You will need to build a complete set of cross-tools, including the linker from the GNU binutils. In fact, you should build the cross-binutils before you build the cross-gcc. > Am I supposed to create the same path to the Solaris libraries and > system files on my Linux box when I build the cross compiler as are in > use on the Solaris machine? The path itself doesn't have to be the same, and indeed since you will be copying over /usr/include it should not be the same--you don't want to replace your Linux /usr/include with the Solaris /usr/include. Instead, pick a system root, e.g. /home/randux/solaris. Then copy the files from Solaris into that root, so that you wind up with, e.g., /home/randux/solaris/usr/include. Then run configure using --with-sysroot=/home/randux/solaris. > I forgot to ask, is the target reall sparc-sun-solaris for Solaris on > Intel? This is one of the confusing things. I couldn't find on the gcc > web pages which target to specify for x64 Solaris. I'm not sure that gcc has explicit support for x86_64 Solaris systems. That might be very easy to add, I don't know. For 32-bit Intel Solaris systems use something like i686-sun-solaris2. Ian
