I'm using multiple configurations of binutils/GCC in parallel - Cygwin, MinGW, an i586-elf and a arm-wince cross compiler.
I know my way around in a Unix environment, but the fine print of administering a system escapes me. Thus, so far my four compilers are scattered all over the filesystem. The preinstalled Cygwin and MinGW installations are in /usr, and the cross- compilers I installed in /usr/cross-elf and /usr/cross-arm using the "configure --prefix" option.
This is unwieldly. I've seen the GCC "-b" option that apparently allows to specify the target machine in some kind of parallel GCC setup (as in "gcc -b i586-elf", if I understood it correctly), and would much prefer to enable that.
But search as I might (including several Google's for "parallel GCC installation" or "cross-compiler parallel" or ...), I haven't found any guideline on how to add additional targets to an existing GCC installation.
I see that target-specific directories should end up in /usr, where already /usr/i686-pc-cygwin and /usr/i686-pc-mingw32 reside. But if I just "configure --prefix=/usr --target=i586-elf", I would overwrite those parts of the existing installation that reside in /usr/bin and /usr/lib, no?
How do I set up multiple parallel GCC installtions?
