The problem here is that it is not just a library. libkatze itself is a .a static library which is merged into midori and this is fine. But it is also merged into a few add-ons which are .so and that's where you need the -fPIC because now the static library becomes suddenly a shared library as well. Adding -fPIC to the whole build process is a bad idea please don't do that. My initial proposals where: - make libkatze a .so. midori and extension can link against that. => that one was NAKed by upstream because a new lib is not what he had in mind if I remember correctly. - add fPIC unconditional and use it while build ing libkatze (not always). => was NAKed by upstream because it is so much slower on x86_32. Now, we need special care for parisc and mips afaik. Other arches may follow once the offset are big enough. Maybe we could go the other way around and add -fPIC to libkatze unless it is x86_32?
