CMakeLists.txt misses definition of 'print_error' about sundials HOT 8 CLOSED

ETA: Wow, I feel dumb. One of the install guides I had originally looked at (this one) was very old and tar xfz ../sun_cmake.tar.gz is deprecated. Works perfectly now I think! Thanks @balos1

I ran into a similar error when running cmake .. -c ../cmakelists.txt from /build. I'm horribly unfamiliar with cmake so maybe I shouldn't do that either...

I've also tried copy/pasted from the README: cmake -DCMAKE_INSTALL_PREFIX=/mnt/shared/sundials-5.6.1/inst -DEXAMPLES_INSTALL_PATH=/mnt/shared/sundials-5.6.1/inst/examples ../src which returns another unknown command error Unknown CMake command "add_prefix". @gardner48 do you know whether these are related and if I forgot to point to a header file somewhere with all these include statements?

@apigott Try cmake -DCMAKE_INSTALL_PREFIX=/mnt/shared/sundials-5.6.1/inst -DEXAMPLES_INSTALL_PATH=/mnt/shared/sundials-5.6.1/inst/examples ../ instead. On your first run of CMake, the ../ should give the path to the root of SUNDIALS, not the src/ directory within SUNDIALS.

Thanks for the quick reply! That actually gets me back to the original print_error for CMAKE_SOURCE_DIR == CMAKE_BINARY_DIR... I should be building in the /build right?

ETA: echo $CMAKE_BINARY_DIR and $CMAKE_SOURCE_DIR are both empty variables

@apigott Assuming you have this layout:

sundials
├── CMakeLists.txt
├── CONTRIBUTING.md
├── INSTALL_GUIDE.pdf
├── LICENSE
├── NOTICE
├── README.md
├── build
├── cmake
├── doc
├── examples
├── include
├── src
└── test

Then, from inside the build directory, cmake -DCMAKE_INSTALL_PREFIX=/mnt/shared/sundials-5.6.1/inst -DEXAMPLES_INSTALL_PATH=/mnt/shared/sundials-5.6.1/inst/examples ../ should work. If it does not, delete your build directory, create it again, and retry the cmake command.

Hm. That didn't work so I tried tar-ing again. From the beginning:

tar xfz ../sun_cmake.tar.gz
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=/mnt/shared/sundials-5.6.1/inst -DEXAMPLES_INSTALL_PATH=/mnt/shared/sundials-5.6.1/inst/examples ../

doesn't work. It's an error about the config file CMake Error: File /mnt/shared/sundials-5.6.1/src/sundials/sundials_config.in does not exist. It's been about a week since I could work on this but I think last time I fixed that error by copy/pasting the config settings. (IIRC, from here)

@apigott Try this:

git clone https://github.com/LLNL/sundials.git
cd sundials
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=/mnt/shared/sundials-5.6.1/inst -DEXAMPLES_INSTALL_PATH=/mnt/shared/sundials-5.6.1/inst/examples ../

Without knowing your directory layout, it is hard to say what is going wrong. If the above procedure works, then I suspect your layout is not what I assumed it is.

This issue was addressed in the SUNDIALS v5.7.0 release.
