1. Some corrections and hints: in the SDL script the only important things are ./configure --enable-static --disable-video-x11 --without-x --prefix=/path/for/SDL/binaries all other things will get enabled by default anyway (so your builds *DO* have joystick and CD-Rom support), I just let it enable …

Everything in this post was worked out by Dominus, not by me, but I thought it might be useful to put all the details together in one place. Here how to build a standalone version of DOSBox SVN using the revised SDL 1.2 code that works correctly under Lion. This assumes that you already have DOSBox …

Well, after begging for help in building a standalone DOSBox for OS X, with the latest SDL, I seem to have succeeded in doing exactly that. It was dumb luck, not skill, that did it, and I probably did it in the stupidest possible way. Here's what I did. In the makefile in the top-level directory and …

I'm sorry to report more trouble. Dominus, the instructions you gave me worked perfectly to build DOSBox with the new SDL, but the resulting executable was dynamically linked to the SDL dynlib. I have spent the past few hours trying to use your old instructions to build a standalone excecutable, but …

hmm, it *IS* slower but for me only a fraction (ha ha) and with cycles set to max it is way faster of course :)) Another question about this. I downloaded the current SDL again, reverted the change in which you discovered the error, and built SDL and DOSBox again. This time, I find that even with …

I'll test later today if I find time.

First, your reversion worked perfectly. Now I can build DOSBox without getting the white-window-of-despair when I switch to full-screen. Unfortunately, it's still very slow. Here's one way to use Fractint to test speed. I'll spell out every detail (you won't need all the details, of course) in case …

hmm, I got the same result with the white screen with current SDL dev code. Try the snapshot download from the 5th of August from their download page whether that also has the slowness (it doesn't have the whiteness of death :)) I know I asked in another thread but how do I check for the slowness? …

Here are some more details. Following what you said in an earlier message about building SDL with the same exports that I had been using to build DOSBox, I've been using this script to build the new SDL: #!/bin/sh export CFLAGS='-I/opt/local/include -O2 -arch i386' ## export CXXFLAGS=$CFLAGS export …

Thank you again - I hope this isn't the kind of problem that only shows up on my system. The difference in speed is fairly spectacular. With the system that I built using your instructions earlier this year, WordPerfect 5.1, running in full-screen mode, switches from text mode to graphic-mode print …

Trouble, alas. The new version is so slow in graphic mode that it is almost completely unusable. Is this the effect of the new SDL version, or is there anything that can be done to fix it? I don't expect that there is any easy answer to this. Thank you again.

You are amazing - I simply saved your commands as a script, chmod-ed it, ran it - and got a perfect executable that goes to full-screen flawlessly. Thank you a thousand times!
