- I've just had a rapid response from NeXT on the above. The correct switch is
-
- cc -traditional-cpp
-
- which does correctly compile the code sample whilst still correctly locating
- the NeXT header files. This is documented in the NeXTSTEP 3.0 Release Notes.
-
- Mike Monegan from NeXT says:
-
- NeXT implemented a new version of cpp (cpp-precomp) for NS 3.0 to support
- precompiled headers. This is the default preprocessor, but
- unfortunately its
- behavior is not completely identical to the standard GNU cpp. In case
- of the
- above problem, an obscure bug fix to cpp-precomp was not released in
- NS 3.0 due
- to compiler stability concerns. Subsequent releases of NeXTSTEP will
- contain
- this fix. The temporary workaround is to use -traditional-cpp, which
- is
- documented in
- /NextLibrary/Documentation/NextDev/ReleaseNotes/Preprocessor.rtf,
- to get the old behavior (but without precompiled header support).
-
- I'd like to thank Paul Richardson and Mike Monegan from NeXT for their help
- in tracking this problem down and for pointing out the correct solution. I'd
- should also admit to not using the correct channels on this - that's what
- NeXTdeveloper support is for. Sorry about the wasted bandwidth.
