#16083: tests relying on <iostream> in Objective C++ are broken on Mojave builder ---------------------------------+-------------------------------------- Reporter: bgamari | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.6.3 Resolution: | Keywords: Operating System: MacOS X | Architecture: x86_64 (amd64) Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | ---------------------------------+-------------------------------------- Old description:

It appears that something has changed in the Darwin toolchain such that `<iostream>` is no longer found by default: {{{ cd "driver/recomp001/recomp001.run" && $MAKE -s --no-print-directory recomp001 Compile failed (exit code 1) errors were: warning: include path for stdlibc++ headers not found; pass '-std=libc++' on the command line to use the libc++ standard library instead [-Wstdlibcxx-not-found]

*** unexpected failure for objcpp-hi(normal) }}}

Marking as broken.
