This directory contains a `CMakeLists.txt`, which can be selected to open as a
|
|
project within your preferred IDE. From there, all nested examples can be built,
|
|
debugged, and ran.
|
|
|
|
Some of the more recent projects in this repository requires the latest CMake LTS.
|
|
To install `cmake` LTS with `apt` we can follow [official instructions from kitware](https://apt.kitware.com/)
|
|
Alternatively, we can install the LTS with python's `pip`.
|
|
```bash
|
|
sudo apt install python3.9 python3-pip
|
|
sudo apt purge cmake
|
|
python3.9 -m pip install -U pip
|
|
python3.9 -m pip install --upgrade cmake
|
|
# The command below is optional if you have added the python binary path to your PATH environment variable
|
|
sudo ln -s /usr/local/lib/python3.9/dist-packages/cmake/data/bin/cmake /usr/bin/
|
|
cmake --version
|
|
|
|
cmake version 3.22.1
|
|
```
|
|
|
|
Once cmake is installed, dependencies for all examples can be installed with the command below.
|
|
```bash
|
|
sudo apt install libsdl2-dev freeglut3-dev
|
|
```
|
|
|
|
If we build from this directory, we build all C++ projects and examples
|
|
```bash
|
|
cd /path/to/klips/cpp/
|
|
mkdir build && cd build
|
|
cmake .. && cmake --build .
|
|
```
|
|
|
|
We can see the binaries output in the `build/bin/` folder
|
|
```bash
|
|
~/Code/klips/cpp/build$ ls bin/
|
|
abstract-factory-test graph-test-templated SingleListDriver
|
|
adapter-test graph-test-weighted singleton-test
|
|
bridge-test HeapDriver StackDriver
|
|
bubble-sort heap-sort state-test
|
|
bucket-sort insertion-sort TemplatedDoubleListDriver
|
|
CircleDoubleDriver merge-sort TemplatedQueueDriver
|
|
CircleSingleDriver observer-test TemplatedStackDriver
|
|
columnar-transposition-test opengl-test TemplatedVectorDriver
|
|
counting-sort prototype-test test-bst
|
|
DoubleListDriver QueueDriver test-bst-algo
|
|
execute-hello quick-sort test-redblack
|
|
factory-test radix-sort VectorDriver
|
|
graph-test-object sdl-test visitor-test
|
|
graph-test-simple select-sort
|
|
```
|
|
|
|
We can also build from subdirectories.
|
|
To only build projects related to design patterns we build from the `patterns/` subdirectory, for example
|
|
```bash
|
|
cd /path/to/klips/cpp/patterns
|
|
mkdir build && cd build
|
|
cmake .. && cmake --build .
|
|
```
|
|
|
|
And we can again see the binaries output in the `build/bin/` folder
|
|
```bash
|
|
~/Code/klips/cpp/patterns/build$ ls bin/
|
|
abstract-factory-test bridge-test observer-test singleton-test visitor-test
|
|
adapter-test factory-test prototype-test state-test
|
|
```
|
|
|
|
If cmake is not being used in a project, it can be built with `g++` manually using
|
|
the commands outlined in `*/.vscode/tasks.json`, or by using VSCode to open the example
|
|
and running the build task.
|
|
Check the header comments in the main source file for the example for instructions.
