Hi List I'm finally on my ass trying to redo the ATL/MFC Job from a year ago. This time I decided to start on windows with MinGW than move the MinGW makefiles to be used with winegcc. It is a grate test for winegcc and the windows API in general. Well it turns out to be a very big test for MinGW as well. The headers are in a very bad shape. I had to use Wine headers to be able to compile. but I'll leave all that to a later e-mail.
[Q] I'm (well ATL is) using __attribute__((weak)) (translated from __declspec( selectany) ) for instantiation of members and variables in headers. I had no problem with it On GCC in Linux (gcc 3.2.2). On MinGW I get below warning. And needless to say that I get a Linker duplicate symbol Error. Any Ideas on how to overcome this. Is this a g++ only bug?
<g++ warning example> H:\Dinosaur\OneSource\MinGWStudio\msvc\atl\include\atlhost.h:56: warning: weak declaration of `UINT ATL::WM_ATLGETCONTROL' not supported </g++ warrning example>
<linker error example> H:\Dinosaur\OneSource\MinGWStudio\msvc\atl\include\atlwin.h: multiple definition of `ATL::WM_ATLGETCONTROL' H:\Dinosaur\OneSource\MinGWStudio\Samples\AtlWB\Debug\aboutdlg.o(.bss+0x1c):H:\Dinosaur\OneSource\MinGWStudio\msvc\atl\include\atlwin.h: first defined here </linker error example>
Please forgive me for sending it here and not to MinGW list. But I feel more at home here than there. ( :( )
