This problem exists on fully up-to-date versions of 9.10. There do not seem to be any bugs reported on this issue in Launchpad (searching for combinations of "autoconf", "2.64", "2.65", "9.10"). autoconf 2.64 introduced a change to the AC_PROG_CC macro that breaks compiling for the AVR (the processor used in the popular Arduino project). The macro attempted to compile a small program that uses "fopen", which is not included in avr-libc. While this is not standards compliant, it makes sense: most AVR microcontrollers have between 2K and 32K of flash. The result of this macro change is that compiling for the AVR using the autotools is broken in Ubuntu 9.10. Until this is fixed/updates, projects that build code for the AVR cannot be built on Ubuntu 9.10. The problem was reported against autoconf, and the discussion thread can be found here: http://thread.gmane.org/gmane.comp.sysutils.autoconf.bugs/6839 The patch against 2.64 that fixed the problem is here: http://thread.gmane.org/gmane.comp.sysutils.autoconf.bugs/6839 The problem no longer exists/was fixed in autoconf 2.65. Or, if you prefer, it is possible to compile code using the autotools for the AVR series of microcontrollers using autoconf 2.65.
