The problem with that seems to be that you can't predict what the host is. For example, I use both 32-bit and 64-bit hosts. And there have, in the past, been libc version problems between different linux distributions. > The "catch" is that, given that the binary is actually compiled for > x86, it will not run if installed on the device.

If we have to go down this route I think we need to find a different repository for this hacked cmake to live in. > So I ask other developers using cmake (I suppose there are not that > many, otherwise the problem would be reported sooner, given that cmake > + fremantle + ARMEL always segfaults): is it acceptable for you? I don't think there are many packages using cmake, but I think there are a few. There are two big problems I see: 1) There is not one host to build this for but several. And it has to be kept up to date or else we suddenly can't build some packages. 2) We also have to make it work in the autobuilder (how do you deal with that problem today?). > Note that this is in fact a qemu bug, but doing the compilation with > host-gcc/host-g++ did the trick and is easier than debugging qemu.

Could there be some way to use the actual host cmake instead of a special package? That would get round the problem of having to have different packages for different hosts. If so, maybe the package could set up the magic needed to invoke the host's cmake. Alternatively, any chance we could persuade the scratchbox developers to build scratchbox cmake packages along with the rest of scratchbox? They could then be provided along with the scratchbox packages for each different disrtibution.
