Tiger: llvm-3.3 fails to build: stat64 and error: '_CS_DARWIN_USER_TEMP_DIR' was not declared in this scope

[ryandesign (Ryan Carsten Schmidt)]

llvm-3.3 doesn't build on Tiger PPC.

[ccarey@…]

Neither _CS_DARWIN_USER_TEMP_DIR nor _CS_DARWIN_USER_CACHE_DIR are defined in <unistd.h> in PPC Tiger. The simplest fix might be to change line 499 of lib/Support/PathV2.cpp from

#ifdef __APPLE__

to

#if defined(__APPLE__) && defined(_CS_DARWIN_USER_TEMP_DIR) && defined(_CS_DARWIN_USER_CACHE_DIR)

That change should allow PPC Tiger to use the non-Apple fallbacks in lines 520 through 544.

Even after fixing this, you'll run into #39761

I'll tackle this after moving the build over to cmake...

Even after fixing this, you'll run into #39761

After fixing this locally (and with #39761 now fixed generally), the next error to appear in PPC Tiger is due to clang’s common Sanitizer code presuming that struct stat64 is available on all platforms in projects/compiler-rt/lib/sanitizer_common/sanitizer_platform_limits_posix.cc. The AddressSanitizer is documented in sanitizer_mac.cc in the same directory as not supporting Leopard due to its lack of 64-bit inodes, so it will also not support Tiger. Whether ThreadSanitizer would support Tiger if the 32-bit stat()-family of calls were to be used there remains to be discovered.

If you have a patch, I'll take it, but if not, I'll be closing this as wontfix in the near future.

[jeremyhu (Jeremy Huddleston Sequoia)]

I want to obsolete llvm-3.2, so I'll need to work around this. Reopening.

[jeremyhu (Jeremy Huddleston Sequoia)]

llvm-3.4 should be fixed with r131782.

Leaving open to do llvm-3.3.

On PPC Tiger I have now a new failure:

Please file new tickets for new failures in the future.

[jeremyhu (Jeremy Huddleston Sequoia)]

r131792 for that one, but in the future, please do file new tickets.

[jeremyhu (Jeremy Huddleston Sequoia)]

From discussion I recall from other tickets, I believe this was fixed.
