Problems making RTEMS with Cygwin !

[Silverio Diquigiovanni]

Hi to all,

I have tried, after many months, to build RTEMS environment for Cygwin,
with a little bug which I'm not able to fix.

This is the question :

- I have installed Cygwin 1.1.2 today with setup directly from internet.
- I have installed RPM
- I have installed last Cygwin RPM tool chain for SuperHitachi SH

Well during configure appears a bug when the script try to compile a C
target source code :

< -- start snip form {build directory}/sh-rtems/c/make/config.log -- >

configure:1242: checking whether the C compiler
(/OPT/RTEMS/BIN/sh-rtems-gcc  ) works
configure:1258: /OPT/RTEMS/BIN/sh-rtems-gcc -o conftest    conftest.c 
1>&5
Assembler messages:
Error: Can't open 
 for reading.

< -- end snip -- >

Then I try to compile a simple test file :

foo.c:
	void foo( void )
	{
	}

01]	sh-rtems-gcc foo.c <cr>
	all work fine and a "a.out" file is generated.

02]	sh-rtems-gcc foo.c -S <cr>
	all work fine and a "foo.s" file is generated.

03]	sh-rtems-gcc foo.c -S <cr>
	sh-rtems-as foo.s -o foo.o <cr>
	all work fine and a "foo.s" & "foo.o" files are generated.

04] 	sh-rtems-gcc foo.c -o foo.o <cr>
	this cause following error message and don't produce files :

	$ sh-rtems-gcc foo.c -o foo.o
	Assembler messages:
	 for reading.open
	: No such file or directory

Thank for your help !
