Can somebody help me to apply a patch only if kernel >= 4.5 in a spec-File?
I do not know, how to do this, get only errors…
In my spec-File:
%prep
%setup -q
if ((uname -r | awk -F. '{print $1"."$2}') >= 4.5);
then %patch0 -p1
fi
Error:
52s] + /usr/bin/chmod -Rf a+rX,u+w,g-w,o-w .

52s] error: Bad exit status from /var/tmp/rpm-tmp.gEvT9Z (%prep)
52s]
%if %version >= 4.5
%patch235 -p1
%endif
That results in: (same in kernel 4.5)

Right, sorry. Of course, it is not simple numeral so comparison fails. You probably can beef up something using Lua (see http://www.rpm.org/wiki/PackagerDocs/RpmLua) but I ask myself why you need it? Package version is not something variable. It makes sense to be conditional depending on architecture or distribution version, because you use the same spec file everywhere. But you do not use the same spec file for different versions - your spec is either for version < 4.5 or for version >= 4.5. So as soon as you bump spec file version you add patch.
Please explain what you are trying to achieve using this condition?
Hi
Normally I would rebase the patch to use IFDEF statements defining the kernel version around the code… I may be an option depending on what the OP is patching.
I want to build the original r8168 from Realtek, in Kernel 4.5 I get an error:
82s] /home/abuild/rpmbuild/BUILD/r8168-8.041.01/obj/default/r8168_n.c:4212:30: error: 'NETIF_F_ALL_CSUM' undeclared (first use in this function)
82s] features &= ~NETIF_F_ALL_CSUM;
A kernel < 4.5 will build.
So I made a patch:

Now it builds without any error, but only for Kernel 4.5.
In any kernel < 4.5 I get:

PS
I know, the r8169 is in the Kernel…

Hi
Add statement around it, something like or vis-versa for versions and
statement;
#if (LINUX_VERSION_CODE >= KERNEL_VERSION(4,5,0))
features &= ~NETIF_F_CSUM_MASK;
#else
features &= ~NETIF_F_ALL_CSUM;
#endif
Then rebase your patch.

As already mentioned you should check kernel version in patch.
#if LINUX_VERSION_CODE < KERNEL_VERSION(4,5,0)
features &= ~NETIF_F_ALL_CSUM;
#else
features &= ~NETIF_F_CSUM_MASK;
#endif
Thanks, I have done it in the src, here is the patch:

Now it builds without any error, but if it works I can check only next week…
So thanks to arvidjaar and malcolmlewis
Hi
You should advise the folks you downloaded it from and send them the patch…
