Re: Cygwin Net - Compilation

Hi Igor,

1.  Thanx for the reply.  The "../include" directory got 
included when I used umsgcc. umsgcc is in /c/ums/bin.

When I used gcc instead, there was no such problem,the 
appropriate gcclib directory got included and I got
this:

-------------------------------------------------------------
gcc -fno-builtin -nostdinc -D __KERNEL__  -
I/home/Administrator/uClinux-dist/linux-2.4.x/include/  -
Wall -Wstrict-prototypes -Wno-trigraphs -O1 -g -fno-strict-
aliasing -fno-common -I/usr/lib/gcc-lib/i686-pc-
cygwin/3.2/./include -pipe -DNO_MM -DNO_FPU -Wa, -
DMAGIC_ROM_PTR -DUTS_SYSNAME=\"uClinux\"   -
DKBUILD_BASENAME=main -c -o init/main.o init/main.c
-------------------------------------------------------------

2. So, I included ums's gcclib: /c/ums/include/gcclib, after
/home/Administrator/uClinux-dist/linux-2.4.x/include/, with 
umsgcc, but still the problem continued.

3. To reduce the length of the include dir above, as
"/home/Administrator/uClinux-dist/linux-2.4.x"  happened
to be the current dir, I put in "./include", instead
of "/home/Administrator/uClinux-dist/linux-2.4.x".

Most of the File Not found errors went away!  One or 2
remained.
I don't seem to understand this spooky behavior...

Do you think it'll help, if I lay out umsgcc as gcc, in
the Cygwin environment, it might help ?

I mean put umsgcc in /usr/bin/.
Have a /usr/lib/machine/gcc-lib/... etc. ? 
I'm trying to get support from umsgcc developers...

THanx a bunch,
best regards,
Deepa
