[openbeos] Re: __declspec and static libraries

AFAIK the __declspec stuff has no effect on BeOS and Haiku (at least with
gcc 2.95.3).


The BeBook doesn't seem to agree with you :-)
Look: http://www.beunited.org/bebook/The%20Kernel%20Kit/ImageConcepts.html
This is a left over from the PPC compiler. With ELF/GCC, all symbols are automatically exported by default. 


And does anyone know if using autotools and libtool one should define
AC_LIBTOOL_WIN32_DLL on BeOS/Haiku too?

I've no clue what this is, but it doesn't sound right.


Well, basically the __declspec stuff is the same you find on windows,
and the autoconf manual suggests using that macro.
Again, it was a left over from the mwcc compiler. You don need that with GCC on Haiku or BeOS. 


I've done without it, but had to pass -no-undefined to libtool,
otherwise the shared library wouldn't build (inter-library
dependences).
Yes, that is expected. Under BeOS (and I guess haiku too) all symbols must be defined at linking time. It has nothing to do with the __declspec() stuff.
