Re: implications and importance of --prefix?? what about -staticin GCC_EXTRA_CONFIG?

What is the implication/importance of using --prefix for configure? If the excuteable is written to /usr/local/bin, for example, can't I move the binary to /opt and execute it successfully there? The crux of the question is that I need to place the cross compiler in clearcase -- does the path I use with --prefix have to exactly match the path of the binaries and libraries that I'm going to place into clearcase?


Try 'strings /usr/bin/gcc | grep lib/gcc/' and you'll see one of the hardcoded
paths.  The part to the left of the lib/gcc in the output is the value
passed to --prefix during configure, I think.

So yes, --prefix has to match exactly where you're going to run,
unless you're using a very recent (say, released May 2003 or later)
gcc, binutils, and gdb and are building them with --with-sysroot.
Using --with-sysroot with a relative path gets rid of the hardcoded
paths built in to the gcc binaries, or so I'm told. I haven't tried it yet.

One more question...if I want a completely static cross toolchain should I place -static in GCC_EXTRA_CONFIG?

Maybe, but adding LDFLAGS="-static" to the make commandline building the final compiler is what's recommended. See http://sources.redhat.com/ml/crossgcc/2003-10/msg00078.html
