Hi there, I am attempting to install Cadabra with the source code, because neither of the Windows 10 installations are currently working (both lead to Cadabra crashing immediately upon opening).

I am following the instructions, and I am stuck on the following step:

cmake -G "Visual Studio 16 2019" -A x64 ..

I cannot figure out what those dots .. are supposed to be. If I skip this part, and just run:

cmake --build . --config RelWithDebInfo --target install

then run

ctest

all 46 of the tests fail. Any help with this part would be greatly appreciated!

Also, in case this may have caused the problem, I should probably also mention that when running the steps:

cd cadabra2 mkdir build cd build cmake -DCMAKE_TOOLCHAIN_FILE=C:/dev/vcpkg/scripts/buildsystems/vcpkg.cmake

the last step wouldn't run, because the build folder did not contain a CMakeLists.txt file. I had to change the active directory back to C:\dev\vcpkg\cadabra2, then run:

cmake -B C:\dev\vcpkg\cadabra2\build -S . -DCMAKE_TOOLCHAIN_FILE=C:/dev/vcpkg/scripts/buildsystems/vcpkg.cmake

This was all on-the-fly extrapolation from the instructions, with no prior knowledge on how to use these systems. It seemed to work ok, but I am very unsure due to my inexperience.

Ok, I've had another go at installing the program with the source code, and I'm stuck again. Here's what I am running in the "x64 Native Tools Command Prompt for VS 2019" window:

C:\dev\cadabra2\build>cmake -S "C:\dev\cadabra2" -B "C:\dev\cadabra2\build" -DCMAKE_TOOLCHAIN_FILE=C:/dev/vcpkg/scripts/buildsystems/vcpkg.cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo -DVCPKG_TARGET_TRIPLET=x64-windows -DCMAKE_INSTALL_PREFIX=C:\Cadabra -G "Visual Studio 16 2019" -A x64 ..

This produces the error:

CMake Error: Error: generator platform: x64 Does not match the platform used previously: Either remove the CMakeCache.txt file and CMakeFiles directory or choose a different binary directory.

Does anyone know a way to resolve this error?

Ok, I started from scratch. Re-installed vcpkg and cadabra, leaving the double-dots .. in this time (silly me).

I didn't run into most of the previous problems I encountered. However running ctest still leads to a 100% failure rate (output posted below). Is this normal behaviour?

I managed to fire up the notebook interface without it crashing, and I was able to process a few calculations without encountering any visible problems. Fortunately, it seems as though I can continue my work using Cadabra for now, despite these errors.
