powerpc64 11.0-CURRENT portmaster lang/clang36 gets another error: llvm-build: error: '::sscanf' has not been declared

[Mark Millard]

Basic context (more context details listed later):

# freebsd-version -ku; uname -ap
11.0-CURRENT
11.0-CURRENT
FreeBSD FBSDG5C0 11.0-CURRENT FreeBSD 11.0-CURRENT #0 r279514M: Wed Mar 11 19:23:14 PDT 2015     root at FBSDG4C0:/usr/obj/powerpc.powerpc64/usr/srcC/sys/GENERIC64vtsc-NODEBUG  powerpc powerpc64


The problem:

portmaster -tDK --no-confirm lang/clang36 is how I started the build.

The error reported was for in MSVCToolChain.cpp's member function:

bool clang::driver::toolchains::getWindowsSDKDir(std::__cxx1:string&,int&, int&) const

The report was:

MSVCToolChain.cpp:25:5: error: '::sscanf' has not been declared
::sscanf(sdkVersion.c_str(), "v%d.%d", &major, &minor);


I'd be surprised if 11.0-CURRENT vs. 10.1-STABLE matters. And it not being likely to be powerpc64 specific would be my guess. May be that it bootstrapped via gcc5? I've not yet tried from a powerpc (non-64) FreeBSD build.

It used gcc5 to bootstrap as there was no clang present and that is the only gcc port installed:
