values-X[ac].o missing with sparc-sun-solaris2 cross compiler

values-X[ac].o missing with sparc-sun-solaris2 cross compiler

[John C. Ruttenberg]

I seem to be pretty close to having the cross compiler technology now.  I
managed to build a cross compiler i686-linux -> sparc-sun-solaris2 with only
two "hack" steps.  But the compiler I built doesn't quite work.  It fails in
the linking step with the error:

    /home/rutt/cross/sparc-sun-solaris2/sparc-sun-solaris2/bin/ld: cannot open values-Xc.o: No such file or directory

What is interesting is that values-X.c is supposed to be comming from the
working directory, and not from some "libary" directory:

Using the -ansi command line switch changes the name of the file to

Here are the steps I followed to build my cross compiler:
     
    mkdir ~/cross
    mkdir ~/cross/sparc-sun-solaris2
    mkdir src
    cd src
    tar xfz ~/tmp/egcs-1.0.2.tar.gz
    tar xfz ~/tmp/binutils-2.8.1.tar.gz
    tar xfz ~/tmp/newlib-1.8.0.tar.gz
    cd newlib
    cp -r newlib/libc/include/ ~/cross/sparc-sun-solaris2/  ## Required??
    cd binutils-2.8.1
    configure --target=sparc-sun-solaris2 --host=i686-linux \
              --prefix=/home/rutt/cross/sparc-elf \
              --with-headers=/home/rutt/cross/sparc-elf/include \
              --with-newlib --with-gnu-as
    make all install
    cd ../egcs-1.0.2
    mkdir sparc-sun-solaris2
    cd sparc-sun-solaris2
    ../configure --target=sparc-sun-solaris2 --host=i686-linux \
                 --prefix=/home/rutt/cross/sparc-sun-solaris2 \
                 --with-headers=/home/rutt/cross/sparc-sun-solaris2/include \
                 --with-newlib -with-gnu-ld
    make CFLAGS=-g cross install
    ####
    #### This gets an error trying to build gmon.o that looks like "PATH_MAX"
    #### undeclared.  I'll submit a separate bug report.  So the following
    #### is a workaround for now:
    cd gcc
    touch gmon.o
    cd ..
    make CFLAGS=-g cross install
    #### This time it completes without an error

    cd ../../newlib-1.8.0
    configure --target=sparc-sun-solaris2 --host=i686-linux \
              --prefix=/home/rutt/cross/sparc-elf \
              --with-headers=/home/rutt/cross/sparc-elf/include \
              --with-newlib --with-gnu-as
    make all install

After this simple 25 step procedure, I have a complete tool chain and, as I
said, it almost works.  But not quite because of the horrible values-X*.o
problem.

	/home/rutt/cross/sparc-sun-solaris2/sparc-sun-solaris2/bin/ld: cannot open values-Xc.o: No such file or directory

This file is part of Solaris2.  If you want to get the gcc Solaris2 port
working without using the Solaris2 libraries, then you will need to reverse
engineer it and write a replacement.  This file is in /usr/ccs/lib.

If you only want a sparc cross compiler, and don't need a sparc-sun-solaris2
cross compiler, then try configuring for --target=sparc-elf.  This will
avoid the solaris2 specific stuff that is causing your build to fail.
