hello. I've checked out the whole l4 tree from the DROPS CVS and i'm trying to build it all (Fiasco, packages, etc). But it gaves me the following error: make[3]: Entrando no diretório `/home/tiago/l4/pkg/loader/examples' test -f dump-l4/broken -o -f dump-l4/obsolete || \ if [ -f dump-l4/Makefile ] ; then PWD=/home/tiago/l4/pkg/loader/examples/dump-l4 make -C dump-l4 ; fi make[4]: Entrando no diretório `/home/tiago/l4/pkg/loader/examples/dump-l4' PWD=/home/tiago/l4/pkg/loader/examples/dump-l4/OBJ-x86_586-l4v2 make -C OBJ-x86_586-l4v2 -f Makefile make[5]: Entrando no diretório `/home/tiago/l4/pkg/loader/examples/dump-l4/OBJ-x86_586-l4v2' make[5]: Nada a ser feito para `all'. make[5]: Saindo do diretório `/home/tiago/l4/pkg/loader/examples/dump-l4/OBJ-x86_586-l4v2' make[4]: Saindo do diretório `/home/tiago/l4/pkg/loader/examples/dump-l4' test -f fprov-l4/broken -o -f fprov-l4/obsolete || \ if [ -f fprov-l4/Makefile ] ; then PWD=/home/tiago/l4/pkg/loader/examples/fprov-l4 make -C fprov-l4 ; fi make[4]: Entrando no diretório `/home/tiago/l4/pkg/loader/examples/fprov-l4' PWD=/home/tiago/l4/pkg/loader/examples/fprov-l4/OBJ-x86_586-l4v2 make -C OBJ-x86_586-l4v2 -f Makefile make[5]: Entrando no diretório `/home/tiago/l4/pkg/loader/examples/fprov-l4/OBJ-x86_586-l4v2' ...
