multiple compilations

[Davide Fasoli]

I'm writing this mail about some problem i had during the l4 microkernel installation..

when running this command from shell

make O=/home/fasoz/soa/tudos/l4/prova

where /home/fasoz/soa/tudos/l4/prova is the installation directory of l4, I had the following text as output:

...
make -C build
make[2]: Entering directory `/home/fasoz/soa/tudos/kernel/fiasco/build'
make srcdir=/home/fasoz/soa/tudos/kernel/fiasco/src objbase=/home/fasoz/soa/tudos/kernel/fiasco/build -f /home/fasoz/soa/tudos/kernel/fiasco/src/Makefile.sub1

I was wondering about what can cause this error, i spent something like 15 days on this without coping on... could you please help me? I need to install l4 for an exam...

thanks in advance
