powerpc64 11.0-CURRENT portmaster lang/clang36 gets error: llvm-build: error: invalid native target: 'powerpc64' (not in project)

[Mark Millard]

patch-utils_llvm-build_llvmbuild_main.py is missing a powerpc64 entry, such as illustrated below.

The 2 powerpc (non-64) build attempts for clang 3.6 did not get this problem.

So this specific problem is powerpc64 specific.

Bootstrapping powerpc (non-64) clang 3.6 via gcc 4.8.4 (the current lang/gcc) works fine. (In absence of any c++ port lang/clang36 automatically installed lang/gcc (currently gcc 4.8.4) in order to bootstrap itself.)

Bootstrapping powerpc (non-64) clang 3.6 via gcc5 (by having lang/gcc5 already installed first) still reports an error for not declaring ::sscanf, just like powerpc64 based on gcc5 for bootstrapping did.

(This might be llvm/clang making use of only <cstdio> where an include of <stdio.h> would be required to be involved in order to guarantee the :: (global) declaration/definition. The way the C++ standard (all vintages) is written gcc 4.8.4 and gcc5 could be this different and both be valid/conforming.)

The problem:

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

The error report was after it reported entering the directory:

/usr/obj/portswork/usr/ports/lang/clang36/work/llvm-3.6.0.src/tools/clang/lib/Driver/

The report was:

llvm-build: error: invalid native target: 'powerpc64' (not in project)


I'd be surprised if 11.0-CURRENT vs. 10.1-STABLE matters. But powerpc64 likely does. I've not yet tried from a powerpc (non-64) FreeBSD build.

I'll note that with top -PaSCHopid I watched it compile the PowerPc code generator software: it shoudl be able to handle PowerPCs fine.

My guess is a conversion of naming conventions is required someplace:

FreeBSD using powerpc64 vs. clang using ppc64. (Big endian context.)

This likely would matter for little endian naming as well (ppc64le on the clang end of things I expect).

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