In the case where a weakly declared symbol has no definition, it should just resolved to be NULL instead of failing to load at all. GCC 11 builds of libroot.so wind up having one weak symbol declaration that is unresolved at runtime, to __cxa_pure_virtual, which seems to be provided by some object in libsupc++.a that ld does not pull in automatically (and has to be forced at present.) This change also amends symbol patcher behavior: it is now possible for the symbol patcher to indicate symbols should be hidden by changing the passed-in type to 0, instead. (Otherwise, weak symbols would always get a value of NULL instead of being able to be hidden.) Fixes #8288.

Haiku
Homepage | Mailing Lists | IRC Channels | Issue Tracker | API docs
Haiku is an open-source operating system that specifically targets personal computing. Inspired by the BeOS, Haiku is fast, simple to use, easy to learn and yet very powerful.
Goals
- Sensible defaults with minimal configuration required.
- Clean, clear, concise code.
- Unified desktop environment.
Trying Haiku
Haiku provides pre-built nightly images and release images. Haiku is compatible with a large variety of hardware, but in case you don't want to "take the plunge" and install Haiku on bare metal, you can install it on a virtual machine (VM) instead. If you've never used a VM before, you can follow one of the "Emulating Haiku" guides.
Compiling Haiku
See ReadMe.Compiling.
Contributing
Haiku is a meritocratic open source project with a large variety of tasks. Even if you can't write code, you can still help! Haiku needs designers, (technical) writers, translators, testers... Get involved and help out!
