Problems with Compilation
@ -11,14 +11,31 @@ Problems with Compilation
If you are experiencing problems trying to compile OpenMC, first check if the
error you are receiving is among the following options.
Fatal Error: File 'xml_data_settings_t.mod' opened at (1) is not a GFORTRAN module file
***************************************************************************************
undefined reference to `_vtab$...
*********************************
If you see this message when trying to compile, the most likely cause is that
you are using a compiler that does not support type-bound procedures from
Fortran 2003. This affects any version of gfortran prior to 4.6. Downloading and
installing the latest gfortran_ compiler should resolve this problem.
Fatal Error: Wrong module version '4' (expected '9') for file 'xml_data_cmfd_t.mod' opened at (1)
*************************************************************************************************
The `.mod` modules files that are created by gfortran are versioned and
sometimes are usually not backwards compatible. If gfortran is upgraded and the
modules files for xml-fortran source files are not deleted, this error may
occur. To fix this, clear out all module and object files with :program:`make
distclean` and then recompiling.
Fatal Error: File 'xml_data_cmfd_t.mod' opened at (1) is not a GFORTRAN module file
***********************************************************************************
When OpenMC compiles, the first thing it needs to do is compile source in the
xml-fortran subdirectory. If you compiled everything with a compiler other than
gfortran, performed a :program:`make clean`, and then tried to :program:`make`
with gfortran, the xml-fortran modules would have been compiled with a different
compiler. To fix this, try clearing out all modules and object files with
compiler. To fix this, try clearing out all module and object files with
:program:`make distclean` and then recompiling.
