* Add support for more drivers to shgen !!!!
|
||||
|
||||
* shgen relies on having a gnu-compatible getopt, which should be
|
||||
available on all hosts using gcc/egcs/binutils.
|
||||
Using other getopt-variants may produce faulty results or shgen may also
|
||||
refuse to compile. Probably the easiest solution to this problem would be
|
||||
to integrate libiberty into rtems.
|
||||
|
||||
* shgen uses floating point mathematics. Therefore Makefile.in contains a
|
||||
reference to libm. In case the host doesn't have its floating point
|
||||
support in libm, shgen will fail to compile. If we should ever meet such
|
||||
a host, checks for floating point libraries have to be added to rtems'
|
||||
autoconf support.
