Hi Jim, The module 'unlink-busy' does not support cross-compilation: It uses AC_RUN_IFELSE, thus calling the compiler for the host, and then sets INSTALL, which is meant to point to a command to execute on the build machine.
It should IMO better use the compiler for the build machine, but this isn't easily available in Autoconf. Or just replace this entire macro outright with AC_REQUIRE([AC_CANONICAL_BUILD]) case "$build_os" in hpux* | mingw*) INSTALL=$ac_install_sh ;; esac And why isn't the determination of the INSTALL variable part of Autoconf proper? What do you think? Bruno
