Installing flair on CentOS 8

mibauer · 20 February 2023 12:03

Hello experts,

I have problems installing flair on CentOS 8. I searched the forum and found solutions to some issues, but others have remained:

I use

python 3.6.8
gcc 9.3.0
c++ 9.3.0

First I tried to install flair according to the instructions for ‘Linux:Fedora,CentOS,RedHat(.rpm)’.

Beforehand I installed the required packages.
When I used the command

rpm -ivh flair-3.2-1.noarch.rpm

I received:

error: Failed dependencies:
flair-geoviewer is needed by flair-3.2-1.noarch
python3-pydicom is needed by flair-3.2-1.noarch

However, I installed the latter with the command

pip3 insall -U pydicom

When I type ‘python3’ and then 'import pydicom’, the import succeeds.
Regarding the missing geoviewer for the flair installation, I tried to install them at the same time using

rpm -ivh flair-3.2-1.noarch.rpm flair-geoviewer-3.2-1.x86_64.rpm

error: Failed dependencies:
python3-pydicom is needed by flair-3.2-1.noarch
libc.so.6(GLIBC_2.32)(64bit) is needed by flair-geoviewer-3.2-1.x86_64
libc.so.6(GLIBC_2.33)(64bit) is needed by flair-geoviewer-3.2-1.x86_64
libc.so.6(GLIBC_2.34)(64bit) is needed by flair-geoviewer-3.2-1.x86_64
libm.so.6(GLIBC_2.29)(64bit) is needed by flair-geoviewer-3.2-1.x86_64
libm.so.6(GLIBC_2.35)(64bit) is needed by flair-geoviewer-3.2-1.x86_64
libstdc++.so.6(CXXABI_1.3.13)(64bit) is needed by flair-geoviewer-3.2-1.x86_64
libstdc++.so.6(GLIBCXX_3.4.29)(64bit) is needed by flair-geoviewer-3.2-1.x86_64

Alternatively I tried to build it from source and downloaded the tgz files.
I followed the same procedure with which I successfully installed flair on MacOS from source:

untared flair
cd into the folder
command: make
Untared geoviewer
cd into the folder
command: make
save in a variable FPATH my path to flair
type (within the geoviewer directory) : make install DESTDIR=$FPATH

This latter command resulted in:

Dear Michael,

to compile python from source you will need some extra packages: python-devel and tk-devel. The actual package names may be different on Centos 8 and based on the method of how python was installed.

The .rpm package unfortunately won’t work, since it was compiled for newer distributions.

Cheers,
David

Dear David,

thanks for your help.
I found the packages you mentioned for CentOS 8 having the same name, installed them and now it works!

Thanks again,
Michael
