<para><userinput>patch -Np1 -i ../gcc-&gcc-patch-version;.patch:</userinput>
|
|
This new patch deals with incorrect handling of weak symbols, the
|
|
over-optimization of calls to those weak symbols, an atexit issue and
|
|
the __dso_handle symbol required for atexit's proper function.</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>--prefix=/usr:</userinput> This is NOT a typo. GCC hard
|
|
codes some paths while compiling and so we need to pass /usr as the
|
|
prefix during ./configure. We pass the real install prefix during the
|
|
make install command later.</para>
|
|
|
|
<para><userinput>--enable-languages=c,c++:</userinput> This only builds the C
|
|
and C++ compilers and not the other available compilers as they are, on
|
|
the average, not often used. If those other compilers are needed,
|
|
the --enable-languages parameter can be omitted.</para>
|
|
|
|
<para><userinput>--enable-threads=posix:</userinput> This enables C++
|
|
exception handling for multithreaded code.</para>
|
|
|
|
<para><userinput>ln -sf ../usr/bin/cpp:</userinput> This
|
|
creates the $LFS/lib/cpp symlink. Some packages explicitly try to find
|
|
cpp in /lib.</para>
|
|
|
|
<para><userinput>ln -sf ../bin/cpp:</userinput> This
|
|
creates the $LFS/usr/lib/cpp symlink as there are packages that expect
|
|
cpp to be in /usr/lib.</para>
