KB00003: OWFS feature setup fails on RedHat Enterprise Linux 8/Centos 8
EVA ICS versions: 3.3.2
Problem
The 1-Wire feature setup eva feature setup owfs fails with the error:
Error
Unsupported OS or distribution Error: Operation failed
Solution
Unfortunately, neither RHEL/CentOS 8 nor EPEL provide the required libow-devel package. The package from Fedora also can not be installed with rpm.
The solution is to install libow from source:
yum install -y libtool make
curl -sL https://github.com/owfs/owfs/archive/v3.2p4.tar.gz |tar xzf -
cd owfs-3.2p4
./bootstrap
./configure --prefix=/usr --disable-owtcl --disable-owphp \
--disable-owpython --disable-zero --disable-owshell --disable-owhttpd \
--disable-owftpd --disable-owserver --disable-owperl --disable-owtcl \
--disable-owtap --disable-owmon --disable-owexternal --disable-dependency-tracking
make
make install
ldconfig
After, install EVA ICS feature again with python_lib_only=1 option:
eva feature setup owfs python_lib_only=1
