__declspec(dllexport) equivalent under linux / osx with g++ ?

[majestik666]

Hi,

i'm bulding a multi platform app under windows/linux/osx
an i have a bit of trouble exporting c++ symbols from
a dynamic library...
Under windows, i compile a dll exporting symbols
using :
__declspec(dllexport) & __declspec(dllimport)

I do export non-static and static members from my c++ code
without any problems ...
But I can't find a way to do it uner linux or osx with g++
anybody can help on this one ?

Thanks a lot
Francois

Ask in the news:comp.os.linux.development.* family. These things are
not part of the C++ language to start with, they are non-standard
platform specific extensions.

Or perhaps in the gnu.gcc.help newsgroup

I might be barking mad here but I believe, based upon my own experience
of porting a windows DLL to a linux shared library, that, with a shared
library, you don't have control over which symbols are exported from
the DLL.

I have, by the way, always preferred to use a .def file to declare the
exports from a DLL. I really dislike having to muck with function
signatures.
