Hello all,
I followed the document "Building the GNU toolchain for ARM targets" by
Chris Rutter to build a cross compiler on my i586 machine.
I got the tools and utilities which were needed for the steps:
1. binutils-2.9.5.0.22
2. linux-2.3.33 with patch-2.3.33-rmk3
3. gcc-2.95.2
4. glibc-2.1.2
First I built biutils using the following command:
# ./confure --targeet=arm-linux --prefix=/usr
# make ; make install
I successed install binutil at the /usr/arm-linux
Second, I reconfig kernel's System and processor type
I select (RiscPC)ARM system type and enable the menus of "Support ARM610"
and "Support ARM710"
then
# make dep
#cp -dR /linux/include/arm-arm /usr/arm-linux/asm
#cp -dR /linux/include/linux /usr/arm-linux/linux
Then I config gcc
#./configure --target=arm-linux --prefix=/usr
and fix a flag in gcc/config/arm/t-linux file:
TARGET_LIBGCC2_CFLAGS = -fomit-frame-pointer -fPIC
to
TARGET_LIBGCC2_CFLAGS
= -fomit-frame-pointer -fPIC -Dinhibit_libc -D__gthr_posix_h
Now I reconfig gcc
#./configure --target=arm-linux --prefix=/usr --disable-threads
The compiler error message is my problem:
.............
checking for sys/wait.h is POSIX.1 compatible... no
checking whether the C compiler
(/usr/src/gcc-2.95.2/gcc/xgcc -B/usr/src/gcc-2.9.5.2/gcc -B/usr/arm-linux/bi
n/ -g -O2) works... no
configure :error : installation or configuration problem: C compiler cannot
create executables.
>>>Q. How do I fix this problem ?
>Then gcc quit with following error : gcc compiling directory
/usr/src/gcc-2.95.2/arm-linux/libio
/usr/src/gcc-2.95.2/gcc/xgcc -B/usr/src/gcc-2.95.2/gcc -B/usr/arm-linux/bin

>then quit...
The error message tell me that gcc can't find the header file ,and I find
/usr/include has _G_config_h
My question is why compile switch don't include "-I/usr/include" ? Can I
just use the file ?
Kevin,
Regards.
