>Subject: Re: [PATCH] Fix building kernel under Solaris
Since Solaris seems to be on the run, I did myself try compile it.
However, unlike the original poster who said he did so on SunOS 4.8, I
did it on 5.11_snv39, yielding a bigger changeset. I thought I just
share the diff that piled up so far. It needs a lot of hacks on the
Solaris side - prioritizing GNU names, then, second, gnu ld has a
glitch, then, gcc has a missing file... it's fun fun fun!
Well, I will iterate the key problem with the missing file:
* include/linux/kernel.h (and many others) include <stdarg.h>
BUT - since we are using -nostdinc, /usr/include/stdarg.h is not
considered. And gcc's stdarg.h (which lives at
/usr/lib/gcc/i586-suse-linux/4.1.2/include/stdarg.h in Linux land)
is missing in Solaris' GCC (which is version 3.4.3).
Hack #1:
ln -s \
/usr/sfw/lib/gcc/i386-pc-solaris2.11/3.4.3/install-tools/include/stdarg.h \
/usr/sfw/lib/gcc/i386-pc-solaris2.11/3.4.3/include/stdarg.h
Hack #2: GNU programs...
mkdir -p ~/gnulink;
for i in addr2line ar as egrep grep ld make nm objcopy objdump \
ranlib readelf size string strip tar; do
ln -s "/usr/sfw/bin/$i" "~/gnulink/$i";
done;
for i in cat chgrp chmod chown chroot cksum cmp cp cut date \
dd df diff du echo env expand expr false fgrep find fold \
getopt groups head hostid install join ln locate ls mkdir \
mkfifo mknod mv nice nohup od pwd rm rmdir sed seq shred \
sleep sort split stty tac tail tee touch tr true uname \
uniq uptime wc who whoami xargs yes gawk; do
ln -s "/opt/csw/bin/$i" "~/gnulink/$i";
done;
Hack #3: Diff file...
Hack #4: GNU ld glitch workaround (GNU ld looks in the current dir...)
cd linux-2.6.21-rc3
ln -s /usr/sfw/i386-sun-solaris2.11/lib/ldscripts ldscripts
Fun #1:
export PATH="$HOME/gnulink:$PATH";
make ARCH=i386
Oddity #1:
ARCH=i386 required because the Makefiles seem to use `uname -m`
(which returns "i86pc") rather than `uname -p`. I think we are
at odds here though...
uname -m uname -p
SOL i86pc i386
LINUX i686 athlon
Expect compiler failures, especially with assembler code.
