added --enable-threads=posix to chapter 5-gcc, updated chapter 6 from
--enable-threads to --enable-threads=posix (for clarity, since posix is the
default).

|

| 5 | This new patch deals with incorrect handling of weak symbols, the
|
|---|
| 6 | over-optimization of calls to those weak symbols, an atexit issue and
|
|---|
| 7 | the __dso_handle symbol required for atexit's proper function.</para>

| 9 | <para><userinput>make BOOT_LDFLAGS=-static:</userinput>
|
|---|
| 10 | This is the equivalent to make LDFLAGS=-static as we use with other
|
|---|
| 11 | packages to compile them statically.</para>
|

| 12 |
|
|---|
| 13 | <para><userinput>--prefix=/usr:</userinput> This is NOT a typo. GCC hard
|
|---|
| 14 | codes some paths while compiling and so we need to pass /usr as the
|
|---|
| 15 | prefix during ./configure. We pass the real install prefix during the
|
|---|
| 16 | make install command later.</para>

| 18 | <para><userinput>--enable-languages=c,c++:</userinput> This only builds the C
|
|---|
| 19 | and C++ compilers and not the other available compilers as they are, on
|
|---|
| 20 | the average, not often used. If those other compilers are needed,
|
|---|
| 21 | the --enable-languages parameter can be omitted.</para>

| 26 | <para><userinput>ln -sf ../usr/bin/cpp:</userinput> This
|

| 28 | cpp in /lib.</para>

|
|---|
| 30 | <para><userinput>ln -sf ../bin/cpp:</userinput> This
|
|---|
| 31 | creates the $LFS/usr/lib/cpp symlink as there are packages that expect

| 32 | cpp to be in /usr/lib.</para>
