D.gnu - GDC on Mac OS X 10.2 - compat issues

reply =?ISO-8859-1?Q?Anders_F_Bj=F6rklund?= <afb algonet.se> writes:
Upon requests, I was trying to compile a GDC
version for (legacy) Mac OS X 10.2 "Jaguar",
using "Dec. 2002" Developer Tools with extra
"Aug 2003" gcc update to get GCC version 3.3...

(Tried to cross-compile it at first, but no luck.
Seems I always manage to trigger compiler crashes)


Here are the compatibility issues, that I ran into:

1) <wchar.h> is missing. ("wchar_t" is in <stdlib.h>)
    Think that this header is a C99 feature, perhaps?

2) <alloca.h> is missing (alloca is in <stdlib.h> too)

3) wcslen is missing, and has to be added from compat
    library. Only needed this function, so I hacked it

4) dlfcn.h is missing, but is available in "dlcompat"
    (See http://www.opendarwin.org/projects/dlcompat/)

5) socklen_t is *not* being defined by <sys/socket.h>

6) ldfuncs are all missing from System.dylib, and it
    seems that gphobos is "hardcoded" to assume them ?

Details are attached. (target is powerpc-apple-darwin6)


If the last issue can be resolved (a configure issue ?),
then it should be OK to run GDC on Mac OS X 10.2 too...

Mac OS X 10.1 only has GCC 2.95, so it's not for GDC.
Mac OS X 10.0 aka Mac OS X Public Beta 2, is obsolete.

PS.
A more exciting project is building X86 cross-compiler,
mostly for targeting Mac OS X 10.4 - running on Intel:

i686-apple-darwin8-gdc-4.0.1
powerpc-apple-darwin8-gdc-4.0.1

But so far I haven't had any luck cross-compiling that
either, and I don't have access to the Transition Kit.

Can you try this fix for the ldfuncs problem?  It's a replacement for 
d/phobos/configure (also includes the configure.in)

http://home.earthlink.net/~dvdfrdmn/d/macosx102compat.tgz

I don't have a working 10.2 system right now (my iBook is giving off 
toxic fumes...)

The next release I make will be on SourceForge.  At that time, I'll put 
all of new cross-compilation stuff in CVS.

Sounds good! (too bad SourceForge doesn't have any "newer"
Mac OS X machines in their build farm, like any Mac OS x86)

Q: Did you have any input on how to tweak the "configure"
for Mac OS X 10.2 that didn't seem to have the ldfuncs ?

Yep, here is a replacement for d/phobos/configure:

http://home.earthlink.net/~dvdfrdmn/d/macosx102compat.tgz

I don't have 10.2 system to test it, though.  If it works for you, I'll 
put it in the next release.

Thanks,
I'll give it a spin (or more of a "slow rotation", at 500Mhz)


If it works, I'll do the same thing for the "gdcmac" binaries.

Mac OS X 10.2 and GCC 3.3 will be the minimum, though.

There are limits on how far through the layers even
an archelogically interested person is willing to dig :-)

Closer...

ld: Undefined symbols:
_strtold

So just that one left now. :-)


Might be from std.c.stdlib ? Looks duplicated:

version (darwin)
{
     private import std.c.darwin.ldblcompat;
     real strtold(char *, char **); 
pragma(GNU_asm,strtold,"strtold"~__DARWIN_LDBL_COMPAT);
}
else
{
     private import gcc.config;
     alias gcc.config.cstrtold strtold;
}

Try replacing that fragment with this one:

-----
version (darwin)
     version (GNU_Have_strtold)
	version = darwin_strtold;
version (darwin_strtold)
{
     private import std.c.darwin.ldblcompat;
     real strtold(char *, char **); 
pragma(GNU_asm,strtold,"strtold"~__DARWIN_LDBL_COMPAT);
}
else
{
     private import gcc.config;
     alias gcc.config.cstrtold strtold;
}
-----


Thanks for putting up with all of this!

Okay, will use this new code instead.

Np, seems to be complete for this time.

Yeah, that was it... And D "Hello, World!" now works :-D


Changed to:

version (darwin)
{
     private import std.c.darwin.ldblcompat;
}
else
{
     private import gcc.config;
}
alias gcc.config.cstrtold strtold;


gdc-0.17-mac-10.2 going up as soon as packaging completes.
