I assume that sub7 means Seed7.

The make utility is used to manage the compilation process.
The make utility uses a file named 'makefile' which contains
informations about what files need to be processed (by the compiler
or other tools) and the dependencies between this files. The
'makefile' contains rules to generate files. There are some precoditions
(other files) which need to be present before some commands get
executed which should create the file described with this rule.
A detailed explanation of the make utility is here:

Usually the command 'make depend' should create the file
'version.h'. When I execute 'make depend' it starts with:

tm@penguin:~/seed7_5/seed7/src$ make depend
echo "#define ANSI_C" > version.h
echo "#define USE_DIRENT" >> version.h
echo "#define PATH_DELIMITER '/'" >> version.h
echo "#define CATCH_SIGNALS" >> version.h
echo "#define USE_MMAP" >> version.h
echo "#undef  INCL_NCURSES_TERM" >> version.h
echo "#undef  INCL_CURSES_BEFORE_TERM" >> version.h
echo "#undef  MKDIR_WITH_ONE_PARAMETER" >> version.h
...

For me this looks like a previous attempt with 'make depend' was
somehow stopped (e.g. with CTRL-C or by an error in the makefile)
and the file 'version.h' was not completely generated.
How does your file 'version.h' look like?

This is another indication that the 'version.h' file was not created correctly.
A correct 'version.h' file should contain a #define for SEED7_LIBRARY.
on my computer 'version.h' contains the line:

#define SEED7_LIBRARY "/home/tm/seed7_5/lib"

I suggest you to start from the beginning with the command:

  make clear

This removes all files created by previous calls of 'make'. Afther that
use

  make depend

and finally

  make

this should work.

If the same error happens again or some other error shows up
please send me the file 'version.h' and the log again (just to be sure).
