4<para><userinput>make BOOT_LDFLAGS=-static:</userinput>
5This is the equivalent to make LDFLAGS=-static as we use with other
6packages to compile them statically.</para>
7
8<para><userinput>--prefix=/usr:</userinput> This is NOT a typo. GCC hard
9codes some paths while compiling and so we need to pass /usr as the
10prefix during ./configure. We pass the real install prefix during the
11make install command later.</para>
12
13<para><userinput>--enable-languages=c,c++:</userinput> This only builds the C
14and C++ compilers and not the other available compilers as they are, on
15the average, not often used. If those other compilers are needed,
16the --enable-languages parameter can be omitted.</para>
17
18<para><userinput>--enable-threads=posix:</userinput> This enables C++
19exception handling for multithreaded code.</para>
20
21<para><userinput>ln -sf ../usr/bin/cpp:</userinput> This
22creates the $LFS/lib/cpp symlink. Some packages explicitly try to find
23cpp in /lib.</para>
24
25<para><userinput>ln -sf ../bin/cpp:</userinput> This
26creates the $LFS/usr/lib/cpp symlink as there are packages that expect
27cpp to be in /usr/lib.</para>
