+The Hell of Autotools
+=====================
+    March 19, 2018
+In this trivial example we compile a custom **webkit2gtk+ extension** with 
+**autotools**. For a start we need to  provide two files, `Makefile.am` 
+and `configure.ac`, beside our actual `ext.c` source file, which contains 
+the extension code itself.
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ {.c .numberLines}
+// File: ext.c //
+
+#include <webkit2/webkit-web-extension.h>
+ 
+G_MODULE_EXPORT void
+webkit_web_extension_initialize_with_user_data (WebKitWebExtension *extension,
+                                                GVariant           *user_data)
+{
+    g_print("Hello Extension!\n");
+}
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ {.makefile .numberLines}
+# File: Makefile.am #
+
+webextension_LTLIBRARIES = libmyappwebextension.la
+webextensiondir = /home/miguel/temp
+ 
+WEB_EXTENSION_CFLAGS = `pkg-config --cflags webkit2gtk-web-extension-4.0`
+WEB_EXTENSION_LIBS2 = `pkg-config --libs webkit2gtk-web-extension-4.0`
+ 
+libmyappwebextension_la_SOURCES = ext.c
+libmyappwebextension_la_CFLAGS = $(WEB_EXTENSION_CFLAGS)
+libmyappwebextension_la_LIBADD = $(WEB_EXTENSION_LIBS)
+libmyappwebextension_la_LDFLAGS = -module -avoid-version -no-undefined $(WEB_EXTENSION_LIBS2)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ {.makefile .numberLines}
+# File: configure.ac #
+
+AC_PREREQ([2.69])
+AC_INIT(ext,0.1,test@example.com)
+AM_INIT_AUTOMAKE
+AC_CONFIG_SRCDIR([ext.c])
+AC_PROG_CC
+LT_INIT
+AC_CONFIG_FILES([Makefile])
+AC_OUTPUT
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Put the above files in a new fresh directory and you are ready to see the 
+powers of autotools in action. 
+
+Run the following commands on your pash prompt: 
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ {.bash}
+touch NEWS README AUTHORS ChangeLog
+aclocal
+autoconf
+automake --add-missing
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+After this steps, we end up with 18 files in our directory. Finally we 
+can _configure_, _build_ and _install_ our extension. The following 
+commands will probably look familiar. Note that the _configure_ step 
+generates 6 additional files, totaling in **24 files** before the actual 
+_make_ command is run.
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ {.bash}
+./configure 
+make
+make install
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+... just to compile one **single C file**.

+# Various Notes on Building
+
+## Webkit
+
+Let’s compile a release with debug info and install to /usr/local
+
+~~~~~~ {.bash}
+wget https://webkitgtk.org/releases/webkitgtk-2.20.0.tar.xz
+tar -xvf webkitgtk-2.20.0.tar.xz
+cd webkitgtk-2.20.0
+# install all the libs that will be reported missing in the next step.
+# I could not find the woff2 stuff in debian so skipped it... 
+cmake -DPORT=GTK -DCMAKE_BUILD_TYPE=RelWithDebInfo -DUSE_WOFF2=NO -GNinja
+# this takes about 30minutes on my i7-4790K .. zzzzz..zzz
+ninja
+sudo ninja install
+~~~~~~~~~~~
+
+    pkg-config
+
+    pkg-config uses our new build now:

+    [1] https://trac.webkit.org/wiki/BuildingGtk
+    [2] https://webkitgtk.org/
+
+## GCC
+
+This is how I build gcc (5.2.0) and binutils (2.25.1). Check [5] first.
+
+* unpack binutils-x.y.z
+* create a new directory binutils-x.y.z-build and inside it run the following commands:
+
+~~~~~~ {.bash}
+    $ ../binutils-x.y.z/configure --disable-nls --with-sysroot --enable-targets=all
+    $ make -j4
+    $ make install
+~~~~~~~~~~~~
+
+* unpack gcc-x.y.z and run the contrib/download_prerequisites script inside.
+* create a new directory: gcc-x.y.z-build and inside it run:
+    
+~~~~~~ {.bash}
+    $ ../gcc-x.y.z/configure --disable-nls --enable-languages=c,c++ --enable-threads
+    $ make -j4
+    $ make install
+~~~~~~~~~~~~

+## Linux
+
+    cd linux-source-[xxx]
+    make mrproper
+    cp someconfig .config -i
+    make oldconfig
+    make menuconfig
+    make localmodconfig
+    make localyesconfig

+    su
+    make install
+    (OPT) make modules_install
+    (OPT) update-intiramfs -c -k [kernel-postfix]
+
+    (REMOVE UNWANTED FILES FROM BOOT!)
+    update-grub
+    grub-install /dev/sda
+    reboot
+
+
+## Clang
+
+    http://llvm.org/releases/3.7.0/docs/CMake.html
+    http://clang.llvm.org/get_started.html
+    put MAKEFLAGS="-j8" or similar in front of your CMake invocations.
