[opensuse-factory] Can't take care of peazip anymore
It can't be built with Qt and it has a few other problems upstream won't take care of and that I can't fix due to significant rustiness in all things pascal/delphi. Anyone willing to adopt it? -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

Well, my program doesn't need/use it. It appears to be a parameter (-pie) passed to the linker: -pie --pic-executable Create a position independent executable. This is currently only supported on ELF platforms. Position independent executables are similar to shared libraries in that they are relocated by the dynamic linker to the virtual address the OS chooses for them (which can vary between invocations). Like normal dynamically linked executables they can be executed and symbols defined in the executable cannot be overridden by shared libraries. I don't see how that can be related to not finding the graphics unit. Anyway, I activate it in my program: ...

Luigi wants to build peazip in PIE mode, and has a patch in that package to make it so. But PIE only works if _all_ dependencies are PIC/PIE too. fpc is PIE-enabled. lazarus isn't. That breaks the chain towards peazip which aspires PIE. Having PIE is a SUSE policy, similar to LTO.

Ok, I understand the issue. But you can not force upstream to change to use PIE. My guess is that you would have to rebuild the entire RTL stack. I tried/did once, long ago, then refrained, not worth the effort. Basically, instead of giving the location of the units to link, you give the location of their sources, so that they are built new, local to the current project, using the project options. -- Cheers / Saludos, Carlos E.

The RTL (of any language) is supposed to be PIC already, otherwise we would have had problems with shared libraries a long time ago. Anyway, turns out, the problem was identified already and a submission was made to OBS (only this late event sent a notification my way). https://bugzilla.opensuse.org/show_bug.cgi?id=1176706 All is good.

RTL is the wrong name, sorry, but I forget the right one. The RTL comes with the compiler and you say they are compliant already. There is a bunch of units that comes with Lazarus... ah, the LCL (Lazarus component library) which maybe is not compliant.

Thank you. I'm sorry I can not contribute, I know nothing about the OBS, and I tried. Besides, my expertise is with the old Borland Pascal up to version 7, not with Lazarus / Free Pascal. -- Cheers / Saludos, Carlos E. R. (from 15.1 x86_64 at Telcontar)
