Bug ID: 15877
Summary: configure complains that cxxabi.h is present but
cannot be compiled
Product: Build scripts
Version: trunk
Hardware: Macintosh
OS: MacOS X
Status: NEW
Severity: normal
Priority: P
Component: autoconf
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
I was in a build directory that's a sibling of the llvm repository directory,
and typed
../llvm/configure --prefix=/opt --enable-optimized
Among lots of output was this:
checking cxxabi.h usability... no
checking cxxabi.h presence... yes
configure: WARNING: cxxabi.h: present but cannot be compiled
configure: WARNING: cxxabi.h: check for missing prerequisite headers?
configure: WARNING: cxxabi.h: see the Autoconf documentation
configure: WARNING: cxxabi.h: section "Present But Cannot Be Compiled"
configure: WARNING: cxxabi.h: proceeding with the preprocessor's result
configure: WARNING: cxxabi.h: in the future, the compiler will take precedence
configure: WARNING: ## ------------------------------------ ##
configure: WARNING: ## Report this to http://llvm.org/bugs/ ##
configure: WARNING: ## ------------------------------------ ##
checking for cxxabi.h... yes
I don't know what it's about, but it says to report it.
llvm svn revision 180835. Mac OS X 10.7.5. Xcode 4.6.2.
