when building paraview cmake doesnt detect python 3, fortran and “opengl-xmesa”. how to proceed?
im running centos 8 with intel parallel xe (fortran compiler) with all dependencies installed.

I’m not sure what your are doing right now. Do you have these errors only when building with the patch you link ?
The “patch” is a change made in ffmpeg, that link is a piece of changelog ( series of patchs through time). When I download the last version from git of ffmpeg and build doesn’t generate the required library of cmake. Because libavresample was substituted to libswresample. If you google it " libvsvsampe deprecated" you will get a series of other packages with the same problem.
Thank you
In respect of linking fortran, python 3 there is a way to do a direct link? I don’t have an idea what cmake is requesting from “opengl xmesa”, I already have installed all libraries from Mesa and qt5, and I running the driver from Nvidia not “generic noveau”. Both gave me the same problem.
- Why do you want to build with an updated ffmpeg ?
- What does this have to do with fortran or python 3 ?
- What do you mean by direct link ?
- Why are you mentioning “opengl xmesa” ? Do you have an error message ?
What are you trying to achieve ?
How are you trying to achieve it ?
What is not working ?
Can you share an error message ?
first, im using updated ffmpeg because i dont know if an older version would run with centos8.
about fortran(now is detected), python, opengl xmesa, cmake says that didn’t found fortran and python. i have installed intel fortran and python beyond system packages of python and fortran.
direct link i meant force cmake finding the py/fortran/openglxmesa libraries.
well my primary objective is build paraview with ffmpeg and running in my nvidia driver. but im confused wich graphical renderer i use mesa, qt5 … im relatively new to linux.

What about adding a repository instead :
