[petsc-users] Double-colon target

[Tuan Nguyen]

Dear all,

I installed PETSC 3.1-p8 library. I am trying compile the fortran code link
to Petsc but there is message saying about target file as follow:

*​**​*
*petsc-3.1-p8-openmpi/conf/rules:120: *** target file `clean' has both :
and :: entries.  Stop.*

​In my "makefile" I added double-colon to target clean but it will bring me
to another error message:
*​*





*/home/petsc-3.1-p8-openmpi/conf/rules:299: warning: overriding commands
for target `.c.o'makefile:39: warning: ignoring old commands for target
`.c.o'/home/petsc-3.1-p8-openmpi/linux-gnu-c-debug/conf/petscrules:31:
warning: overriding commands for target `.F.o'makefile:42: warning:

`.F.o'/home/petsc-3.1-p8-openmpi/linux-gnu-c-debug/conf/petscrules:31:
warning: overriding commands for target `.F90.o'makefile:47: warning:
ignoring old commands for target `.F90.o'*
/bin/rm -f *.o *.mod *.f90

​Could any one help me?

Thanks,​

Tuan
