Dear Greg , Masanori-san and others ,
Thank you very much for adding support for the SH3
compilation in microwindows.
But please make some changes :-
In config file :-
replace
SHTOOLSPREFIX = sh-linux-gnu
with
SHTOOLSPREFIX = sh-linux-gnu-
and
In Arch.rules file :-
replace
CFLAGS += -m1 -m3 -Wall $(OPTFLAGS)
with
CFLAGS += -ml -m3 -Wall $(OPTFLAGS)
It is ml (l means little-endian)
To build microwindows for SH :-
i also made changes in
1. config file
replace
ARCH = LINUX-NATIVE
with
ARCH = LINUX-SH
and
replace
FBVGA = Y
with
FBVGA = N
2. drivers/vgaplan4.h
replace
#include <sys/io.h> /* for outb def's, requires -O */
#include <asm/io.h> /* for outb def's, requires -O */
3. drivers/scr_fb.c
replace
#include <sys/io.h>
requires -O */
#include <asm/io.h>
Then i am able to build binary files and libraries of
microwindows.
but when i run ./mterm or ./mdemo
i get :-
Error opening /dev/fb0 , no such file or directory
Cannnot initialize screen
Then i made in dev directory:-
mknod fb0 c 29 0
ln -s fb fb0
Then i run again ./mterm or ./mdemo
i got "screen cleared and no output" same as
Masanori-san get .
Please tell me what i have to do , to rectify this
problem.
Thanks,
Jaswinder.
