Deal.ii insttallation issues

[Malik Tahiyat]

I was trying to follow this command in READ me section (after downloading and unpacking the dealii-9.1.1.tar.gz to set install directory of deal.II 

  cmake -DCMAKE_INSTALL_PREFIX=/path/to/install/dir ../deal.II   

i had changed it to cmake -DCMAKE_INSTALL_PREFIX=/home/projects/deal.II/

However, everytime I got the following error
CMake Error: The source directory "/home/malik/projects/dealii-9.1.1/build" does not appear to contain CMakeLists.txt.
Specify --help for usage, or press the help button on the CMake GUI.

The only way it worked was if i added two dots after the command: 

$ cmake -DCMAKE_INSTALL_PREFIX=/home/projects/deal.II/ ..

But then, the installation does not happen in the deal.II directory. THe program is installed in ~/projects/dealii-9.1.1/build

THe deal.II folder stays empty

ANd of course i face the error

  *** 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.

I am fairly new to linux. Can you please say what is happening wrong here?

I will be obliged.

Hi,

To install deal.II, you need to first compile it using `make` which probably happens in ~/projects/dealii-9.1.1/build and then it needs to be installed using `make install`. That second step should move the important files to /home/projects/deal.II It looks to me that you forgot this second step.

Best,

Bruno

Malik,

There is three different directories at play:
1. build directory (this is where you run cmake in)
2. the source directory (this is the deal.II download and contains
CMakeLists.txt and source/ include/, etc.)
3. the install directory

All three directories can be anything you want. For example I might use:
1. ~/dealii-9.1.1/build/
2. ~/dealii-9.1.1/
3. ~/dealii-9.1.1-installed/

In that case I would:
mkdir ~/dealii-9.1.1/build/
cd ~/dealii-9.1.1/build/
cmake -D CMAKE_INSTALL_PREFIX=~/dealii-9.1.1-installed/ ~/dealii-9.1.1/
make -j 4
make install

If that doesn't work for you, tell us exactly what command you run in
which directory.

Timo,

Thaks for your reply.

I did the exact same thing you asked.

It gives an error: 

CMake Error: The source directory "/home/malik/dealii-9.1.1" does not exist.

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

when I run the following line: cmake -D CMAKE_INSTALL_PREFIX=~/dealii-9.1.1-installed/ ~/dealii-9.1.1/

in this directory: ~/dealii-9.1.1/build/

But the directory exists!! 

How do I solve this error?

Hi Bruno,

Thanks for your reply. But the step: 

cmake -DCMAKE_INSTALL_PREFIX=/path/to/install/dir ../deal.II 

comes before the 'make' step, right?

I am getting the issue while running the aforementioned command that wither the source directory does not contain CMakelist or the source directory does not exist.

In the code sequence: 

1. mkdir ~/dealii-9.1.1/build/

2. cd ~/dealii-9.1.1/build/
3. cmake -D CMAKE_INSTALL_PREFIX=~/dealii-9.1.1-installed/ ~/dealii-9.1.1/
4. make -j 4
5. make install

I get the error : "Make Error: The source directory "/home/malik/dealii-9.1.1" does not exist." in step 3

Any help is appreciated

Does "/home/malik/dealii-9.1.1" contain a CMakeLists.txt file?

Yes it does.

I wonder if there is a problem because of the . in the directory name.
Can you try to rename the directories?

I did try it actually before. Still no results.

I am very confused what the problem is. The issue happens with the install prefix line.

I have you tried writing the full path instead of using ~ I am not
sure CMake knows how to expand it.

Start from scratch. Delete the directory that you are currently working in,
copy the .tar.gz file, and then write down *every* command you issue and error
you get as a result. Then show us this list of commands + errors. Maybe one of
us will see what the problem is!

Dear Professor Bangerth,

Thank you very much for your reply. Removing all and redoing everything definitely did the trick. Everything seems to work now.

I only did the following changes though I am not sure how useful they are: 

1. I used tar xvf instead of gunzip & tar 

2. while naming directory using home/projects/deal_installed was giving an error. Shifting to ~/projects.deal_installed had success

Thank you so much everyone for your kind support.
