manually building Dosbox CVS in 32-bit

[Dominik Reichardt]

Hi all,

I'm wondering how to build Dosbox CVS in 32-bit. If I edit the port  
file of dosbox by adding

if {$build_arch == "x86_64"} {
     configure.build_arch i386
} elseif {$build_arch == "ppc64"} {
     configure.build_arch ppc
}
if {[variant_isset universal] && [string match *64* $universal_archs]} {
     pre-fetch {
         return -code error "$name $version cannot be built for 64-bit  
architectures"
     }
}


and commenting out

#platform darwin {
#    configure.args-append --build=${build_arch}-apple-darwin${os.major}
#}

stopping the port install process in configuring and then overwriting  
the 0.73 release source with the CVS and then starting port install  
dosbox again, I am able to build a 32-bit Dosbox CVS that is stable  
and doesn't crash when switching to dynamic core (like the 64-bit  
version properly built by MacPorts does).

So that is working by tricking MacPort but I'm wondering how to do  
that manually.

I've tried with configuring dosbox with
./configure -build=i386-apple-darwin10.0.0 --target=i386-apple- 
darwin10 --prefix=/opt/local --disable-sdltest --disable-alsatest
but that didn't work and has the same compile errors that the MacPorts  
port had before the last patch. So I'm obviously missing something  
that MacPorts does right when I use the above trick to build Dosbox in  
32-bit.
What is it? Can anyone help me?

P.S.: Dosbox CVS still needs the midi_coreaudio.h patch that MacPorts  
does and in src/hardware/serialport/libserial.cpp you need to exchange  
#include <malloc.h> with #include <stdlib.h> (line 260) - just as an  
help to anyone trying their hand on the cvs as well. I've reported  
both issues to the Dosbox developers.
