sync --recursive
$ git submodule update --init --recursive

This will sync libsecp sources using git submodules rather than you cloning a potentially incompatible version yourself.

Also in the current branch, you can build with the standard libsecp sources if you wish using --enable-standard-secp, although this will disable some features such as elements support.

For posterity, this is missing from the Ubuntu instructions.
