This archive contains miscellaneous tools from the GNU project, ported
to the Atari ST.
Please read the file COPYING, or look in the sources, for a
description of your rights and responsibilities as a user of GNU
software.
These files don't need to live anyplace in relation to the other GNU
stuff.
There are a bunch of things here; MAKE does the obvious thing with
makefiles, although this make seems to have features out the wazoom
compared to some other ones I've seen. LD is the linker. NM dumps
object files. Size and strip do something else with obj files, but I
don't know what. I haven't needed them so I haven't ported them, but I
included them anyway, as they came with the other stuff.
You'll likely have to use this one when building GNU stuff, or at
least the runtime libraries, as this make understands how to remake
individual elements of OLB files. The makefile that comes with the
libraries is set up with that in mind.
Both MAKE and LD have been fairly well hacked to run on the ST. All
changes are conditionalized with #ifdef atarist.
MAKE: Most of the changes here have to do with parsing pathnames
correctly. I also had to basically rip out the section that actually
interprets command lines. This MAKE knows how to ask Gulam to execute
commands for it, but since that part of Gulam is so buggy, odds are
about 2 to 1 you'll crash on the way back out of Gulam. This is
definitely Gulam's bug, but there's no fix in sight for it, so I've
had to kludge around it. To that end, when make decides it wants to
execute a command line, it parses out the command name, and looks for
an env var with that name. If it finds one, it assumes that's the name
of an image to spawn, and will just spawn that with the obvious
argstring. If it doesn't find it, it'll look for a program called
that name in the current directory. Failing that, it will finally ask
Gulam to execute the command. Sometimes it even works!
Finally, you should be careful about case in the names of things in
your makefiles. I tried real hard to make this thing be
case-insensitive, but it's pretty hopeless. You best bet is just
leave everything in lower case.
LD: This isn't really much changed, except in three areas, but they're
biggies. First, the header format it writes now are suitable for
Ataris. This is in contrast to the boject file format, which is still
defined by the Eunuchs-ish GNU-OUT.H. (I don't know who ever thought
they were supposed to be the same anyway; they're used for completely
different purposes...)
Second, the symbol-table writing stuff was completely replaced by
a frob that tries to write Atari format symbol tables. Since I can't
find anything that reads them, that's probably pointless, and I know
it's broken in at least one way.
Finally, the relocation info writing stuff has been replaced by
something that writes Atari format reloc info.
That's probably about all that's interesting. As usual, bugs and
question to me. Good luck!
