The only simple solution I know is to use .so. The problem of exposing too many functions will then disappear, but the problem of the lib calling to the dosemu functions instead of its own functions with the same name, will remain unless you use the -Bsymbolic option of the linker. As to solving this without .so, I don't know. Maybe someone else does.

Yes! So, as I understand, vde allows you to build a userspace network of any kind. First thing you do is to connect to vde_switch. This is with libvdeplug. Then, by the use of some control interface (by sending a textual commands, they are listed in their docs), you create an instance of vdeslirp and connect it to the same vde_switch. So it may be a very interesting framework after all. ------------------------------------------------------------------------------ This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev _______________________________________________ Dosemu-devel mailing list Dosemu-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/dosemu-devel
