Pull & update hg again. It's being worked on atm, seemingly to get a new 1.2 release out.
And try a
Make distclean
(don't know whether that is available in SDL makefile but if it is it might help.
Or/and try to get rid of everything that is not from hg in that folder.

Tip of 1.2 branch compiled fine for me in 32bit on lion with xcode 4.2.1

Success: thank you. Make distclean didn't help, so I created a new folder, pulled the current repository into it, copied my build-script (see message above) into the new folder, and all worked perfectly. Thank you again.

Glad it solved so easy. Always helps if one knows that the problem is on your side and not the sources 😉
We should search for a mac programming/development novice forum somewhere so our off topic discussions are better suited 😉
(don't get me wrong our mac developer discussions proved friuitful for me as well)

I've been looking for exactly that kind of forum, but haven't found it. I spend a lot of time at http://www.emaculation.com/forum/ but that's devoted to SheepShaver and BasiliskII, and I haven't found any good reason to try to build either of them. (I maintain an AppleScript application that runs WordPerfect for the Mac in more or less the same way I run DOSBox under an AppleScript application, but the builds created by the moderators at the emaculation.com site do the job perfectly well.)

Is any chance that the moderators here might create separate sub-forums for development on specific platforms (OS X, Linux, "other platforms")? That way, we wouldn't clutter up this forum with threads that are of no interest to anyone on a non-OS X platform.

I've now tried to build SDL 1.2 under Mountain Lion, still using the script that I got from Dominus in the first message. No luck, I'm afraid. I tried removing the "-4.2" string from each export. That didn't help either. If anyone has any suggestions for building SDL 1.2 for use with DOSBox under OS X, I would be very grateful.

Works for me. This is the easy build way, which makes both 32 and 64bit builds against SDK 10.8. Only problematic thing is that X11 is not available in the old default locations anymore since Apple is not using it anymore and advises people to install xquartz instead. Hence the disable x11 stuff.

To make it compatible with older Mac OS X versions, I advise to have the old SDKs around and build 32bit against the 10.5 SDK and 64bit against the 10.6 SDK.
If you want to build for PPC you need the old Xcode 3.2x around somewhere since you need its gcc.

Good luck. Make sure you use a clean source and best use the hg of SDL 1.2 branch.

Edit: for ppc you need to pass host to the configure step.
Edit 2: I needed to correct some ' '...
Edit 3: I accidently left the gcc and g++ for ppc out... 😀
Edit 4: tested all this out and all three arches built correctly for me using this way.

Thank you for this - but, unfortunately, I get an error message about "windres":

configure: error:
*** When building from Mercurial you should configure and build in a
separate directory so you don't clobber SDL_config.h, SDL_revision.h

I think windres involves checking for Windows resources. Do you have any idea of how I ended up with this problem? Apologies for bothering you with my own problems!

Look in config.log for the real error/failure. Something is probably wrong with the source (are you using latest SDL 1.2 branch ?) or you might have something in your .profile that screws things up.
Please check these thingsand then start a new terminal (quit and start terminal, not close and start terminal) and only do the easy 64bit building of sdl. Copy paste your whole terminal and attach config.log.

Oh and make sure that in xcode 4.4.1 preferences you download/install the unix development tools.

Edit, just checked and windrws=no message is normal. So you definitely need to check config.log. The message to build outside of the source really makes me think you are trying to build SDL trunk (SDL 2) and not the SDL 1.2 branch.

Edit 2: just chekced the message you see is from running configure with SDL trunk. Check the ReadMe, it says SDL 2.0 at the top you are trying to build the wrong SDL 😀

That explains it! I thought I was pulling source from SDL 1.2, but obviously wasn't. Will begin again - and many thanks for your patient help with this!

Of course you were right - thank you yet again.

I couldn't figure out how to use MacHG to pull source for 1.2 from the SDL repository, so I downloaded the 1.2.15 code from here:

http://www.libsdl.org/download-1.2.php

If you know the string to use in MacHG to download the current state of the 1.2 branch, I'd be very grateful. Everything I've tried ends up either with a "non found" message or it downloads 2.0. I know this is a beginner's error, but I'm still baffled by it.

EDIT: OK - I figured out how to use MacHG to download a specific branch. In the Clone dialog, choose Advanced Options, and then clone the specific branch SDL-1.2. And, again following your instructions, I successfully built DOSBox from the latest SDL and the latest DOSBox SVN. Thank you!!!

You're welcome 😉

I just used command line mercurial following the instructions on the SDL page, I think (it's bern a while).

As for SDL 2.0 don't even use that when the SDL guys finally release something, Dosbox is not compatible to it.

I tried that, using the command-line mercurial downloaded from the same site as MacHg, but got error messages. But MacHg worked when I figured out the advanced option. (Unfortunately, I can't make that advanced option "stick" so I'll need to enter it every time I update, in order to avoid downloading 2.0.

I noticed that you're very active over at MacScripter.net. See you there!

It should be enough to "hg pull && hg update". This should stick but then I'm not really an expert on mercurial...
I'm not really active there, it's just where I look for help when I'm stuck at dome script once a year 😉
