Building Seer Qt6

Jump to bottom

Seer with Qt6 requires these components:

  • Linux
  • C++17
  • gdb with "mi" interpreter
  • CMake (3.10 or newer)
  • QT6
    • Core
    • Gui
    • Widgets
    • PrintSupport
    • Charts
    • Svg
  • When building Seer from source, you will need the QT6 "devel" packages installed on your system for your distribution.

Ubuntu 22.04 LTS requires these packages:

sudo apt install qt6-base-dev
sudo apt install libqt6charts*-dev
sudo apt install libqt6svg*-dev

OpenSuse 15.5 requires these packages:

sudo zypper install qt6-base-devel
sudo zypper install qt6-charts-devel
sudo zypper install qt6-core-devel
sudo zypper install qt6-gui-devel
sudo zypper install qt6-svg-devel

Grab the latest Seer code from GitHub.

% git clone https://github.com/epasveer/seer

Or grab a source tar file from the releases. The Qt6 version of Seer starts with version 2.0.

Setup cmake and build

% cd seer/src
% mkdir build
% cd build
% cmake -DQTVERSION=QT6 ..

  or 

% cmake ..     # Defaults to Qt6


% make seergdb

Some common cmake settings can be specified.

% cmake -DQTVERSION=QT6 -DCMAKE_BUILD_TYPE=Debug ..     # Debug release -g.
% cmake -DQTVERSION=QT6 -DCMAKE_BUILD_TYPE=Release ..   # Optimized release -O.
% cmake -DQTVERSION=QT6 -DCMAKE_CXX_FLAGS=-Wall ..      # With all compile warnings turned on.

Copy the Seer binary to your bin directory of choice. One of the below. May need root access.

% cd seer/src/build
% cp seergdb ~/bin/seergdb
% cp seergdb /usr/local/bin/seergdb
% cp seergdb /usr/bin/seergdb
% rehash

Or use the 'install' make target, which will usually copy it to /usr/local/bin. May need root access.

% cd seer/src/build
% sudo make install

For Debian based releases, you can use the normal tooling to build a .deb package containing Seer. You need the build-essential package installed.

% cd seer
% dpkg-buildpackage

For building on MacOS, you most likely need to provide cmake the location of your Qt6 installation. There's lots of info on the web. Here's one source.

However, you can try one of these ways. The first manually specifies where the Qt6 is installed. The second asks brew.

% cmake -DQTVERSION=QT6 -DCMAKE_PREFIX_PATH=/usr/local/opt/qt6/ ..
% cmake -DQTVERSION=QT6 -DCMAKE_PREFIX_PATH=$(brew --prefix qt6) ..

Note, if you get this error, you are likely using a C++ compiler that doesn't support c++17, which QT6 requires. Check your C++ installation.

/usr/include/qt6/QtCore/qfile.h:13:10: fatal error: filesystem: No such file or directory
 #include <filesystem>
          ^~~~~~~~~~~~
compilation terminated.

Try specifying a more recent g++ and gcc compiler to cmake. Check which compiler is installed on your system.

    % cmake -D CMAKE_C_COMPILER=gcc-10 -D CMAKE_CXX_COMPILER=g++-10 -DQTVERSION=QT6 -DCMAKE_BUILD_TYPE=Debug ..
