I've reported the following bug on the Debian BTS: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=663705
for Automake 1.11.3. When I configure MPFR with CC=tcc, as soon as a .c file is modified or I do a "make clean", I get errors when I want to rebuild MPFR. For instance, after a "make clean" and "make": Making all in doc make[1]: Entering directory `/home/vlefevre/software/mpfr/doc' make[1]: Nothing to be done for `all'. make[1]: Leaving directory `/home/vlefevre/software/mpfr/doc' Making all in src make[1]: Entering directory `/home/vlefevre/software/mpfr/src' /usr/bin/make all-am make[2]: Entering directory `/home/vlefevre/software/mpfr/src' exceptions.c \ : /home/vlefevre/dash/bin/dash: exceptions.c: Permission denied make[2]: *** [exceptions.lo] Error 126 make[2]: Leaving directory `/home/vlefevre/software/mpfr/src' make[1]: *** [all] Error 2 make[1]: Leaving directory `/home/vlefevre/software/mpfr/src' make: *** [all-recursive] Error 1 zsh: exit 2 =make The problem appears to be due to the src/.deps/*.Plo files. In the config.log file: configure:4362: checking dependency style of tcc configure:4473: result: icc Of course, there's no such problem with --disable-dependency-tracking. -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <http://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <http://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
