Re: Howto build a gcc 4.0 toolchain for ARM?

[-- Attachment #1: Type: text/plain, Size: 16216 bytes --]

this step:

[root at localhost
<http://linux.omap.com/mailman/listinfo/linux-omap-open-source>]# cd
/usr/src
[root at localhost
<http://linux.omap.com/mailman/listinfo/linux-omap-open-source>]# tar
–xjf  gcc-4.0.2.tar.bz2

A configuration file must be modified so that the compiler is built
without libc includes. Edit the
/usr/src/gcc-4.0.2/gcc/config/arm/t-linux file and append

–Dinhibit_libc –D__gthr_posix_h to the line starting with
TARGET_LIBGCC2_CFLAGS =.

The top of the file is shown below, after appending the flags.

# Just for these, we omit the frame pointer since it makes such a big
# difference. It is then pointless adding debugging.
TARGET_LIBGCC2_CFLAGS = -fomit-frame-pointer -fPIC –Dinhibit_libc
–D__gthr_posix_h
LIBGCC2_DEBUG_CFLAGS = -g0

Go to the /usr/src/build/gcc-4.0.2 directory to configure and build
the GNU C compiler with the commands below.

[root at localhost
<http://linux.omap.com/mailman/listinfo/linux-omap-open-source>]# cd
/usr/src/build/gcc-4.0.2
[root at localhost
<http://linux.omap.com/mailman/listinfo/linux-omap-open-source>]#
../../gcc-4.0.2/configure –-target=arm-linux –-prefix=/opt/armv4
--disable-threads –-enable-languages=c
[root at localhost
<http://linux.omap.com/mailman/listinfo/linux-omap-open-source>]# make
isn't working for me io always receive some error

that was crti.o how to fix this ??

[root at localhost
<http://linux.omap.com/mailman/listinfo/linux-omap-open-source>]# make
install
