ttlanhil Report post Posted July 8, 2005 I can get cal3d to compile (I use visual studios)... that's easy enough. takes some modifications to ELC tog et that to compile, and then it still dun run right. maybe someone can spot my mistake okay, all changes from CVS: I copied the sources from cal3d into a dir called cal3d commented out print_sound_objects() in gamewin.c (only a problem in debug, but it won't compile at all otherwise) mkeysort.c: visual studios chucked a fruity sbout the inline int min. removing the inline part makes it compile, but I kinda worry about this global.h: the __inline def for VC at this stage, trying to compile will come up with a number of "function already defined in cal3d_wrapper.obj" results... if I #ifdef comment those out from cal3d_wrapper.cpp (leaving 5) then it builds. so then I can try to run it, and I get the following: "Unhandled exception at 0x05e58384 in elc-d.exe: 0xC0000005: Access violation reading location 0x00000024." VC gives the following backtrace: cal3d.dll!05e58384() > elc-d.exe!CalCoreSkeleton_Scale(CalCoreSkeleton * self=0x00000000, float factor=1.0000000) Line 534 + 0xf elc-d.exe!parse_actor_script(_xmlNode * cfg=0x0ee77fc0) Line 1954 + 0x1c elc-d.exe!parse_actor_defs(_xmlNode * node=0x0ee6aef0) Line 1970 + 0x9 elc-d.exe!parse_actor_defs(_xmlNode * node=0x0ee6c878) Line 1976 + 0xc elc-d.exe!read_actor_defs(const char * dir=0x0012fac4, const char * index=0x004f08e8) Line 2008 + 0x9 elc-d.exe!init_actor_defs() Line 2029 + 0x10 elc-d.exe!init_stuff() Line 522 elc-d.exe!Main(int argc=3, char * * argv=0x0ed55ac0) Line 147 elc-d.exe!WinMain(HINSTANCE__ * hInst=0x00400000, HINSTANCE__ * hPrev=0x00000000, char * lpCmd=0x00141f0b, int nShow=1) Line 203 + 0xd elc-d.exe!WinMainCRTStartup() Line 390 + 0x39 kernel32.dll!7c816d4f() ntdll.dll!7c915b4f() kernel32.dll!7c8399f3() and points to line 534 of cal3d_wrapper.cpp (remember the #ifdefs will put this slightly off): in function `CalCoreSkeleton_Scale', the command `self->scale(factor);' trying to continue doesn't go forwards, it goes back to that same error again. same numbers in the error message too. I've tried this with several versions of cal3d.dll (one I made, one that was in 1.0.2test2.zip, one that was in cal3d' download of binary viewers). no help anyone know what I've done wrong?

ttlanhil Report post Posted July 8, 2005 I'll try to explain a bit more what I think is happening, in case it points to a problem/bad asumption the problem is that there's two projects using cal3d_wrapper.cpp. the one in ELC has had about 5 functions added to what was copied from cal3d itself. so the cal3d lib has all except those extra 5 already, and when ELC tries to link against cal3d.lib, it finds that there are function with the same name both in the cal3d.lib and the cal3d_wrapper.obj (which was just made) this is why I tried trimming out all of the functions that are done twice, and while this does get it to compile, it won't run. calls to cal3d.dll result in an error (I'm asuming what's in cal3d.dll should be similar in intent to cal3d.lib... they're made at the same time) removing cal3d_wrapper.cpp from the cal3d library project gets the same results. also, I'm pretty sure that the dll is not the problem, at least not alone, since using copies from other source results the same. does it sound like my logic is skewiff, and I've taken a wrong path? or does the fact that both have the same file mean I got a wrong version or tried to use it the wrong way? anyone else got cal3d up and running using VC++?

mikeman Report post Posted July 8, 2005 ttlanhil: cal3d_wrapper.cpp are NOT to be built with ELC. This is what you should do: 1)In Cal3D, substitute the cal3d_Wrapper.cpp and cal3d_wrapper.h files with the ones I gave you. 2)Compile Cal3d, getting cal3d.dll and cal3d.lib 3)Compile ELC(without including cal3d_wrapper.cpp in the build) and link with the cal3d.lib you just created. You'll get the .exe 4)Put the cal3d.dll you created in the same folder as the .exe, and run the .exe. It should work. Share this post Link to post Share on other sites
Learner Report post Posted July 8, 2005 you really should try to make sure that no changes are needed to the cal3d library. How about a wrapper that only has your custom functions? As it is, I got it working under Dev-cpp with the wrapper in both and linking in the cal3d as a dll without any problems now. Only change I made in cal3d was in platform.h to help it build the .dll Share this post Link to post Share on other sites

mikeman Report post Posted July 8, 2005 (edited) ttlanhil: That problem doesn't have to do with compiling correctly, the program is failing to find and load a skeleton file. Do you have setup all the files correctly(actor_defs,Meshes,Animations,Skeletons)... Ok, it seems I've managed to sort things out here, and I'll take Learner's advice, don't mess with Cal3D source, just build a mini lib that has only the extra functions I need. I advice you all to stop trying for a while until I fix all this, and I'll post my progress soon. Edited July 8, 2005 by mikeman Share this post Link to post Share on other sites
Cajs Report post Posted July 8, 2005 (edited) FYI - got it compiling on VS (2k3 version) wihtout modifications to any files (other than the project files to add linker libs etc.) How I did it: Start with pre-cal3d solution file so I woun't go in to setting up SDL/OpenGL etc. libs.... 1) I downloaded cal3d from here -> http://prdownloads.sourceforge.net/cal3d/c...tar.gz?download 2) extracted somewhere / run the included dsw file / upgrade it to VS 2K3 format (and delete all the non-existing projects that are in it but not included in the download) save it / close 3) take cal3d_wrapper.cpp and cal3d_wrapper.h from the client cvs and replace the 2 files in cal3d ditribution wiht them (these are in \cal3d-0.10.0\src\cal3d) 4) open the solution file you created in 2) and build it wihtout any changes - you get 3 files under \cal3d-0.10.0\bin\release (ofc if you building debug you get it under debug....) - cal3d.dll, cal3d.lib, cal3d.exp 5) copy cal3d.dll to your EL folder 6) open the EL Client solution file and go to elc project properties -> C++ / General options and add C:\Projects\ELClient\SDK\cal3d-0.10.0\src (or where ever your cal3d is) to additional include directories, next go to linker -> general options and add C:\Projects\ELClient\SDK\cal3d-0.10.0\bin\release to there, next in linker-> input -> additional dependencies add cal3d.lib, apply / ok 7) try to build - at this point I tried building the client and got one more linker error that I traced down to gluProject in lights.c -> go back to project properies linker-> input -> additional dependencies add Glu32.lib (I'm listing this separatly since it is possible your OpenGL files might have this function and you might not have to link against Glu32.lib at all, glu32.lib is probably part of the MS platform SDK so youm ight have to install that if you don;t have it) 8) get the package with meshes/textures etc. Wytter posted ( http://el.tfm.ro/update_1.0.2-test2.tar.bz2) and put that in to yuor EL client directory (back it up first...!), put the compiled exe in to it run it! That's it...seems to work evne tho my average FPS seems to have dropped by 8-10 (70 -> 60) and IP has no snow /server thinks its a differnt map so cna get a bit werid there... ~C Edited July 8, 2005 by Cajs Share this post Link to post Share on other sites

I put a copy http://ttlanhil.tripod.com/EL/win_cal_err_log.txt here. there seems to be some stuff missing, though I don't think they're skeletons IP has no snow /server thinks its a differnt map so cna get a bit werid there...~C 177858[/snapback] it is a different map. the one for 1.0.2 as in another thread. go back to the old copy if you want to be able to use it for now 8^) 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. Share this post Link to post Share on other sites

Wytter Report post Posted July 8, 2005 We could also just add a note on top of the cal3d_wrapper.cpp saying that it's limited to the ELC project, and only holds a few more necissary functions. On another note, I noticed that we could set the LOD for each actor... I was thinking about setting the LOD to be lower on low-end computers (using poor_man). Will that be feasible?
