Perfect, you were right! This solved the problem 😀 The 3dfx tests worked perfectly, I'll test some games too and give some feedback. Thanks a lot for your great work!

Yes, with glide disabled dosbox works just fine, so it surely is a problem in the glide initialization somewhere...

I just did it, you can find the output in the attached file. Running through Valgrind doesn't make dosbox crash (as the dosbox --enable-debug did). However, trying one of the 3dfx tests freezes dosbox. My guess is the problem starts here: ==14936== Invalid write of size 4 ==14936== at 0x80EC8CB: …

Investigating the issues another bit, I found out a line where the problem might be. The backtrace reports: (gdb) bt #0 0x00ceff5c in malloc_consolidate () from /lib/libc.so.6 #1 0x00cf20bd in _int_malloc () from /lib/libc.so.6 #2 0x00cf3ebe in malloc () from /lib/libc.so.6 #3 0x07a42557 in operator …

Hi Moe, it's a 32-bit build, in a Fedora 7 OS. Let me know if there's anything I can do to help you sort out the problem.

I recompiled disabling the debug, and dosbox crashes again on startup... it looks like debug mode made it more fault tolerant. 😕

Just tried recompiling with your new patch, and now it compiles fine without having to touch anything. I also added --enable-debug to see if it gave me more info about the crash. However, now it didn't crash at all! So I made a few tests: The 3dfx diagnostic kit tests worked fine; Tomb Raider also …

Yes, this is the exact error it gives me when compiling with 4.1: if g++ -DHAVE_CONFIG_H -I. -I. -I../.. -I../../include -I/usr/include/SDL -D_GNU_SOURCE=1 -D_REENTRANT -g -O2 -MT file.o -MD -MP -MF ".deps/file.Tpo" -c -o file.o file.cpp; \ then mv -f ".deps/file.Tpo" ".deps/file.Po"; else rm -f ". …

I managed to turn around the compilation problems this way: 1) I forced the defines of FX_ENTRY and FX_CALL to #define FX_ENTRY extern #define FX_CALL in sdk2_3dfx.h, because otherwise it kept introducing __stdcall which doesn't exist in Linux; 2) I didn't notice the mixxing bracket at line 204, …

Hi, I just tried the patch on Linux, but it fails when compiling glide.cpp: g++ -DHAVE_CONFIG_H -I. -I../.. -I../../include -I/usr/include/SDL -D_GNU_SOURCE=1 -D_REENTRANT -g -O2 -MT glide.o -MD -MP -MF .deps/glide.Tpo -c -o glide.o glide.cpp ../../include/sdk2_glide.h:53: error: expected `)' before …

Sorry, I missed your other post with the glide patch... ignore this message, I'll try that one 😀

Hi, sorry for my late answer, I missed your reply... thanks for releasing your sources! I just finished compiling your latest CVS, dated 23-06-07. In order to be of help to others who might want to accomplish this under linux, I had to make the following things before: 1) I removed any reference to …

Let's hope you're right, considering I have an nvidia 🙄 Let me know if there's any way I can be of help in debugging this problem...

I just tried the patch, and there are two results: 1) now I can see the static background image while loading the scene after the videos, which was missing before; 2) but after the loading process, I just see a pink block! nothing else... even if I can hear the game running in the background ( …

I read about the low cycles when loading in some old discussions about Redguard. However, I didn't need to do it, I left cycles=auto and just had to set the memsize to a high value (I've chosen 64 MB) and all went fine. All the intro videos play well, while the game, even if good looking, is really …

Wow works like a charm, thank you! It took me a while to understand that I needed the CVS version of openglide (the zips on the site are old and no Makefile in them), but then I managed to compile the SDL version as you suggested. The 3dfxdiagnostic tests work fine,but they freeze dosbox when …

Hi gulikoza, thanks a lot for your quick answer! I'll try following your suggestion, and I'll keep you updated on the results in a later reply.

Hi all, I searched the whole forum to see if this subject has already been discussed, but I couldn't find anything explicitely related. I'm trying the Linux build of ykhwong's Dosbox CVS, since I'm interested in its Glide functionality. The game I'm experimenting with is Tomb Raider, since it should …
