Trouble with spec file / paths

English Open Build Service (OBS)
1

Hi, I need a kick into my backside. I am currently trying to build a package for mjpg-streamer. I decided to have the following layout:

  • The executable goes into /usr/bin

  • Some modules required by the executable should end up in /usr/share/mjpg-streamer/lib

  • A couple of html scripts used by the executable go into /usr/share/mjpg-streamer/www to avoid conflicts with apache.

The application compiles with build but then throws errors during the checks. This is the spec file:

# norootforbuild

%description
MJPG-streamer takes JPGs from Linux-UVC compatible webcams, filesystem or
other input plugins and streams them as M-JPEG via HTTP to webbrowsers, VLC
and other software. It is the successor of uvc-streamer, a Linux-UVC
streaming application with Pan/Tilt.

The Makefile of this application installs like this:

What am I doing wrong?

Hi
Your installing the files in mjpg-streamer-2.0 but I’m guessing your
%files section is pointing to mjpg_streamer (See no -2.0).

Your installing the files in mjpg-streamer-2.0 but I’m guessing your
%files section is pointing to mjpg_streamer (See no -2.0).

I tried to change this to:

%files
%defattr(-,root,root)
%doc README CHANGELOG LICENSE start.sh
%{_bindir}/mjpg_streamer
%{_datadir}/%{name}-%{version}/lib/input_control.so
.....

but this did not help. So I reverted the change back. When I go and have a look I see:

cd /var/tmp/mjpg-streamer-2.0
host:/var/tmp/mjpg-streamer-2.0 # find . -name input_control.so
./var/tmp/mjpg-streamer-2.0/usr/share/mjpg_streamer/lib/input_control.so
./usr/src/packages/BUILD/mjpg-streamer-2.0/input_control.so
./usr/src/packages/BUILD/mjpg-streamer-2.0/plugins/input_control/input_control.so

but it says:

RPM build errors:
    File not found: /var/tmp/mjpg-streamer-2.0/usr/share/mjpg-streamer/lib/input_control.so

I have the strange feeling that I’m overlooking something obvious or have some deep misconception.

Hi
Can you provide a link to your OBS project?

Yes, shortly. For the time I was trying to get it working locally with the build utility, but I will upload it that you can see the whole picture.

6

In general:

NEVER install architecture dependent files (I would bet those so-files are) into /usr/share/whatever, rpmlint will cry out loud about this, even if you manage to fix the above problem.

7

The link is:

I hear your voice. You would suggest to put them into the big basket at /usr/lib ???

9

No!

Not /usr/lib, but %{_libdir}, which is not the same.

Use macros as often as possible, this will save you a lot of work and prevent lots of trouble.

10

Smile; on my machine it’s the same. But of course I use the makro. Effect of this change is: no more error message regarding the *.so modules.

However, the html files are system independent and these still don’t install.

Hi
In you patch, your installing the binary as bin add a trailing / You
have it right for the lib files (as Akoellh pointed out but the wronng
location). Also don’t for get to include a ldconfig for the libraries;

Hi again, and thank you for this help.

I added the trailing slash and did put the lib files at %{_libdir}. They install ok now (still wonder why they didn’t at the wrong place before). This suggests to me that I have to change something in the %files section as well to make the www stuff install.

BTW these *.so files are loaded by the executable at runtime with the dlopen() function and found at a location set in the LD_LIBRARY_PATH environment variable. This should work even without ldconfig.

13

If %makeinstall does not do the job for you, then install them “by hand” in your %install section or use the %doc-macro if applicable.

Hi
Your libdir is still not correct for 64bit builds, the www files are
in mjpg_streamer whilst %{name} is mjpg-streamer

Bingo! The subtle difference between an underscore and a hyphen. I see some light coming through the fog. I fix this and report back.

16

Better put them into %{__libdir}/<package>/
Packaging/Shared Libraries - openSUSE

17

Hi
Put the so files under the rpm name, also your files section only needs
to be something like;


%files
%defattr(-,root,root)
%doc README CHANGELOG LICENSE start.sh
%{_bindir}/mjpg_streamer
%{_libdir}/%{name}/*.so
%{_datadir}/mjpg_streamer/www/*

Hi again, saying thank you to all of you.

I have learnt a lot within a short time and the package builds successful now for 11.0 / 11.1 and 11.2. It still needs quite a bit of cleaning up and being documented the SUSE way. I will do this within the next few days, hoping it will be useful for the community.

Going to bed now, it’s half past midnight here.
