Zep Report post Posted July 8, 2005 (edited) No, when I do that patch it doesn't export anything. Did you set any parameters? 177931[/snapback] strange, Learners patch works perfectly for me, I used that and the msvc importer, I also set dev-c++ to dll Edited July 8, 2005 by Zep Share this post Link to post Share on other sites

What I do is create a new blank DLL project, add all the .cpp files and tell it to compile, but it doesn't export anything. -EDIT: You have to use "Import-Import Visual C++ Project"? I haven't got experience with Dev-C, but I just saw that. -EDIT2: Ok, got it working. Edited July 8, 2005 by mikeman Share this post Link to post Share on other sites

Learner Report post Posted July 8, 2005 My current executable and dll for P3 and higher under windows is available at http://www.other-life.com/downloads/elc-cal3d.zip. One concern I have is whether or not my other development dlls (like SDL and ogg) are compatible with everyone elses. A developer file has been uploaded to http://www.other-life.com/downloads/elc-cal3d-dev.zip which will contain the .a and .dll bundled. My cal3d does NOT have the custom cal3d_wrapper in it, just the normal, so you still need to compile in the custom cal3d_wrapper. 177876[/snapback] And here is a low/older cpu version with sound disabled (some people don't have the same vorbis_d.dll I'm using) http://www.other-life.com/downloads/elc-P2-MMX.zip Share this post Link to post Share on other sites
mikeman Report post Posted July 8, 2005 Yes, I imported the VC project and made sure it was trying to make a .DLL. 177994[/snapback] Well, I did that, I edited platform.h as you said, and it still doesn't work. It exports some symbols, but not others(for example, nothing from CalMixer). I can't understand wtf is wrong. Share this post Link to post Share on other sites

duran Report post Posted July 8, 2005 oh duh... talk about screwing up. so mikeman, when will you be done with the new "wrapper"? Share this post Link to post Share on other sites
mikeman Report post Posted July 8, 2005 Well I did it, it all built fine and when I run the program it said it couldn't find the entry point for some function in CAL3D.dll! I just can't seem to be able to build Cal3D properly, there are a lot of functions that are in Learner's cal3d.def and not in mine. Anyway, I'll just assume you guys built Cal3D correctly with Dev-C. I'm really tired, I'll post the new wrapper tommorrow. It's no big deal though, just a .cpp with 6 functions. Share this post Link to post Share on other sites

mikeman Report post Posted July 9, 2005 Ok guys, I'm almost ready but I still haven't been able to build Cal3D with all the exports that are needed. However, I now know what's wrong so any Dev-C experts give me your advice. Specifically, I get no exports for the CalMixer class. That class is declared like any other: class CAL3D_API CalMixer { ..... } CAL3D_API is needed to export the classes, however CalMixer does not export at all. I saw that in model.h there is a forward declaration of it: ... class CalMixer; ... I changed that forward declaration into: .... class CAL3D_API CalMixer; ... and it exports it! And that happens for other classes that have forward declarations like this. What happens here? Do the forward declarations "override" the normal declarations? How can I fix that?

mikeman Report post Posted July 9, 2005 (edited) The most interesting thing is that, in some classes that are declared this way, only some functions are exported: those short functions that are defined inside the class declaration in the header file. Those that are defined in the .cpp file don't get exported! The whole thing must look something like this: ***Mixer.cpp***** #include "cal3d/error.h" #include "cal3d/mixer.h" --snippet from mixer.h:--- class CAL3D_API CalMixer { int foo(){return 0;}-->this gets exported void executeAction(...); } ------------------------------- #include "cal3d/coremodel.h" #include "cal3d/corebone.h" #include "cal3d/coreanimation.h" #include "cal3d/coretrack.h" #include "cal3d/corekeyframe.h" #include "cal3d/model.h"-->this has forward declaration: "class CalMixer"; #include "cal3d/skeleton.h" #include "cal3d/bone.h" #include "cal3d/animation.h" #include "cal3d/animation_action.h" #include "cal3d/animation_cycle.h" //This doesn't get exported because CalMixer was redeclared without CAL3D_API prefix! void CalMixer::executeAction(...){ } Weird. How are we going to solve this for all the users without heavily editing Cal3D sources? How did you get it to compile, I checked your .def files and they're all there. Maybe there is a global compile parameter or something that ignores re-definition of classes? Edited July 9, 2005 by mikeman Share this post Link to post Share on other sites
Entropy Report post Posted July 9, 2005 Mine compiled great originally, but it crashed at startup, somewhere in some windows DLL. I updated my DevCPP to the latest version, and then it didn't even compile, much less link. I felt like giving up, but then I asked learner for his caled_wrapper.o file, and now it works great.

duran Report post Posted July 9, 2005 (edited) In cal3d, the file platform.h at line 32, I changed it ti #if (defined(_WIN32) && !defined(__MINGW32__) && !defined(__CYGWIN__) ) || defined(__GNUWIN32__) To always allow creating the DLL exports id DLL is desired. From my checking, that is the only thing I changed in cal3d to fet it to compile & link properly. 177764[/snapback] hmm, no wonder i didnt get cal3d to work properly, missed the fact that learner both added a ( and ) around the original if statement and the || defined(__GNUWIN32__) stuff at the end. edit: still didnt help much tho. bombs out over those calgetmodel_getmixer and others...

duran Report post Posted July 10, 2005 hmm i fear that the latest version of devcpp have a flaw in the linking somewhere. ie, i killed the glu error by manualy adding libglu32 to the linker, and i got libcal3d to be about 500k in size by adding libstdc++ to it. only problem i have now is that it cant find the calmixer links. more or less the same problem that mikeman is showing...

duran Report post Posted July 10, 2005 hmm, i found some 3.4.2 gcc packages in dev-c++'s updater. and when adding those (and modifying the default compiler settings) i got dev-c++ to produce a nice, fat .a when compiling cal3d as a dll. still didnt get all the exports for some reason xP i wonder what happens if i tell it to compile the whole thing as an .a rather then a dll...

mikeman Report post Posted July 10, 2005 (edited) Wooo!! Ok, I FINALLY got it working. I don't know how it will work for all of you, but I had this idea this morning and it worked like a charm from the very first time. ****BUILDING THE CAL3D.DLL***** 1)You need to change that line in platform.h like Learner did 2)You need to do something similar in cal3d_wrapper.h 3)I've made a "decls.h" file and included it in every .cpp file Anyway, here are all the sources(and the .dev) that I used to build it: http://mman.tfm.ro/CAL3D_LIB.zip One note, I needed to copy all the .h files into my Dev-Cpp/Include/Cal3D dir because that's where it looks to find them. If all goes well, you'll get cal3d.dll and libcal3d.a ****BUILDING THE CAL3D_WRAPPER_ELC.DLL***** I've uploaded the .cpp and .dev file, just build it and make sure it links to libcal3d.a you just created before. http://mman.tfm.ro/CALWRAP_LIB.zip If all goes well, you'll get cal3d_wrapper_elc.dll and libcal3d_wrapper_elc.a ****BUILDING THE CLIENT***** There are some changes that I made in cal.c and cal.h. Here they are: http://mman.tfm.ro/ELC_UPDATE.zip Then, build the project and make sure that is linked to cal3d.a and libcal3d_wrapper_elc.a you created in the previous steps. If all goes well, you'll get the executable. Put it in the Eternal lands dir, alongside with the 2 .dlls we made, and run it.
