add support QNX 7.1/8.0

[pkleymonov-qnx]

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

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 asio repository from tested release version

git clone https://github.com/qnx-ports/asio.git

Or clone it from original repository

git clone https://github.com/chriskohlhoff/asio.git

Generate GNU build tool ./configure and all needed Makefiles

cd asio/asio
./autogen.sh
cd -

Setup a Docker container

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)

# 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

Compile the port for QNX

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

How to run tests

Build asio test and scp it to the QNX target.

cd ~/qnx_workspace
# Build asio test and install it in sysroot (QNX SDP)
make -C build-files/ports/asio check JLEVEL=$(nproc)

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

# copy asio test binaries to your QNX target
scp -r $QNX_TARGET/aarch64le/usr/local/bin/asio_tests qnxuser@$TARGET_HOST:/data/home/qnxuser/
# or
scp -r $QNX_TARGET/x86_64/usr/local/bin/asio_tests qnxuser@$TARGET_HOST:/data/home/qnxuser/

Run tests on the target.

# ssh into the target
ssh qnxuser@$TARGET_HOST

## Run asio tests
cd /data/home/qnxuser/asio_tests/
./run_testsuites.sh

New performance tests have to be proper configured
