2 bugs with gcc-4.0.1 compilation & installation (errors), Slackware 10, Pentium II

[Martin HRADIL]

Greetings,

I've just compiled (succesfully) gcc-4.0.1 on my slackware box. It's a
Pentium II 266MHz, running linux-2.6.12.3, (old)gcc-3.3.4, glibc-2.3.4.
I used squashfs to hold the unpacked tarball during compilation.

../gcc-4.0.1/configure   --enable-libada --enable-bootstrap=lean 	   \
	--enable-threads --prefix=/usr/local/				   \
	--with-gcc-version-trigger=/root/quak/base/gcc-4.0.1/gcc/version.c \
	--enable-languages=c,c++,java,objc

make CFLAGS='-O' LIBCFLAGS='-O2' LIBCXXFLAGS='-O2 -fno-implicit-templates' \
	bootstrap


I had to restart the compilation a few times because of lack of diskspace
or memory (java) but that's propably my problem.

The first real problem appeared with stage1-gcc/java/jcf-write.o, there
is an unused variable the compiler warns about and -Werror is in CFLAGS.
So I had to add "java/jcf-write.o-warn = -Wno-error" to stage1-gcc/Makefile
(line 208 in my case, just after the "reload1.o-warn = -Wno-error").

It appeared again with stage2-gcc. Same problem, just different Makefile.
(I should have propably changed it in the source, but it was r/o being on
squashfs).

I didn't notice it in stage3 but I'm not 100% sure.

The second problem was that the make install failed with something like
no rule to make ../zlib/libz.a, so:
ln -s stage3-zlib zlib
ln -s stage3-libiberty libiberty
ln -s stage3-libcpp libcpp
ln -s stage3-intl intl
ln -s stage3-gcc gcc
and magically, make install workes fine.


Thanks, keep up the good work,
Martin HRADIL


P.S. the compilation ran from 2005-07-27 to 2005-08-01. Average load ~ 6.
	Java compilation swapped heavily (100MB was not enough)
	(and I have 128MB RAM).

Also I can't really compile a newer version (another week) or try it
on a different machine (none such), sorry :(.
