在Fedora 37上构建LinuxCNC，可以按照以下步骤进行：

1. 安装依赖项：

sudo dnf install -y gcc make pkg-config libglib2.0-dev libgtk2.0-dev libglade2-dev libglu1-mesa-dev \
               mesa-common-dev libboost-python-dev libreadline-dev gettext libmodbus-dev tcl-dev tk-dev \
               libnml-dev python-dev python-tk python-gtk2-dev python-gtkglext1-dev python-opengl python-numpy \
               bwidget pycnc python-vte libboost-thread1.76.0 libboost-python1.76.0 libini-config-dev libboost-filesystem-dev \
               python3-devel swig libzmq3-devel python3-disphelper python3-numpy python3-setuptools \
               python3-pyqt5 python3-opengl PyQt5  harfbuzz-devel python3-pyparsing

2. 下载并安装LinuxCNC：

git clone https://github.com/LinuxCNC/linuxcnc.git
cd linuxcnc
git checkout 2.8
./configure
make
sudo make setuid

3. 安装且确保HAL组件正常运行：

sudo apt-get install -y libudev-dev libmodbus5 python3-tk python3-numpy python3-pil libgnomecanvasmm-2.6-dev \
               libmodbus-dev libxenomai-dev libxenomai-gchdrv-dev libboost-filesystem-dev libboost-thread-dev \
               python3-virtualenv virtualenv hal hal-python rtai-dev rtai-source rtai-doc rtai-modules-dkms \
               libgtk2.0 gtk2-engines-pixbuf libncurses5-dev libzip-dev libssh-dev build-essential intltool libtool automake autoconf \
               libboost-python-dev libboost-thread-dev libboost-system-dev libgl1-mesa-dev libglu1-mesa-dev tcl8.6-dev \
               tk8.6-dev python3-gtkglext1 libglade2-dev libzmq3-dev python3-pyzmq python3-protobuf \
               protobuf-compiler python3-six python3-cffi python3-pyasn1 python3-pyasn1-modules python3-pip libffi-dev \
               python3-wheel python3-pil.imagetk libgnome2-dev
sudo update-alternatives --set rtai-config /usr/sbin/rtai-config-3.8.2
cd linuxcnc
halrun

在完成上述步骤后，就可以在Fedora 37上运行LinuxCNC了。
