Solaris 9 crosstool cookbook (long)

["Robert Lippmann" <rlippmann at hotmail dot com>]

Hi all,

After fighting for many days to try and get Dan Kegel's crosstool working on 
Solaris, I
finally succeeded.  I figured I'd document the troubles I ran into (mostly 
due to Solaris
having a default shell of Bourne shell), in the hopes that it would help 
others (and maybe
provide patches to add portability to the tool :)

Anyway, I'm running Solaris 9, and needed to install gcc 3.4.4, glibc 2.3.5 
(because I want
to use this machine as a node for distcc compiles for my gentoo box).

Not sure if there's any difference with Solaris 10, or different versions of 
gcc/glibc,
but hopefully this will serve as a starting point.

I grabbed the GNU stuff from sunfreeware.com (binutils, gawk, coreutils, 
textinfo, gcc, etc).
I made sure that /usr/local/bin was first in my path, and got to work.

First thing I encountered was a problem in getandpatch.sh, namely, the shell 
didn't like:

for arg; do

so I changed both occurrences into:

for arg
do

Next, I needed to fix a patch, namely gcc-3.4.4/fix-fixincl.patch.  Change 
the double quotes
around the sed commands to single quotes:

+SYSTEM_HEADER_DIR = `echo @SYSTEM_HEADER_DIR@ | sed -e :a -e 
"s,[^/]*/\.\.\/,," -e ta`
to
+SYSTEM_HEADER_DIR = `echo @SYSTEM_HEADER_DIR@ | sed -e :a -e 
's,[^/]*/\.\.\/,,' -e ta`

and

+         if test "x${SYSTEM_HEADER_DIR}" = "x`echo 
"${gcc_tooldir}/sys-include" | sed -e :a -
e "s,[^/]*/\.\.\/,," -e ta`";
to
+         if test "x${SYSTEM_HEADER_DIR}" = "x`echo 
"${gcc_tooldir}/sys-include" | sed -e :a -
e 's,[^/]*/\.\.\/,,' -e ta`";

if you don't, when running, you'll receive an error similar to:

chmod 755 ../fixinc.sh

Next, we add a patch to the glibc build bug (Debian Bug #207391).  Create a 
file in the patche
s/glibc-{version} directory, called, say versioninfo.patch:

        fi) > $@T

If you don't do this, at build time, you will see an error like:

make: *** [lib] Error 2

Next, we need to apply the attached patch to crosstool.sh.  It basically 
works around the
fact that configure for the initial glibc header install requires GNU 
binutils, and the
Sunfreeware compiler (and Solaris companion cd gcc) use the Solaris 
linker/assembler.

If you don't apply this patch, you'll see an error like:

checking for makeinfo... makeinfo
checking version of makeinfo... 4.5, ok
checking for sed... sed
checking version of sed... 4.1.1, ok
checking for autoconf... autoconf
checking whether autoconf works... no
configure: error:
*** These critical programs are missing or too old: as ld
*** Check the INSTALL file for required versions.

Finally, we can build.  With a bit of luck, you'll get all the way to the 
point where you get
this error:

which is because ld-linux.so.2 is a 386 elf binary, not sparc.  I'm not 
certain why I didn't
have this problem on a Cygwin build, so a complete fix probably would 
involve seeing what the
Cygwin build did to work around this problem (or not run into it in the 
first place).

Anyway, all this step appears to be doing is running getconf on the 
installed headers to find
out what _POSIX_V6_WIDTH_RESTRICTED_ENVS is.  According to my linux box, it 
should be:

[rlippmann@akko ~]$ getconf _POSIX_V6_WIDTH_RESTRICTED_ENVS
POSIX_V6_ILP32_OFF32
POSIX_V6_ILP32_OFFBIG

so, we edit build/*/*/glibc-{version}/posix/Makefile, and change the long, 
ugly:

for spec in .... \
; do

to

for spec in POSIX_V6_ILP32_OFF32 POSIX_V6_ILP32_OFFBIG \
   ; do

and re-run (don't forget to use --nounpack, or you'll hose these changes).

Voila, you should have a complete linux toolchain on Solaris.
