- Enable the shared library build on darwin by default to match other
platforms.
- Fix the dylib file's name in the store
- Symlink a versioned name as some tooling expects this.
Make Obj public in llvm's IntrusiveRefCntPtr
This fixesNixOs/nixpkgs#15974
It's not a nice fix, as it's really clang's problem. The proper fix
should modify clang's usage of IntrusiveRefCntPtr.
The hashes for libc++ and libc++abi were wrong.
There was also an incompatibility with nixpkgs on darwin which is now
weakly worked around: the "os_trace" macro changed definition in the OS
X development SDK since version 10.9 as used by nixpkgs. LLVM 3.8 uses
the new version, which I am temporarily replacing with a printf on
darwin as it is only used in one minor location.
vcunat's review:
- let's not switch the default versions of llvm* for now
- the only changes I see is adding python to clang's buildInputs
and using the big so-file as discussed in #12759
(BUILD_SHARED_LIBS -> LLVM_LINK_LLVM_DYLIB)
- in future it will be nice to split libLLVM into a separate output
The most complex problems were from dealing with switches reverted in
the meantime (gcc5, gmp6, ncurses6).
It's likely that darwin is (still) broken nontrivially.
Package changes from 3.6:
- CMake exports patch no longer necessary
- Cosmetic purity patch fix
- Build libc++ with private libc++abi headers visible from sources
- Work around bugs in lldb's configure scripts
This corrects linkage failures arising from missing -lc++abi and
resolves "unused argument" warnings arising due to -stdlib=libc++
serving no purpose when search paths are being supplied explicitly.
Also use recurseIntoAttrs only on the default version (instead of only on 3.4).
The "self" variants (stil) don't build and they're inconsistent
versions. /cc @shlevy (fea2266290).
