Some generic problems you might encounter (for other machine-specific
problems, see MACHINES):
* Question: I know all about slow starting TeX :-).
How do I organize the directory scheme to avoid the slowness, while at
the same time enjoying a structured inputs directory?
The answer has been moved to the Kpathsea manual, in the section
`Subdirectory problems', so I don't have to keep it in two places.
Please read that.
* If you run out of memory space making plain.fmt, because memsize=3000,
somehow the trip constants have persisted. make clean-triptrap and
make again.
* wchar_t is the source of endless problems compiling x11[-Xt].c. See
xdvi.h in my xdvik distribution for all the details; I'm not going to
repeat all that here. You can try defining NO_FOIL_X_WCHAR_T.
* For DOS, you may have to change the definitions of WORDS_BIGENDIAN and
DOS in lib/c-auto.h. Here are some additional notes:
From: Richard Mansfield <melvin@math.psu.edu>
Date: Mon, 9 Nov 92 14:24:10 -0500
Make the changes in site.h. I don't know if I got the default
directories to work. TEXPOOL seemed to work fine (using /), but I had trouble
with TEXINPUTS. After minimal attempts to get it right, I punted
and decided to use environmental variables. In the variables I use
\ and ; as a separator as in DOS. Thinking about in some more as I write
this, my troubles could have been caused by not correctly reading tex.pool
although I don't know.
My method for getting the source files was to do
make TeX > tex.log
on the SUN and then editing tex.log to become tex.bat. I then carried
the .c and .h files home on a floppy and compiled them at home.
DOS gcc does have yacc and bison, but I did not use them.
If you want to see my exact set up. ftp to ftp.math.psu.edu,
look in directory pub/melvin/pctex and get the files read.me
and tex.zip.
* GNU sed 1.06 cannot handle the sed script in mf/convert; neither can
1.07. 1.08 and later fix it.
* Likewise, sed on a 386/bsd machine can't handle it, according to
bsd@yrloc.ipsa.reuter.com.
* GNU Make 3.57 does not pass arguments to shell scripts (like convert),
under system V. 3.56 does not have this problem, and neither do later
versions.
* On an i386 machine, GNU C 1.36 does not compile tex5.c correctly when
making a 32-bit TeX. 1.37 fixes this bug.
* On the AT&T 3b2, under System V release 3.2, cc thinks that
eject_penalty (which is -1000, defined at line 3216), is a very large
positive number. oc@vmp.com is developing a port for the 3b2; he has
contributed some (incomplete) patches; they are below.
* On a Sun 3 running 3.x, cc cannot compile mf2.c or mf4.c, because the
preprocessor puts a # directive at the end of line 1811 (or
thereabouts), instead of at the beginning. You have to manually move
it.
* On a Sun 386i running 4.0.1, cc cannot compile Metafont with -O, because it
can't compile x = x + y correctly. Don't use -O, or don't use cc.
(From morgan@ics.uci.edu.)
* Make loses heavily if you are using a networked filesystem, and the
server and the local machine have different times. You might have
this problem if `initex' gets made twice, for instance.
* On a 386 machine running 386/ix, cc cannot compile itex.c, according
to Reiner Petersen <reiner@db0tui62.bitnet>. Here is an ed script to
get around the problem (alternatively, you can get gcc, and compile with
that):
:
# Reiner Petersen (reiner@coma.uucp)
# Technical University of Berlin
#
ed - $1 << end-of-edscript
!echo change:
/ register integer for_end; i = 1 ; for_end = 31 ; if ( i <= for_end) do
+1,.+2p
-2,.c
register integer for_end;
register char j; /* 386/ix cc bug workaround rp */
i = 1 ;
for_end = 31 ;
if ( i <= for_end) do
j = i;
xchr [ j ] = chr ( i ) ;
while ( i++ < for_end ) ;
.
!echo to:
-8,.p
w $1
end-of-edscript
If you want, you can put this into the pipeline in ./tex/convert.
* undump doesn't work under 386/ix. Here is a diff to undump.SYS_V.c to
fix this, again contributed by reiner:

When compiling for an Atari ST, some of Metafont's constants have to be
decreased (even beyond small.sed), according to
ridderbusch.pad@nixdorf.com.
