Hi,
I got hold of the sources via CVS early May (6th May)
and have been on & off at porting the DSS to IRIX.
Well, I can report that I have it more or less
"working"...
I initially used egcs to compile it as gcc fails
(2.95.3, 3.0.1, 3.0.4) with int
ernal compiler error.
gcc isn't exactly well supported on MIPS, certainly
when C++ code is in question...
egcs compile worked but I found that performance was
extremely poor.
Moved over to MipsPro (i.e. SGI's compiler) and
compilation worked althouh I found a few issues:
1. Compiler switches in Makefiles are all gcc/egcs
specific
2. Makefiles use -include pre-processor option (again
gcc/egcs specific) - had to get around this by putting
all the defs from PlatformHeader.h onto compilation
line (in Buildit script) - there must be a better way
to do defines...
3. I got a huge number of warnings that various values
were implicitly cast from
larger to smaller type (didn't see a lot of these
warnings with egcs, but MipsP
ro is a lot more pedantic - this means though that the
code is not as portable as it should be, unless GNU
compilers are used)
In any case, porting wasn't too bad so far, if time
consuming.
I mainly looked for areas with #define for
solaris/linux/MacOSX and looked whether I needed to
add anything (code or another #define)
Found a couple of places that mentioned sgi, and I saw
in early archives that so
mebody has had a go in the past, but nothing since.
In any case, also fixed one of these sections as it
referred to now obsolete ver
sion of IRIX (6.4)
Also had to add a small amount of code for working out
the number of CPUs...
I now have an IRIX install of the DSS which, while
working, is not completely stable.
Streaming of individual files works, but starting the
playlist doesn't (server e
rror). Actually the playlist does start (even if the
admin GUI says that it hasn't), but streaming from the
server causes it to crash...
I've included gdb output at the end of this message.
Basically memory is getting trashed somewhere...
I'll be looking to debug this further, but as I am not
that proficient at C++ (C is my strength), it might
take a while.
What I would like to know, is what would be the
procedure to include my changes in the CVS, and will
they be accepted. Apart from the code I can put in
IRIX Makefiles for MipsPro compilers...
This would make my life easier so that I can keep
getting new code from CVS and not worry about having
to keep updating various files.
Nik.
