Re: Building PCC for "tools" is broken (missing symbol __USE)- PCC bug or NetBSD source tree error?

["William D. Jones" <thor0505%comcast.net@localhost>]

I should probably split this email up into two issues, but since they are 
both PCC-related...

Fair enough. I need a vacation at some point.

Well, it's doing alright so far. Just would be nice to have a choice in 
compiler for NetBSD 7.0. I'll just apply patches to my tree directly and not 
mess with the dev scripts.

I have two things to report:
1. The problem with __restrict has been fixed thanks to Ragge's patch. 
However, there are now a two other issues that happen later in the build. 
See the email I sent at August 10th, 1:17 AM EDT. In summary: when building 
a kernel, the preprocessor complains about an invalid command line for a 
specific target. I believe the preprocessor may be buggy, as I demonstrate a 
sample command line with the same "issue" that the preprocessor accepts with 
out complaint.
Additionally, when building userland, PCC attempts to build a C++ tool 
(libatfc++). Of course, PCC being a C compiler, PCC chokes on it. I'll 
probably just modify the relevant Makefile to have PCC skip it, but before I 
go ahead and do that- is libatfc++ essential for a functioning userland or 
POSIX compliance?

2. When attempting to build userland with the following mk.conf, I receive 
an error regarding a missing libgcc:
COPTS=-Os -Wno-error=uninitialized -Wno-error=maybe-uninitialized #This is 
irrelevant, more than likely
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'll be on standby and attempting to make changes of my own to get PCC to 
compile userland... it seems that the kernel will have to wait for now.
