Some MacOSX build related questions

Some MacOSX build related questions

[CHENG Gao]

1) In nextstep/README, it states MacOSX supported are 10.4 and up.
I suppose this is official. (It must be)

2) Considering 1), some code that checks MAC_OS_X_VERSION > 1030 or <
1040  or even < 1020 seems not necessary anymore. 

3) For same reason, is MAC_OS_X_VERSION_MAX_ALLOWED >=
MAC_OS_X_VERSION_10_4 check necessary anymore?

4) MAC_OS_X_VERSION_10_x (3, 4, 5, 6 at present) are defined in nsterm.h
and some other files. Is it necessary? Is it enough as nsgui.h does? (as below)

,----
| #ifdef NS_IMPL_COCOA
| #include <AvailabilityMacros.h>
| #endif /* NS_IMPL_COCOA */
`----

5) In nsimage.m, it has 'onTiger' check (defined in nsterm.h). If
official support version is 10.4 (Tiger) and up, this seems not
necessary anymore.

Yes.

You are probably right here.  The decision to terminate Panther support
was made officially, but the code was never updated to clean out that
support.  In addition to the macros you point out, I believe there are
some code blocks that can be removed.

I am not sure on this one.

Yes, see above.


thanks,

I guess so.

No, but nobody has taken the time to clean it up.

Same answer as above.

No, this is not enough.  For example, MAC_OS_X_VERSION_10_6 is not defined on OSX 10.4, but we use it in the source, so we must define it if not defined.
The define for MAC_OS_X_VERSION_10_6 in nsterm.m is redundant though.

I guess it is not, if indeed that function is available in Tiger and onwards.  But it might also mean that it is only available in Tiger and not in later versions.  I haven't checked.

Thanks for explanation. Now I understand.
