<para><userinput>patch -Np1 -i ../gcc-&gcc-patch-version;.patch:</userinput>
|
|
This patch fixes a few bug fixes. See
|
|
<ulink url="http://www.zipworld.com.au/~gschafer/lfs-tweaks.html"/> for
|
|
more details.</para>
|
|
|
|
<para><userinput>--prefix=/static:</userinput> This is NOT a typo. GCC hard
|
|
codes some paths while compiling and so we need to pass /static as the
|
|
prefix during ./configure. We pass the real install prefix during the
|
|
make install command later.</para>
|
|
|
|
<para><userinput>--enable-languages=c:</userinput> This builds the C
|
|
compiler. The C++ compiler will be built in chapter 6, when we rebuild
|
|
GCC. Other compilers are available as well. If they are needed,
|
|
the --enable-languages parameter may be omitted.</para>
|
|
|
|
<para><userinput>--enable-threads=posix:</userinput> This enables C++
|
|
exception handling for multithreaded code.</para>
|
|
|
|
<para><userinput>--enable-__cxa-atexit:</userinput> This option will result
|
|
in C++ shared libraries and C++ programs that are interoperable with other
|
|
linux distributions.</para>
|
|
|
|
<para><userinput>make BOOT_LDFLAGS=-static:</userinput>
|
|
This is the equivalent to make LDFLAGS=-static as we use with other
|
|
packages to compile them statically.</para>
|
|
|
|
<para><userinput>ln -s gcc $LFS/static/bin/cc:</userinput> This
|
|
creates the $LFS/static/bin/gcc symlink which some packages need.</para>
