Hello there,

I can't, for the love of me, generate a 32bits executable on osx (Snow Leopard, 10.6.8 ). This is what I'm trying. First, the exports:

1export CFLAGS='-I/usr/local/include -O2 -arch i386'
2export CXXFLAGS=$CFLAGS
3export CPPFLAGS=$CXXFLAGS
4export LDFLAGS='-L/usr/local/lib -O2 -arch i386'
5export CC='/usr/bin/gcc-4.2 -arch i386'
6export CXX='/usr/bin/g++-4.2 -arch i386'
7export GCOV='/usr/bin/gcov-4.2 -arch i386'

(yes, libsdl was installed from sources in /usr/local, no macports used)

then I run ./autogen.sh in the sources root directory.
Next I run ./configure. No errors at all. But I get the following errors during the compilation process:

Is sdl in 32 bit?
And which SDL did you compile and which Dosbox are you trying? Version, I mean

Try my instructions in the message in this thread, dated 2011-1-06 @ 04:00 am, and let us know what happens.

@Dominus: SDL is in 64bits, that could be the problem. I compiled and installed 1.2.14 sources.
I'm trying to build the trunk in cvs (cloned yesterday).

@emendelson: I got the exports from your instructions, and I also run a make clean, the autogen.sh script and the configure script.

So, what are my options? Building a new, 32bit SDL and install it to another location, then pointing dosbox to it via the exports with the new routes?

If you compile SDL from trunk you need the 1.2 branch but that currently breaks fullscreen/windows.

You can also compile in 32bit and lipo the libs together so they are universal

Compiled SDL 1.2.14 from the tar.gz in the libsdl page, in 32bits. I have compiled this version on Linux countless times, and also compiled dosbox against it, with no problems at all.

Installed it in /usr/local32 via configure --prefix.
Pointed dosbox sources to the new 32bits sdl with the exports:

export CFLAGS='-I/usr/local32/include -O2 -arch i386'
export CXXFLAGS=$CFLAGS
export CPPFLAGS=$CXXFLAGS
export LDFLAGS='-L/usr/local32/lib -O2 -arch i386'
export CC='/usr/bin/gcc-4.2 -arch i386'
export CXX='/usr/bin/g++-4.2 -arch i386'
export GCOV='/usr/bin/gcov-4.2 -arch i386'

ran make distclean.
ran autogen.sh after it.
ran ./configure --build=i386-apple-darwin10.5.0 --host=i386-apple-darwin10.5.0, because if I don't include the build and host options, it detects a 64bits building system.

But dosbox gives the same errorrs on compilation...

Use the sdl-prefix option in dosbox configure as well. But strange that you need to pass build and host, never needed this on SL?

On page 2 of this thread I ran into this as well but didn't need it anymore after passing along the correct includes.

1cast from ‘Bit32u*’ to ‘Bit32u’ loses precision

So it assumes that a pointer is more than 32 bits. Can you post/attach the config.log file and maybe the makefile present in the directory src ?

Shouldn't there be a -m32 somewhere in between?

it still thinks it is compiling for 64bit.

@Dominus: then I'd be more than happy to know how to tell it to compile for 64bits, it's very stubbon 😁

As gulikoza said try adding -m32 to your CFLAGS and re-export all flags.

And use a really clean dosbox (i'm not trusting distclean 100%). M32 shouldn't be needed on os x.

Tried a new fresh copy of the trunk sources, exported the new CFLAGS including -m32, ran autogen.sh, configure with the sdl prefix and all, and still no luck. The same exact errors on building.

this is really strange then. I just tried myself and cannot ever reproduce this.
is your ~/.profile clean?

in your config log, it seems your gcc isn't passing along the "-arch i386" flag.
Can you do the exact exports I gave earlier and attach the config.log again?

Edit: as I wrote on page 2 of this thread host/build'/target are determined partyl by the compiler flags. if you don't pass the arch to the compiler binaries, averything is reset to the 64bit host. Probably not everything, hence the compiler error.

another odditiy, your makefile reports automake 1.11. I'm on Xcode 4.2 Preview 7 and it still comes with automake 1.10.
Where does that come from? Did you muck with Apple's development stuff? You shouldn't do that since Apple does some patching to a lot of things. Better restore it to Apple's stuff and if you want to use newer versions make your own prefix and place that bin in front of the PATH setting.

I haven't mocked Apple's binaries, but installed automake/autoconf/libtool etc in a separate directory: Apple's binaries live in /usr/bin while mine live in /usr/local/bin. So I removed /usr/local from my /etc/paths and now I'm on Apple's default tools again, with the versions you would expect.

But I get the same error. Take a look at the updated config.log, I think it says it's configured for a i386 cpu:
