[opensuse-packaging] Bug or mystique with set_version
by Konstantin Voinov 08 Apr '20

08 Apr '20

Hi, I've made a package which is fine with rpmbuild -bb at least. But when I try to run "osc build" locally or in OBS the "Version:" string in .spec is changing to "512x512.png" instead of "v1.10.0+git30.3277b64" for example: https://build.opensuse.org/package/show/home:kill_it/geonkick Maybe I missed something obvious, but where? -- To unsubscribe, e-mail: opensuse-packaging+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-packaging+owner(a)opensuse.org

[opensuse-packaging] Applying a fuzz to a patch

Hi, How can I apply a --fuzz=2 to a %patch0 -p1 command in a specfile? (adding the parameter does obviously not work....) Thx Axel -- To unsubscribe, e-mail: opensuse-packaging+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-packaging+owner(a)opensuse.org

"" In a single translation unit, the compiler is free to inline some instances of a function, and keep some invocations as function calls, correct? So what contradicts keeping exactly *one* definition (in this case in binarystoragebuffer.cpp) with external linkage? This does not contradict "not be defined in the other source files". There is exactly one instance of the symbol. Kind regards, Stefan -- Stefan Brüns / Bergstraße 21 / 52062 Aachen home: +49 241 53809034 mobile: +49 151 50412019

A compiler works on > CU-level (without LTO). Because the header file does not have a definition, just the the declaration? The declaration has no "inline", so the compiler can and must assume it has the only definition, and it must emit a global symbol. It is the same as if the definition had no "inline" keyword. The compiler should mostly behave if neither declaration nor definition had the "inline" keyword, just taking it as a hint to inline in the current CU. If the other CUs had a definition, this would be a violation of the ODR. But this is always the case, no matter if inline or not.

[opensuse-packaging] bring back removed package
by Jason Craig 02 Apr '20

02 Apr '20

What's the method to bring back a package that was removed from factory but still has a devel package (i.e. that package is broken because of the bad link)? Re-create it anew, or is there some way to bring it back from factory? thanks, -- Jason Craig -- To unsubscribe, e-mail: opensuse-packaging+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-packaging+owner(a)opensuse.org
