It's actually most easy in the alpha, since it comes with both
toolchains already (or you can install the other GCC from the optional
package if you don't already have it).
Navigate to Haiku checkout:
cd <haiku trunk>
Create output directories for both:
mkdir generated.gcc2
mkdir generated.gcc4
Configure GCC4 side by supplying the cross tools prefix (note that the
cross tools prefix includes the ending slash, so don't omit it, the
second line is all in one line):
cd ../generated.gcc4
../configure --alternative-gcc-output-dir ../generated.gcc2 --cross-
tools-prefix /boot/develop/abi/x86/gcc4/tools/current/bin/
Configure GCC2 side:
cd ../generated.gcc2
../configure --alternative-gcc-output-dir ../generated.gcc4
Build hybrid:
jam haiku-image
If you build in generated.gcc2 you'll build a GCC2/4 hybrid, if you
build in generated.gcc4 you'll build a GCC4/2 hybrid. It's as easy as
that really. If your default GCC is GCC4 instead of GCC2 you just supply
the corresponding cross tools prefix on the other directory. In fact
you can also provide it explicitly for both directories then it
wouldn't matter which one is currently set as default.
