Hello, I have a problem with one of the projet I am trying to convert to autoconf/automake. during the configure process, I got plenty of rm: cannot remove `core': Is a directory yes checking for sys/types.h... rm: cannot remove `core': Is a directory yes checking for sys/stat.h... rm: cannot remove `core': Is a directory yes checking for stdlib.h... rm: cannot remove `core': Is a directory yes checking for string.h... rm: cannot remove `core': Is a directory yes checking for memory.h... rm: cannot remove `core': Is a directory yes checking for strings.h... rm: cannot remove `core': Is a directory yes checking for inttypes.h... rm: cannot remove `core': Is a directory yes checking for stdint.h... rm: cannot remove `core': Is a directory yes checking for unistd.h... rm: cannot remove `core': Is a directory yes checking for dlfcn.h... rm: cannot remove `core': Is a directory yes Indeed one directory of the project is named 'core'. Nevertheless once done with the configuration, 'make' works like a charm and I obtain the right library. now to trigger the real effect of this annoying message, the distcheck target need to be be used It gives this error ERROR: files left in build directory after distclean: ./confdefs.h so it seems to me that it should be allow to have a core directory in a projetc, this is a valid name. So the logic when removing core files, would be to check first thta they are real file and not a directory. what is you opinion, is it an autoconf bug ?
