RE: uClinux/arm-elf-linux

I'm sure of the assembler not getting an input file now.

If I run the assembler with a filename of a nonexistent file: nofile, the
error output is as follows:

$ /usr/local/arm-elf/bin/as.exe nofile
Assembler messages:
Error: Can't open nofile for reading.
nofile: No such file or directory

Now if you look at were nofile is listed in the error message:

Error: Can't open nofile for reading.

Replace it with a CR that starts the rest of the text at the beginning of
the line, and you get:

 for reading.open

Then eliminating nofile in the No such file message gives:

Assembler messages:
 for reading.open
: No such file or directory

Which is exactly what's coming out of the assembler when its involked by
gcc.

I fear I'm about to be reprimanded again for trying to use cygwin. Maybe I
should post this to the cygwin list. It might be worth a post to the
binutils list too, since it seems this error could use some explicit testing
or handling.

Thanks Again for any suggestions that might lead me out of this. (and I am
trying to get a suitable GNU/Linux development platform setup here, I don't
think my old '486 will do)

Thanks for the paragraphs Bill!

I hope you write that book, lay claim to your O'Reilly animal now, they're
going fast 8-)

I've got an arm-elf-gcc, built with newlib.

When I try to build uClibc or newlib with it I get the reading.open error.
So I made a simple test.c and ran the cross compiler on it:

arm-elf-gcc -save-temps -v test.c -o arm-elf-test

This results in the same error (see below).

If I run: /usr/local/arm-elf/bin/as.exe test.s

On the saved test.s file it assembles successfully.

It seems for some reason the file isn't being passed to the assembler, it's
just getting a blank argument list. Its the same when the files are created
in the TEMP directory or when -save-temps is specified.

I'm still beggin' for clues. Thanx for all the help!!!
