Thanks Ian, that's great, GOLD is a nice work. I plan to take the
gold/powerpc.cc & elfcpp/powerpc.h as my start point.
But I still have some questions. At first I have tried to compile the gold
separately with following command :
but error occurs:
errorï ../bfd/bfdver.hïno such file or directory
make: *** [options.o] error 1
make: *** [all-recursive] error 1
make: *** [all] error 2
So can I compile the gold separately ?
No, you're right, the unmodified sources do require that the BFD
library be built. But the only file that is required from BFD is in
fact bfdver.h, and it is only used for the output of gold --version
and --help. You could write your own copy of that file (look for
bfdver.h in bfd/Makefile.am) and not bother with the rest of BFD. In
particular BFD does not have to actually work for your processor.
and the run the aclocal & autoconf , but errors
configure.in:116: warning: macro `AM_BINUTILS_WARNINGS' not found in library
configure.in:116: error: possibly undefined macro: AM_BINUTILS_WARNINGS
If this token and others are legitimate, please use m4_pattern_allow.
See the Autoconf documentation.
It looks like you didn't pass the right options to aclocal. It's
easier to simply run autoreconf. If you really want to run aclocal,
run "aclocal -I . -I .. -I ../config".
By the way, I have used the option "--enable-maintainer-mode" at the first
try, Will this option update the configuration script automatically ?
It will cause the configuration script to be updated when you run
"make" if any of the inputs files are out of date. You still have to
get the right configuration scripts the first time around.
