[ECOS] Problems compiling sim/ppc/emul_unix.c

[ECOS] Problems compiling sim/ppc/emul_unix.c

[Michael Martin]

Hi all,

i currently are in the process of building the ecosSWtools-990319
for the powerpc target under Solaris2.5.1 and got a problem
compiling .../ecosSWtools-990319/src/sim/ppc/emul_unix.c
In line 88 (in the 
' #ifdef HAVE_TERMIOS_STRUCTURE 
  ... 
  #endif'
section)
someone has disabled the
' #undef termio
  #define termio termios
'
section with an '#ifdef 0 ... #endif' because it breaks the build under RedHat
5.0.
Under Solaris2.5.1 we have both 'sys/termio.h' and 'sys/termios.h'.
Because of the '#undef HAVE_TERMIO_STRUCTURE' in line 85 in emul_unix.c
'sys/termio.h' is not included any more and so the structure 'struct termio' is
unknown. Also because of the '#ifdef 0' in line 88, 'struct termio' is not
defined
to be 'struct termios', so i got the problem of declaring an unknown struct
in the parameter list of a function in line 1242.
To workaround this you have to comment out the '#ifdef 0 ... #endif' in
lines 88 and 91.
A general remark: Do not do those fixes for one OS (in this case RedHat 5.0),
if you are not sure that it does not affect others.

Just for the record, there is already a patch for this,
http://sourceware.cygnus.com/ml/ecos-discuss/1999-02/msg00003.html
with a pointer to the patch in the eCos sourceware FAQ. There were
some other Solaris-related build problems identified in the same
discussion.
