Then you can build coloredstderr for all architectures and use +'$LIB' in 'LD_PRELOAD'. The following should work for Debian-based systems +with this directory structure: + + dir + `-- lib + |-- i386-linux-gnu + | `-- libcoloredstderr.so + `-- x86_64-linux-gnu + `-- libcoloredstderr.so + +Now set 'LD_PRELOAD'. `lib/` is included in '$LIB'! + + LD_PRELOAD='/absolute/path/to/dir/$LIB/libcoloredstderr.so' + +The single quotes are important. '$LIB' is not evaluated by the shell, but by +the loader (`man ld.so`). Now both i386 and amd64 binaries automatically use +coloredstderr. + The following additional environment variables are available:
