yacc dependency of aic7xxx driver

yacc dependency of aic7xxx driver

[Jörn Nettingsmeier]

hello justin !

i have just tried to install the latest 2.4.3pre3 kernel with your
driver.
it failed with yacc: file not found.
while i could install yacc, i have never had to use it before. i was
assuming that the newer bison could do the same thing (which is what
i have installed).
so far, the kernel has not relied on yacc, which is why i'd like to
ask you if it's possible to make it work with bison.

sorry if this has been dealt with before, but i didn't find anything
in the lkml archive.

regards,

jörn

please keep me cc:ed, i'm not on lkml. thanks.

The assembler makefile doesn't reference yacc, but instead relies
on gmake's built in rules to figure out how to generate a .c from
a .y.  I'm somewhat surprised that bison doesn't create a link to
yacc or that gmake doesn't try to look for bison.

Oh well.  We'll just have to be more careful in how future patches
are generated so that the dependency between the generated firmware
files and the firmware source only triggers if you are actually
performing firmware development.  Trying to build this simple
assmebler on everyone's systems is turning out to be just too
hard.

Yepp, gmake is kindof stupid in that respect - it does also not try
to use flex if there is no lex, etc...  I'd really vote for a BSDish
sys.mk.

What about simply removing the firmware source and assembler from the
kernel tree?  We have lots of firmware in the kernel tree for which
there isn't even firmware  avaible...

The few people that want to do firware development could download it
from your ftp site.

Of course it doesn't work. We've performed a software upgrade.

What, and not allow others to fix my bugs for me? :-)

Lots of people have embedded this driver just because it is completely
open source.  I'd like to have all distributions be "complete"
distributions.

alias yacc='bison -y'

If you don't have one of these, you don't have the tools necessary
to do kernel development.

	I presume the aicasm (or whatever) can do its meager DB needs
	by simpler ubiquitous things like  GDBM.   SleepyCat DBx is good,
	but in this case as serious overkill as e.g. using Oracle ;)
	(No, I didn't read the source of the aicasm.)

	There really should be some convenient way to compile the firmware
	from source when wanted, but the normal case should not be dependent
	of FIRMWARE SOURCE - the integer/byte array include file should
	be enough for normal users.

		$ (cd drivers/xx/yy; make aic7xxx.fw )

	What HOSTCC et.al. settings are needed, that I can't say,
	and that 'make' method doesn't get top-level definitions in...

	Simultaneously (as 'aic7xxx.fw' would not be the real filename),
	aic7xxx.o file's dependencies would contain the real firmware
	files so that "make bzImage" will recompile it correctly.

	When people like Justin are sending the driver update to Linus,
	they just need to be carefull at sending all relevant files/diffs.

	We are placing a lot of trust to these firmware makers to supply
	us working firmware, why not trust them to do it right so that
	compiling kernel won't need to generate firmware assembler program
	at first...

People keep saying stuff like this.  I think one of the best things
a developer can realize is that being lazy is often a good thing.  I
already was experience with using db, it took me about 5 minutes to
utilize it for this project when rolling my own would have taken
much longer, and it happens to be available on almost any platform
of interest (including windows which is used to host some of the RTOS
environments that also use this driver).  More importantly, it works...
so why fix it?

People who really want to assemble the firmware will install the required
packages.  We'll just ship precompiled firmware and make sure the dependencies
don't fire even if only a few of the files in the dependency chain are
updated.

Not having it in the kernel tree doesn't have to mean not having it in
the distributions.  If you are really concerned having iy in the kernel
tree it might also be a good idea to have it in scripts.

i might also be SuSE 7.1 related, since this was the first kernel i
compiled on the new distro.
but since the problem arose only with the new aic driver, i thought
it might be that you had a slightly different development
environment...?

anyway, robbert muller sent me the following simple workaround:


<quote>
Just create a shell script called yacc with the following content
-------------------
#!/bin/sh
bison --yacc $*
-------------------
i ran into the same problem with a school proiject here yesterday
</quote>

jörn

Why does nobody learn shell anymore?  (Just curious.)

  #!/bin/sh
  exec bison -y "$@"
