Installation

Linux

Several packages are required to build CalcMySky.

On Ubuntu 20.04 they can be installed by the following command:

sudo apt install git cmake g++ libeigen3-dev libglm-dev libqt5opengl5-dev

On Fedora 35 the command is

sudo dnf install cmake gcc-c++ eigen3-devel glm-devel qt5-qttools-devel

To fetch and build CalcMySky, in a terminal issue the following commands, changing the number in -DQT_VERSION=5 option to 6 if you're using Qt6:

git clone https://github.com/10110111/CalcMySky
cd CalcMySky
mkdir build
cd build
cmake .. -DQT_VERSION=5
make

To install (by default into /usr/local), issue

sudo make install

Windows

WARNING: these instructions haven't been tested. The actual Windows builds were done via AppVeyor, using .appveyor.yml script in the root of the CalcMySky source tree.

The following instructions assume that the required packages are installed as follows:

• Visual Studio 16 2019 is used;
• CMake in such a way that its cmake.exe executable is accesible via the %PATH% environment variable;
• Qt5 or Qt6 in the directory described by %QT_BASEDIR% environment variable (there should exist %QT_BASEDIR%\bin directory);
• GLM in C:/glm;
• Eigen3 in C:/eigen (there should exist C:/eigen/share/eigen3/cmake directory).

In the terminal cd into the directory with CalcMySky unarchived, and run the following commands, changing the number in -DQT_VERSION=6 option to 5 if you're using Qt5:

mkdir build install
cd build
set PATH=%PATH%;%QT_BASEDIR%\bin
cmake -G "Visual Studio 16 2019" -DCMAKE_CXX_FLAGS="/IC:/glm" -DCMAKE_PREFIX_PATH="C:/eigen/share/eigen3/cmake" -DCMAKE_INSTALL_PREFIX=../install ../CalcMySky -DQT_VERSION=6
cmake --build . --config Release
cmake --build . --config Release --target install
cp -rv ../CalcMySky/examples ../install/CalcMySky

The output of these commands is the install/CalcMySky directory in the source tree.

macOS

Several packages are required to build CalcMySky. They can be installed using HomeBrew by the following command:

brew install cmake qt@6 glm eigen

To fetch and build CalcMySky, in a terminal issue the following commands, changing the number in qtVer=6 option to 5 if you're using Qt5:

git clone https://github.com/10110111/CalcMySky
mkdir build && cd build
qtVer=6
qtPath=/usr/local/Cellar/qt/$qtVer.*
export PATH=$qtPath/bin:$PATH
cmake ../CalcMySky -DCMAKE_BUILD_TYPE=Release \
                   -DCMAKE_INSTALL_PREFIX="$PWD/install/CalcMySky" \
                   -DQT_VERSION=$qtVer \
                   -DCMAKE_PREFIX_PATH="$(echo /usr/local/Cellar/eigen/*/share/eigen3/cmake)" \
                   -DCMAKE_CXX_FLAGS="-I$(echo /usr/local/Cellar/glm/*/include)"
cmake --build .

To install, issue

cmake --build . --target install

This will install into the path specified by -DCMAKE_INSTALL_PREFIX=... option above.
