Docker build fails on MacOS

[scolear]

Trying to follow the documentation here for M1 Mac users:
https://speculos.ledger.com/user/macm1.html#how-to-build-the-docker-image

Yields the following error:

0.648 /speculos/src/bolos/cx_bls.h:4:10: fatal error: blst.h: No such file or directory

Help would be appreciated!

Hello,

You can try the following:

1. Clone speculos repo (master branch)
2. docker build -f build.Dockerfile -t speculos-builder:latest .
3. Patch Dockerfile:

diff --git a/Dockerfile b/Dockerfile
index 1ab457b..8305c93 100644
--- a/Dockerfile
+++ b/Dockerfile
@@ -4,7 +4,7 @@
 #
 # Building the Speculos environment
-FROM ghcr.io/ledgerhq/speculos-builder:latest AS builder
+FROM speculos-builder:latest AS builder

4. docker build -f Dockerfile -t speculos:latest

For your information, there is also a prebuilt Docker image supporting different architectures that can be retrieved:
docker pull ghcr.io/ledgerhq/ledger-app-builder/ledger-app-dev-tools (see https://github.com/LedgerHQ/ledger-app-builder/tree/master/dev-tools)
Docker image contains an up-to-date speculos version.

Thanks!

I have gotten further this time following your description.
I can bash into the box successfully. However, running

docker run --rm -it -v $(pwd)/apps:/speculos/apps --publish 41000:41000 --publish 5001:5001 speculos --model nanos --display headless --vnc-port 41000 --api-port 5001 apps/btc.elf

Yield the following crash report:

is there something that needs to be set up outside the container for this to work? I don't seem to find anything in the docs. Thanks!

FWIW: I was researching this one, as we've been facing the same issue, and the failure started to happen on version 0.8.4 and further, the IndexError: bytearray index out of range error seems consistent on all versions from 0.8.4 up to 0.9.1.
