[petsc-users] errors in compiling ~\petsc-3.2-p7\src\ksp\ksp\examples\tutorials\ex2f.F

[Roc Wang]

Hello,
I am trying to compile the example source code of ~\petsc-3.2-p7\src\ksp\ksp\examples\tutorials\ex2f.F. However the error information shows:
ex2f.o: In function `MAIN__':ex2f.F90:(.text+0x1b): undefined reference to `_gfortran_set_std'ex2f.F90:(.text+0x6f1): undefined reference to `_gfortran_st_write'ex2f.F90:(.text+0x706): undefined reference to `_gfortran_transfer_real'ex2f.F90:(.text+0x71b): undefined reference to `_gfortran_transfer_integer'ex2f.F90:(.text+0x727): undefined reference to `_gfortran_st_write_done'ex2f.F90:(.text+0x773): undefined reference to `_gfortran_st_write'ex2f.F90:(.text+0x788): undefined reference to `_gfortran_transfer_integer'ex2f.F90:(.text+0x794): undefined reference to `_gfortran_st_write_done'ex2f.o: In function `mykspmonitor_':ex2f.F90:(.text+0x896): undefined reference to `_gfortran_st_write'ex2f.F90:(.text+0x8ae): undefined reference to `_gfortran_transfer_integer'ex2f.F90:(.text+0x8ba): undefined reference to `_gfortran_st_write_done'ex2f.F90:(.text+0x924): undefined reference to `_gfortran_st_write'ex2f.F90:(.text+0x93c): undefined reference to `_gfortran_transfer_integer'ex2f.F90:(.text+0x954): undefined reference to `_gfortran_transfer_real'ex2f.F90:(.text+0x960): undefined reference to `_gfortran_st_write_done'make: *** [ex2f] Error 1  
My makefile is like this:

Should there any more libraries be included in the makefile?
