Build hangs when Running custom install script libcamera/src/ipa/ipa-sign-install.sh

[PeterQFR]

When Building libcamera I commonly have issues where the installation will hang indefinitely regenerating signatures in the above script. This is when cross-compiling using docker buildx command on an x86_64 system targeting an aarch64 architecture.

Specifically on the line:

 236.5 Running custom install script '/libcamera/src/ipa/ipa-sign-install.sh /libcamera/build/src/ipa-priv-key.pem lib/aarch64-linux-gnu/libcamera/ipa/ipa_rpi_vc4.so lib/aarch64-linux-gnu/libcamera/ipa/ipa_rpi_pisp.so'

The build will hang, not error and will spin for a long > 50000s time. On successful builds, on raspberry 4 it will typically only take 500s.

Steps to Reproduce
This occurs in a dockerfile such as

FROM ubuntu:20.04


RUN export DEBIAN_FRONTEND=noninteractive &&\
        apt update -qq && apt install -y software-properties-common && add-apt-repository universe \
        && apt update &&  apt install -y curl \
        && curl -sSL https://raw.githubusercontent.com/ros/rosdistro/master/ros.key -o /usr/share/keyrings/ros-archive-keyring.gpg \
        && echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/ros-archive-keyring.gpg] http://packages.ros.org/ros2/ubuntu $(. /etc/os-release && echo $UBUNTU_CODENAME) main" | tee /etc/apt/sources.list.d/ros2.list > /dev/null \
        && apt update && apt upgrade -y \
        && apt-get install -qq -y \
        ros-galactic-ros-base \
        ros-dev-tools

RUN pip3 install meson>=0.63 ninja Jinja2

RUN git clone https://github.com/raspberrypi/libcamera.git && cd libcamera && \
	export CFLAGS="-Wno-error" && meson setup build --buildtype=release -Dpipelines=rpi/vc4,rpi/pisp -Dipas=rpi/vc4,rpi/pisp \

being built on an ubuntu host system (x86_64 in crosscompile via docker buildx using the following command:

docker buildx build --platform linux/aarch64  -t ros2  -f ros2/Dockerfile ros2

I have tried checking out versions where it has worked ie v0.5.0, but the error remains. The system has sufficient resources to complete this action. It last worked on a rpi 4 with debian bookworm as the host system.

Just confirming that a clean cache on a Raspberri4 running rasparian does complete without errors in a docker environment.

So does this hang/lockup only occur when you are cross compiling, and compiling on a Raspberry Pi 4 works as expected?
