    How can I install libusb and libfprint from source code?

    Hi,

    I'm trying to install an application called fprint_demo without install any .deb package, and this application is dependent from three libs: (faster to install)libusb, (slow)imagemagick, (faster)libfprint.

    I will put all the installed things in /opt/manual and the fonts in /opt/install, I don't have and I don't want install the package libusb-dev.

    I started installing the libusb:
    Code:
    mkdir -r /opt/manual
    cd /opt/install/libusb-1.0.2/
     ./configure --prefix=/opt/manual --enable-debug-log
    .
    .
    .configure: creating ./config.status
    config.status: creating libusb-1.0.pc
    config.status: creating Makefile
    config.status: creating libusb/Makefile
    config.status: creating examples/Makefile
    config.status: creating doc/Makefile
    config.status: creating doc/doxygen.cfg
    config.status: creating config.h
    config.status: config.h is unchanged
    config.status: executing depfiles commands
    config.status: executing libtool commands
    (no errors)
    make
    .
    .
    .
    (no errors)
    sudo checkinstall -D
    .
    .
    .

    ok until here? next post I will show the Imagemagick install.

    Consider adjusting the PKG_CONFIG_PATH environment variable if you
    installed software in a non-standard prefix.
    
    Alternatively, you may set the environment variables LIBUSB_CFLAGS
    and LIBUSB_LIBS to avoid the need to call pkg-config.
    See the pkg-config man page for more details.
    Why this lib can't find where my libusb are installed ? ldconfig doesn't do that? How can I configure pkg-config to search for .pc files on /opt/manual/lib/pkg-config ??

    I have tried it as the documentation says
    Code:
    export PKG_CONFIG_PATH=/opt/manual/lib/pkgconfig/:$PKG_CONFIG_PATH
    but when I run ./configure the error persist.
    Bye!

    Re: How can I install libusb and libfprint form source code?

    I found the solution to compile Libfprint.

    Code:
    export PKG_CONFIG_PATH=/opt/manual/lib/pkgconfig/:$PKG_CONFIG_PATH
    echo $PKG_CONFIG_PATH
    /opt/manual/lib/pkgconfig/:
    then

    Code:
    pkg-config --cflags libusb-1.0 --libs libusb-1.0
    -I/opt/manual/include/libusb-1.0  -L/opt/manual/lib -lusb-1.0  
     ./configure --prefix=/opt/manual --enable-debug-log LIBUSB_CFLAGS=-I/opt/manual/include/libusb-1.0  LIBUSB_LIBS='-L/opt/manual/lib -lusb-1.0'
    .
    .
    .

    checking for IMAGEMAGICK... yes

    Why ImageMagick is found and libusb isn't I never you know rsrs.

    then more one critical error..

    The make is looking for a header called usb.h

    Code:
    find /opt/install/libusb-1.0.2/ /opt/manual/include/ -iname "usb.h"
    (nothing)
    What I can do now?

    Angry Re: How can I install libusb and libfprint form source code?

    I found the solution but isn't the best solution..
    I downloaded all libusb-x.x.x from the site www.libusb.org, and anyone of them does not had the "usb.h" header. Then I got an ideia, I download the .deb package to see if it had the file "usb.h"
    Code:
    sudo apt-get install -d libusb-dev
    sudo dpkg -x /var/cache/apt/archives/libusb-dev_2%3a0.1.12-13_i386.deb ~/libusb-dev
    find /home/maiko/libusb-dev/ -iname "usb.h"
    /home/maiko/libusb-dev/usr/include/usb.h
    Omg! Why ?!?!??!?!

    not even knowing why

    Code:
    sudo cp -a /home/maiko/libusb-dev/usr/include/usb.h /opt/manual/include/libusb-1.0/
    make
    .
    .
    .

    Noooo!

    I found this solution, in the gcc line what give the error says:
    main.c:22:30: error: libfprint/fprint.h: Arquivo ou diretório inexistente (file not found)
    Code:
    gcc -DPACKAGE_NAME=\"fprint_demo\" -DPACKAGE_TARNAME=\"fprint_demo\" -DPACKAGE_VERSION=\"0.4\" -DPACKAGE_STRING=\"fprint_demo\ 0.4\" -DPACKAGE_BUGREPORT=\"\" -DPACKAGE=\"fprint_demo\" -DVERSION=\"0.4\" -I.    -I/opt/manual/include/libfprint   -D_REENTRANT -I/usr/include/gtk-2.0 -I/usr/lib/gtk-2.0/include -I/usr/include/atk-1.0 -I/usr/include/cairo -I/usr/include/pango-1.0 -I/usr/include/pixman-1 -I/usr/include/freetype2 -I/usr/include/directfb -I/usr/include/libpng12 -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include   -g -O2 -MT fprint_demo-main.o -MD -MP -MF .deps/fprint_demo-main.Tpo -c -o fprint_demo-main.o `test -f 'main.c' || echo './'`main.c
    But in code the include is libfprint/fprint.h Then modify the configure to
    Code:
    ./configure --prefix=/opt/manual FPRINT_CFLAGS=-I/opt/manual/include/
    make
    gcc -I/opt/manual/include/ -D_REENTRANT -I/usr/include/gtk-2.0 -I/usr/lib/gtk-2.0/include -I/usr/include/atk-1.0 -I/usr/include/cairo -I/usr/include/pango-1.0 -I/usr/include/pixman-1 -I/usr/include/freetype2 -I/usr/include/directfb -I/usr/include/libpng12 -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include   -g -O2   -o fprint_demo fprint_demo-main.o fprint_demo-enroll.o fprint_demo-img.o fprint_demo-verify.o fprint_demo-identify.o -L/opt/manual/lib -lfprint   -lgtk-x11-2.0 -lgdk-x11-2.0 -latk-1.0 -lpangoft2-1.0 -lgdk_pixbuf-2.0 -lm -lpangocairo-1.0 -lgio-2.0 -lcairo -lpango-1.0 -lfreetype -lfontconfig -lgobject-2.0 -lgmodule-2.0 -lglib-2.0

    .
    .
