Hmm,
I've never tried to build the BSP using Cygwin, so I'm not too sure, but I have a question for you:

How long is the path that you've placed the BSP in? If its pretty long then some of the compiliation command lines may overflow the maximum length of what can be passed to a sub-process(yeah, its some unix-babble, but I gotta try to explain it).

Could you put the BSP in a top-level directory like "\LinuxBSP" and try again?

Also if you could, send me a trimmed down verison of the output that shows the first error? By trimmed, I'd like to see from the last make message that indicates "make[xxx]: Entering `/some/directory/in/the/BSP'", up to and including the first error where you see the "too many arguments". This will help me to try to discern what's going on...

the physical directory is C:\linuxbsp. However, it is seen by cigwin as /cygdrive/c/linuxbsp. Here is the last part of "make dep" where it aborts

Ok, it soulds like the ouptut from 'mkdepend' is too large due to the length of the path.

Could you execute the following:

$ /cygdrive/c/linuxbsp/linux-2.4.26
$ find /cygdrive/c/linuxbsp/linux-2.4.26/include/asm /cygdrive/c
/linuxbsp/linux-2.4.26/include/linux /cygdrive/c/linuxbsp/linux-2.4.26/include/s
csi /cygdrive/c/linuxbsp/linux-2.4.26/include/net /cygdrive/c/linuxbsp/linux-2.4
.26/include/math-emu \( -name SCCS -o -name .svn \) -prune -o -follow -name \*.h
! -name modversions.h -print | wc

So I can see the amount of data that the 'find' produces? I'll bet you this is the problem...
I.E. the output of the command between the "`"s that is passed to scripts/mkdep on the command line...

I've looked through the BSP that I'm working with, and I ran into a similar problem.

I chose to modify inux-2.4.26/scripts/mkdep.c to allow for a '-file' arg to take the contents of a file as the list of files to generate the depdendies from instead of getting the list on the command line, and then modified linux-2.4.26/Makefile to break that command into two parts, the first part to do the 'find' and save the results in .hdepend-list, then the 2nd command to call scripts/mkdep with '-file .hdepend-list'.

I believe it is possibel to modify linux-2.4.26/Makefile to take the output of the find, place it into a file, and then split the file up into bite-sized chunks and create the dependecies from that instead of trying to swallow the entire list of files.

I'll look at this possibility and get back to you. You should send a note to Freescale pointing out this problem...

Well that didn't work very well.

scripts/mkdep needs the shole list so it can generate the topological graph of dependencies, and splitting it up creates a *huge* amount of dependencies.

Send me your email address, I need to send you new source for scripts/mkdep.c and a fragment in the linux-2.4.26/Makefile to use the new '-file' arg to scripts/mkdep which will get around this problem.

I had to preface your first line with a "cd ". It is needed to change a directory. The second part found every file on the hard drive. Here is how it ended. I think you need to add a "cd " anyplace you want to change a directory.

The cigwin bash interface has an 'alias' command. I wonder if that would help things. If i could alias the drive/directory down to 3-4 letters, maybe that would be enough. My email here is rnotari@curtisswright.com.

I managed to get the prefix down to "c\linuxbsp\" using the "mount -c" command (did a lot of playing around), but it didn't help, so it looks like it is the number of arguements that is the problem, not the length of the list.

Unfortunatley I can't email you at curtisswright.com, your mailer says that I don't have permission to email you. My mail setup is a bit funky(I don't use logicpd.com to send out emails), so the first email complained about a relay message(which I can understand), so when I tried from my personal domain it was rejected.

Do you have another email address outside of curtiswright.com that I can email you the fix?
