[petsc-users] undefined symbol: petsc_null_function_

[Tianhao Le]

Hi Barry,

Attached are the make.log and configure.log.

In fact, the 3-D R-T model is written in c++ and fortran. 

I wrote a wrapper.f90 to let the 3-D R-T model can be called by the python code. (See the Tenstream_combined.csh, also attached)

Thanks,
Tianhao
