Error in p4est installation using deal.II suggested script

[Kishore Nori]

Hi everyone,

Hope you are doing well!

I  am new to deal.II and I am trying to install p4est before I install deal.II, I found this script on the deal.II website (https://www.dealii.org/current/external-libs/p4est.html) for installing p4est with optimisations and settings relevant for deal.II, but I am getting an error while installing through this procedure, the following are the run time updates, when executing: $ ./p4est-setup.sh p4est-2.2.tar.gz ~/bin/

CFLAGS_FAST: -O2 -qopenmp

CFLAGS_DEBUG: -O0 -g -qopenmp

This script tries to unpack, configure and build the p4est library.

Build FAST: /home/kishore/p4est-build/FAST

Build DEBUG: /home/kishore/p4est-build/DEBUG

Install FAST: /home/kishore/bin//FAST

Install DEBUG: /home/kishore/bin//DEBUG

Checking environment: CFLAGS P4EST_CFLAGS_FAST P4EST_CFLAGS_DEBUG

Unpack directory: /home/kishore/p4est-2.2

Unpacking... done

See output in files .../config.output and .../make.output

Build FAST version in /home/kishore/p4est-build/FAST

configure: error: unsafe srcdir value: '/home/kishore/p4est-2.2'

Error: Error in configure

May I get pointers on fixing this? 

Thank you very much,

yours sincerely,

Kishore

Kishore,

Can you try the following command:

$  bash ./p4est-setup.sh p4est-2.2.tar.gz /home/kishore/bin

Best,

Bruno

Dear Bruno,

Thank you for the suggestion, but unfortunately, this as well leads to exactly the same error report as above.

I get the same error report even when I run it as a super user. (I forgot to mention that I am running this on Ubuntu 20.04)

Thanking you,

Best wishes,

Kishore

Kishore,

Can you check that /home/kishore/p4est-2.2 exists and that there are
files in the directory. According to google this error usually if
there is a blank space in the name of the file but it doesn't look
like it's your problem.

Best,

Bruno

For Ubuntu 20.04:

Have you tried to use the ppa package found here?

https://launchpad.net/~ginggs/+archive/ubuntu/deal.ii-9.2.0-backports

Doing this and running

sudo apt install libdeal.ii-dev libdeal.ii-doc cmake make g++

should install all necessary dependencies (and a functional deal.II
9.2.0). If you want to use the development version, just install version
9.2.0 on the system and then configure and compile the library by hand.

Best,
Matthias

Dear Bruno, 

Thank you again, I deleted the existing files and all the folders related to p4est and the logs and tried running the command you mentioned again, The error mentioned above is fixed but I get a new error:

configure: error: linking to Fortran libraries from C fails
See `config.log' for more details
Error: Error in configure

Best wishes,

Kishore

Dear Matthias,

No, I haven't tried this way, seems easier, thank you very much! 

Would it also install p4est? If not, can I use this way after installing p4est?

Best wishes,

Kishore

Kishore,

Do you have gfortran installed? p4est needs to have a fortran compiler
to configure even though they don't use fortran,

Best,

Bruno

Yes, it install p4est alongside trilinos, petsc, and most of the
supported dependencies.

Give it a try!

Dear Bruno,

Yes I have gfortran installed, when I try to install it again using $ sudo apt install gfortran, it says "gfortran is already the newest version (4:9.3.0-1ubuntu2)". 

The following I found relevant in the config.log file:

Thread model: posix

gcc version 9.3.0 (Ubuntu 9.3.0-17ubuntu1~20.04) 

configure:4338: $? = 0

configure:4327: mpif77 -V >&5

gfortran: error: unrecognized command line option '-V'

gfortran: fatal error: no input files

compilation terminated.

configure:4338: $? = 1

configure:4327: mpif77 -qversion >&5

gfortran: error: unrecognized command line option '-qversion'; did you mean '--version'?

gfortran: fatal error: no input files

compilation terminated.

and later in the file also

Thread model: posix

gcc version 9.3.0 (Ubuntu 9.3.0-17ubuntu1~20.04) 

configure:5434: $? = 0

configure:5423: mpicc -V >&5

gcc: error: unrecognized command line option '-V'

gcc: fatal error: no input files

compilation terminated.

configure:5434: $? = 1

configure:5423: mpicc -qversion >&5

gcc: error: unrecognized command line option '-qversion'; did you mean '--version'?

gcc: fatal error: no input files

compilation terminated.

configure:5434: $? = 1

configure:5438: checking whether we are using the GNU C compiler

configure:5465: mpicc -c -O2 -qopenmp -DSC_LOG_PRIORITY=SC_LP_ESSENTIAL conftest.c >&5

gcc: error: unrecognized command line option '-qopenmp'; did you mean '-fopenmp'?

The first seems to be a problem with mpif77, and this (https://askubuntu.com/questions/179256/how-do-i-install-a-fortran-77-compiler) says fortran77 compiler or libraries are not included in the gfortran package of Ubuntu (there seems to be a possibility of installing these by $ sudo apt-get install fort77) but I am not very sure of what is going on!?

So is this a problem pertaining to Ubuntu OS?

It is seems that I should follow Matthias suggestion and install through the PPA. 

Thank you very much for the inputs,

Best wishes,

Kishore
