| 5 | This patch fixes a bug in gcc's linker concerning non-exported (weak)
|
|---|
| 6 | symbols, which was brought to the surface by the new glibc and also one
|
|---|
| 7 | or two other problems which can arise.</para>

| 9 | <para><userinput>--prefix=/usr:</userinput> This is NOT a typo. GCC hard
|
|---|
| 10 | codes some paths while compiling and so we need to pass /usr as the
|
|---|
| 11 | prefix during ./configure. We pass the real install prefix during the
|
|---|
| 12 | make install command later.</para>

| 14 | <para><userinput>--enable-languages=c,c++:</userinput> This only builds the C
|
|---|
| 15 | and C++ compilers and not the other available compilers as they are, on
|
|---|
| 16 | the average, not often used. If those other compilers are needed,
|
|---|
| 17 | the --enable-languages parameter can be omitted.</para>

| 21 | cpp in /lib.</para>
|

|

| 23 | <para><userinput>ln -s ../bin/cpp:</userinput> This
