Installation on mac "does not appear to contain CMakeLists.txt"

[Chenchen Liu]

Hi,

I downloaded the latest edition of deal.II. When I tried to build the library using the sentence "cmake -DCMAKE_INSTALL_PREFIX=/........./deal.II", it always shows the error:

CMake Error: The source directory "/" does not appear to contain CMakeLists.txt.

Specify --help for usage, or press the help button on the CMake GUI.

Also, I checked the content of deal.II folder, and I did not see any file called CMakelists.txt.

I have no idea how to pass this step. I tried to copy one CMakelists.tex file from folder "step-1" or other examples. But it gave me other error and I cannot 'make' it.

I will appreciate very much if anyone could give me some suggestions.

Best,

Chenchen

Can you please specify the *exact* command line? It need to look like this:
cmake -DCMAKE_INSTALL_PREFIX=/.../ source-dir
Note the last argument that indicates where the deal.II sources are located.

Dear Chenchen,

if you downloaded the dmg package, the deal.II library is already compiled for you.

You only need to run the “app” (which is only a terminal that sets the right environment variables for you).

Deal.II gets installed in

/Applications/deal.II.app/Contents/Resources

and you’ll find the examples in

/Applications/deal.II.app/Contents/Resources/examples/

Best,

L.

​Thank you for the quick reply.

According to the instructions for mac users, I did not realize that I should download sources files​. I thought the .dmg file will contain all the information. So, maybe I made this mistake. 

Then, I downloaded the cources files, and built the library successfully. However, when I tried to run step-1, I met the following error:

###

Do you know what is the problem?

Dear Luca,

Thank you very much for the reply. As you said, I can run examples directly without building the library. However, when I run step-1,  it gave me the following error:

bash-3.2$ cmake -DDEAL_II_DIR=/Applications/deal.II.app/

-- Autopilot invoked

-- Run   $ make info  to print a detailed help message

-- Configuring done

-- Generating done

-- Build files have been written to: /Applications/deal.II.app/Contents/Resources/examples/step-1

bash-3.2$ make run

[ 33%] Building CXX object CMakeFiles/step-1.dir/step-1.cc.o

error: invalid value 'c++14' in '-std=c++14'

make[3]: *** [CMakeFiles/step-1.dir/step-1.cc.o] Error 1

make[2]: *** [CMakeFiles/step-1.dir/all] Error 2

make[1]: *** [CMakeFiles/run.dir/rule] Error 2

Do you have any suggestions?

Thanks!

Dear Chenchen,

what version of XCode do you have installed? I have generated the package for the latest version of everything…

I’ll create a new backward compatible package as soon as I can. The error message is telling you that your compiler does not support CXX14. This can only be if you have not updated xcode, or if you have not installed its command line utilities.

I’ll update the instruction page as well.

Can you try the package that you find here:

https://github.com/dealii/dealii/releases/tag/v8.3.0

called

deal.II-8.3.0.nocxx14.dmg

?

This should be backward compatible, as it does not uses CXX14, which is not available on older macs.

Dear Luca,

Thank you so much. It works now!! I feel so happy.

Now I can move on to use deal.II. Hope everything will be fine.

Thanks again.
