Short summary: cmake runs examples fine when I run it in the pre-installed src example folder, but not after I copied it to ~/shared. Could you please help see why?

Full story: first, when I run it in the pre-installed src example folder, it works:

However, if I copy the examples to my local folder, it wouldn't work. (Edit on 3/23 - removed the confusion parts of the code where I forgot to clean the old cmake file first)

(I cleaned the folder and then copied the examples to ~/shared/examples)

Could you please help?

Remove the CMakeCache.txt file. You have a problem because you first configured the test and then moved the directory. Because of that all the paths are wrong. You need to remove CMakeCache.txt in order to do a clean configure.

@Rombur Thank you Rombur for your response! Yes I tried that already and posted it in the first message, but I failed to explain it clearly enough (I did not break them up into sub paragraphs). Apologies for the confusion.

At first I did forget to remove the CMakeCache.txt:

dealii@d0e24c0315a5:~/dealii-v8.5.1-src/examples/step-1$ cp -r ~/dealii-v8.5.1-src/examples ~/shared/examples
dealii@d0e24c0315a5:~/dealii-v8.5.1-src/examples/step-1$ cd ~/shared/examples/step-1
dealii@d0e24c0315a5:~/shared/examples/step-1$ cmake CMakeLists.txt
CMake Error: The current CMakeCache.txt directory /home/dealii/shared/examples/step-1/CMakeCache.txt is different than the directory /home/dealii/dealii-v8.5.1-src/examples/step-1 where CMakeCache.txt was created. This may result in binaries being created in the wrong place. If you are not sure, reedit the CMakeCache.txt
CMake Error: The source "/home/dealii/shared/examples/step-1/CMakeLists.txt" does not match the source "/home/dealii/dealii-v8.5.1-src/examples/step-1/CMakeLists.txt" used to generate cache.  Re-run cmake with a different source directory.

So I removed all those files except for the step-1.cc and the CMakeLists.txt:

dealii@d0e24c0315a5:~/shared/examples/step-1$ ls | grep -v 'CMakeLists.txt\|step-1.cc' | xargs rm -rf
dealii@d0e24c0315a5:~/shared/examples/step-1$ ls
CMakeLists.txt  step-1.cc

And then I re-ran the cmake command, and encountered an issue where mpicc is not working:

dealii@d0e24c0315a5:~/shared/examples/step-1$ cmake CMakeLists.txt
-- The C compiler identification is GNU 6.2.0

  It fails with the following output:

@luca-heltai Thanks for you response! Yes I did - I only left step-1.cc and CMakeLists.txt, by running ls | grep -v 'CMakeLists.txt\|step-1.cc' | xargs rm -rf. And the mpicc still failed.

is the directory writeable by you?

@luca-heltai Thank you for the quick response.

  1. Yes I do - I tried the following:
dealii@4672ffbca33e:~/shared/examples/step-1$ touch test.txt
dealii@4672ffbca33e:~/shared/examples/step-1$ ls
CMakeLists.txt  step-1.cc  test.txt
  1. I had the same question yesterday, because in the CMakeError.log I read the following lines:
Determining if the C compiler works failed with the following output:
Change Dir: /home/dealii/shared/examples/step-1/CMakeFiles/CMakeTmp

Run Build Command:"/usr/bin/make" "cmTC_a147c/fast"
make: *** No rule to make target 'cmTC_a147c/fast'.  Stop.

Mmmm... it seems like it does not create directories. Can you create directories?

yw5aj commented Mar 23, 2018

@luca-heltai Yes I feel the same way - it seems like it failed to create cmTC_a147c/fast. However, it did create all the other folders like CMakeFiles, CMakeTmp. Also, I tried the following:

dealii@4672ffbca33e:~/shared/examples/step-1$ ls
CMakeLists.txt  step-1.cc
dealii@4672ffbca33e:~/shared/examples/step-1$ mkdir testdir
dealii@4672ffbca33e:~/shared/examples/step-1$ cd testdir
dealii@4672ffbca33e:~/shared/examples/step-1/testdir$ touch test.txt
dealii@4672ffbca33e:~/shared/examples/step-1/testdir$ ls
test.txt
dealii@4672ffbca33e:~/shared/examples/step-1/testdir$ cd ..
dealii@4672ffbca33e:~/shared/examples/step-1$ ls
CMakeLists.txt  step-1.cc  testdir

Maybe this could help to debug it.
