OK, I decided to try Cello/Linux first since I have actually used CMUCL and Emacs on this box successfully in the past. Managed with the usual amount of grief to CVS down the Freeglut sources into /usr/local/freeglut/freeglut (their fault, not mine). Tried what I thought was the way to go: ./configure ...with the directory containing configure.in as my working directory. Shell yells no such command. So I try: autoconf ...and get: root@xkenny:~# cd /usr/local/freeglut/freeglut root@xkenny:/usr/local/freeglut/freeglut# autoconf configure.in:4: error: possibly undefined macro: AM_INIT_AUTOMAKE If this token and others are legitimate, please use m4_pattern_allow. See the Autoconf documentation. configure.in:5: error: possibly undefined macro: AM_CONFIG_HEADER configure.in:11: error: possibly undefined macro: AC_LIBTOOL_DLOPEN configure.in:12: error: possibly undefined macro: AM_PROG_LIBTOOL configure.in:35: error: possibly undefined macro: AC_CHECK_LIBM I understand the Freeglut stuff is pretty tight, and someone here built Freeglut successfully, so... what am I doing wrong? In case it is not clear, I am clueless on Linux, so plz err on the side of more specifity with any advice. I'll keep digging, but I thought I would send up a flare before running out for pizza. kt
