What is the path to the dealii installation directory in a containerized version?

[Jhon Uribe]

Hello

I am using a container from the image v9.1.1-gcc-mpi-fulldepsspack-debugrelease, but when I try to use the command "cmake -DDEAL_II_DIR=/path/to/installed/deal.II .", I don't know what to replace the string "/path/to/installed/deal.II" for.

Thank you for your attention

This is the problem:

I have the following files (in the directory /home/dealii/documents/examples_backup/step-1):

dealii@9b28e44a5519:~/documents/examples_backup/step-1$ ls
CMakeLists.txt  doc  step-1.cc

Then I write the following command:

dealii@9b28e44a5519:~/documents/examples_backup/step-1$ cmake .

And the following error is printed:

CMake Error at CMakeLists.txt:30 (MESSAGE):
 

  *** Could not locate a (sufficiently recent) version of deal.II.  ***

 

  You may want to either pass a flag -DDEAL_II_DIR=/path/to/deal.II to cmake

  or set an environment variable "DEAL_II_DIR" that contains this path.

Jhon,

the path is there, and it is correct. The message is telling you that you are in a directory containing developement version of the examples.

If you inspect the CMakeLists.txt of the example you are trying to compile, it tells you:


FIND_PACKAGE(deal.II 9.2.0 QUIET
HINTS ${deal.II_DIR} ${DEAL_II_DIR} ../ ../../ $ENV{DEAL_II_DIR}
)
IF(NOT ${deal.II_FOUND})
MESSAGE(FATAL_ERROR "\n"
"*** Could not locate a (sufficiently recent) version of deal.II. ***\n\n"
"You may want to either pass a flag -DDEAL_II_DIR=/path/to/deal.II to cmake\n"

"or set an environment variable \"DEAL_II_DIR\" that contains this path."

)
ENDIF()

i.e., I guess your program is looking for deal.II 9.2.0, but finds only 9.1.1, and bails out.

Try replacing 9.2.0 with 9.1.0 in the CMakeLists.txt, and you should be able to compile and run within docker.

Best,
Luca.
