Spec help

Been trying to update OBS-studio from 6.4 to the 8.3 release, however when building the rpms the main rpm always requires the dev packages to be installed to.

From what i've read

Code: Select all

BuildRequires:

means only needed when been built and

Code: Select all

Requires:

for what the package needs.

I am has me stuck to ne honest, also having the same issue with the new roccat rpms doing the same. Any pointers guys/gals?

Been trying to update OBS-studio from 6.4 to the 8.3 release, however when building the rpms the main rpm always requires the dev packages to be installed to.

That is usually a different issue and not related to Requires/BuildRequires at all. If that happens, usually that is because no proper libification was done.
That means, the normal library package should only contain the library, and a separate -devel package contains the development headers and a symlink to the library.

From what i've read

Code: Select all

BuildRequires:

means only needed when been built and

Code: Select all

Requires:

for what the package needs.

Exactly. FWIW, Requires: are usually only added when some binaries are needed on the target system
Dependencies on libraries, perl/python and ruby stuff and some more are automatically added by rpm itself as it will scan all files that are packaged in the rpm for dependencies.
See the macro %__find_requires and /usr/lib/rpm/mageia/find-requires for more on that.
This is also extensively covered in our packaging guidelines: https://wiki.mageia.org/en/Packaging_gu ... t_Requires
Feel free to drop me some lines if things are unclear and I'll explain


The spec you posted looks OK so far, except that you should use %cmake to not have to fiddle around later manually with /usr/lib64 and /usr/lib

For library packages, here's a skeleton spec, for your question regarding the dependencies on -dev packages pay attention to the %files list.

Well, still stuck. Not a clue what is causing it tbh.

I tried the %cmake but then the build fails on jannson needing 2.5 as it then fails to build the bundled version.

[doktor5000]

Hmmm, that sounds like a different issue. Usually with cmake it's good to go to the BUILD dir, and run ccmake .
to see which switches/options it accepts as you may need to adjust the paths to some libraries if it doesn't find them.

In this particular case you maybe need to adjust Jansson_LIB as it defaults to /bin/../lib64/libjansson.so which looks pretty weird.
But even that would not help unless you locally upgraded jansson to a version >= 2.5

-- Jansson >=2.5 not found, building bundled version

From a short try with the current version 0.9.1, manually running cmake . and make successfully builds obs-studio.
Maybe you should try that first.

[doktor5000]

Another approach would be to try a different source package for obs-studio, maybe the one from packman/opensuse:
http://packman.inode.at/suse/factory/Mu ... .1.src.rpm

Not having a problem using cmake as originally used. It's the dev deps that's got me stuck . Was looking at the suse build earlier . will give that a go later and see.

Cheers Dok.

Edit: Had a go with the suse build/src. Same issue .
