I’m using standard Ubuntu 20.04 that is updated.
I’ve never had trouble using candi to install deal.ii before. I’ve tried everything I can think of. Thanks

Hi Gerry,
Thanks for posting to the forum.
There is no need to install PETSc with candi, as its use in ASPECT is now explicitly disabled.
In the candi.cfg file, you can normally comment out all packages (i.e., this means they won’t be built) except for Trilinos, p4est, and dealii. Other packages you might want to build, depending on what is already installed on your system, are hdf5 and openblas.
Cheers,
John

Hi John,
I get an error which says it can build Trilinos when I comment out everything but Trilinos, p4est, and dealii.
I’m starting the error messages at the beginning of the TPL part so you can see what the compiler finds and what it doesn’t:

Hi Gerry,
It looks like scalapack (and maybe other related libraries) are not installed on the machine.
The instructions in the manual are to install the following packages on Ubuntu:
```auto
sudo apt-get install build-essential \
cmake \
gcc \
g++ \
gfortran \
git \
libblas-dev \
liblapack-dev \
libopenmpi-dev \
numdiff \
openmpi-bin \
zlib1g-dev
```
Have libblas-dev and liblapack-dev been installed on your computer? These instructions were for Ubuntu 14, so we may need to update to include things like scalapack. See the following link for scalapack libraries to install, depending on the version of MPI on your machine:
[https://packages.ubuntu.com/source/bionic/scalapack](https://packages.ubuntu.com/source/bionic/scalapack)
I have built deal.II on ubuntu 20.04 with candi, but don’t recall the details of what I installed.
As an alternative, you can have candi install openblas (uncomment that package in candi.cfg) and see if that is sufficient to configure and build Trilinos.
Cheers,
John

Hi Gerry,
I might have broken the latest Candi version with a recent change. Can you please do
```auto
git remote update
git checkout v9.3.1-r1
```
and try again?

Hi Timo,
I still get a failure to build Trilinos … Do you want to see more of the errors. (BTW I’m in a detached HEAD state after git checkout v9.3.1-r1) but I assume that that doesn’t matter

Nope … How much of the output do you want? Suppose I blow away deal.ii.9.3.0 or even candi and start over?

Timo,
What do you think of the following advice? Do you know what the instructions for using “apt …” would be for 20.04. Also shouldn’t we update the manual?
Thanks!

The instructions in the manual are to install the following packages on Ubuntu:
```auto

```
Have libblas-dev and liblapack-dev been installed on your computer? These instructions were for Ubuntu 14, so we may need to update to include things like scalapack. See the following link for scalapack libraries to install, depending on the version of MPI on your machine:

Hi Gerry,
We just switched to requiring 9.3 so the instructions, manual, Candi, etc. likely still need work. I will spend some time on that soon.
Until then, it might be easiest for you to use the Ubuntu packages as you are on 20.04:
> **[Getting deal.II · dealii/dealii Wiki](https://github.com/dealii/dealii/wiki/Getting-deal.II#linux-packages)**
>
> The development repository for the deal.II finite element library. - Getting deal.II · dealii/dealii Wiki
Let us know if that works for you.

Hi all,
Gerry - I just build deal.II 9.3.1 via candi on a desktop with Ubuntu 20.04 freshly installed.
Prior to the installation, I installed all of the recommended ubuntu libraries in the manual and then also installed all of the additional recommended libraries that appear at the beginning of the candi installation process … e.g., I aborted the candi installation, installed additional packages, and then restarted the candi process.
No issues during the installation (HDF5, p4est, Trilinos, deal.II). Can you try installing all of the packages recommended by candi and then trying candi again?
John

Hi John,
Could you please send me or post the candi.cfg file that worked here and point me at the part of the manual that lists all of the recommended Ubuntu libraries?
Thanks!
