[tuto] 8.3.5, openSUSE Tumbleweed, installation

[promeneur]

For those who want the beta version and an almost easy installation.

Install fah-client-bastet-alpha rpm.

Get the beta version (8.3.5) of fah-client executable from
https://download.foldingathome.org/rele ... se.tar.bz2

Give to "root" the right to modify /usr/bin/ folder
As "root", replace the alpha version of fah-client executable by the beta version of fah-client in /usr/bin/ .
Give to root the right to only read the /usr/bin/ folder.

Restart your PC.

Beta 8.3.5 is available at https://software.opensuse.org/package/f ... astet-beta

I will remove the alpha package soon, unless there's an explicit need for it.

cbang packaging machinery is working fine on Fedora/RHEL and openSUSE. Give viewtopic.php?p=363756#p363756 a try (you can git checkout the release tags before building).

I'm not the least bit interested in local builds that rape rpmbuild. I'm using this https://build.opensuse.org which results in 5 repositories there https://software.opensuse.org/package/f ... stet-alpha

To all openSUSE users: Please switch to package "fah-client-bastet-alpha".

OBS can build for Fedora/RHEL, right?

We could tweak your spec with

Code: Select all

%if 0%{?sle_version}
    foo
%else
    bar
%endif

or so for the divergent options. Please use upstream service file and merge there any useful options, dropping useless stuff like RuntimeDirectory=, PIDFile=, EnvironmentFile=, ExecStartPost=, ExecStop=, possible others.

Are you packging /var/lib/fah-client directory?

Code: Select all

%attr (0750, %_name, %_name) /var/lib/%{_name}

Missing "%dir" here?

For the sandbox I think we should add RestrictSUIDSGID=yes and RemoveIPC=yes to the upstream file. With them our settings basically map to the same ones auto applied when DynamicUser=yes is in use. But require much newer systemd (242 and 248), not supported on RHEL 8 (239), Debian 10 (241), Debian 11 (247). It should work anyway, only print a warning.

Also Wants=network-online.target is a big hammer we should avoid. Joseph made some changes to make the client more robust in case of missing network at startup. It should not require this anymore. syslog.target does not exist for more than decade. remote-fs.target is not needed...

CPUSchedulingPolicy=idle is probably too much (and I am not sure it is actually applied to child processes). This approach is better IMHO:

OBS can build for Fedora/RHEL, right?

Yes, it could. It fails with RHEL-7, because 'BuildRequires: scons' can't be resolved.
Fedora-40 looks better, however a couple of adaptions are required.

Please use upstream service file and merge there any useful options, dropping useless stuff like RuntimeDirectory=, PIDFile=, EnvironmentFile=, ExecStartPost=, ExecStop=, possible others.

I'm sorry to say that this is MY project on OBS, and I'm adding anything I think is useful.

Are you packging /var/lib/fah-client directory?

Code: Select all

%attr (0750, %_name, %_name) /var/lib/%{_name}

Missing "%dir" here?

The line works as intended. The semantic of "%dir" isn't need here.

Also Wants=network-online.target is a big hammer we should avoid. Joseph made some changes to make the client more robust in case of missing network at startup. It should not require this anymore. syslog.target does not exist for more than decade. remote-fs.target is not needed...

All services on openSUSE depending on network connectivity use "network-online.target". This is exactly how I want it. Booting my desktop has absolute priority, whereas I don't care if fah-client comes 1 or 10 seconds later.

AMD users had to replace "libOpenCL.so.1" in the core directory to avoid a crash on openSUSE. This step can now be skipped by installing the latest rpm and adding the line

Code: Select all

FAHCLIENT_OPTIONS="--lib-path=/usr/lib64"

to "/etc/sysconfig/fah-client". This line will already be present for new installations.

Background: fah-client prepends the path of the core directory to the library search path (LD_LIBRARY_PATH). The option "--lib-path" in turn prepends the argument (e.g. /usr/lib64) to the library search path. This way the system libraries are preferred over the libraries shipped with the core.

Please compile from source instead. The generated RPM should work on openSUSE.

Code: Select all

sudo zypper -n in git scons gcc-c++ libopenssl-devel zlib-devel libbz2-devel systemd-devel rpm-build systemd-rpm-macros

git clone https://github.com/cauldrondevelopmentllc/cbang
git clone https://github.com/foldingathome/fah-client-bastet

export CBANG_HOME=$PWD/cbang
scons -C cbang
scons -C fah-client-bastet
scons -C fah-client-bastet package

Install double-clicking on the RPM file. GNOME Software or similar will take care of it. Or use the terminal:

Code: Select all

sudo zypper in ./fah-client-bastet/fah_client-<version>-1.x86_64.rpm

Ignore ("i") when zypper complains the package is not signed.

Hello i made a tutorial for fah-client-bastet based on your statements see viewtopic.php?t=42550
It works well.
But what are the statements for the stable fah-client 8.4.9 ?

Thanks

Dunno.
Messaged Marcos for help.

You built cbang first, right?

[promeneur]

You built cbang first, right?

I followed the statements

export CBANG_HOME=$PWD/cbang
scons -C cbang
scons -C fah-client-bastet

[calxalot]

Please try

Code: Select all

scons -C cbang test

You may need to install python module six for the test.

[promeneur]

Please try

scons -C cbang test

there are many python311 modules in openSUSE repo. What is the package name ?

I don't know.
I just use

pip3 install six
