To download the needed files using wget, use the following commands:

    mkdir lib &&
    cd lib &&
    grep -v '^#' ../lib-7.md5 | awk '{print $2}' | wget -i- -c \
        -B https://www.x.org/pub/individual/lib/ &&
    md5sum -c ../lib-7.md5

## Installation of Xorg Libraries

### Note

When installing multiple packages in a script, the installation needs to be done as the root user. There are three general options that can be used to do this:

1. Run the entire script as the root user (not recommended).

2. Use the sudo command from the Sudo-1.9.9 package.

3. Use su -c "command arguments" (quotes required) which will ask for the root password for every iteration of the loop.

One way to handle this situation is to create a short bash function that automatically selects the appropriate method. Once the command is set in the environment, it does not need to be set again.

    as_root()
    {
      if   [ $EUID = 0 ];        then $*
      elif [ -x /usr/bin/sudo ]; then sudo $*
      else                            su -c \\"$*\\"
      fi
    }

    export -f as_root

Some libraries come with a test suite. If you wish to execute them, either comment out the rm -rf ... below, so that, after all libraries are installed, you can come back to the corresponding directory and run make check, or do individual builds, running the tests for each of those distributed with working test suites. Alternatively, you can uncomment the line #make check ..., and at the end, check the test results with:

    grep -A9 summary *make_check.log

BLFS developers have confirmed that libX11, libXt and libxshmfence are distributed with working test suites.

First, start a subshell that will exit on error:

    bash -e

Install all of the packages by running the following commands:

    for package in $(grep -v '^#' ../lib-7.md5 | awk '{print $2}')
    do
      packagedir=${package%.tar.?z*}
      tar -xf $package
      pushd $packagedir
      docdir="--docdir=$XORG_PREFIX/share/doc/$packagedir"
      case $packagedir in
        libICE* )
          ./configure $XORG_CONFIG $docdir ICE_LIBS=-lpthread
        ;;

        libXfont2-[0-9]* )
          ./configure $XORG_CONFIG $docdir --disable-devel-docs
        ;;

        libXt-[0-9]* )
          ./configure $XORG_CONFIG $docdir \
                      --with-appdefaultdir=/etc/X11/app-defaults
        ;;

        * )
          ./configure $XORG_CONFIG $docdir
        ;;
      esac
      make
      #make check 2>&1 | tee ../$packagedir-make_check.log
      as_root make install
      popd
      rm -rf $packagedir
      as_root /sbin/ldconfig
    done

Finally, exit the shell that was started earlier:

    exit

## Command Explanations

./configure $XORG_CONFIG ICE_LIBS=-lpthread: This fixes a change in glibc which breaks pulseaudio at runtime.

`--disable-devel-docs`: Disable generation of text documentation in the libXfont2 package if xmlto-0.0.28 is installed without a text browser. Omit this parameter (or the entire case statement) if a text browser is installed.

`--with-fop`: Use fop-2.7 to generate PDF documentation (only for the libXfont package).

## Configuration of Xorg Libraries

If you've chosen to install Xorg into `/usr`, then no further configuration is necessary and you can skip the rest of this section. If you've opted for an alternate prefix, you should create two symlinks to satisfy the expected environment of several packages. Execute the following commands as the root user:

    ln -sv $XORG_PREFIX/lib/X11 /usr/lib/X11 &&
    ln -sv $XORG_PREFIX/include/X11 /usr/include/X11
