But in any case pkg-config is just reporting info from a data file, which doesn't necessarily correspond to what library .a and .so files are actually on the system. (It's your distro's packaging and dependency info that's responsible for making sure that all the dependent library files are actually installed.) > Also, I tried building a shared version (without --static) of qemu-2.11.0 and > it works fine. Problems with trying to build a statically linked QEMU usually mean: * QEMU needs and links against static library X * static library X depends on static library Y * but either you don't have the static version of Y installed (a bug in your distro's library packaging or dependencies, possibly) * or the pkg-config information that your distro ships with library X does not correctly declare that it depends on Y and so Y doesn't go on the list of libraries QEMU links with In this case all the "could not find -lfoo" errors suggests that it's the "you don't have the static library installed" case, and you should be able to fix this by installing the right static libs from your distro. In general, we provide --static for the benefit mostly of the user-mode emulation binaries, which have a very small list of library dependencies. Building the system emulation binaries with --static is rather chancier. The underlying reason for this kind of problem is that very few people try to statically link anything, and so bugs in distro packaging of statically linked libraries very rarely get reported or fixed. Sometimes distros don't provide static versions of some libraries at all. As usual, if you wander away from the beaten path you can run into thornbushes. I notice that your configure arguments are rather odd, which might be why you're running into trouble. (1) you pass --cpu=arm -- this is almost never a good idea. Let configure autodetect the host CPU for you. (2) you pass --target-list=mips-linux-user, which suggest you just want to build the mips user mode emulator, but then you also pass a lot of arguments which are only relevant for system emulation: --enable-system --enable-kvm --enable-gtk --enable-virtfs --enable-sdl --disable-vnc Some of these are going to cause configure to try to probe for things that mips-linux-user won't even use, and then complain that it can't find them. If all you want is mips-linux-user, drop all those other arguments. thanks -- PMM
