Thanks Guys for the Quick reply, I appreciate it.

So currently the Suse contributed fork uses 32bit system calls inside the 64bit binary anyway. So there will be no issue using a default cdrecord branch which now has dvd-/+ support, compiled as a i386 arch?? (Sorry for my lay understanding,) I'm a build monkey not a coder ;-)

Joerg, considering the explanations bellow, adding in x86_64 include definitions to your cdrecord make system wouldn't be too difficult then?? Always helps for people like me who tend to extract, readme, make, make install, and I prefer to have 64bit binarys where possible (even if they are making 32bit calls underneath... just cleaner that way =-).

Again thanks both of you, both your comments will hopefully stop wasting the relatively expensive dvd media my burner has been devouring.

Kind regards

An 32bit version of cdrecord should work on x86-64 in theory.

Correct for Solaris, not correct for Linux because of missing 64/32 bit support in the drivers :-(

You are wrong on this. We have pretty good 32bit emulation including most ioctls since many years (99+% coverage). In fact there are whole 64bit ports who usually run 32bit programs and 64bit only in special cases (like sparc64 or ppc64).

Things that need to be planned take a long time on Linux. Solaris offers full 64/34 bit support since 1997, let's see when Linux will come up with it....

The earliest copyrights in the 32bit emulation code of Linux (for sparc32/sparc64) date back to 1997 too.

The x86-64 32bit emulation is only a few years old, but builds heavily on the work of other architectures who do this much longer and is also quite mature.
