Issues about "could not locate a (sufficiently recent) version of deal.ii"

[Zhengliu Zhou]

Hi folks,

        I just finished installing deal.ii on my laptop and encountered an error somehow unexpectedly when running the tutorial program step-1, as shown in the first attachment. I could try to set the version back to 9.1.1, but then there would be some subsequent errors and I don't think it's the current version's problem. I think I have installed everything, as shown in the second attachment. Any ideas? Thank you!

There are two mistakes:
* The correct spelling is DEAL_II_DIR in the cmake invocation
* cmake wants to be called as
cmake <defines with -D> <directory to source files>
You only provide the defines, but not a path to source. For the
examples, the path to the source files is often the current directory,
i.e., "."

Prof. Bangerth,

       Thank you for your prompt reply. I fixed the two errors you mentioned, but the error remained. Could it be caused by something else? Please advise. Thank you!

Zhengliu,
what you are asked to provide is a path to a deal.II installation, not
"/path/to/deal.II". You need to replace this string by an actual directory name.

Prof. Bangerth,

      I am sorry to bother you again with such a trivial issue. Yet I still cannot resolve it. Below is a screenshot following your suggestion, but the same error remains. I suppose I didn't install something correctly? Thank you!

Dear Zhengliu Zhou,

If you don't understand how to use cmake to install the dealii, changing the installing approach to candi(https://github.com/dealii/candi) or spack(https://github.com/dealii/dealii/wiki/deal.II-in-Spack) could be better.

Best,

Chen

Hi folks,

       I followed the steps in Prof. Bangerth's lecture 8.01 about Direct project setup via CMake, but seemingly Eclipse still reports all the errors as shown below. Does anyone know why this is happening? Thank you!
