Hi Erik and everyone else,
I read the article
http://www.armlinux.org/docs/toolchain and tried to
compile gcc according to it, but I got big problem!!
I tried even more that Marr, I tried gcc-2.8.1.tar.gz
gcc-2.95.2.tar.gz gcc-core-2.95.3.tar.gz
gcc-2.95.3.tar.gz nothing works!! I couldn't compile
any of them.
According to the article, I downloaded the latest
version linux-2.4.5.tar.gz, and edit Makefile changed
ARCH := $(shell uname -m ...) to ARCH=arm, (I also
find another paper says change it to ARCH := arm,
which is correct????????), I don't know what I should
put after CrossCompile = . and the make menuconfig
didn't display the configure menu correctly! it only
displays
three menu item,
------
Load an Alternate configuration File
Save Configuration to an Alternate File
So, there is not 'System and processor type' menu item
at all! Then, I tried linux-2.4.4.tar.gz, it is the
same as linux-2.4.5.tar.gz, and Finally I found
linux-2.4.2.tar.gz works, it could has that menu item,
and I fired make dep
After that I tried to compile that 3 version of gcc,
none could be compiled. (by the way, I tried to access
ftp://ftp.armlinux.org/pub/toolchain to get patch for
gcc, but ftp can be accessed), I also applied the
-Dinhibit_libc hack. but I alway got libgccl.S(maybe
libgccl.c) error, can't find unistd.h
I am using RedHat 7.0 the kernel should be 2.2.16-22
Please read attachment to find what I did exactly.
Please help me, I have do that for one week!
Thanks in advance.
