Problems with the build #912

Closed lucaAnza closed 8 months ago

lucaAnza commented 8 months ago

After i execute this scripts

# Get Pangolin
cd ~/your_fav_code_directory
git clone --recursive https://github.com/stevenlovegrove/Pangolin.git
cd Pangolin

# Install dependencies (as described above, or your preferred method)
./scripts/install_prerequisites.sh recommended

# Configure and build
cmake -B build
cmake --build build

# with Ninja for faster builds (sudo apt install ninja-build)
cmake -B build -GNinja
cmake --build build

# GIVEME THE PYTHON STUFF!!!! (Check the output to verify selected python version)
cmake --build build -t pypangolin_pip_install

# Run me some tests! (Requires Catch2 which must be manually installed on Ubuntu.)
cmake -B build -G Ninja -D BUILD_TESTS=ON
cmake --build build
cd build
ctest

It returns this error:

I am actually using Linux Mint 21.3

The error is shown in the first three lines:

CMake Error: Error: generator : Ninja
Does not match the generator used previously: Unix Makefiles
Either remove the CMakeCache.txt file and CMakeFiles directory or choose a different binary directory.

The code block in the documentation is not a script and you are not supposed to run all the commands. You have to decide if you want to build with the default generator:

cmake -B build
cmake --build build

or use Ninja:

cmake -B build -GNinja
cmake --build build

Can you build Pangolin if you only run either of those commands?

lucaAnza commented 8 months ago

When i use cmake -B build it prints.

I can't understand if it is build correctly. And i don't know how to see if it works. Thank you for the support!

christian-rauch commented 8 months ago

You should probably look up some documentation about how to use CMake etc.

The last lines in the log show you that a couple of executables have been built, e.g. SimpleDisplay. They are somewhere in your build folder. Try ./build/examples/SimpleDisplay/SimpleDisplay.

I am closing this since there is no issue with building Pangolin.
