Re: Building PCC for "tools" is broken (missing symbol __USE)- PCC bug or NetBSD source tree error?
The error to which I refer to (cannot find -lgcc) also occurs now, even when
I set HAVE_PCC=1 while building libc... it seems that there is a depedency
problem that has crept into the NetBSD source tree the past few days,
because me receiving complaints about a missing libgcc when only building
the PCC tools only started in the 2 to 4 days.

MKPCC=yes
MKGCC=no
HAVE_GCC=4 #Define if MKGCC=no
#HAVE_PCC=1
Essentially, I want to use GCC to build a userland with PCC only for my
486
machine to save space and compiling time.I think this is a dependency
error
that the build system misses; it seems as if MKGCC isn't honored for
certain
Makefiles. Does anyone familiar with build.sh internals have any idea on
how
to fix this?
I rather suspect this is unknown territory, with half-grown features
lying in wait to trap the unwary.
In the beginning, PCC support started to be added in the style of the GCC
support, but I think this is not fully tested (since PCC cannot yet build
everything). Latterly, Joerg has been working on LLVM support and he has
added the AVAILABLE_COMPILER functionality, but there are still remnants
of the previous setup, and I am not sure if there is yet a final design
for providing a NetBSD release with a different compiler, though as far as
I know, LLVM/Clang should be capable enough (there are still some
UNSUPPORTED_COMPILER.clang instances in the GCC code)
