Note that we want to give these sections the SHF_WRITE attribute

because these sections will actually contain data (i.e. tables of
|
|
addresses of functions in the current root executable or shared library
|
|
file) and, in the case of a shared library, the relocatable addresses
|
|
will have to be properly resolved/relocated (and then written into) by
|
|
the dynamic linker when it actually attaches the given shared library
|
|
to the executing process. (Note that on SVR4, you may wish to use the
|
|
`-z text' option to the ELF linker, when building a shared library, as
|
|
an additional check that you are doing everything right. But if you do
|
|
use the `-z text' option when building a shared library, you will get
|
|
errors unless the .ctors and .dtors sections are marked as writable
|
|
via the SHF_WRITE attribute.) */
