Nicolas Boulenguez <nicolas at debian dot org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |nicolas at debian dot org --- Comment #9 from Nicolas Boulenguez <nicolas at debian dot org> --- Hello. I had the failure with GCC-10.2.1, only when running `autoreconf -f -i . fixincludes gcc subdirs...` before `./configure`. For each subdir in turn, autoreconf checks if the subdirectory uses libtool or automake. If so, it installs depcomp in . (../ from the subdir), else removes ./depcomp (breaking the build of other subdirectories). Changing the order of autoreconf arguments so that the last one depends on automake fixed the problem for me. I am not sure if this is a bug, or where to report it, but documenting the work-around here may be useful to other GCC users.
