Hi Doug, We needed dynamic dll of Boost.Signals library and we fixed the dllimport/export problem. The attached files are context diffs (diff -u) against the current cvs state.

RE: [boost] boost_signals.dll contains no symbols
Hi Doug, Sorry, I forgot about these dependencies. Actually we are using the makefile where BOOST_SIGNALS_STATIC_LINK is defined. There is another related issue. We would like to have automatic library selection feature. This hides the details about which DLL to link to from the users (regex library does the same thing). For this reason we made header file and a few changes to include it. This header defines the naming scheme based on compiler options and contains the lib specifier (#pragma comment) that allows to pass the library name to the linker. Unfortunately, I don't know bjam well to build the libraries and DLLs which file names will correspond to chosen naming scheme. By the way the regex's Jamfile cannot produce the files corresponding to it's naming scheme. Maybe it is impossible in bjam system? If you want I send the header and the needed changes. AC.

I'm accustomed to Unix, where there is no notion of import/export and everything just magically works. Did you also have a Jamfile patch? I'm assuming that I need to define BOOST_SIGNALS_STATIC_LINK when building a static version of the library, but not define anything when building a dynamic version of the library (?).

Nothing is impossible ;-) In the case of regex it's possible as long as all the generated DLLs/SOs/LIBs have the name of the library in it: boost_regex. So the same applies to the signal library: boost_signals. You just need to find out what the mappings from the various build variants to the names, and use a stage rule to create the needed versions. The regex library already has a stage rule, for example, that generates a libboost_regex_debug.so, or boost_regex_debug.dll. So if you could tell us what the various names of the libraries that should be generated I can probably give you a stage rule that will generate them. Another alternative is to declare more targets (dll ...) with the specific names and options. If you want I send the header and the needed changes. Perhaps that might help. I guess the header would have the mappings from compiler to name. -- grafik - Don't Assume Anything -- [EMAIL PROTECTED] - [EMAIL PROTECTED] -- 102708583@icq ___ Unsubscribe other changes: http://lists.boost.org/mailman/listinfo.cgi/boost
