can not build qtermwidget from source

问题

I'm trying to build qtermwidget from source, but it gives me error.
I've successfully built lxqt-build-tools and then installed pyqt5 from both pip3 and apt:

sudo -H pip3 install -U pyqt5 pyqtwebengine
sudo apt install python3-sip-dev python3-pyqt5

and then I ran this:

mkdir -p /tmp/EAF && cd /tmp/EAF
git clone https://github.com/lxqt/qtermwidget  
cd qtermwidget  
mkdir build && cd build  
cmake .. -DQTERMWIDGET_BUILD_PYTHON_BINDING=ON -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_INSTALL_LIBDIR=/usr

and it works fine. but when I run make command, it gives me this error:

[ 87%] Built target qtermwidget5

I'm using gcc (Ubuntu 7.4.0-1ubuntu1~18.04.1) 7.4.0 and cmake version 3.16.0 and GNU Make 4.1 in elementary OS 5.1 Hera. I once tried building sip and pyqt5 from source, didn't change anything for me.

回答1:

The PyQt5 distributed by Ubuntu does not share the necessary .sip to compile QTermWidget so it is necessary to compile sip and pyqt5 manually. It seems you tried and it didn't work since it seems you used the wrong flags. Considering the above, I analyzed how sip, pyqt5 and qtermwidget are compiled in Arch Linux and managed to implement a Dockerfile that allowed me to compile QTermWidget.

So considering the above the procedure is:

sudo apt-get update && apt-get install \
    -y --no-install-recommends \
    build-essential \
    git \
    ca-certificates \
    wget \
    cmake \
    pkg-config \
    python3-dev \
    libglib2.0-dev \
    qt5-default \
    qttools5-dev

mkdir -p /tmp/EAF

cd /tmp/EAF && \
    git clone https://github.com/lxqt/lxqt-build-tools.git \
    && cd lxqt-build-tools \
    && mkdir build && cd build \
    && cmake .. \
    && make && sudo make install

cd /tmp/EAF && \
    wget https://www.riverbankcomputing.com/static/Downloads/sip/4.19.19/sip-4.19.19.tar.gz && \
    tar xvzf sip-4.19.19.tar.gz && \
    cd sip-4.19.19 && \
    python3 configure.py --sip-module PyQt5.sip && \
    make && \
    sudo make install

cd /tmp/EAF && \
    wget https://www.riverbankcomputing.com/static/Downloads/PyQt5/5.13.2/PyQt5-5.13.2.tar.gz && \
    tar xvzf PyQt5-5.13.2.tar.gz && \
    cd PyQt5-5.13.2 && \
    python3 configure.py --confirm-license && \
    make && \
    sudo make install

cd /tmp/EAF && \
    git clone https://github.com/lxqt/qtermwidget \
    && cd qtermwidget \
    && mkdir build && cd build \
    && cmake .. -DQTERMWIDGET_BUILD_PYTHON_BINDING=ON -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_INSTALL_LIBDIR=/lib \
    && make && sudo make install
