Using PETSc from the distribution's packages

[Jeremy Theler]

Hey all

The most problematic part of compiling milonga and Fino is the PETSc/SLEPc part. Even though GNU/Linux distributions have been including binary packages of both these libraries, they usually were old versions that were not compatible with milonga and Fino. Now that development has stalled, both codes seem to work fine with any version greater that 3.6.0 which seems to be the case of most modern distributions.

I am a Debian guy, so I can tell that Debian 9 Stretch provides good packages (Debian 8 Jessie does not!).

Can others point out what the PETSc/SLEPc versions are the ones included in the latest stable releases of other distributions? If most of them (Ubuntu? what is the official distribution at IB? In my undergrad student days it was Red Hat :-) ) provide > 3.6.0 then I can update the docs to show how to use the pre-compiled libraries and make life of newcomers easier.

Any help?

Another idea is to provide statically-linked binaries, but these would be > 100Mb in size.

Regards

I'm on Fedora and CentOS:

Fedora 27 - last stable release provides:
petsc 3.8.3

CentOS (EPEL7)
petsc 3.8.3

slepc is not provided as binary packages by neither one.

Cheers,

Vitor

Hey all

I did not receive many replies on this (only Vitor's), you are probably as busy as I am.

Nevertheless, I upated the "quick start" instructions in wasora, fino and milonga.

Even though the get.sh script still works, I reverted back to stating the individual commands. If stock petsc/slepc packages can be used, the compilation workflow is straigtforward:

sudo apt-get install m4 make autoconf automake gcc g++ git findutils
sudo apt-get install libgsl-dev libsundials-serial-dev libreadline-dev petsc-dev slepc-dev

git clone https://bitbucket.org/seamplex/milonga/
cd milonga
./autogen.sh
./configure
make
make check

Besides, if one of the steps fail, it is easier to see what went wrong.

Any comment is appreciated.

regards

Dear Germán,

The petsc and slepc is the most difficult part.

I agree with using the commands steps because the problems with petsc and sleps happen the first time. After that I learnt the steps and I compiled with the steps.

Regards.
