Thread: Compiling libg15 - libusb not found though installed

  1. #1

    Default Compiling libg15 - libusb not found though installed

    Just installed OpenSuse 12.1, so I'm once again building the tools to support my G15 keyboard. This time though, configure is not finding libusb, though it is installed.

    I found a G15 repo on build.opensuse.org, at https://build.opensuse.org/project/s...na%3Ag15-tools but I'd rather build it myself, and I'd like to understand autoconf better and learn why it is not finding libusb.

    Configure does not appear to accept arguments for libusb_libs (nothing shown in configure --help, and no AC_ARG_WITH options defined in aclocal.m4?) I did try just using ./configure --libdir=/lib64 but libusb is still not found.

    It seems like automake is just not finding it, though I don't know why:
    Code:
    configure.in:AC_CHECK_LIB([usb], [main], ,AC_MSG_ERROR(["libusb not found. please install it"])
    Any help would be appreciated!

    Cheers,
    Pete

    All the gory details:

    Build Error:
    Code:
    svn co https://g15tools.svn.sourceforge.net/svnroot/g15tools g15tools-new
    cd g15tools-new/trunk/libg15
    ./bootstrap
    ./configure
    ...
    checking whether to build shared libraries... yes
    checking whether to build static libraries... yes
    checking for main in -lusb... no
    configure: error: "libusb not found. please install it"
    Installed libs:
    Code:
    rpm -qa | grep libusb
    libusb-1_0-0-1.0.8-9.1.2.x86_64
    libusb-0_1-4-0.1.13-14.1.2.x86_64
    libusb-1_0-devel-1.0.8-9.1.2.x86_64
    ld.so.conf is:
    Code:
    cat /etc/ld.so.conf
    /usr/local/lib64
    /usr/local/lib
    /lib64
    /usr/lib64
    include /etc/ld.so.conf.d/*.conf
    Where things are:
    Code:
    lrwxrwxrwx 1 root root    19 Nov 10 11:12 /lib64/libusb-0.1.so.4 -> libusb-0.1.so.4.4.4

    Did you search for the corresponding -devel library?

    Hi there,

    Yep - libusb-1_0-devel-1.0.8-9.1.2.x86_64 installed.

    Ah . . . it is written against libusb_0.1 and so libusb-compat-devel is needed to compile on 12.1

    That allowed libg15 and g15daemon to compiled, however when starting g15daemon it gave:

    Code:
    /home/paracelsus/compiled-packages/g15-rpms # g15daemon -d
    open(/usr/local/var/run/g15daemon.pid): No such file or directory
    Unable to create PID File! Exiting
    Looks like g15daemon now expects this directory path (it didn't use to), so simply create it:
    Code:
     mkdir -p /usr/local/var/run
    g15daemon now runs and the greeting message and clock are displayed! (Don''t forget modprobe uinput is needed)

    libg15render (from g15tools) also compiled fine, though you must use ./configure --prefix=/usr/local or you will get font errors when running clients (like g15stats) as the font dive will be undefined:
    Code:
    libg15render: Unable to load font "NONE/share/g15tools/fonts/G15/default-01.fnt"
    You can then do a zypper install libgtop libgtop-devel allowing g15stats (from g15-daemon clients) to compile.

    The g15 keyboard lives on for OpenSuse 12.1!

    Good! I mean good that you found it :-)

    It happens when you compile things locally, I think. Instead of the normal
    paths, they use /usr/local instead.

    Of those problems, I don't know.
