    <title>Installation of uClibc Headers</title>

    <para os="a">By default uClibc symlinks all its headers from the source, we
    will change this behavious with the following sed:</para>
        
<screen os="b"><userinput>cp Makefile Makefile.orig
sed -e 's/$(LN) -fs/cp/g' Makefile.orig > Makefile
for file in `find libc/sysdeps/linux -name Makefile`; do
        cp $file $file.orig
        sed -e 's/$(LN) -fs/cp/g' -e 's@../libc/@$(TOPDIR)libc/@g' $file.orig > $file
done</userinput></screen>

    <para os="c">Now we will ask uClibc to create a default configuration:</para>

<screen os="d"><userinput>make defconfig</userinput></screen>

   <para os="e">Create the Headers:</para>

<screen os="f"><userinput>make KERNEL_SOURCE=${CLFS}/usr TARGET_ARCH=i386 headers</userinput></screen>

   <para os="g">We will remove the files that were copied over from our Linux Headers, these
   files were copied into the source directory of uClibc:</para>

<screen os="h"><userinput>rm include/{asm,asm-generic,linux}</userinput></screen>

   <para os="i">Install the Headers:</para>

<screen os="j"><userinput>cp -a include/* ${CLFS}/usr/include</userinput></screen>
