Hi,

questions.
Do you still remeber what did to get around this problem? I believe a
lot
of people are looking for your successful story!

I always end up with the following errors:
Checking version of arm-linux... gcc 2.95, bad
......
*** Some critical program is missing or too old.
What I did is as follows:
Install binutils-2.9.1.0.25.tar.gz without any patches
Install linux-2.2.10.tar.gz with patch-2.2.10-rmk3.gz
cp -a /usr/src/linux-2.2.10/linux/include/arm-asm
/usr/arm-linux/inlcude/asm
cp -a /usr/src/linux-2.2.10/linux/include/linux
/usr/arm-linux/include/linux
Install gcc-2.95.tar.gz
./configure --target=arm-linux --prefix=/usr
make LANGUAGES=c
Now it complains "stdlib.h: No such file or directory"
Edit gcc/config/arm/t-linux and add "-Dinhibit_libc" and
"-D__gthr_posix_h"
to TARGET_LIBGCC2_CFLAGS
Delete #include "gthr.h" in libgcc2.c
Add the "--disable-threads" option to configure
Then it tries to remove some directory and complains it is not
empty, I removed it manually and resume "make LANGUAGES=c", it
finished
w/o error, and I can do "make LANGUAGES=c install"
Install glibc-2.1.tar.gz with glibc-linuxthread-2.1.tar.gz and
glib-crypt-2.0.111.tar.gz
./configure arm-linux --build=i686-pc-linux-gnu --prefix=/usr/arm-linux
--enable-add-ons
Now comes to "gcc 2.95, bad"
I also tried Werner's directions as follows:
Build gcc:
- get the following files
ftp://egcs.cygnus.com/pub/egcs/snapshots/1999-06-23/egcs-core-19990623.tar.gz
ftp://ftp.netwinder.org/users/p/philb/gcc-2.95-diff-990623.gz
ftp://lrcftp.epfl.ch/pub/people/almesber/psion/egcs-19990623-xdev-1.patch.gz
- be sure to have bison and autoconf installed
- tar xfz egcs-core-19990623.tar.gz
- cd egcs-19990623/gcc/config/arm
- zcat ../../../../gcc-2.95-diff-990623.gz | patch -s
- cd ../../..
- zcat ../egcs-19990623-xdev-1.patch.gz | patch -p1 -s
- if very short on space, rm ../egcs-core-19990623.tar.gz now
- ./configure --target=arm-linux --prefix=/scratch/psion/xdev
--disable-threads
- make cross
It will stop after a while with with
make[1]: *** No rule to make target `c++', needed by `native'.
Stop.
make[1]: Leaving directory
`/scratch/psion/xdev-1/egcs-19990623/gcc'
make: *** [cross] Error 2
- make install LANGUAGES=c
This one should finish without errors.
Again, when I tried to config glibc-2.1, it complains "gcc 2.95, bad"
Thanks,
