add support for QNX 7.1/8.0

[pkleymonov-qnx]

These changes facilitate porting of perl-cross for QNX7.1/8.0.
Build files are available at https://github.com/qnx-ports/build-files/tree/main/ports/perl5

NOTE: QNX ports are only supported from a Linux host operating system

Create a workspace

mkdir -p ~/qnx_workspace && cd ~/qnx_workspace
git clone https://github.com/qnx-ports/build-files.git

Clone perl5 and perl-cross repositories from tested release version perl(v5.32.0)/perl-cross(1.6.1)

git clone https://github.com/qnx-ports/perl5.git
git clone https://github.com/qnx-ports/perl-cross.git

Sync perl-cross project into perl5 main tree

cd ~/qnx_workspace
rsync -a --force --exclude='.git*' ./perl-cross/ ./perl5/

Pre-requisite:

• Install Docker on Ubuntu
  • https://docs.docker.com/engine/install/ubuntu/
• Install QNX license and SDP installation (~/.qnx and ~/qnx800 by default)
  • https://www.qnx.com/products/everywhere/ (Non-Commercial Use)

Setup a Docker container

# Build the Docker image and create a container
cd build-files/docker
./docker-build-qnx-image.sh
./docker-create-container.sh

# Now you are in the Docker container

Or setup Ubuntu host

# source qnxsdp-env.sh
source ~/qnx800/qnxsdp-env.sh

Compile the port for QNX

cd ~/qnx_workspace
# Build perl
make -C build-files/ports/perl5 JLEVEL=$(nproc)
# Install it in sysroot (QNX SDP)
make -C build-files/ports/perl5 install
# Or install it in a staging area
make -C build-files/ports/perl5 install INSTALL_ROOT_nto=<PATH_TO_YOUR_STAGING_AREA> USE_INSTALL_ROOT=true

How to run tests

Build perl5 tests and scp it to the target.

cd ~/qnx_workspace
# Build perl and all tests
make -C build-files/ports/perl5 JLEVEL=$(nproc)

# define target IP address
TARGET_HOST=<target-ip-address-or-hostname>

# remove old test dir on target
ssh qnxuser@$TARGET_HOST "rm -rf perl5_tests"

# create new test dir on target
ssh qnxuser@$TARGET_HOST "mkdir perl5_tests"

# copy perl build tree to your QNX target
scp -r build-files/ports/perl5/nto-aarch64-le/* qnxuser@$TARGET_HOST:/data/home/qnxuser/perl5_tests/
# or
scp -r build-files/ports/perl5/nto-x86_64-o/* qnxuser@$TARGET_HOST:/data/home/qnxuser/perl5_tests/

Run tests on the target.

# ssh into the target
ssh qnxuser@$TARGET_HOST

# setup perl env
cd /data/home/qnxuser/perl5_tests/t && ln -sf ../perl . && LD_LIBRARY_PATH=$(pwd):$LD_LIBRARY_PATH

# run perl tests
./perl harness
# or
./TEST

Tips and triks.

With your spd you can create and run virtual x86_64 TARGET of QNX.

# source qnxsdp-env.sh
source ~/qnx800/qnxsdp-env.sh

# Install on linux host virtual machine like qemu/vxbox/vmware
# Create and run virtual target of QNX
# qemu
mkqnximage --type=qemu --arch=x86_64 --clean --run --force --data-size=500 --data-inodes=20000
# or vmware
mkqnximage --type=vmware --arch=x86_64 --clean --run --force --data-size=500 --data-inodes=20000
# or virtual box
mkqnximage --type=vbox --arch=x86_64 --clean --run --force --data-size=500 --data-inodes=20000
