Recent changes have been trying to make things like =
powerpc64-xtoolchain-gcc/powerpc64-gcc work better for =
buildworld/buildkernel.
I happen to do this on a powerpc64 context so the "cross build" is =
actually self-hosted. No gcc 4.2.1 is present and clang 3.8.0 and before =
have code generation problems for powerpc64 and powerpc so I avoid it =
for system builds, including for stage 3. (Also, clang for powerpc64 =
does not support building libstand: no soft-float support.)
As of my last test (-r297465) buildworld's stage 3 failed from implicit =
use of /usr/local/include materials unless I renamed various files =
there. In part this is because of my using gcc49 tools for CC and for =
CXX while using the powerpc64-gcc tools only for XCC and XCXX.
Is there a standard or recommended way to configure things to avoid such =
issues? Should powerpc64-gcc use be forced for CC and CXX as well as XCC =
and XCXX?
Should there be xtoolchain usage notes about avoiding /usr/local/include =
name conflicts and/or about how to assign CC/CXX/XCC/XCXX?
As long as I use gcc49 tools for CC and CXX I still must do things like =
renaming files in /usr/local/include to avoid them interfering with =
system headers:
> # find /usr/local/include/ -name 'renamed*' -print
> /usr/local/include/renamed_dwarf.h
> /usr/local/include/atf-c/renamed_defs.h
> /usr/local/include/renamed_iconv.h
> /usr/local/include/renamed_libdwarf.h
> /usr/local/include/renamed_histedit.h
I use the likes of:
> # diff -rq /usr/include /usr/local/include | grep "^Files "
to find what to rename for the duration of the system builds.
An example of what happens without the renames is below but I first note =
the use of the name dwarf_errmsg in /usr/include vs. in =
/usr/local/include (shown after the .h file rename but the build was =
with the normal file name):
> # find /usr/include/ -exec grep dwarf_errmsg {} \; -print
> #define dwarf_errmsg(error) dwarf_errmsg_(&error)
> const char *dwarf_errmsg_(Dwarf_Error *);
> /usr/include/libdwarf.h
> # find /usr/local/include/ -exec grep dwarf_errmsg {} \; -print
> char* dwarf_errmsg(Dwarf_Error /*error*/);
> /usr/local/include/renamed_libdwarf.h
> #
So dwarf_errmsg is from /usr/local/include and dwarf_errmsg_ is from =
/usr/include .
The failure shows references to dwarf_errmsg instead of dwarf_errmsg_ =
--and dwarf_errmsg being undefined (dwarf_errno has similar issues):

[Note: I have been able to remove some of my local workarounds as things =
have been cleaned up recently. This area is just not one of them. =
Getting powerpc64-gcc installed on a powerpc64 environment is one of =
those things needing work arounds. amd64 building powerpc64-gcc has no =
such issues (true cross compiler context: TARGET_ARCH=3Dpowerpc64 not =
matching the host OS).]
