How to configure, build, and install SANE-FRONTENDS. Quick install: ============== ./configure make make install Type `./configure --help' for a list of options. Prerequisites: - GNU make version 3.70 or later and an ANSI C-Compiler (e.g. gcc) is needed for compilation. It may be necessary to specify the path to GNU make and the compiler by setting the environment variables MAKE and CC before running configure. - You must install the sane-backends package before you can configure this package. If you use pre-compiled binaries (e.g. from your distribution) you will also have to install the SANE headers (maybe in a package called sane-devel or similar). In this case you also need the -devel packages for all the software sane-backends depends on (e.g. libusb). If you're lucky, your distribution took care of that. Otherwise run sane-config --libs and make sure that the -devel packages for all the libraries mentioned in the output are installed. - For xscanimage and xcam you need the X Window libraries and headers. Further more GTK version 0.99.13 (or 1.0.*, 1.2.*, 2.0.*) must be installed together with its header files. GTK can be found at http://www.gtk.org/. For some operating systems it's necessary to set the path to gtk-config explicitely. This can be done by using the environment variable GTK_CONFIG. For FreeBSD try `GTK_CONFIG=/usr/X11R6/bin/gtk12-config'. - If you want to use xscanimage as a GIMP plug-in, the GIMP libraries and headers are necessary. See http://www.gimp.org/. See also `man xscanimage'. Versions 1.0.*, 1.2.*, and 1.3.* are known to work. As the GIMP 1.3.* API is not stable yet, some versions may not work. Try using the latest one. - If you get an error message that libsane-dll.so.1 or libsane-so.1 is not found, you have to tell your system where the SANE-libraries are installed. On some systems the library directory `/usr/local/lib' is not searched by the system's dynamic library loader. If SANE is installed in `/usr/local/...' you have to tell your system's dynamic library loader to search in `/usr/local/lib'. For Linux: add the path `/usr/local/lib' to /etc/ld.so.conf and call ldconfig (as root). Another approach is to set the environment variable LD_LIBRARY_PATH (or the equivalent on other operating systems) to `/usr/local/lib'. - OS/2: If you get errors like this one: "xcam.o: Undefined symbol _pthread_write referenced from text segment", libpthread must be linked. Find "gtk-config" on your system and add "-lpthreads" to the list of libraries. Uninstall ========= To uninstall the binaries and manual pages, type `make uninstall'.
