I recompiled with that switch, and uploaded a new dmd.1.040.zip. Can you 
give it a try, please?

You did add *both* the switches, right ? One for MDT, one for SDK.
(MDT is for choosing functions, SDK chooses headers and libraries)

-mmacosx-version-min=10.4 -isysroot /Developer/SDKs/MacOSX10.4u.sdk

It still fails on Mac OS X 10.4, maybe it still used native SDK ?
(if it matters, it gets a null dereference in _malloc_initialize)

Ok, I tried it with both switches now. Please give it a try.

No luck, same problem. Might want to add "requires Mac OS X 10.5"
or something for now ? Upgraded wxD CVS to support DMD on Mac too.

Yeah, that looks like the best strategy for the moment. It seems odd 
that there is such confusion about something that should be documented 
and straightforward.

If you specify a SDK for the compiler, you should also tell the linker 
to use the SDK.

	-syslibroot /Developer/SDKs/MacOSX10.4u.sdk

Or if you're passing the linker's argument through GCC instead of 
calling the linker directly:

	-Wl,-syslibroot,/Developer/SDKs/MacOSX10.4u.sdk

That's all explained in the document I linked to yesterday.


> (if it matters, it gets a null dereference in _malloc_initialize)

I made a diff of malloc.c (which contains _malloc_initialize) between 
10.4 and 10.5, and it looks like the rewrote half of that file, so 
there may be some differences.

But even then, if Walter is using the 10.5 SDK and isn't using anything 
specific to 10.5, I don't see where the problem could be comming from; 
especially after setting -mmacosx-version-min=10.4. When using the 10.5 
SDK, -mmacosx-version-min=10.4 will only make 10.5-only APIs 
weak-linked. When using the 10.4 SDK, it shoudn't do anything special, 
as 10.5's APIs are just not available.

I'd suggest to Walter to try adding the SDK flags to the linker. If 
that doesn't work, I'd suggest someone with 10.4 on an Intel Mac look 
for the crash report that should be in 
~/Library/Logs/CrashReporter/dmd_<date>.crash and send it to Walter, or 
post it somewhere for everyone to analyse.

I thought GCC 4.0.1 and later did that for you automatically ?
i.e. passed -syslibroot to the linker when using -isysroot

Must have been unlucky, or doing things "outside the dotted lines",
or both... Because usually it does just work with the MDT and SDK.

I think cross-compilation is rather transparent on Mac OS X, on the
other platforms it usually involves a full chroot or virtual machine ?

Hum, indeed, I think you're right. Seems like this Apple documentation 
is outdated: 
<http://developer.apple.com/documentation/developertools/conceptual/cross_development/Using/chapter_3_section_2.html#//apple_ref/doc/uid/20002000-1114311-BABGCAAB>

Sorry 

for the confusion.
