Hello, I work with libraries with lots of templates and, to reduce compilation time, I split long definitions in separate files, and I do explicit template instantiations in an extra compilation unit. This used to work fine until (and including) gcc 3.4, but broke in gcc 4. You can find a small example code at: http://www.enricozini.org/store/testcase.tar.gz In that example, if I remove the #pragmas, it works. With the pragmas, it complains about the default constructor, destructor, copy constructor and copy operation are used but not defined. I didn't find this behaviour documented in the gcc changes files, and I can't understand if it's a problem in my code or a problem in gcc. I'm this writing for help. Please keep me Cc-ed as I'm not subscribed to the list. Ciao, Enrico -- GPG key: 1024D/797EBFAB 2000-12-05 Enrico Zini <enrico@xxxxxxxxxx>
