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

[Mark Millard]

I tried "portmaster -tDK --no-confirm lang/clang36" on a powerpc (non-64):

$ freebsd-version -ku ; uname -ap
11.0-CURRENT
11.0-CURRENT
FreeBSD FBSDG4C0 11.0-CURRENT FreeBSD 11.0-CURRENT #0 r279514M: Mon Mar  9 22:24:27 PDT 2015     root at FBSDG4S0:/usr/obj/usr/srcC/sys/GENERICvtsc-NODEBUG  powerpc powerpc

Again it used gcc5 to bootstrap, my having installed gcc5 recently, no other non-built-in-world compilers ever having been installed before. No clang of any kind to start with. Just gcc 4.2.1. No changes to lang/clang36. Just:

portmaster -tDK --no-confirm lang/clang36

Again it had the same MSVCToolChain.cpp problem:

llvm[4]: Compiling MSVCToolChain.cpp for Release build
MSVCToolChain.cpp: In member function 'bool clang::driver::toolchains::MSVCToolChain::getWindowsSDKDir(std::__cxx11::string&, int&, int&) const':
MSVCToolChain.cpp:215:5: error: '::sscanf' has not been declared
     ::sscanf(sdkVersion.c_str(), "v%d.%d", &major, &minor);
     ^

Like before when I had installed gcc5 it had no troubles installing and I made no changes.


I have another build test running where only built-in-world compilers existed (gcc 4.2.1 and clang 3.4.1). For this context "portmaster -tDK --no-confirm lang/clang36" initiated installing lang/gcc (i.e., 4.8.4 at this point) in order to provide itself with a compiler to bootstrap with. We will see how that one does. It takes longer since 2 compilers are being installed. (I started this one first but it is not done yet.)

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:
