Error building latest on Mandriva 2010.2

I was able to update and build the latest on Fedora 17 but when I try on Mandriva 2010.2 I get:

make[1]: Entering directory `/home/mdeldiener/dev/clang/build/lib/Support'
llvm[1]: Compiling Signals.cpp for Debug+Asserts build

Any ideas where cxxabi.h is supposed to be on Mandriva ?

/usr/lib/gcc/x86_64-mandriva-linux-gnu/4.4.3/include

Alternatively, you can use cxxabi.h from libcxxrt

I see it there buit how do I discover why the build process for clang is not finding it ?

finding it ?

Pass the -v flag to the compiler. It will print the list of include
directories it's checking.
