CMake error while building and installing dolfinx c++ core

installation
1

So I just followed the instructions right away as they’re available in github at GitHub - FEniCS/dolfinx: Next generation FEniCS problem solving environment, but there comes an error when I use the command cmake …/ on the ubuntu terminal. It displays this message:

CMake Error at CMakeLists.txt:119 (find_package):

By not providing “Findpugixml.cmake” in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by “pugixml”, but
CMake did not find one.

Could not find a package configuration file provided by “pugixml” with any
of the following names:

pugixmlConfig.cmake
pugixml-config.cmake

Add the installation prefix of “pugixml” to CMAKE_PREFIX_PATH or set
“pugixml_DIR” to a directory containing one of the above files. If
“pugixml” provides a separate development package or SDK, be sure it has
been installed.

– Configuring incomplete, errors occurred!
See also “/mnt/d/A–X/FEniCSx/dolfinx/cpp/build/CMakeFiles/CMakeOutput.log”.

I don’t know how to deal with it. If someone can help, I’d appreciate your time a lot.

As the error message says, you need to install “pugixml”
See: Installation — DOLFINx 0.6.0.0 documentation
for an extensive list of dependencies

Thanks for your reply! I checked but it looks like it is installed already. The problem I thing is about those two files named pugixmlConfig.cmake and the other one. Or maybe I’m a bit confused and I’m doing something wrong, but so far, I think it should be right but still there’s that error.

Where is it installed? What is the path to the installation?

5

I think this is the path: /mnt/d/A–X/cpp/pugixml-1.13 (if I’m doing things right… I’m a bit novice with installing c++ packages)

6

As this does not look like a standard installation location (what os are you using?),
You should set either

  1. pugixml_DIR
    Or append the path to
  2. CMAKE_PREFIX_PATH

Is there a specific reason for not using any of the other installation options (conda, spack or docker)?

7

I’m using WSL with Ubuntu.

I think I could fix the mistake about pugixml, but now I get this message when I try to cmake …/ on the build directory:

But I don’t know how to fix it :confused: sorry for so much bothering

8

Oh, and I wanted to learn how to install from source, but I think I’m getting used to it and also it’s a nice chance to learn rn :slight_smile:

9

As the output tells you, you are missing PETSc and UFCx, which are both listed in:

As a side note, I rarely install all the dependencies by hand, even as a developer. If you want a guide as to how to install everything from scratch on ubuntu, i would follow the Dockerfile:
https://github.com/FEniCS/dolfinx/blob/main/docker/Dockerfile
as it lists all the commands we run on a ubuntu 22.04 system, and is used for our CI

Thank you, I think I made it. Now I got a message error when I try to run a demo: (demo_poisson.py)

I think this means I could install it properly somehow

11

Seems like you have installed a non compatible version of basix. What is the output of python3 -m pip list?

12

It’s this:

basix                         0.0.4

Here are all the packages, just in case:

As you can see here, you have installed the 0.4.X version of ffcx and dolfinx and the 0.5.X version of Basix. These are not compatible.
Also note that you should upgrade your ufl installation

Thank you! It changed, but I keep getting errors when I try to run some example:

Could you try running the basix tests?
It seems like you are using avery old version of PETSc (3.12).

Dolifnx uses petsc 3.15 as minimum:

Could you post the output of building DOLFINx in C++, and the output of echo $PETSC_DIR echo $PETSC_ARCH, as well as python3 -c "import petsc4py; print(petsc4py.__version__)"

16

As you can see here, your petsc4py is out of date

17

Now I updated to version 3.18.2.

I’m not sure how to get these ‘tests’ and the ‘building in C++’. But the other commands’ outputs (PETSC DIR and ARCH) are empty.

18

When you call cmake ../ in the DOLFINx folder, what is your output (similar to what you posted above).
To get the basix tests, go into the basix repository, then /python/test

19

This is the output I get:
