repost: gcc3.1 cross won't find feature_tests.h (and yes, feature_tests.h is just sitting there)

[miki.shapiro@eAladdin.com]

Hi all.
I only got one (unfortunately unhelpful) reply on this, and I'm still stuck
with it, so I'm reposting. Can anyone point out the problem?
Thanks.

Hi, I'm trying to compile gcc3.1 on a SPARC/Solaris8 host that will produce
SPARC/Solaris7 binaries.

I have a main source tree in /usr/src/cross-sparc-sun-solaris2.7/gcc-3.1,
am building into prefix /usr/local
I've already compiled binutils-2.12 and now I configured gcc from
subdirectory build/ with:

../configure --target=sparc-sun-solaris2.7 --prefix=/usr/local -v
--with-headers=/usr/src/cross-sparc-sun-solaris2.7/sol7/include
--with-libs=/usr/src/cross-sparc-sun-solaris2.7/sol7/lib --with-gnu-as
--with-gnu-ld --with-gnu-ar

(I copied headers and libraries from a SPARC/Solaris7 machine to
/usr/src/cross-sparc-sun-solaris2.7/sol7 on this box. Yes, I know I can
copy them directly to the destination in
/usr/local/sparc-sun-solaris2.7/lib and
/usr/local/sparc-sun-solaris2.7/sys-include subdirectories. I like doing it
like this :-) ).

During compilation, I get the following:

================ SNIP =====================

Now, AFAIK, "sys/feature_tests.h" is part of the SUNWhea (Sun Headers)
package on the Solaris CDROM.

1. I *HAVE* this package installed on the Solaris8 host:

#pkginfo |grep SUNWhea
system      SUNWhea              SunOS Header Files

9:55|[May] mikisu:/usr/src/cross-sparc-sun-solaris2.7/gcc-3.1/build#ls -l
/usr/include/sys/feature_tests.h
-rw-r--r--   1 root     bin         5398 Jan  5  2000
/usr/include/sys/feature_tests.h

2. I *HAVE* this package installed on the SPARC/Solaris7 box from which I
took the headers(and libs) from:

(On the Sol7 Box:)
10:06|[December] mikisu:~#pkginfo |grep SUNWhea
system      SUNWhea        SunOS Header Files

(On the Sol8 host box:)
#ls -l /usr/src/cross-sparc-sun-solaris2.7/sol7/include/sys/feature_tests.h
-rw-r--r--   1 bin      bin         5227 Sep  1  1998
/usr/src/cross-sparc-sun-solaris2.7/sol7/include/sys/feature_tests.h

[Possibly-Mistaken] Conclusion: *****They're all there*****

3. I don't know if I should or not, but I do *not* have it in gcc's private
fixinclude'd stock, since fixinclude never makes a fixed version of this
header file:
ls /usr/src/cross-sparc-sun-solaris2.7/gcc-3.1/build/gcc/include/sys
audio_4231.h    ddidmareq.h     exec.h          ieeefp.h
openpromio.h    prsystm.h       types.h
core.h          debug.h         exechdr.h       msg.h           pctypes.h
scsi            user.h
ddi_impldefs.h  ethernet.h      fs              msreg.h         proc
sunddi.h        varargs.h

[SIDENOTE]: If I enter the build/gcc directory and run make from there, it
goes through without a glitch, but if I run "make" in the main build/
directory after that, it does libiberty configure script that eventually
stumbles on the wrongly-built gcc and yells:

=======SNIP=======
.
.
Configuring in sparc-sun-solaris2.7/libiberty..
.
.
checking whether the C compiler
(/usr/share/src/cross-sparc-sun-solaris2.7/gcc-3.1/build/gcc/xgcc
-B/usr/share/src/cross-sparc-sun-solaris2.7/gcc-3.1/build/gcc/
-B/usr/local/sparc-sun-solaris2.7/bin/
-B/usr/local/sparc-sun-solaris2.7/lib/ -isystem
/usr/local/sparc-sun-solaris2.7/include  -m64 -g -O2 ) works... no
configure: error: installation or configuration problem: C compiler cannot
create executables.
.
=======SNIP=======

That's it.
Whelp! :-)
