I cannot cross compile any packages which depend on guile. The configure phase either fails to find the autoconf macros or fails to find guile itself. >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> configure: checking for guile 3.0 configure: found guile 3.0 checking for guile-3.0... no checking for guile3.0... no checking for guile-3... no checking for guile3... no checking for guile... no configure: error: guile required but not found <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< or >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> configure.ac:70: error: possibly undefined macro: GUILE_PKG If this token and others are legitimate, please use m4_pattern_allow. See the Autoconf documentation. configure.ac:71: error: possibly undefined macro: GUILE_PROGS <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< I've tried compiling guile-config, guile-quickcheck, and guile-udev with --target=arm-linux-gnueabihf and --target=aarch64-linux-gnu and all fail in similar ways. Guile itself cross-compiles fine and is listed as an input (not a native-input) on all of these packages. Thanks, Mitchell
