- Compilation
- Problems compiling syscalls
- Unable to open include file: chemistry.h
- Compiling with ifc under Linux
- Segmentation fault with ifort 8.0 under Linux
- The underscore problem: linking with MPI
- Compilation stops with the cryptic error message:
- The code doesn't compile,
- Some samples don't even compile,
- Internal compiler error with Compaq/Dec F90
- Assertion failure under SunOS
- After some dirty tricks I got pencil code to compile with MPI, ...
- Error: Symbol 'mpi_comm_world' at (1) has no IMPLICIT type
- Error: Can't open included file 'mpif.h'
- Pencil check
- The pencil check complains for no reason.
- The pencil check reports MISSING PENCILS and quits
- The pencil check reports unnecessary pencils
- The pencil check reports that most or all pencils are missing
- Running the pencil check triggers mathematical errors in the code
- The pencil check still complains
- The pencil check is annoying so I turned it off
- Running
- Periodic boundary conditions in start.x
- csh problem?
- run.csh doesn't work:
- Code crashes after restarting
- auto-test gone mad...?
