Hello Michael! Hello All! On Tuesday 29 July 2008 16:28:09 Michael Abbott wrote: > Just discovered that $PREFIX-populate has absolute paths.

So that the toolchain can be relocatable, right? > (Here I'm assuming there's something like CT_PREFIX symbol to substitute > here.) In fact that's ${CT_TARGET}. > Is it as simple as this? Alas, tha't s not so easy: - I'm not sure that $0 always has the complete path - gcc -print-prog-name=readelf always yields 'readelf', and never the cross-readelf... :-( - gcc has no option to tell where the sysroot it uses is. Maybe something like the following would work: # Detect where the toolchain is: case "${0}" in /*) BIN_DIR="$(dirname "${0}")";; */*) BIN_DIR="$(pwd)/$(dirname "${0}")";; *) BIN_DIR="$(dirname $(which "${0}"))";; esac CT_READELF="${BIN_DIR}/@@CT_TARGET@@-readelf" CT_SYSRROT_DIR="${BIN_DIR}/../@@CT_TARGET@@/sys-root" > P.S.
