[Coco] Microware C Compiler -- issues finding library files

Thu Aug 13 22:49:38 EDT 2015

Salvador, you are correct. From what I understand, the CocoFPGA runs appr. at 25mhz, so C compiling would be signifigantly faster as would assembly, though assembly doesn't have 1/10th the overhead of the C compiler (2 passes vs abo 6).

Bill, your biggest advice is worth gold! It is these small details that make or
break a project and the motivation behind.

>From what I can conclude from
reading threads posted here I would assume that using an FPGA CoCo3 with OS/9
would also be a much faster alternative for compiling C. Would that be a correct
conclusion? Has anyone done this and care to comment?
:-)

Microware C Compiler -- issues finding library files

Chris, the original
Microware C compiler is "hard coded" internally to look on
"/d1/defs" &
"/d1/lib" for it's defs & libraries. As they are, the compiler disk
should be in
"d0" and the library disk in "d1".
You can use "ded" to change this
as it's
present in "cc1" and "c.prep". There is an article in the 1989 Oct
Rainbow (p82)
about this; "What you should know about your C
compiler"

Alternately, you can
download the "cc.dsk" disk image of the C
compiler from the Nitros9 repo which
(I believe) already has those fixes and are
coded for "/dd/defs" & "/dd/lib". Of
course, you need to have the "/dd"
descriptor in your boot.

Also, you can
specify the library dir in the c.link
cmd line:
c.link -o=/dd/cmds/module xxx
xxx xxx -l=/dx/lib/clib.l

If you go
beyond just using the cmd line to compile
and use "makefiles", there are many
options to solve this. And ultimately, using
a ramdisk will make the compiler
faster (Coco 3, OS9 L2).

Personally, I prefer
a custom C system using several
"updated" or custom C tools. I also use NitrOS9
and Drivewire4.

The biggest
advise I can give is to use the Vcc Coco3 emulator
for C compiling as you can
overclock the CPU and compiling C programs takes only
seconds. Once compiled,
you can move your files to you Coco for testing. The
Coco (1, 2, or 3, even
6309) is slow as molassass in January when it comes to
compiling C code.
I have
a project that has over 125 C sources. It takes the
Coco most of the day to
compile. Vcc at 72mhz will compile it in a few seconds
(less than a minute) and
you still stay within the Coco and OS9 enviroment.

Microware C Compiler -- issues finding library

Gene,

I have the 1983
Microware C Compiler, version 1.0, cat number
26-3038
distributed by Radio
Shack.  Comes on 2 floppies: one has the compiler,
the
other has the
libraries.

Thank you!

Chris

Generally, those options are
set
in the
compilers driver script.  You 
didn't say which one, and there
are
several
variations extant.

Cheers, Gene Heskett

OS-9
scenario —
compiler (cc1) in /d1/cmds, LIB and DEFS (including stdio.h) on
/d0. 
Execution
directory set to /d1/cmds.  For the life of me, I can’t figure
out how
to get
the compiler to look on /d0 for LIB and DEFS — and I can’t put
everything
on /d1
due to space.  Is there a way in OS-9 to pin one of the drives
as the
“default
drive”, such that the compiler will look there vs. on the same
drive as
the
current execution directory?  When I get to the linker, for
example, I get
a
cannot-find error on “/d1/lib/cstart.r” — when, of course,
cstart.r is
sitting
in /d0/lib.
