I see several issues with this log excerpt: - the first libtool link command uses /usr/lib as a host path (second line) this needs fixing - the second libtool command does not use the cross-linker, and for that I have no idea yet > > This problem is described here : > http://www.metastatic.org/text/libtool.html > > > I have two questions at this point : > 1) I sew that OpenWRT buildsystem uses staging_dir/host/bin/libtool. > If this (host) libtool is normally used for building packages and not > cross compiled libtool, did I do something wrong in my Makefile? The compiled libtool resides in host because it is actually compiled for the host system, there is no other libtool executable in the build system besides those copies provided by other packages we build. > > 2) If some other, cross-compiled libtool should be used, where can I > find it?
