Hello,

I cannot build Sundials 6.2.0 using cmake 3.21 on macOS : I get the following output

portmottelet-cr-1:build mottelet$ /Users/mottelet/git/CMake/bin/cmake cmake ../src -DCMAKE_INSTALL_PREFIX=/Users/mottelet/git/sundials6.2.0/inst/ -DEXAMPLES_INSTALL_PATH=/Users/mottelet/git/sundials6.2.0/examples

CMake Warning (dev) in CMakeLists.txt:
  No project() command is present.  The top-level CMakeLists.txt file must
  contain a literal, direct call to the project() command.  Add a line of
  code such as

    project(ProjectName)

  near the top of the file, but after cmake_minimum_required().

  CMake is pretending there is a "project(Project)" command on the first
  line.
This warning is for project developers.  Use -Wno-dev to suppress it.

How can I fix it ?

Thanks for help

It's a bit unclear from your post, but can you clarify the build directory structure for your call? From the first line it looks like you have something like:

git clone git@github.com:LLNL/sundials.git
cd sundials
mkdir build
cd build
/Users/mottelet/git/CMake/bin/cmake cmake ../src -DCMAKE_INSTALL_PREFIX=/Users/mottelet/git/sundials6.2.0/inst/ -DEXAMPLES_INSTALL_PATH=/Users/mottelet/git/sundials6.2.0/examples

If that is the case, then I recommend that you change your cmake command to instead be

/Users/mottelet/git/CMake/bin/cmake cmake .. -DCMAKE_INSTALL_PREFIX=/Users/mottelet/git/sundials6.2.0/inst/ -DEXAMPLES_INSTALL_PATH=/Users/mottelet/git/sundials6.2.0/examples

to ensure that CMake is directed to the top-level SUNDIALS folder, and not the src subfolder.

If that was not your setup, then could you provide a bit more information about how this is laid out for you?

Sorry, I thought that the src folder what the target (now it works).

Thanks a lot. I have another instance of 6.2.0 within Scilab but I need to build standalone examples to make some comparisons (see my other question).
